Problems solved by technology

The potential health risks posed by this dilemma have not been adequately addressed by current technology in this space, and it is difficult to envisage anchoring techniques that will maintain the depth of deployment required to consistently secure the prosthesis without risking damage to nearby cardiac features
[0016] The foregoing examples are intended to highlight the long-standing inability of the long-standing aortic valve replacement technique to be effectively used as an endocardiac surgical alternative

Embodiment Construction

[0104] As set forth in more detail below, exemplary embodiments of the present invention allow the efficient and reliable deployment of specially designed TCAT anchors for securing a prosthesis to the heart of a human by means of a proprietary catheter-based delivery mechanism. organize.

[0105] figure 1 A heart valve replacement prosthesis 1 is illustrated having a ring 10 which, in an exemplary embodiment, may be elastic. figure 1 An applicator 20 having an applicator shaft 21 and a resilient arm 22 is also illustrated. A resilient arm 22 may be fixed to the distal end of the applicator shaft 21 and may connect the distal end of the applicator shaft 21 to the ring 10 of the replacement prosthesis 1 . figure 1 Also illustrated is a driver 40 as will be described in more detail below.

[0106] As will generally be understood, for example, as described in U.S. Patent No. 7,621,948, the entire content of which is incorporated herein by reference, as fully disclosed herein, t...

Abstract

Systems and methods recited herein provide for affixation of a prosthetic valve to surrounding tissue, by at least one anchor and an anchor deployment device. The prosthetic valve device may be compliant with native tissue and may receive the at least one anchor in at least one anchor receptacle to affix the prosthetic valve to native tissue. The anchor may include a distal tip, a proximal head, and a tension component, such that upon deployment into tissue the tension component is situated in a tensioned state to exert a pulling force on the distal end of the anchor.
