Publication number: 20220370097Abstract: A system for reshaping a valve annulus includes an elongate template having a length along a longitudinal axis and at least one concavity in a generally lateral direction along said length. The pre-shaped template is positioned against at least a region of an inner peripheral wall of the valve annulus, and at least one anchor on the template is advanced into a lateral wall of the valve annulus to reposition at least one segment of the region of the inner peripheral wall of the valve annulus into said concavity. In this way, a peripheral length of the valve annulus can be foreshortened and/or reshaped to improve coaptation of the valve leaflets and/or to eliminate or decrease regurgitation of a valve.Type: ApplicationFiled: January 4, 2022Publication date: November 24, 2022Applicant: Elixir Medical CorporationInventors: MOTASIM SIRHAN, JOHN YAN, VINAYAK BHAT, JOSEPH PARASCHAC, BENJAMYN SERNA

Publication number: 20220183843Abstract: A catheter system for delivering an anchor to a valve annulus in a heart valve includes a locating catheter and an anchor delivery catheter. The locating catheter has a distal end which can be advanced beneath the valve annulus near a target site on an upper surface of the valve annulus. The anchor delivery catheter has a distal end which can be advanced over the valve annulus to deliver an anchor along a delivery path to the target site. The distal end of the locating catheter has at least one magnetic element, and the distal end of the anchor delivery catheter has at least one magnetic element which attracts the at least one magnetic element on the locating catheter to pivotally couple the distal end of the anchor delivery catheter to the distal end of the locating catheter. In this way, the deliver catheter can be pivoted relative to the locating catheter to orient the delivery path away from the locating catheter.Type: ApplicationFiled: March 2, 2022Publication date: June 16, 2022Applicant: Elixir Medical CorporationInventors: Motasim SIRHAN, John YAN, Vinayak BHAT, Joseph PARASCHAC, Benjamyn SERNA
