Abstract
Abstract The present invention provides an instrument and method for surgical extraction. In one example, a surgical instrument for extracting a prosthetic device includes a distal portion transitionable from an insertion configuration to an extraction configuration, wherein the insertion configuration is adapted for displacement along a portion of a prosthetic device, and the extraction configuration is adapted for engaging and extracting the prosthetic device, and a proximal portion connected to the distal portion. In another example, an instrument for surgical extraction includes at least one extraction prong wherein the at least one extraction prong comprises a transverse flange, and a mounting portion wherein the at least one extraction prong is secured to the mounting portion.
