Tissue prosthesis processing technology
First Claim
1. A medical prosthesis catheter loading apparatus, comprising:
- a. a crimping assembly for reducing the diameter of a prosthesis, the crimping assembly comprises a base, a crimp head connectable to the base, and an actuation mechanism connected to the base and connectable to the crimp head to actuate the crimp head, wherein the base comprises a pair of crimp head retaining members, the retaining members being constructed of a sterilizable material, crimp elements, and having a crimp head element guide with at least two concentric arrangements of linear grooves; and
b. a catheter clamp for holding a catheter adjacent to the prosthesis.

Abstract
A heart valve prostheses crimping apparatus and method for deducing the diameter of stents containing heart valve prosthesis. A medical prosthesis catheter loading apparatus, including a crimping assembly for reducing the diameter of a prosthesis; and a catheter clamp for holding a catheter adjacent to the prosthesis. Also disclosed is an apparatus for reducing the diameter of a medical prosthesis, including a base, a crimp head connectable to the base, and an actuation mechanism connected to the base and connectable to the crimp head to actuate the crimp head. Also disclosed is a method of loading a medical prosthesis into a catheter, including the steps of reducing the diameter of a prosthesis from its normal deployed state to a diameter less than that of the lumen of the catheter; holding a catheter adjacent to the reduced diameter prosthesis; and moving the prosthesis into the catheter lumen.
