Simulated environment for transcatheter heart valve repair

摘要

An apparatus for applying liquid pressure to resected tissue may include a fixture, a papillary assembly coupled to the fixture and having first and second spaced apart papillary attachment elements, and a resected mitral valve attached to the fixture. The fixture may have a first chamber, a second chamber, and an internal panel extending between the first and second chambers. The resected mitral valve may be attached to the internal panel and may have a posterior leaflet, an anterior leaflet, and tendinae chordae. The tendinae chordae may each be attached at a first end to the posterior leaflet or the anterior leaflet and at a second end to one of the papillary attachment elements. A first group of the tendinae chordae may be attached to the first papillary attachment element, and a second group of the tendinae chordae may be attached to the second papillary attachment element.

1. A simulation apparatus for mounting resected tissue, the apparatus comprising:
a fixture having a first chamber, a second chamber, and an internal panel extending between the first and second chambers, the fixture having at least one introducer configured to receive an elongated catheter assembly therethrough; a papillary assembly coupled to the fixture and having first and second spaced apart papillary attachment elements, each papillary attachment element being movable relative to the internal panel in at least one degree of freedom; and a resected mitral valve attached to the internal panel and having a posterior leaflet, an anterior leaflet, and tendinae chordae, the tendinae chordae each attached at a first end to the posterior leaflet or the anterior leaflet and at a second end to one of the papillary attachment elements, wherein a first group of the tendinae chordae are attached to the first papillary attachment element, and a second group of the tendinae chordae are attached to the second papillary attachment element.
