Embodiment Construction

[0021] The present disclosure generally relates to a crimping tool and associated method for reducing the size of a component, eg, reducing the diameter of a component from a first diameter to a reduced second diameter. One use of the crimping tool is for crimping a radially compressible stent or stented heart valve for deployment in a patient. However, the crimping tool can be used to reduce the size of various other types of compressible elements, as will be appreciated by those of ordinary skill in the art. Accordingly, the following disclosure focuses on reducing the size of radially compressible stents for illustrative purposes only, and is not limiting.

[0022] In operation, the crimping tool is configured to apply a radial compressive force to the stent to reduce the size of the stent. In one embodiment, the crimping tool is operable to compress the scaffold to approximately 50% of its original size. However, the crimping tool may be configured to compress the stent ...

Abstract

The present application provides a crimping tool for crimping a stented heart valve, comprising: a housing having a front wall and a back wall; a compression assembly disposed between the front wall and the back wall and comprising a stent-receiving chamber for receiving the stented heart valve; and a delivery device holder slidably coupled to the front wall of the housing. The compression assembly is movable between an uncollapsed position and a collapsed position to reduce the diameter of the stented heart valve.

Part 119(e)(1)) ; U.S. Provisional Patent Application No. 61 / 287,030, filed December 16, 2009; and priority to U.S. Provisional Patent Application No. 61 / 322,480, filed April 9, 2010; the entire teachings of each Provisional Patent Application are incorporated by reference way combined here. technical field [0003] The present disclosure generally relates to tools for reducing the diameter of components. More specifically, the present disclosure relates to a crimping tool and method for radially compressing a stent from a first diameter to a reduced second diameter. Background technique [0004] When a patient's heart valve is diseased or damaged, the heart valve needs to be replaced. Surgical insertion of heart valve prostheses has extended the average lifespan of many patients with d...
