Minimally-invasive annuloplasty repair segment delivery template and system
First Claim
1. A combination annuloplasty repair segment and holder, comprising:
- a holder including a template defining a distal end of the holder, the template being convertible from a generally linear shape to a curved shape that at least partly conforms to a corrected shape of an interior wall of a target annulus, wherein the template is biased toward the changed shape; and
an annuloplasty repair segment attached to the template and convertible between the linear shape and the curved shape of the template.

Abstract
An annuloplasty repair segment and template for heart valve annulus repair. The elongate flexible template may form a distal part of a holder that also has a proximal handle. Alternatively, the template may be releasably attached to a mandrel that slides within a delivery sheath, the template being released from the end of the sheath to enable manipulation by a surgeon. A tether connecting the template and mandrel may also be provided. The template may be elastic, temperature responsive, or multiple linked segments. The template may be aligned with the handle and form a two- or three-dimensional curve out of alignment with the handle such that the annuloplasty repair segment attached thereto conforms to the curve. The template may be actively or passively converted between its straight and curved positions. The combined holder and ring is especially suited for minimally-invasive surgeries in which the combination is delivered to an implantation site through a small access incision with or without a cannula, or through a catheter passed though the patient'"'"'s vasculature.
