Abstract

An adjustable annuloplasty device holder has a member having an anterior segment and a posterior segment that are shaped to hold an anterior portion and a posterior portion, respectively, of an annuloplasty device. The anterior segment has a given size and the posterior segment is adjustable in order to change the anterior-posterior ratio of the holder to accommodate annuloplasty devices having a plurality of different anterior-posterior ratios.

Claims

1. A method of using an adjustable annuloplasty holder device, the method comprising the steps of:

receiving an adjustable annuloplasty device holder possible of having a plurality of different anterior-posterior ratios as the inter-trigonal distance remains constant, the holder comprising a member having an anterior segment and a posterior segment that are shaped to hold an anterior portion and a posterior portion, respectively, of a first annuloplasty device having a first anterior-posterior ratio, wherein the anterior segment has a given size and the holder is adjustable by a component attachable to the member without changing the constant inter-trigonal distance in order to change the anterior-posterior ratio of the holder to accommodate annuloplasty devices having a plurality of different anterior-posterior ratios greater than the first anterior-posterior ratio, the member comprising an outer rim for holding the first annuloplasty device;

receiving an annuloplasty device of the given size of the anterior segment of the holder and of a given anterior-posterior ratio greater than the first anterior-posterior ratio;

adjusting the posterior segment of the holder such that the member has the given anterior-posterior ratio of the annuloplasty device; and

mounting the annuloplasty device to the holder.

2. The method of claim 1, further comprising the steps of:

delivering the annuloplasty device mounted on the holder to a heart valve annulus;

suturing the annuloplasty device to the heart valve annulus;

removing the annuloplasty device from the holder; and

withdrawing the holder.

3. The method of claim 1, wherein the component is one of a plurality of flanges extending radially from the posterior segment by varying distances in order to change the anterior-posterior ratio of the holder, and the adjusting step involves extending the flanges to provide the given anterior-posterior ratio.

4. The method of claim 3, wherein the plurality of radially extending flanges are slidably disposed within the member.

5. A method of using an adjustable annuloplasty holder device, the method comprising the steps of:

receiving an adjustable annuloplasty device holder possible of having a plurality of different anterior-posterior ratios as the inter-trigonal distance remains constant, the holder comprising a member having an anterior segment and a posterior segment that are shaped to hold an anterior portion and a posterior portion, respectively, of an annuloplasty device, wherein the anterior segment has a given size and the posterior segment is adjustable without changing the constant inter-trigonal distance in order to change the anterior-posterior ratio of the holder to accommodate annuloplasty devices having a plurality of different anterior-posterior ratios;

receiving an annuloplasty device of the given size of the anterior segment of the holder and of a given anterior-posterior ratio;

adjusting the posterior segment of the holder such that the member has the given anterior-posterior ratio of the annuloplasty device; and

mounting the annuloplasty device to the holder;

wherein the adjustable annuloplasty device holder further comprises a plurality of radially extending flanges in the posterior segment that are extendible varying distances in order to change the anterior-posterior ratio of the holder, and the adjusting step involves extending the flanges to provide the given anterior-posterior ratio; and

wherein the mounting step comprises mounting the annuloplasty device to the plurality of flanges.

6. A method of using an adjustable annuloplasty holder device, the method comprising the steps of:

receiving an adjustable annuloplasty device holder possible of having a plurality of different anterior-posterior ratios, the holder comprising a member having an anterior segment and a posterior segment that are shaped to hold an anterior portion and a posterior portion, respectively, of an annuloplasty device, wherein the anterior segment has a given size and the posterior segment is adjustable in order to change the anterior-posterior ratio of the holder to accommodate annuloplasty devices having a plurality of different anterior-posterior ratios;

receiving an annuloplasty device of the given size of the anterior segment of the holder and of a given anterior-posterior ratio;

adjusting the posterior segment of the holder such that the member has the given anterior-posterior ratio of the annuloplasty device; and

mounting the annuloplasty device to the holder,

wherein the adjustable annuloplasty device holder further comprises at least one detachable flange that is attachable to or detachable from the member in order to change the anterior-posterior ratio of the holder without changing the constant inter-trigonal distance, and the adjusting step comprises attaching or detaching the at least one flange.

7. The method of claim 6, wherein the at least one detachable flange is attachable to the member by a snap-fit connection.

8. The method of claim 6, wherein the holder comprises first and second detachable flanges, and the first detachable flange is attachable to the member and the second detachable flange is attachable to the first detachable flange.

9. The method of claim 8, wherein the first and second detachable flanges are attachable to the member and each other using snap-fit connections.
