This application is a continuation in part of and claims priority from U.S. patent application Ser. No. 10/741,875, filed Dec. 19, 2003 now U.S. Pat. No. 7,862,546, titled Subcutaneous Self Attaching Injection Port With Integral Moveable Retention Members. Application Ser. No. 10/741,875 claims priority from U.S. patent application Ser. No. 60/478,763, filed Jun. 16, 2003, titled Fluid Injection Port for Adjustable Gastric Band. This application incorporates by reference the following United States patent applications, all of which were filed on Dec. 19, 2003: application Ser. No. 10/741,127 titled Subcutaneous Injection Port For Applied Fasteners, published as U.S. Pub. No. 2005/0131352; application Ser. No. 10/741,875 titled Subcutaneous Self Attaching Injection Port With Integral Moveable Retention Members, published as U.S. Pub. No. 2004/0254537; and application Ser. No. 10/741,868 titled Subcutaneous Self Attaching Injection Port With Integral Fasteners, issued as U.S. Pat. No. 7,374,557.
FIGS. 14 and 15 illustrate a visual indicator of the state of the attachment mechanism. As seen in FIG. 14, indicia may be utilized, such as an unlocked lock icon 72 and a locked lock icon 74 molded integral with actuator ring 12. Any suitable graphic indicator may be used, and may be printed on or otherwise applied in a suitable manner. Port body 6 may include indicator 76 to provide a reference point for the movable indicia. An arrow may be included to indicate the bidirectional motion of actuator 12.
Tactile feedback can occur during assembly as well. During assembly, rotation of connector 40 about the tube 36 and fitting 34 requires a generally uniform rotary torque. Tactile feedback may be provided by causing a change in an attachment force or rotary torque applied to connector 40. The rotational torque increase can occur near the end of the assembly procedure and may be a suitable increase in rotational torque such as about 3% to 400% when tab 40 a creates an interference with detent edge 78 d. This interference creates a torque increase that rises to a maximum torque as the cantilever portion of extension 78 (containing detent edge 78 d) deflects to allow passage of tab 40 a. The maximum torque value may be followed by a torque drop such as immediately occurs when tab 40 a rotates past detent edge 78 d, and just before tab 40 b can come to a hard stop against extension 78 preventing further rotation of connector 40. The torque drop can be back to the original generally uniform torque needed to rotate connector 40 about the tube 36. Thus, during the assembly of connector 40 onto port body 6 to capture tube 36, the surgeon can experience a series of tactile and auditory events that provide indicators as to the success of the assembly or locking process, even when the assembly or locking event is obscured from visibility.
wherein said deflectable extension has at least one detent edge to create interference with said first tab as said first tab is rotated past said detent edge to a locked position, wherein the surgical implant is further configured to provide an unobstructed path for said second tab to travel through as said first tab is rotated past said detent edge from the unlocked position to the locked position.
2. The locking mechanism of claim 1 wherein said feedback is an audible signal.
3. The locking mechanism of claim 1 wherein said feedback is a tactile signal.
4. The locking mechanism of claim 3 wherein said tactile signal is an increase in torque between about 3 percent and about 400 percent.
5. The locking mechanism of claim 3 wherein said tactile signal is an increase in torque followed by a drop in torque.
6. The locking mechanism of claim 5 wherein said tactile signal of a drop in torque is followed by a hard stop.
7. The locking mechanism of claim 3 wherein said tactile signal is at least two selected from the group of an increase in torque, a decrease in torque and a hard stop.
8. The locking mechanism of claim 1 wherein said feedback is both a tactile signal and an audible signal.
9. The locking mechanism of claim 1 wherein said catheter includes a gastric band.
wherein said step of securing said catheter to said surgical implant with said locking mechanism includes deflecting a detent edge of said deformable slot with said first tab, wherein said second tab travels through an unobstructed path as the said detent edge is being deflected by said first tab during the act of securing said catheter to said surgical implant.
11. The method of claim 10 wherein said step of securing said catheter to said surgical implant includes deflecting and releasing said deflectable extension of said surgical implant.
12. The method of claim 10 wherein said step of securing said catheter to said surgical implant produces an audible feedback detectable by said surgeon.
13. The method of claim 10 wherein said step of securing said catheter to said surgical implant produces a tactile feedback detectable by said surgeon.
14. The method of claim 13 wherein said tactile feedback is an increase in torque between about 3 percent and about 400 percent.
15. The method of claim 13 wherein said tactile feedback is an increase in torque followed by a drop in torque.
16. The method of claim 15 wherein said tactile feedback of a drop in torque is followed by a hard stop.
17. The method of claim 13 wherein said tactile feedback is at least two selected from the group of an increase in torque, a decrease in torque, and a hard stop.
18. The method of claim 10 wherein said feedback is both a tactile signal and an audible signal.
