Abstract: A positioning device for maintaining positioning of an introducer hub relative to a repositioning sheath or catheter may be provided. The positioning devices may include a first coupler, a second coupler configured to be removably coupled to a portion of a repositioning sheath or catheter that is proximal to the first coupler, and a portion extending between the first coupler and the second coupler, the extension bridge configured to maintain a fixed axial distance between the introducer hub and a proximal end of the repositioning sheath or catheter. A flexible hinge may be incorporated, where a medical device would be configured to pass through the second coupler, the flexible hinge, and the first coupler.

Abstract: A biocompatible, biodegradable surgical fastening device employs opposed engagement surfaces having receptacles and protrusions, in which the receptacles are responsive to the protrusions on the opposed engagement surface. The fastening device has a generally planar construction defining the engagement surface, such that each engagement surface has a proximate end for engaging the opposed engagement surface, and a distal end for attachment to an anatomical structure. The distal end of two devices each connect to anatomical structures to be joined, and the engagement surfaces joined to each other at the proximate end to complete the repair. The distal end of the engagement surface defines a flexible attachment portion having a lateral attachment width, the lateral width configured for securement to the anatomical structure across a nonlinear disposition of the lateral width. The flexible lateral width conforms around an irregular shape of an anatomical structure such as a tendon, ligament or bone.
