SYSTEMS, DEVICES, AND METHODS FOR EXTRUDING A SUTURE CORE

摘要

Systems, devices, and methods for cutting a filament or suture having an extrudable inner core member are provided. In one exemplary embodiment, a device includes a compression element to compress an inner core away from a knot disposed at a distal end of the suture, and a cutting element disposed within a portion of the compression element to cut the inner core after it has been compressed. As a result, an amount of extrudable inner core that extends distally beyond the knot is minimized without negatively impacting the integrity of the knot. In other embodiments, the compression and cutting elements are separately provided as two different devices. The actions of compressing and cutting can be performed using a variety of techniques, including those known to those skilled in the art. Methods for clamping the inner core and then cutting a portion of the inner core are also provided.

主权项

1. A device for cutting a suture having an extrudable core, comprising:
a compression element having a first jaw and a second jaw pivotally coupled thereto, the first and second jaws being configured to engage therebetween a suture having an extrudable core, the jaws being configured to close to compress the extrudable core away from a knot associated with the suture; a cutting element configured to pass through the first jaw to cut a suture having an extrudable core that is disposed between the first and second jaws after the jaws have been closed; and a handle assembly operable to first actuate the compression element to close the jaws and subsequently to actuate the cutting element to cut a suture having an extrudable core that is disposed between the closed first and second jaws.
