Abstract
Disclosed are devices and methods for deploying securement devices onto sutures with precise and consistent tension levels in the sutures. Devices can include a handle portion having a trigger and a suture tensioning mechanism, and a shaft portion extending distally from the handle portion with at least one suture securement device positioned at a distal end portion of the shaft portion. The device can receive a suture or sutures extending through the suture securement device, across the trigger, and to the suture tensioning mechanism. Actuation of the suture tensioning mechanism gradually increases tension in the received suture until the trigger is actuated by pressure from the suture when a predetermined amount of tension is reached in the suture. Actuation of the trigger can cause the suture securement device to be deployed from the shaft portion onto the received suture with the predetermined amount of tension in the suture.
Core Innovation
The device deploys suture securement devices onto sutures and comprises a handle portion with a trigger and a suture tensioning mechanism, a shaft portion extending distally from the handle portion, and at least one suture securement device positioned at a distal end portion of the shaft portion. A received suture extends through the securement device, around a peg, across the trigger, and to the tensioning mechanism. Actuation of the tensioning mechanism adjusts tension in the received suture.
When the received suture reaches a predetermined amount of tension, the suture actuates the trigger, causing the suture securement device to deploy from the shaft portion onto the suture. Device configurations include multiple-firing clip or crimp systems with sequential securement loading, cutting, and optional force sensing, adjustable tension thresholds, or motorized tensioning. The shaft portion places securement devices on sutures around an annular structure using motor-, gear-, and conveyor-driven components.
Claims Coverage
The claims identify one independent claim comprising three inventive features directed to tensioning a received suture and deploying a suture securement device.
Handle and shaft arrangement
A handle portion includes a trigger and a suture tensioning mechanism, a shaft portion extends distally from the handle portion, and at least one suture securement device is positioned at a distal end portion of the shaft portion.
Suture routing across peg and trigger
The apparatus receives a suture extending through the suture securement device, around a peg positioned on a first side of the trigger, across the trigger, and to the suture tensioning mechanism positioned on a second side of the trigger opposite the peg.
Trigger-actuated deployment at predetermined tension
Actuation of the suture tensioning mechanism adjusts tension in the received suture, and when a predetermined amount of tension is reached in the suture, the suture actuates the trigger, causing the suture securement device to deploy from the shaft portion onto the received suture.
The independent claim covers an apparatus combining a shaft-mounted securement device, a defined suture routing around a peg and across a trigger, and trigger-actuated deployment responsive to reaching a predetermined suture tension.
Stated Advantages
The system provides more consistent suture tension.
The system reduces risks associated with excess slack or tension.
Documented Applications
Deploying suture securement devices onto sutures, including use in multiple-firing clip or crimp systems configured to adjust tension in a received suture.
Placing suture securement devices on sutures around an annular structure or at a suture loop around tissue.
