Annuloplasty ring and holder combination
First Claim
1. An annuloplasty ring and holder assembly combination, comprising:
- an annuloplasty ring having a continuous periphery with an elongated generally oval-shape in plan view defining a major axis and a corresponding major axis dimension across a widest span, and a minor axis perpendicular to the major axis and across the middle of the annuloplasty ring, and a corresponding minor axis dimension, the major axis dimension being substantially longer than the minor axis dimension; and
a ring holder, comprising;
an upstanding post having an attachment assembly to which a handle can be removably secured;
a lower template portion secured to the post and including first and second narrow arms extending outward in generally opposite directions from the post and terminating in first and second ring securing segments having suture holes, each of the ring securing segments having an arcuate shape oriented to be convex outward and being narrow in a radial direction so as to form a T-shape with the associated narrow arm, and wherein the ring securing segments are spaced apart a distance approximately equal to the major axis dimension so that the ring securing segments each engage and conform to an inner edge of the annuloplasty ring, wherein the narrow arms and narrow arcuate ring securing segments leave open a large portion of the area enclosed by the annuloplasty ring thus enhancing visibility therethrough; and
restraining sutures between the ring securing segments and the arcuate sides of the annuloplasty ring releasably securing the ring holder to the annuloplasty ring.

Abstract
An annuloplasty ring holder includes an angled post for improved visibility and access by the surgeon. The post may be configured to be adjusted in angle and rotation. The ring holder can include a relatively open lower template, including relatively narrow extending radial arms with short, generally arcuate ring-retaining distal portions. The invention includes placements of suture holes and cutting wells which, in combination with improved suture routing, afford the user improved access to cutting the suture that is used to retain the annuloplasty ring to the holder. Another annuloplasty ring and ring holder combination disclosed includes a generally triangular-shaped ring and a generally T-shaped holder. The ring holder has a base portion forming the top of the T shape and engaging against a first segment of the ring, with a radial arm extending from the base portion and forming the post of the T. The radial arm engages against a junction between two segments of the ring.

12. An annuloplasty ring and holder assembly combination, comprising:
-
an annuloplasty ring having a continuous periphery with an elongated generally oval-shape in plan view defining a major axis and a corresponding major axis dimension across a widest span, and a minor axis perpendicular to the major axis and across the middle of the annuloplasty ring, and a corresponding minor axis dimension, the major axis dimension being at least twice as long as the minor axis dimension; and a ring holder, comprising; an upstanding post having an attachment assembly to which a handle can be removably secured; a lower template portion secured to the post and including first and second arms extending outward in generally opposite directions from the post and terminating in first and second securing segments spaced apart a distance approximately equal to the major axis dimension so that the securing segments each engage an inner edge of the annuloplasty ring, each securing segment defining at least one suture cutting well therein; at least one restraining suture between each securing segment and the engaged portion of the annuloplasty ring that extends over the cutting well in the corresponding securing segment to releasably secure the ring holder to the annuloplasty ring, wherein there are no other restraining sutures than those that secure the securing segments to the annuloplasty ring. - View Dependent Claims (13, 14, 15, 16, 17)
