ABSORBABLE ANCHOR FOR HERNIA MESH FIXATION
First Claim
Patent Images
1. An anchor for penetrating mesh and tissue and for fixing the mesh to the tissue, the anchor comprising:
- a threaded head section defines an outer periphery having a helical thread formed thereon and a pair of notches formed therein, wherein the pair of notches extend an entire length of the head section in a direction parallel to a longitudinal axis of the anchor, the anchor being configured to be independently driven by a rotatable actuator engaging the pair of notches formed in the head section; and
a distal non-cannulated tissue snaring section being tapered and having a helical thread on at least a distal portion thereof, wherein a distal tip of the helical thread includes a tapering defining an angled blade configured to penetrate the mesh.

Abstract
A method of forming and deploying an improved absorbable anchor for hernia mesh fixation is disclosed. The absorbable anchor of the present invention functions to securely fasten tough, non macro-porous, and relative inelastic mesh to soft tissue. The anchor is formed from co-polymers of lactide and glycolide.

12. An anchor for penetrating mesh and tissue and for fixing the mesh to the tissue, the anchor comprising:
-
a threaded head section having a proximal end, a distal end and a periphery, the periphery having a helical thread projecting radially outward thereform and a pair of diametrically opposed notches formed therein, wherein the anchor is configured to be independently driven by a rotatable actuator having a pair of elongate drivers that are configured to extend through the pair of diametrically opposed notches; and a distal non-cannulated tissue snaring section being tapered and having a helical thread on at least a distal portion thereof, the distal end of the helical thread tapering inwards to form an angled blade - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)

22. An anchor for penetrating mesh and tissue and for fixing the mesh to the tissue, the anchor comprising:
-
a head section having a proximal end, a distal end and an edge, the edge having a helical thread projecting radially therefrom, the head section having notches formed therein and extending from the distal end to the proximal end thereof, a non-cannulated body section connected to and extending from the distal end of the head section, the body section including a threaded portion and a retention portion, the threaded portion being tapered and having a helical thread projecting radially therefrom, and the retention portion located between the threaded portion and the head, the retention portion having a diameter less a proximal-most thread of the helical thread of the threaded portion, wherein the retention portion inhibits longitudinal movement of a surgical mesh located therein; and a distal tip at a distal end of the threaded portion of the body section, wherein the helical thread of the threaded portion of the body section tapers inwardly towards the distal tip. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31)
