Abstract
A suture assembly includes a translation assembly that is axially translatable within a working channel of an endoscope and is adapted to releasably secure and/or release a needle and a distal end cap that is securable to an end of the endoscope and is adapted to releasably secure and/or release the needle in order to pass the needle back and forth between the translation assembly and the distal cap. An attachment mechanism configured to releasably secure the distal endcap to an end of the endoscope.
Claims20
A suture assembly for use in combination with an endoscope having a working channel and a distal end, the suture assembly comprising:
- a suturing assembly adapted to transfer a needle back and forth through tissue, the needle carrying a suture, the suturing assembly having a fixation flange disposed near a proximal end of the suturing assembly;
- and
- a split ring device disposable over an exterior of the endoscope proximate the distal end of the endoscope, the split ring device including a cylindrical inner surface adapted to frictionally engage an outer surface of the endoscope, and an annular slot adapted to engage the fixation flange of the suturing assembly in an interference fit.
A suture assembly for use in combination with an endoscope having a working channel and a distal end, the suture assembly comprising:
- a suturing assembly adapted to transfer a needle back and forth through tissue, the needle carrying a suture, the suturing assembly including a proximal connector adapted to be secured relative to the distal end of the endoscope;
- and
- a split ring device disposable over the proximal connector of the suture assembly and an exterior of the endoscope proximate the distal end of the endoscope, the split ring device including a cylindrical inner surface adapted to frictionally engage an outer surface of the proximal connector of the suture assembly in an interference fit, and an outer surface of the endoscope in a compressive fit.
A medical device assembly for use in combination with an endoscope, the assembly comprising:
- a medical device having a proximal end configured to be releasably securable to a distal end of the endoscope, and a distal end;
- and
- a split ring device disposable over the proximal end of the medical device and an exterior of the endoscope proximate the distal end of the endoscope, the split ring device including a cylindrical inner surface adapted to frictionally engage an outer surface of the proximal end of the medical device in an interference fit, and an outer surface of the endoscope in a compressive fit.
