A chamber assembly for testing a valve includes a proximal chamber portion that defines a proximal interior space, and a distal chamber portion that defines a distal interior space. The distal interior space includes a gas space. When a liquid is inserted into the proximal and distal chambers there is an interface between the liquid and a gas in the gas space. A valve holder is disposed adjacent to the proximal interior space and the distal interior space. The valve holder is configured to receive the valve in a bore of the valve holder. A shortest distance between a center of the valve when in the bore and the interface is at least about 45 mm.

Systems for testing valves

This document provides systems and methods for testing of various kinds of valves. For example, this document provides systems and methods for accelerated life testing of prosthetic heart valves.

System for testing valves

A conditioning system includes a sample chamber capable of receiving a specimen as well as first and second specimen-holding fixtures positioned within the sample chamber and configured to apply mechanical stimulation to a specimen held by the fixtures. The system has at least one port capable of providing a fluid to the sample chamber. The chamber is sized and shaped so that it can be inserted into an imaging device which can record images of a specimen held by the fixtures.
