Anchor tip orientation device and method

摘要

A surgical device for inserting an anchor, including a handle having an actuator, an outer barrel shaft extending from the handle to a distal end and having a channel therethrough, and an outer barrel tip the distal end thereof having an elastomeric septum, a drive pin within the channel, and an implantable anchor removably coupled to the drive pin. The outer barrel shaft is coupled to an actuator for movement between a first extended position wherein the outer barrel shaft tip substantially cover the anchor, and a second retracted position where the outer barrel shaft tip do not cover the anchor. When the shaft is in the first position, the elastomeric septum of the outer barrel tip circumferentially surrounds and engages the anchor to thereby stabilize the anchor prior to deployment, and when the shaft is in the second position, the elastomeric septum does not engage the anchor.

1. A surgical device for inserting an implantable anchor, comprising:
a handle including an actuator; an outer barrel shaft extending outwardly from the handle to a distal end and having a channel extending therethrough; a outer barrel tip positioned at the distal end of the outer barrel shaft and having an elastomeric septum therein at a location proximal from the distal end of the outer barrel tip; a drive pin longitudinally aligned with and positioned within the outer barrel shaft channel; an implantable anchor having a tissue penetrating distal end, having a longitudinal axis, having a proximal end the entire surface of which extends at an angle of less than ninety degrees relative to the longitudinal axis, having lateral sides extending between said distal and proximal ends, and having an axial bore extending therein from the proximal end along said longitudinal axis, the axial bore being sized and shaped to receive therein a distal end of said drive pin to thereby removably coupled the drive pin and implantable anchor, and a filamentary element coupled to and extending laterally outward to an exterior of said anchor from a lateral side of the anchor at a location distal of the axial bore;wherein the outer barrel shaft is coupled to the actuator for movement between a first extended position wherein the outer barrel shaft and outer barrel tip substantially cover the anchor, and a second retracted position where the outer barrel shaft and outer barrel tip do not cover the anchor, and wherein when the shaft is in the first position, the elastomeric septum of the outer barrel tip circumferentially surrounds and engages the anchor to thereby stabilize the anchor prior to deployment, and wherein when the shaft is in the second position, the elastomeric septum does not engage the anchor.
