Ventricular pump coupling

摘要

A device and method for creating a connection with the left ventricle of a heart are provided. A seal member capable of moving between a folded position and an open position is attached to the end of a conduit. An introducer capable of moving between a first and second position allows for the expansion of the seal member into an open position. A clamp component is positioned outside of the heart to provide an axial clamping force with the wall of the heart so that a seal is created between the seal member and the wall of the heart.

主权项

1. A device for creating a sealed connection between an end of a conduit and an opening in a wall of a heart, comprising:
a sleeve having a first end and second end, the end of the conduit being insertable into the first end of the sleeve and a surface of the conduit sealing with a surface of the sleeve; a seal member attached to the first end of the sleeve and capable of moving between a folded position and an open position to expand the seal member so that the seal member has a cross-dimension that is larger than a cross-dimension of the opening in the wall of the heart, the seal member including a first section extending from the sleeve towards a center line of the sleeve and being rotated away from the center line upon further insertion of the conduit into the sleeve, a second section extending from the first section away from the center line and rotating with the first section away from the center line upon insertion of the conduit into the sleeve, and a clamping piece extending distally on the second section when in the folded position and rotating therewith away from the center line and into contact with the wall of the heart upon insertion of the conduit into the sleeve; and a clamp component to be positioned outside of the heart, the clamping piece of the seal member and the clamp component being movable relative to one another to produce an axial clamping force with the wall of the heart between the clamp component and the seal member so that a seal is created between the seal member and the wall of the heart.
