Defendants.

Plaintiff’s Complaint and Demand

for Jury Trial

Civil Action No. 3:20-cv-157

COMPLAINT AND DEMAND FOR JURY TRIAL

Plaintiff DIANA HOLGUIN (hereinafter “Plaintiff”), by and through her attorneys, hereby 

files this, Plaintiff’s Complaint and Demand for Jury Trial, against Defendants COOK 

INCORPORATED, COOK MEDICAL LLC f/k/a COOK MEDICAL INCORPORATED; and 

COOK GROUP INCORPORATED, and alleges the following:

1. This is an action for damages relating to Defendants’ development, testing,

assembling, manufacture, packaging, labeling, preparing, distribution, marketing, supplying, 

and/or selling defective product sold under the name “inferior vena cava filter” (hereinafter “IVC 

filter”).

3. At all times relevant to this action, Cook intentionally, recklessly, and/or 

negligently failed to act as to the known failures and injuries associated with its devices and/or

failed to warn about and concealed , suppressed, omitted, and/or misrepresented the risks, dangers, 

defects and disadvantages of its IVC filters. 

4. At all times relevant to this action, Cook intentionally, recklessly, and/or 

negligently advertised, labeled, promoted, marketed, sold and/or distributed its IVC Filters as a 

safe medical device when in fact Cook had reason to know, and/or did know, that its IVC Filters 

were not safe for its intended purposes, and that its IVC Filters caused serious injury and death.

5. At all times relevant to this action, Cook is and was strictly liable for injuries caused 

by its IVC Filters because the devices are unreasonably dangerous and not accompanied by 

adequate warnings about its danger.

JURISDICTION AND VENUE

16. The Court has subject matter jurisdiction over this matter because there is complete 

diversity of citizenship between the parties given the parties are citizens of different states and the 

amount in controversy exceeds $75,000, exclusive of interest and costs. See 28 U.S.C. § 1332.

Specifically, as alleged in more detail in the PARTIES section, Plaintiff is a citizen of the State of 

Texas, while Cook Defendants are citizens of the State of Indiana. Cook Defendants are citizens 

of the State of Indiana given their principal place of business and state of incorporation, if 

applicable, is in Indiana. Additionally, the damages Plaintiff sustained as a result of the Cook 

Defendants’ wrongdoing substantially exceeds $75,000.

17. The Court has personal jurisdiction over the Cook Defendants because they have 

sufficient minimum contacts such that asserting jurisdiction over the defendants does not offend 

traditional notions of fair play and substantial justice. International Shoe v. Washington, 326 U.S. 

310, 325 (1945). The Cook Defendants have conducted and continue to conduct substantial and 

systematic business activities related to their IVC filters, in this jurisdiction. Such activities 

include, but are not limited to: (a) sales of IVC filters, including the Cook filter at issue in this 

case, in this jurisdiction; (b) hiring, training, and deploying employees, including managers and 

sales representatives, in this jurisdiction; (c) advertising and marketing of their IVC filters, 

Case 3:20-cv-00157 Document 1 Filed 06/04/20 Page 5 of 26
6

including the Cook filter at issue in this case, in this jurisdiction; (d) maintenance of company files 

and equipment relating to the Cook filter in this case, in this jurisdiction; (e) payment of employee 

salaries in this jurisdiction; and (f) maintenance of a website directed to all states, including Texas. 

The Cook Defendants also committed tortious acts within the State of Texas and caused injury to 

persons or property within the State of Texas arising out of acts or omissions by the Cook 

Defendant outside this state at or about the time of the Plaintiff’s injury, while the Cook Defendants 

were engaged in solicitation or service activities within the State of Texas; and/or, while products, 

materials, or things processed, serviced, or manufactured by the Cook Defendants were used or 

consumed within Texas in the ordinary course of commerce, trade, or use.

18. Venue is proper in this district because a substantial part of the events or omissions 

giving rise to Plaintiff’s claims occurred in this district. See 28 U.S.C. § 1391(b)(2). The Cook 

Defendants’ Cook filter was marketed, sold, and implanted in El Paso County in Texas. 

FACTUAL BACKGROUND

COOK INFERIOR VENA CAVA FILTERS GENERALLY

19. Defendants design, research, develop, manufacturer, test, market, advertise, 

promote, distribute, and sell products that are sold to and marketed to prevent, among other things, 

recurrent pulmonary embolism via placement in the vena cava. Defendants’ products include, the 

Cook Celect Vena Cava Filter and the Gunther Tulip Filter (collectively referred to herein as 

“Cook Filters”), which are introduced via a coaxial introducer sheath system.

20. Defendants sought Food and Drug Administration (“FDA”) approval to market the 

Cook Filters and/or its components under Section 510(k) of the Medical Device Amendment.

21. Section 510(k) allows marketing of medical devices if the device is substantially 

equivalent to other legally marketed predicate devices without formal review for the safety or 

Case 3:20-cv-00157 Document 1 Filed 06/04/20 Page 6 of 26
7

efficacy of the said device. The FDA explained the difference between the 510(k) process and the 

more rigorous “premarket approval” process in an amicus brief filed with the Third Circuit in Horn 

v. Thoratec Corp., 376 F.3d 163, 167 (3d Cir. 2004):

A manufacturer can obtain an FDA finding of “substantial equivalence” by 

submitting a premarket notification to the agency in accordance with section 

510(k)...A device found to be ‘substantially equivalent’ to a predicate device is 

said to be “cleared” by FDA (as opposed to “approved” by the agency under a 

[premarket approval]). A pre-market notification submitted under 510(k) is thus 

entirely different from a [pre-market approval] which must include data 

sufficient to demonstrate that the device is safe and effective. (Emphasis in 

original).

22. In Medtronic, Inc. v. Lohr, 518 U.S. 470,478-79 (1996), the Supreme Court 

similarly described the 510(k) process, observing:

If the FDA concludes on the basis of the [manufacturer’s] §510(k) notification that the 

device is ‘substantially equivalent’ to a pre-existing device, it can be marketed without 

further regulatory analysis...The §510(k) notification process is by no means comparable 

to the [premarket approval] process; in contract to the 1,200 hours necessary to complete a 

PMA review, the §510(k) review is completed in average of 20 hours...Section §510(k) 

notification requires little information, rarely elicits a negative response from the FDA, and 

gets process quickly.

23. An IVC filter, like the Cook Filters, is a device designed to filter blood clots (called 

“thrombi”) that travel from the lower portions of the body to the heart and lungs. IVC filters may 

be designed to be implanted, either temporarily or permanently, within the vena cava.

24. The inferior vena cava is a vein that returns blood to the heart from the lower portion 

of the body. In certain people, and for various reasons, thrombi travel from vessels in the legs and 

Case 3:20-cv-00157 Document 1 Filed 06/04/20 Page 7 of 26
8

pelvis, through the vena cava into the lungs. Often these thrombi develop in the deep leg veins. 

The thrombi are called “deep vein thrombosis” or DVT. Once the thrombi reach the lungs they are 

considered “pulmonary emboli” or PE. An IVC filter, like the Cook IVC Filters, is designed to 

prevent thromboembolic events.

25. The Cook Filters are retrievable filters.

26. The Cook Celect® Vena Cava Filter has four (4) anchoring struts for fixation and 

eight (8) independent secondary struts to improve self-centering and clot trapping.

27. The Gunther Tulip® Vena Cava Filter has a top hook and (4) anchoring struts for 

fixation and on each strut, it has a “flower” formation that is shorter than the strut where a wire 

piece branches out on each side of the strut forming an overall “flower” type formation on each 

strut.

28. At all times relevant hereto, the Cook Filters were widely advertised and promoted 

by the Defendants as safe and effective treatment for prevention of recurrent pulmonary embolism 

via placement in the vena cava. At all times relevant hereto, Defendants knew its Cook Filters 

were defective and knew that defect was attributable to the design’s failure to withstand the normal 

anatomical and physiological loading cycles exerted in vivo.

29. A retrospective review of all Cook Gunther Tulip Filters and Cook Celect filters 

retrieved between July 2006 and February 2008 was performed. One hundred and thirty (130) filter 

retrievals were attempted but in 33 cases, the standard retrieval technique failed. The authors 

concluded that “unsuccessful retrieval was due to significant endothelialization and caval

penetration” and that “hook endothelialization is the main factor resulting in failed retrieval and 

continues to be a limitation with these filters.” O. Doody, et al.; “Assessment of Snared-Loop 

Case 3:20-cv-00157 Document 1 Filed 06/04/20 Page 8 of 26
9

Technique When Standard Retrieval of Inferior Vena Cava Filters Fail” Cardiovasc 

Intervent Radiol (Sept 4, 2008 Technical Note).

30. A retrospective review of 115 patients who underwent Cook Celect IVC filter 

insertion between December 2005 and October 2007 was performed. While filter insertion was 

successful in all patients, the authors also concluded that “[f]ailed retrieval secondary to hook 

endothelialization continues to be an issue with this filter.” O. Doody, et al; Journal of Medical 

Imaging and Radiation Oncology “Initial Experience in 115 patients with the retrievable Cook 

Celect vena cava filter” 53 (2009) 64-68 (original article). 

31. In a review of clinical data related to 73 patients who had Celect IVC filter 

implanted between August 2007 and June 2008, the authors found that the Celect IVC filter was 

related to a high incidence of caval filter leg penetration. Immediately after fluoroscopy-guided 

filter deployment in 61 patients, four filters (6.5%) showed significant tilt. Follow-up abdominal 

CT in 18 patients demonstrated filter related problems in 7 (39%), which included penetration of 

filter legs in 4 and fracture/migration of filter components in 1.

32. In a study of Gunther Tulip and Celect IVC filters implanted between July 2007 

and May of 2009 reported by Cardiovascular Interventional Radiology electronically on March 

30, 2011 and published by journal in April 2012, one hundred percent of the Cook Celect filters 

and Gunther Tulip filters imaged after 71 days of implant caused some degree of filter perforation 

of the venal caval wall. Durack JC, et al, Cardiovasc Intervent Radiol., “Perforation of the IVC: 

rule rather than the exception after longer indwelling times for the Gunther Tulip and Celect

Retrievable Filters,” 2012 Apr.; 35(2):299-308. Epub 2011 Mar 30. The authors concluded: 

"Although infrequently reported in the clinical literature, clinical sequelae from IVC filter 

Case 3:20-cv-00157 Document 1 Filed 06/04/20 Page 9 of 26
10

components breaching the vena cava can be significant.” Defendants knew or should have known 

that their IVC filters were more likely than not to perforate the vena cava wall. 

33. This same study reported that tilt was seen in 20 out of 50 (40%) of the implanted 

Gunther Tulip and Celect IVC filters and all tilted filters also demonstrated vena caval perforation. 

Defendants knew or should have known that their IVC filters were more likely than not tilt and to 

perforate. 

34. While not inclusive of all medical studies published during the relevant time period, 

the above references show that the Defendants failed to disclose to physicians, patients and/or 

Plaintiff that its Cook Filters were subject to breakage, tilt, inability of removal, and migration 

even though they knew or should have known the same was true. 

35. At all times relevant hereto, the Defendants continued to promote the Cook Filter 

as safe and effective even when inadequate clinical trials had been performed to support long or 

short to safety and/or efficacy. 

36. The Defendants concealed the known risks and failed to warn of known or 

scientifically knowable dangers and risks associated with the Cook Filters, as aforesaid. 

37. The Cook Filters are constructed of conichrome. 

38. The Defendants specifically advertise the conichrome construction of the filter as a 

frame which “reduces the risk of fracture.” 

39. The failure of the Cook Filters is attributable, in part, to the fact that the Cook Filters 

suffer from a design defect causing it to be unable to withstand the normal anatomical and 

physiological loading cycles exerted in vivo. 

40. At all times relevant hereto, the Defendants failed to provide sufficient warnings 

and instructions that would have put Plaintiff and the general public on notice of the dangers and 

Case 3:20-cv-00157 Document 1 Filed 06/04/20 Page 10 of 26
11

adverse effects caused by implantation of the Cook Filters, including, but not limited to the 

design’s failure to withstand the normal anatomical and physiological loading cycles exerted in 

vivo.

41. The Cook Filters were designed, manufactured, distributed, sold and/or supplied by 

the Defendants, and were marketed while defective due to the inadequate warnings, instructions, 

labeling, and/or inadequate testing in light of Defendants’ knowledge of the products’ failure and 

serious adverse events. 

42. That at all times relevant hereto, the officers and/or directors of the Defendants 

named herein participated in, authorized and/or directed the production and promotion of the 

aforementioned products when they knew or should have known of the hazardous and dangerous 

propensities of the said products, and thereby actively participated in the tortious conduct that 

resulted in the injuries suffered by the Plaintiff.

PLAINTIFF’S COOK FILTER AND INJURIES

43. On or about May 21, 2008, Plaintiff Diana Holguin underwent a filter implant 

surgery whereby a Cook Gunther Tulip filter was implanted by Dr. Llewellyn Lee at William 

Beaumont Army Medical Center in El Paso, Texas. 

44. In June of 2018, Plaintiff underwent a computed tomography (“CT”) scan of her

abdomen and pelvis after complaining of pain and discomfort. The CT scan revealed that the Cook 

Filter struts had moved since the filter was placed, with several of the struts extending outside Ms. 

Holguin’s inferior vena cava. Additionally, the filter was noted to be tilted in Ms. Holguin’s 

inferior vena cava with the tip of the filter embedded in the wall of Ms. Holguin’s inferior vena 

cava. 

Case 3:20-cv-00157 Document 1 Filed 06/04/20 Page 11 of 26
12

45. Plaintiff is at risk for future Cook Filter fractures, migrations, perforations, and 

tilting. Plaintiff faces numerous health risks, including the risk of death. 

46. For the rest of her life, Plaintiff will require ongoing medical care and monitoring.

47. Plaintiff has also suffered significant, disfiguring injuries, including significant 

pain and distress restricting her ability to engage in activities of daily living.

48. Furthermore, Plaintiff has incurred substantial medical expenses as a result of

Cook’s defective device, and, on information and belief, she will continue to incur substantial 

medical expenses in the future. 

COUNT I: STRICT PRODUCTS LIABILITY – FAILURE TO WARN

49. Plaintiff repeats and realleges all previous paragraphs.

50. Cook Filters were defective and unreasonably dangerous when they left the 

possession of the Defendants in that they contained warnings insufficient to alert consumers, 

including Plaintiff, of the dangerous risks associated with the subject product, including but not 

limited to the risk of tilting, perforation, fracture and migration which are associated with and did 

cause serious injury and/or death.

51. Information provided by Cook to the medical community and to consumers 

concerning the safety and efficacy of its Cook Filters did not accurately reflect the serious and 

potentially fatal adverse events Plaintiff could suffer.

52. At all times relevant hereto, the Cook Filters were dangerous and presented a 

substantial danger to patients who were implanted with the Cook Filter, and these risks and dangers 

were known or knowable at the times of distribution and implantation in Plaintiff. Ordinary 

consumers would not have recognized the potential risks and dangers the Cook Filters posed to 

patients, because their use was specifically promoted to improve health of such patients.

Case 3:20-cv-00157 Document 1 Filed 06/04/20 Page 12 of 26
13

53. Had adequate warnings and instructions been provided, Plaintiff would not have 

been implanted with the Cook filter and would not have been at risk of the harmful injuries 

described herein. The Cook Defendants failed to provide warnings of such risks and dangers to 

Plaintiff and their medical providers as described herein. Neither Plaintiff, nor Plaintiff’s 

physicians knew, nor could they have learned through the exercise of reasonable care, the risks of

serious injury and/or death associated with and/or caused by Cooks’ Filters.

54. Cook Defendants knew or had knowledge that the warnings that were given failed 

to properly warn of the increased risks of serious injury and/or death associated with and/or caused 

by Cook Filters.

55. Plaintiff, individually and through her implanting physician, reasonably relied upon 

the skill, superior knowledge and judgment of the Cook Defendants.

56. Cook Defendants were under a continuing duty to warn Plaintiff and her physicians 

of the dangers associated with the filter.

57. Safer alternatives were available that were effective and without risks posed by 

Cook’s Filters.

58. As a direct and proximate result of the Cook Filter’s defects, as described herein, 

Plaintiff suffered permanent and continuous injuries, pain and suffering, disability and impairment. 

Plaintiff has suffered emotional trauma, harm and injuries that will continue into the future. 

Plaintiff has lost her ability to live a normal life and will continue to be so diminished into the 

future. Furthermore, Plaintiff has medical bills, both past and future, related to care because of the 

Cook Filters’ defects.

59. By reason of the foregoing, Cook Defendants are liable to Plaintiff for damages as 

a result of their failure to warn and/or adequately warn the Plaintiff and her healthcare 

Case 3:20-cv-00157 Document 1 Filed 06/04/20 Page 13 of 26
14

professionals about the increased risk of serious injury and death caused by their defective Cook 

filters.

60. WHEREFORE, Plaintiff demands judgment against the Cook Defendants and 

seeks damages, including compensatory damages, exemplary damages, and punitive damages, 

together with interest, the costs of suit and attorneys’ fees, and other such other and further relief 

as this Court deems just and proper.

COUNT II: STRICT PRODUCTS LIABILITY – DESIGN DEFECT

61. Plaintiff repeats and realleges all previous paragraphs.

62. Cook Defendants have a duty to provide adequate warnings and instructions for 

their products including their Cook Filters, to use reasonable care to design a product that is not 

unreasonably dangerous to users.

63. At all times relevant to this action, Cook Defendants designed, tested, 

manufactured, packaged, labeled, marketed, distributed, promoted and sold their Cook Filters, 

placing the devices into the stream of commerce.

64. At all times relevant to this action, Cook’s Filters were designed, tested, inspected, 

manufactured, assembled, developed, labeled, sterilized, licensed, marketed, advertised, 

promoted, sold, packaged, supplied and/or distributed by Cook Defendants in a condition that was 

defective and unreasonably dangerous to consumers, including Plaintiff.

65. Cook Filters are defective in their design and/or formulation in that they are not 

reasonably fit, suitable, or safe for its intended purpose and/or its foreseeable risks exceed the 

benefits associated with their design and formulation.

Case 3:20-cv-00157 Document 1 Filed 06/04/20 Page 14 of 26
15

66. Cook Filters were expected to reach, and did reach, users and/or consumers 

including Plaintiff, without substantial change in the defective and unreasonably dangerous 

condition in which they were manufactured and sold.

67. Physicians implanted as instructed via the Instructions for Use and in a foreseeable 

manner as normally intended, recommended, promoted, and marketed by the Cook Defendants. 

Plaintiff received and utilized Cook Filters in a foreseeable manner as normally intended 

recommend, promoted, and marketed by the Cook Defendants.

68. Cook Filters were and are unreasonably dangerous in that, as designed, failed to 

perform safely when used by ordinary consumers, including Plaintiff, including when the filters 

were used as intended and in a reasonably foreseeable manner.

69. Cook Filters were and are unreasonably dangerous and defective in design or 

formulation for their intended use in that, when they left the hands of the manufacturers and/or 

supplier, they posed a risk of serious vascular and other serious injury which could have been 

reduced or avoided, inter alia, by the adoption of a feasible reasonable alternative design. There 

were safer alternative designs for the like products.

70. Cook Filters were insufficiently tested and caused harmful adverse events that 

outweighed any potential utility.

71. Cook Filters, as manufactured and supplied, were defective due to inadequate 

warnings, and/or inadequate clinical trials, testing, and study, and inadequate reporting regarding 

the results of the clinical trials, testing and study.

72. Cook Filters, as manufactured and supplied, were defective due to its no longer 

being substantially equivalent to its predicate device with regard to safety and effectiveness.

Case 3:20-cv-00157 Document 1 Filed 06/04/20 Page 15 of 26
16

73. Cook Filters as manufactured and supplied by the Cook Defendants are and were 

defective due to inadequate post-marketing warnings or instructions because, after Cook 

Defendants knew or should have known of the risk of injuries from use and acquired additional 

knowledge and information confirming the defective and dangerous nature of its Cook Filters, 

Cook Defendants failed to provide adequate warnings to the medical community and the 

consumers, to whom Cook Defendants were directly marketing and advertising; and further, Cook 

Defendants continued to affirmatively promote their Cook Filters as safe and effective and as safe 

and effective as their predicate device.

74. As a direct and proximate result of the Cook Filter’s defects, as described herein, 

Plaintiff suffered permanent and continuous injuries, pain and suffering, disability and impairment. 

Plaintiff has suffered emotional trauma, harm and injuries that will continue into the future. 

Plaintiff has lost her ability to live a normal life and will continue to be so diminished into the 

future. Furthermore, Plaintiff has medical bills, both past and future, related to care because of the 

Cook Filters’ defects.

75. By reason of the foregoing, Cook Defendants are liable to Plaintiff for damages as 

a result of their failure to warn and/or adequately warn the Plaintiff and her healthcare 

professionals about the increased risk of serious injury and death caused by their defective Cook 

filters.

76. WHEREFORE, Plaintiff demands judgment against the Cook Defendants and 

seeks damages, including compensatory damages, exemplary damages, and punitive damages, 

together with interest, the costs of suit and attorneys’ fees, and other such other and further relief 

as this Court deems just and proper.

COUNT III: NEGLIGENCE

77. Plaintiff repeats and realleges all previous paragraphs.

78. At all times relevant to this cause of action, the Cook Defendants were in the 

business of designing, developing, manufacturing, marketing and selling sophisticated medical 

devices, including its Cook Filters.

79. At all times relevant hereto, the Cook Defendants were under a duty to act 

reasonably to design, develop, manufacture, market and sell a product that did not present a risk 

of harm or injury to the Plaintiff and to those people receiving their Filters.

80. At the time of manufacture and sale of the Cook Filters, the Cook Defendants knew 

or reasonably should have known the Cook Filters:

a. were designed and manufactured in such a manner so as to present an unreasonable 

risk of fracture of portions of the device, as aforesaid;

b. were designed and manufactured so as to present an unreasonable risk of migration 

of the device and/or portions of the device, as aforesaid;

c. were designed and manufactured to have unreasonable and insufficient strength or 

structural integrity to withstand normal placement within the human body; and/or

d. were designed and manufactured so as to present an unreasonable risk of 

perforation and damage to the vena caval wall.

81. Despite the aforementioned duty on the part of the Cook Defendants, they 

committed one or more breaches of their duty of reasonable care and were negligent in:

a. unreasonably and carelessly failing to properly warn of the dangers and risks of 

harm associated with the Cook Filters, specifically its incidents fracture, migration, 

perforation and other failure;

b. unreasonably and carelessly manufacturing a product that was insufficient in 

strength or structural integrity to withstand the foreseeable use of normal placement 

within the human body;

c. unreasonably and carelessly designed a product that was insufficient in strength or 

structural integrity to withstand the foreseeable use of normal placement within the 

human body; and

Case 3:20-cv-00157 Document 1 Filed 06/04/20 Page 17 of 26
18

d. unreasonably and carelessly designed a product that presented a risk of harm to the 

Plaintiff and others similarly situated in that it was prone to fail.

82. As a direct and proximate result of the Cook Filter’s defects, as described herein, 

Plaintiff has suffered permanent and continuous injuries, pain and suffering, disability and 

impairment. Plaintiff has suffered emotional trauma, harm and injuries that will continue into the 

future. Plaintiff has lost her ability to live a normal life, and will continue to be so diminished into

COUNT V: BREACH OF EXPRESS WARRANTY

89. Plaintiff repeats and realleges all previous paragraphs. Plaintiff, through her

medical providers, purchased her Cook Filter from the Cook Defendants. 

90. At all times relevant to this cause of action, the Cook Defendants were merchants 

of goods of the kind including medical devices and vena cava filters (i.e., Cook Filters). 

91. At the time and place of sale, distribution and supply of the Cook Filter to Plaintiff 

(and to other consumers and the medical community), Cook expressly represented and warranted 

in their marketing materials, both written and orally, and in the IFUs, that the Cook Filters were 

safe, well-tolerated, efficacious, and fit for their intended purpose and were of marketable quality, 

that they did not produce any unwarned-of dangerous side effects, and that they were adequately 

tested. 

92. At the time of Plaintiff’s purchase from the Cook Defendants, the Cook Filters was 

not in a merchantable condition and the Cook Defendants breached their expressed warranties, in 

that the filter:

a. was designed in such a manner so as to be prone to a unreasonably high incident of 

fracture, perforation of vessels and organs, and/or migration; 

b. was designed in such a manner so as to result in an unreasonably high incident of 

injury to the organs of its purchaser; and

c. was manufactured in such a manner so that the exterior surface of the Cook Filter 

was inadequately, improperly and inappropriately designed causing the device to 

weaken and fail.

93. As a direct and proximate result of the Cook Filter’s defects, as described herein, 

Plaintiff has suffered permanent and continuous injuries, pain and suffering, disability, and 

impairment. Plaintiff suffered emotional trauma, harm, and injuries that will continue into the

as a result of their breach express warranty

95. WHEREFORE, Plaintiff demands judgment against the Cook Defendants and 

seeks damages, including compensatory damages, exemplary damages, and punitive damages, 

together with interest, the costs of suit and attorneys’ fees, and other such other and further relief 

as this Court deems just and proper.

COUNT VI: BREACH OF IMPLIED WARRANTY

96. Plaintiff repeats and realleges all previous paragraphs.

97. At all relevant and material times, the Cook Defendants manufactured, distributed, 

advertised, promoted, and sold its Cook Filters.

98. At all relevant times, the Cook Defendants intended its Cook Filters be used in the 

manner that Plaintiff in fact used them.

99. Cook impliedly warranted their Cook Filters to be of merchantable quality, safe and 

fit for the use for which the Cook Defendants intended them and for which Plaintiff in fact used 

them.

100. The Cook Defendants breached their implied warranties as follows:

a. Cook failed to provide the warning or instruction and/or an adequate warning or 

instruction which a manufacturer exercising reasonable care would have provided 

concerning that risk, in light of the likelihood that its Cook Filters would cause 

harm;

b. Cook manufactured and/or sold their Cook Filters and said filters did not conform 

to representations made by the Cook Defendants when they left their control;

c. Cook manufactured and/or sold their Cook Filters which were more dangerous than

foreseeable manner, and the foreseeable risks associated with the Cook Filters’ 

Case 3:20-cv-00157 Document 1 Filed 06/04/20 Page 21 of 26
22

design or formulation exceeded the benefits associated with that design. These 

defects existed at the time the products left the Cook Defendants’ control; and

d. Cook manufactured and/or sold their Cook Filters when they deviated in a material 

way from the design specifications, formulas or performance standards or from 

otherwise identical units manufactured to the same design specifications, formulas, 

or performance standards, and these defects existed at the time the products left the 

Cook Defendants’ control.

101. The Cook Defendants’ marketing of their Cook Filters was false and/or misleading.

102. Plaintiff, through her attending physicians, relied on these representations in 

determining which IVC filter to use for implantation in the Plaintiff.

103. Cooks’ filters were unfit and unsafe for use by users as they posed an unreasonable 

and extreme risk of injury to persons using said products, such as the Plaintiff, and accordingly the 

Cook Defendants breached their expressed warranties and the implied warranties associated with 

the product.

104. The foregoing warranty breaches were a substantial factor in causing Plaintiff’s 

injuries and damages as alleged.

105. As a direct and proximate result of the Cook Filters’ defects, as described herein, 

Plaintiff has suffered permanent and continuous injuries, pain and suffering, disability and 

impairment. Plaintiff has suffered emotional trauma, harm and injuries that will continue into the

result of its breaches of implied warranty.

23

together with interest, the costs of suit and attorneys’ fees, and other such other and further relief 

as this Court deems just and proper.

COUNT VII: PUNITIVE DAMAGES

108. Plaintiff repeats and realleges all previous paragraphs.

109. At all times material hereto, the Cook Defendants knew or should have known their 

Cook Filters were inherently dangerous with respect to the risk of tilt, fracture, migration and/or 

perforation.

110. At all times material hereto, the Cook Defendants attempted to misrepresent and 

did knowingly misrepresent facts concerning the safety of their Cook Filters.

111. The Cook Defendants’ misrepresentations included knowingly withholding 

material information from the medical community and the public, including Plaintiff’s physicians, 

concerning the safety of their Cook Filters. The Cook Defendants’ conduct was willful, wanton, 

and undertaken with a conscious indifference to the consequences that consumers of their product 

faced, including Plaintiff.

112. At all times material hereto, Cook knew and recklessly disregarded the fact that 

their Cook IVC Filters have an unreasonably high rate of tilt, fracture, migration and/or 

perforation.

113. Notwithstanding the foregoing, the Cook Defendants continued to market their 

Cook Filters aggressively to consumers, including the Plaintiff, without disclosing the aforesaid 

side effects.

114. The Cook Defendants knew of their Cook Filters’ lack of warnings regarding the 

risk of fracture, migration, and/or perforation, but intentionally concealed and/or recklessly failed 

to disclose that risk and continued to market, distribute, and sell their Filters without said warnings 

Case 3:20-cv-00157 Document 1 Filed 06/04/20 Page 23 of 26
24

so as to maximize sales and profits at the expense of the health and safety of the public, including 

Plaintiff, in conscious disregard of the foreseeable harm caused by Cook Filters.

115. The Cook Defendants’ intentional and/or reckless failure to disclose information 

deprived the Plaintiff’s physicians of necessary information to enable them to weigh the true risks 

of using Cook Filters against their benefits.

116. As a direct and proximate result of the Cook Defendants’ willful, wanton, careless, 

reckless, conscious, and deliberate disregard for the safety and rights of consumers including the 

Plaintiff, the Plaintiff has suffered and will continue to suffer severe and permanent physical and 

emotional injuries, as described with particularity, above. Plaintiff has endured and will continue 

to endure pain, suffering, and loss of enjoyment of life; and has suffered and will continue to suffer 

economic loss, including incurring significant expenses for medical care and treatment and lost 

wages.

117. The Cook Defendants’ aforesaid conduct was committed with knowing, conscious, 

careless, reckless, willful, wanton, and deliberate disregard for the safety and rights of consumers 

including the Plaintiff, thereby entitling the Plaintiff to punitive damages in an amount appropriate 

to punish the Cook Defendants and deter them from similar conduct in the future.

118. WHEREFORE, Plaintiff demands judgment against the Cook Defendants and 

seeks damages, including compensatory damages, exemplary damages, and punitive damages, 

together with interest, the costs of suit and attorneys’ fees, and other such other and further relief 

as this Court deems just and proper.

Case 3:20-cv-00157 Document 1 Filed 06/04/20 Page 24 of 26

TOLLING OF THE LIMITATIONS PERIOD

119. The Cook Defendants, through their affirmative misrepresentations and omissions, 

actively concealed from the Plaintiff and Plaintiff’s healthcare providers the true and significant 

risks associated with Cook Filters.

120. As a result of the Cook Defendants’ actions, Plaintiff and her prescribing physicians 

were unaware, and could not have reasonably known or have learned through reasonable diligence, 

that Plaintiff had been exposed to the risks identified in this Complaint, and that those risks were 

the result of Defendants’ acts, omissions, and misrepresentations.

121. Accordingly, no limitations period ought to accrue until such time as Plaintiff knew 

or reasonably should have known of some causal connection between Plaintiff being implanted 

with a Cook Filter and the harm Plaintiff suffered as a result.

122. Additionally, the accrual and running of any applicable statute of limitations have 

been tolled by reason of the Cook Defendants’ fraudulent concealment.

123. Additionally, the Cook Defendants are equitably estopped from asserting any 

limitations defense by virtue of their fraudulent concealment and other misconduct as described.

124. Additionally, the limitations period ought to be tolled under principles of equitable 

tolling.

PRAYER FOR RELIEF

125. WHEREFORE, Plaintiff demands judgment against the Cook Defendants as

expenses; past and future pain and suffering; past and future emotional distress; 

past and future loss of enjoyment of life; past and future lost wages and loss of 

earning capacity; and consequential damages;
