The present invention relates generally to the field of catheter systems for performing diagnostic and / or interventional procedures. In particular, the present invention relates to a blood flow stop valve (Hemostasis valve) for controlling a guide catheter in a robot-operated catheter system.
Vascular diseases, and in particular cardiovascular diseases, are treated in various ways. Surgery, such as cardiac bypass surgery, is one method for treating cardiovascular disease. However, under certain circumstances, vascular disease is treated with a catheter based on an intervention procedure such as angioplasty. Intervention-based catheters are generally considered less invasive than surgery.
During one type of interventional procedure, a guide catheter is inserted from the patient's femoral artery and positioned proximal to the coronary ostium of the patient's heart. A guide wire is typically inserted through the blood flow stop valve into the patient's femoral artery and manipulated through the patient's arterial system until the guide wire reaches the injury location. Working catheters such as balloons and stents are then moved along the guidewire until they are positioned near the lesion to open the occlusion so as to increase blood flow near the lesion. In addition to cardiovascular disease, other diseases may also be treated with the catheter insertion process.

In one implementation, the working catheter mechanism 28 and guidewire mechanism 30 are of the type described in US Pat. No. 7,887,549, entitled “Catheter System”, which is incorporated herein by reference in its entirety. is there.
With reference to FIGS. 3-5, the guide catheter mechanism 26 includes a base 32 configured to removably receive a blood flow stop valve 34 and a guide catheter rotation drive 36. The base 32 includes a quick release mechanism for detachably attaching the blood flow stop valve 34 to the base 32. One implementation of a guide catheter quick release is disclosed in US Application Publication No. 2012/0179032 entitled “Remote Catheter System with Operatable Catheter”, which is hereby incorporated by reference in its entirety.
The blood flow stop valve 34 includes a first leg 38 having a distal end 40 and a proximal end 42. The second leg 44 extends from the first leg 38 and is in fluid communication with the first leg 38 such that fluid is introduced at the proximal end 46 of the second leg 44. The first leg 38 of the blood flow stop valve defines a longitudinal axis 50 that extends from the proximal end 42 of the first leg 38 to the distal end 40 of the first leg 38.
The distal end 40 of the first leg 38 includes a rotating luer connector 48 that is rotatably connected to the distal end 40 of the first leg 38. The rotary luer connector 48 includes an inner region 54 having a luer female interface for removably connecting an outer surface 52 and a guide catheter. Luer connectors are well known in the art and provide a fluid-free communication between the guide catheter and the blood flow stop valve. Luer connectors are protected by standards such as ISO 594 (including sections 594-1 and 594-2) and EN 1707.
In one implementation, the outer surface 52 of the rotary luer connector 48 includes a gear 56 that is driven by the rotary drive 36. The gear 56 is formed integrally with the rotary luer connector 48 and is connected to a drive gear 58 for rotational operation of the rotary connector.
In other implementations, the gear 56 is attached to the outer surface of the rotary luer connector 48 so that the gear 56 rotates with rotation about the longitudinal axis 50 of the first leg 38 of the blood flow stop valve 34.
Gears 56 and 58 provide direct rotation of driven gear 56 from a shaft that is rotated by motor 60 and extends along an axis 62 that is orthogonal to longitudinal axis 50 of first leg 38 of blood flow stop valve 34. Beveled gears or miter gears. With reference to FIG. 1, the gear 56 is beveled such that the gear teeth 64 extend in the direction toward the proximal end 42 and away from the distal end 40 of the first leg 38. In addition, the driven gear 56 is at a predetermined distance from the distal end 40 to allow the guide catheter to be attached to and removed from the rotary luer connector 48 in one embodiment. Be placed. The drive gear 58 is positioned under the first leg 38 so that the blood flow stop valve 34 can be easily removed from the base 32.
The motor 60 is attached to the base 32 such that the drive gear 58 is disposed on the first surface 66 of the base 32 and the motor 60 is disposed below the opposing second surface 68 of the base 32. The first surface 66 is closer to the first leg 38 than the second surface 68 of the base 32.
With reference to FIGS. 1 and 6, the second leg 44 of the blood flow stop valve 34 extends longitudinally along the second leg 44 from the proximal end 46 to the distal end 72 proximate to the first leg 38. It has a direction axis 70. The second leg working plane is defined by the axis 50 of the first leg 38 and the axis 70 of the second leg 44. In one implementation, the blood flow stop valve 34 is attached to the base 32 such that the second leg working plane is not orthogonal to the horizontal defined by gravity. Rather, the second working plane forms an acute angle with respect to the vertical plane to allow operator access to the proximal end 46 of the second leg 44. In one embodiment, the second working plane is the same plane as the horizontal plane. As described above, the blood flow stop valve 34 is releasably connected to the base 32 with a click release that allows the blood flow stop valve 34 to be removed from the base 32.
Referring to FIG. 5, the base 32 has an upstanding wall 74 that extends vertically upward from the surface 66. When the blood flow stop valve 34 is attached to the base 32, the wall 74 extends in a direction parallel to the axis 50 of the blood flow stop valve 34. The wall 74 is proximate to the rear portion 76 of the base 32 and is far from the front portion 78 of the base 32. Gear 58 is intermediate between wall 74 and front portion 78 of base 32. When the blood flow stop valve 34 is attached to the base 32, the guide member 80 is attached to the wall 74 and extends in a direction generally parallel to the axis 50. The guide member 80 has a guide portion 82 that is configured to direct a portion of the guide catheter toward the sleeve 84 before the guide catheter enters the sleeve 84.
Referring to FIGS. 3 and 10, the track 86 has a channel 88. An adjusting screw 90 or other type of fastener extends into the channel 88 through the track 86 to attach the sleeve 84. In one embodiment, the sleeve 84 includes a first wall 92, a second wall 94, and a third wall 96 extending from the first wall 92 to form a cavity 98. The opening 100 is defined as a space between the two free ends of the second wall 94 and the third wall 96. In other implementations, the sleeve 84 may be formed by a single arcuate wall member having an opening 100. A disposable sterilized barrier sleeve, such as a plastic sleeve, may be placed around the track 86 so that the sleeve 84 is disconnected from the track 86. The sleeve 84 is a one-time device and is discarded once the medical treatment using the sleeve is complete. In another embodiment, if the sleeve 84 is not placed in the channel 88, a sterile sterile barrier is instead placed in the channel 88 to isolate the guide catheter from the walls of the channel 88. In other implementations, if a sleeve or sterilization barrier is not used, the track 86 is discarded after use and replaced for other patients or prior to use of the bedside system for other procedures. It is a device that can be used only once.
With reference to FIGS. 7 and 8, the track 86 includes a distal end 102 disposed proximate to the patient and an opposite proximal end 104. The longitudinal axis 106 of the track is defined by the longitudinal axis of the track 86 that extends between the proximal end 104 and the distal end 102. In one implementation, the longitudinal axis 106 of the track and the longitudinal axis 50 of the blood flow stop valve form an acute angle 108. In one implementation, angle 108 is preferably an angle between 25 ° and 45 °, more preferably an angle between 30 ° and 45 °. In one implementation, the angle 108 is 30 degrees.
In one implementation, the plane track longitudinal axis 106 forms an acute angle 112 in the horizontal plane defined by the horizontal plane of the bed or the attraction indicating the treatment surface on which the patient lies. The longitudinal axis 106 of the track and the longitudinal axis 50 of the first leg of the blood flow stop valve form a plane 110. In one implementation, the plane 110 is at an acute angle 108 with respect to the horizontal plane. In other implementations, the angle formed between the plane 110 and the horizontal plane is an acute angle that is different from the angle formed by the longitudinal axis 106 and the horizontal plane.
With reference to FIGS. 7 and 8, the guide catheter mechanism 26 is offset to one side of the track 86 so that the plane 110 is not perpendicular to the horizontal plane. In other implementations, the guide catheter mechanism 26 is positioned closer to the operator than the track 86. In other words, when the operator operates the guide catheter mechanism 26, the operator is closer to the guide catheter mechanism than the track.
Referring to FIG. 3, in one embodiment, the track 86, guide catheter mechanism 26 and cassette 118 are accessible by an operator with the guide catheter mechanism 26 and cassette 118 facing the guide catheter mechanism 26 and cassette 118. For ease, it is rotated down about the y-axis. In one implementation, the vector designated as x is orthogonal to the longitudinal axis 106 extending through the channel 88 and forms an angle 166 below the horizontal plane. In one implementation, the angle 166 is 15 degrees below the horizontal plane defined by gravity. In one implementation, the operator is located proximate to the first side of the patient's bed. The support is located on the side of the bed that is normally opposite the first side. Cassette 118 and guide catheter mechanism 26 are closer to the first side of the patient's bed than to track 86. This allows an operator or physician to easily access the cassette 118 and guide catheter mechanism 26. The cassette 118 and the guide catheter mechanism 26 are placed on the patient 118 such that a portion of the cassette 118 and the guide catheter mechanism 26 proximate the track 86 is vertically higher than a portion of the cassette 118 and the guide catheter mechanism 26 furthest from the track 86. Tilt down toward the bed. Further, by pivoting the guide catheter mechanism 26 and cassette 118 from the longitudinal axis 106 at an angle 108, the guide catheter mechanism 26 and cassette 118 are placed in a position that allows access by an operator and / or physician.
The track 86 is fixed to the bedside support 114 and is maintained in a fixed position with respect to the patient bed 22. During catheterization, the bedside support 114 is positioned on the patient bed 22 so that the track 86 is at a fixed location relative to the patient bed 22 or at a fixed location relative to the patient on the patient bed 22. Fixed directly to one side, fixed to the patient bed 22 or fixed to a floor-mounted support located on the floor adjacent to the patient bed 22. In one implementation, the direction of the track 86 is adjusted relative to the patient bed 22 so that the angle 112 is adjusted as well. In another embodiment, angle 112 is between 10 ° and 45 °, and in one embodiment, angle 112 is 30 °.
Referring to FIG. 12, the guide catheter mechanism 26 is attached to a linear actuator 116 for moving the guide catheter mechanism along an axis parallel to the track axis 106 or along a common axis with the track axis 106. The linear actuator 116 provides intermittent increasing or continuous movement. In one embodiment, the linear actuator includes a rack and a pinion, and in another embodiment, includes a robotic arm. The linear actuator 116 moves independently with respect to the track 86. As described above, the working catheter mechanism 28 and the guide wire mechanism 30 are contained in a cassette 118 that is operatively and removably attached to the base member 120. Since base member 120 and guide catheter mechanism 26 are operably attached to linear actuator 116 with support 164, guide catheter mechanism 26, working catheter mechanism 28, and guidewire mechanism 30 all move along a linear axis. .
The operation of the guide catheter mechanism 26 during the catheter procedure will be described using a specific embodiment. The patient in need of catheterization will lie on his back on the patient bed 22. An opening in the femoral artery will be provided for the introduction of the guide catheter 122.
The track 86 is positioned relative to the patient such that the distal end 102 of the track 86 is positioned proximate to the patient's femoral artery. Cover 86 is covered by a sterilization barrier and a one-time use sleeve 84 is positioned in channel 88. Typically, the track 86 is covered by a sterilization barrier prior to being positioned with respect to the patient. Once the sleeve 84 is positioned in the channel 88, the sterilization barrier is positioned in the channel 88 so that the sterilization barrier provides a guard against fluid exposed to the sleeve 84 from contacting the track 86. The sleeve 84 has a distal end 124 and a proximal end 126. The distal end 124 of the sleeve 84 is disposed proximate to the distal end 102 of the track 86. In one implementation, the sleeve 84 is disposed within the channel 88 of the track 86 and thus has a specific shape to facilitate entry or removal of a portion of the guide catheter 122.
In a single catheter procedure on the patient's heart, an appropriate length guide catheter 122 is selected based on the patient's size. Guide catheter 122 has a proximal end 128 and a distal end 130. In one implementation, the proximal end 128 is first connected to the rotating luer connector 48 of the blood flow stop valve 34. The distal end 130 is then inserted into the patient's femoral artery and the distal end 130 of the guide catheter 122 is positioned near the heart ostium. The proximal end 128 of the guide catheter 122 may be connected to the rotational luer connector 48 after the distal end 130 is positioned near the heart ostium.
Once the guide catheter 122 is properly positioned with respect to the patient's heart, the central portion 132 of the guide catheter 122 that is positioned outside the patient is the central portion 132 of the guide catheter 122 through the opening 100 in the cavity 98. By being pushed in, it is placed in the sleeve 84.
Referring to FIGS. 9 and 11, the entry 134 of the guide catheter 122 will be exposed between the distal end 124 of the track 86 and the patient. Further, a coupling 136 adjacent the proximal end 124 of the guide catheter 122 extends outwardly from the sleeve 84 and track 86 in a direction toward the guide catheter mechanism. In one implementation, the coupling portion 136 has a length sufficient to allow the guide catheter hub to be coupled to the rotating luer 52 and has a length sufficient to bend into the track 86. . The coupling 136 extends outwardly from the sleeve 84 at an angle between about 25 ° to 45 ° and 30 °, between 30 ° and 45 °, and further 30 °.

To turn the drive gear 58 clockwise or counterclockwise, the operator rotates the guide catheter 122 by providing a control signal to the motor 60. As a result, the driven gear 56 rotates to cause rotation of the rotary luer connector 48 and rotation of the guide catheter 122. In addition to the conditions for rotating the guide catheter 122, the guide catheter 122 is moved along the track axis 106 to properly position the distal end 124 of the guide catheter 122 during the catheter procedure. The workstation comprises a user interface, such as a joystick, button, touch screen or other user interface, for controlling the linear actuator to move the guide catheter mechanism 26 in a generally parallel direction along the track axis 106. May be. Movement in a first direction parallel to the track axis causes further movement of the guide catheter 122 to the patient, and movement in the second direction opposite the linear translator causes movement of the guide catheter 122 to the outside of the patient. Bring.

The first pulley 146 may have a plurality of teeth that mesh with the ribs on the belt 148, and the outer surface 150 of the rotary luer connector 154 may have a plurality of teeth that mesh with the ribs on the belt 148. With this specification, control of the motor 144 allows controlled rotation of the rotating luer connector 156 in the clockwise and counterclockwise directions, thereby causing the guide catheter 122 attached to the rotating luer connector 156 to rotate. In one implementation, the pulley 152 and the bevel gear 56 are integrally formed on the outer surface of the rotary luer connector. However, it is also conceivable that a collet having an outer surface defining a pulley or bevel gear is attached to the outer surface of the rotary luer connector.
Referring to FIG. 14, in another implementation, luer expansion member 158 serves to connect proximal end 128 of guide catheter 122 to rotating luer connector 48. Luer extension member 158 includes an outer surface having a gear 160 or pulley member for operatively connecting to rotary drive motor 60 through drive gear 58. In this embodiment, the rotary drive motor is operatively connected to the outer surface of the luer extension member, but is not directly connected to the outer surface of the rotary luer connector. This allows the current and commercial use of the blood flow stop valve. In yet another embodiment, the luer expansion member does not require the distal end of the blood flow stop valve to have a rotating luer connector and requires a non-rotating luer connector. The extension 158 includes a female luer connector on the distal end for removably receiving a male luer that engages on the guide catheter. The extension 158 further comprises a male luer connector on the proximal end that is removably received within the female luer connector of the rotary connector on the blood flow stop valve.

Thereby, even if the guide catheter 122 rotates, the position of the 2nd leg 44 of the blood flow stop valve 34 does not change. Bracket 190 interacts with groove 182 at extension 158 to provide support as the guide catheter rotates and is attached to either base 32 or wall 74. The blood flow stop valve 34 is supported by a bracket 192 that is attached to either the base 32 or the wall 74. Two brackets 190 and 192 provide stability to the longitudinal axis 50 of the blood flow stop valve. The distal end 128 of the guide catheter 122 provides an expansion member 158 to the luer interlock. Guide member 80 and track 86 provide support to guide catheter 122 distally away from dilating member 158 and further toward patient bed 22, as shown in FIG. . As shown in FIG. 22, other means are used to transmit rotation to the expansion member 158, but the expansion member 158 is on a bevel gear face 160 that is rotated by the drive gear 58 to transmit rotation to the guide catheter 122. Provided. The drive gear 58 is rotated by the motor 60.

The internal component 170 further includes a female luer lock that forms a rotational fluid tight seal with the protrusion 41 on the valve 40. The inner part 170 is frictionally supplemented by a bore in the outer part 180 having a collar 184 that assists in defining a groove 182 that interacts with the bracket 190. The external part 180 further carries a bevel gear face 160. Frictional supplementation of the internal part 170 allows the external part 180 to easily transmit rotational motion to the internal part 170. Alternatively, the inner part 170 and the outer part 180 may be molded as a single object.
Referring to FIG. 21, the combined structure of the guide catheter 122, expansion member 158 and valve 134 is shown along the transverse line 21-21 of FIG. The second leg 44 of the blood flow stop valve 34 has a proximal end 46, a distal end 72 and a longitudinal axis 70. Inner part 170 fits within the bore of outer part 180. While the female luer lock 174 forms a fluid tight rotational seal with the protrusion 41 on the distal end 40 of the blood flow stop valve 34, the male luer lock 172 meshes with the receptacle 129 at the proximal end 128 of the guide catheter 122. To do. A continuous fluid path is formed from the proximal end 42 of the blood flow stop valve 34 to the bore of the guide catheter 122.
Referring to FIG. 22, it can be seen that another expansion member 159 is used to transmit rotational motion to the guide catheter 122 without mounting a gear wheel. The drive gear 58 drives a gear 160 that frictionally engages the outer surface of the other expansion member 159 with the O-ring 200. The gear 160 can be mounted with any frictional transmission means that interacts with other expansion members 159. The other expansion member 159 has a male luer lock 174 that meshes with the blood flow stop valve 34 to form a rotational seal.
