Appl. No.:

18/078205

Inventors:

- Fremont CA, US
Stephen J. PETER - San Francisco CA, US

International Classification:

A61B 17/04
A61B 17/06

Abstract:

Suture passer devices and methods of using the devices having one or more protective interlocks preventing or limiting operation of the suture passer when deployment of the needle may damage the apparatus or harm the patient. For example, described herein are suture passer devices that include an interlock preventing deployment of the tissue penetrator (needle) when the jaws are not clamped onto a tissue. Also described herein are interlocks preventing retraction of a jaw axially until the needle is retracted.

International Classification:

A61B 17/04
A61B 17/062

Abstract:

Suture passers and methods of use. Described herein are suture passers preloaded with suture, including cartridges that couple to a suture passer to form a loaded suture passer that are configured to prevent a length of suture (e.g., already-passed suture) from re-entering the channel of the suture passer jaw and getting recaptured and/or entangled by the tissue penetrator. In particular, described herein are preloaded and automatically re-loading suture passers that are adapted to include a gate, guide or shield on one of the jaws of the suture passer, and methods of operating such suture passers for surgical use including repairing tissue.

International Classification:

A61B 17/04

Abstract:

Described herein suture passer apparatus (devices and systems) that may be used to suture tissue within a narrow, confined space. In particular, described herein are suture passers having an elongate body and a lower jaw member that houses a tissue penetrator that is adapted to extend laterally from the lower jaw member and be deflected by a second jaw member? The second jaw member typically deflects the tissue penetrator either distally or proximally.

International Classification:

A61B 17/04

Abstract:

Devices for easily and quickly tying complex suture knots are disclosed. The knot tying accessories described herein provide a means for introducing a complex knot pattern into a bight of suture using a device body and a guide thread. The device body includes system for maintaining the guide thread and suture in a convoluted pathway, either with the use of channels, protrusions, or a combination of both within its interior, on its exterior, or both. The guide thread may include a coupler at one end for holding a suture end while the guide thread leads the suture through the convoluted path defined within the guide body. Pull tabs may also be included to aid with exchanging the guide thread for the suture ends.
