Percutaneous delivery systems for anchoring an implant in a cardiac valve annulus

A system for delivering and anchoring an implant to a valve annulus, the system comprising:

• a template catheter configured to deliver a subannular anchor to a valve annulus of a heart of a patient, wherein the template catheter comprises a cylindrical tube having a circumference and a template extending from the cylindrical tube, wherein the template comprises a first template portion disposed between the cylindrical tube and a first end of the template and a second template portion disposed between the cylindrical tube and a second end of the template, wherein the first end of the template includes an enclosed anchor guide, wherein the second end of the template includes a partially enclosed anchor guide, wherein the template is asymmetrical to reduce the diameter of the template when the template is collapsed, wherein both the first end of the template and the second end of the template are configured to curve and fit within a profile of the cylindrical tube when the template is collapsed, and the second end of the template is proximal to the first end of the template when the template is collapsed;
• and
• an implant configured to be delivered to the valve annulus, wherein the implant includes a first anchoring portion aligned with the enclosed anchor guide.
