Suture-fastening clip

摘要

A clip for securing suture to tissue includes a generally tubular body, with at least one bend area along the length of the generally tubular body and one or more tabs cut from the wall of the generally tubular body. The clip in the open configuration is generally straight along the length of the generally tubular body, and the tabs are in general alignment with the tab out wall. The tab in a closed configuration assumes a shape having at least one bend along its length, and the tabs are bent or otherwise positioned to extend into and at least partially obstruct the inner lumen. The clip can be formed from memory material such as nitinol, and the clip may be biased toward its closed configuration.

主权项

1. A clip for securing suture, the clip comprising:
a generally tubular body having a distal end, a proximal end, a length, an outer wall defining sides extending generally from the distal end to the proximal end, an inner lumen, a distal generally tubular portion, and a proximal generally tubular portion, and further comprising a first tab cut at least partially from the outer wall of the distal generally tubular portion of the generally tubular body, wherein the first tab comprises a first tab base at which the first tab is secured to the outer wall, the first tab further comprising a first tab free end, wherein the first tab base and the first tab free end are on opposing ends of the first tab and are longitudinally spaced away from each other along the length of the generally tubular body; wherein the clip has a first configuration wherein the generally tubular body is relatively straight along its length, and the clip has a second configuration where a bend is formed at a hinge point along the length of the generally tubular body, wherein the distal generally tubular portion extends distally of the hinge point and the proximal generally tubular portion extends proximally of the hinge point, wherein the first tab base is longitudinally spaced away from the hinge point along the length of the generally tubular body, wherein the first tab free end is placed longitudinally adjacent the hinge point with respect to the length of the generally tubular body, wherein the generally tubular body, including the inner lumen thereof, assumes a general V-shape when the clip is in the second configuration, and wherein when the clip is in the second configuration the clip is no longer straight and the entirety of the distal generally tubular portion is bent out of longitudinal alignment from the proximal generally tubular portion about the hinge point, the bend creating a crimped region within the inner lumen at the hinge point so as to at least partially obstruct the inner lumen, wherein when the clip is in the second configuration the first tab extends at least partially into the inner lumen and into the inner lumen at the hinge point and within the crimped region.
