Embodiment Construction

[0036] refer to figure 1 , shows an embodiment of the implant connector or ventricular connector 50 of the present invention, wherein the implant connector enables effective, secure and safe attachment of implant devices such as heart pumps to the heart.

[0037] In one embodiment, implant connector 50 includes a substantially circular frame 52 , a first member or ring 54 and a second member or ring 56 . The frame 52 includes a first planar member or wall 62 disposed transverse to a second planar member or flange 64 and extending generally upwardly or away from the second planar member. The first planar member 62 is generally circular in shape and its diameter is determined according to the diameter of the inflow conduit connected to the heart pump. It will be appreciated that the size and shape of the first planar member will vary based on the size and shape of the inflow conduit and heart pump. In this regard, the first planar member or wall 62 may be of any suitable size ...

Abstract

A connector for connecting an implant device to tissue of a person's body. The connector including a frame having first and second arms. The first and second arms define an opening, where at least a portion of the implant device is inserted through the opening. After insertion, an additional securing member is connected to the frame. The securing member is adapted to receive at least one suture to secure the frame to the tissue. The connector includes an adjuster that is movably connected to the first and second arms, where the adjuster is operable to cause the first and second arms to move toward each other and engage the implant device.

Description

Background technique [0001] Thousands of heart patients suffering from severe ventricular heart failure could benefit from a heart transplant. However, due to the lack of donated hearts, most patients face a shortened lifespan manifested by frequent hospitalizations, severe disability, and death due to congestive failure or cardiogenic shock. [0002] One medical device developed to help these heart patients is a heart pump, such as a ventricular assist device ("VAD"), which enables heart patients to prolong and sustain life. A heart pump is typically connected to the left ventricle of the heart. One end of a catheter, such as a graft, is connected to the heart pump and the other end is connected to the ascending or descending aorta. Once connected, the heart pump improves blood circulation by drawing blood from the left ventricle to the ascending or descending aorta. [0003] Traditional methods of heart pump implantation utilize a connector known as a sewing ring that is ...
