SEPTAL PERFORATION PROSTHESIS

摘要

The vast majority of septal perforations are plugged by providing a septal perforation prosthesis in a limited number of flange sizes and shapes, stem sizes and stem lengths. Insertion of the prosthesis is simple and positive, and does not require, for example, folding or wadding up one flange and pulling the thus-folded or -wadded up flange through the perforation. Likewise, removal of the prosthesis does not require the occasionally traumatic pulling of a flange through the perforation.

主权项

1. A prosthesis for closing a septal perforation comprising two flanges, each provided with a raised region, each raised region provided with a magnet, the magnets of the two flanges oriented so that they attract each other when the flanges are properly oriented, the raised regions cooperating in the assembled prosthesis to provide a stem which resides in the perforation, the stem having a cross-sectional configuration transverse to an axis of the stem which is one of circular and oval.
