Abstract
A mechanical suture fastener includes a crimpable sleeve defining a channel therein. The crimpable sleeve also has a sleeve length, a channel diameter, and a sleeve length to channel diameter ratio of at least 4.0. The mechanical suture fastener also includes a flange joined to the crimpable sleeve on a distal end of the sleeve. The flange further includes a distal opening which is in communication with a proximal opening defined by the crimpable sleeve. The mechanical suture fastener also includes an inner flange radius of at least 0.007 inches.
Claims16
A mechanical suture fastener that is configured to retain one or more portions of suture having an approximate size of 6-0, 7-0, or 8-0, the mechanical suture fastener comprising:
- a sleeve extending along a longitudinal axis from a proximal end to a distal end, the sleeve having an interior surface and an exterior surface, with the interior surface defining at least a portion of a channel that extends from the proximal end to the distal end of the sleeve, wherein a sleeve length is a distance from the proximal end of the sleeve to the distal end of the sleeve along the longitudinal axis, wherein the interior surface has a cylindrical shape such that the channel has a circular cross-sectional shape having a channel diameter, wherein a sleeve length to channel diameter ratio is about 4.69 to about 4.87;
- and
- a flange that is coupled to the distal end of the sleeve such that a portion of the flange defines a distal opening of the channel, wherein a proximal end of the interior surface of the sleeve defines a proximal opening of the channel that is in communication with the distal opening via the channel,
- wherein the channel is configured to receive the one or more portions of suture that is configured to extend through the channel from the proximal opening to the distal opening, and
- wherein the sleeve is configured to be deformed in a crimping operation performed on the exterior surface of the sleeve by a crimping mechanism of a crimping device, the sleeve being deformed in a direction normal to the longitudinal axis such that the one or more portions of suture extending through the channel are secured within the channel by one or more portions of the interior surface of the deformed sleeve following the crimping operation.
