Active holder for annuloplasty ring delivery
First Claim
1. A holder for delivering an annuloplasty ring, comprising:
- a template having a peripheral edge sized to receive an annuloplasty ring;
a plurality of sutures attaching the annuloplasty ring to the template;
a handle having a pivot on which the template pivots to a variety of angles with respect to the handle;
a ring detachment mechanism for detaching the sutures attaching the annuloplasty ring to the template, the ring detachment mechanism being remotely actuated from the handle and including a release pin movable in a bore in the template between an extended position around which the plurality of sutures loop to attach the annuloplasty ring to the template and a retracted position that frees the suture loops to detach the annuloplasty ring from the template; and
a pivoting mechanism in the handle for pivoting the template.

Abstract
An active annuloplasty ring holder having a template that can be folded or pivoted to the side allowing the template to align longitudinally with the handle and enter the patient'"'"'s chest through a small incision. The holder may include a mechanism to remotely detach sutures fastening the ring to the holder, thereby detaching the ring while avoiding the risk associated with introducing a scalpel into the operating field. A detachment mechanism may include a movable pin actuated by a pull wire that releases a plurality of holding sutures, or a hot wire, knives, or pull wire that severs the sutures. The holder may have a built-in light source for better visualization of the ring inside the heart. The holder may also have an optical means of visualizing the inside of the heart from the proximal end of the handle.
