Filed:

Apr 29, 2004

Appl. No.:

10/834556

Inventors:

Patrick M. McCarthy - Chicago IL, US

Assignee:

Edwards Lifesciences Corporation - Irvine CA

International Classification:

A61F 2/24

US Classification:

623 236, 623 241, 623 238

Abstract:

A mitral annuloplasty ring that has an outward and an upward posterior bow. The ring defines a closed, modified oval shape with a minor-major axis dimension ratio of between about 3. 3:4 to 4:4. The ring is made of a material that will substantially resist distortion when subjected to the stress imparted thereon when the ring is implanted in the mitral valve annulus of an operating human heart. As a result, the annuloplasty ring corrects for pathologies associated with mitral valve prolapse, or Barlow's syndrome, in which the leaflets tend to be elongated or floppy.

International Classification:

A61F 2/24

US Classification:

623 236

Abstract:

An annuloplasty ring having a three-dimensional discontinuous form generally arranged about an axis with two free ends that are axially offset. The ring is particularly suited for repair of the tricuspid valve, and more closely conforms to the annulus shape. The ring is more flexible in bending about radially extending axes than about the central axis. The ring may have an inner structural support covered by a pliable sleeve and/or a fabric tube. The structural support may have a varying cross-section, such as a C-shaped cross-section in a mid-section between two free ends and a rectangular cross-section at the free ends. A deliver template having a mounting ring with about the same shape as the ring facilitates implant, and may be releasably attached to a delivery handle. The deliver template may include a plurality of cutting guides for releasably attaching the annuloplasty ring thereto while presenting maximum outer surface area of the ring. The template may have an outwardly-facing groove to receive and retain the ring.

International Classification:

US Classification:

623 236, 623 237

Abstract:

A mitral heart valve annuloplasty ring having a posterior bow that conforms to an abnormal posterior aspect of the mitral annulus. The ring may be generally oval having a major axis and a minor axis, wherein the posterior bow may be centered along the minor axis or offset in a posterior section. The ring may be substantially planar, or may include upward bows on either side of the posterior bow. The ring may include a ring body surrounded by a suture-permeable fabric sheath formed of a plurality of concentric ring elements or bands. The posterior bow is stiff enough to withstand deformation once implanted and subjected to normal physiologic stresses. A method of repairing an abnormal mitral heart valve annulus having a depressed posterior aspect includes providing a ring with a posterior bow and implanting the ring to support the annulus without unduly stressing the attachment sutures.

International Classification:

A61B 1/32

US Classification:

600232

Abstract:

A surgical retractor includes a pair of parallel arms that are mounted to a toothed crossbar. One of the arms is fixed to one end of the crossbar, while the other arm is movable along the crossbar by means of a pinion. One or both of the arms includes on its upper surface a bar having a longitudinally extending flat surface. A rod is connected to the bar by means of a bracket. The bracket can be locked in position relative to the bar by a first set screw that engages the flat surface. A rod extends through an opening in the bracket and is retained in place there by a second set screw. The rod includes a circumferentially extending shoulder that engages the bracket so as to locate the rod in a desired position. One or more flat surfaces are formed on the rod adjacent the shoulder for engagement by the second set screw. One of the flat surfaces causes the rod to be positioned precisely as necessary to perform a surgical procedure, while the other of the flat surfaces enables the rod to be moved to an out-of-the way position and locked in place there.

International Classification:

A61F 2/24

US Classification:

623 236

Abstract:

A remodeling mitral annuloplasty ring with a reduced anterior-to-posterior dimension to restore coaptation between the mitral leaflets in mitral valve insufficiency (IMVI). The ring has a generally oval shaped body with a major axis perpendicular to a minor axis, both perpendicular to a blood flow axis. An anterior section lies between anteriolateral and posteriomedial trigones, while a posterior section defines the remaining ring body and is divided into P, P, and P segments corresponding to the three scallops of the same nomenclature in the posterior leaflet of the mitral valve. The anterior-to-posterior dimension of the ring body is reduced from conventional rings; such as by providing, in atrial plan view, a pulled-in P segment. Viewed another way, the convexity of the P segment is less pronounced than the convexity of the P segment. In addition, the ring body may have a downwardly deflected portion in the posterior section, preferably within the P and P segments.

A mitral annuloplasty ring that has an outward and an upward posterior bow. The ring defines a closed, modified oval shape with a minor-major axis dimension ratio of between about 3. 3:4 to 4:4. The ring is made of a material that will substantially resist distortion when subjected to the stress imparted thereon after implantation in the mitral valve annulus of an operating human heart. The outward and upward posterior bow of the annuloplasty ring corrects for pathologies associated with mitral valve prolapse, as seen with Barlow's syndrome for instance, in which the leaflets tend to be elongated or floppy. Desirably, the outward bow includes a more pronounced outward bulge having an angular extent that approximately equals the angular extent of the upward bow. Sections adjacent the outward bulge may be relatively straight.

Abstract:

An apparatus for implantation in an annulus of a tricuspid valve. The apparatus has an anterior annulus aspect, a posterior annulus aspect, and an atrioventricular (AV) node located adjacent the anterior annulus aspect. The apparatus includes an ovoid main body portion. The main body portion has an anterior body segment adapted for placement adjacent the anterior annulus aspect, a posterior body segment located opposite the anterior body portion and adapted for placement adjacent the posterior annulus aspect, and oppositely disposed left and right side body segments extending between the anterior and posterior body segments. At least two valve leaflets are secured within the main body portion and are coaptable to permit unidirectional flow of blood. A cushioned section is attached to the main body portion, coextends with a portion of the main body portion, and is adapted for placement adjacent the AV node.
