Appl. No.:

11/728010

Inventors:

Samuel Shaolian - Newport Beach CA, US
Shahram Moaddeb - Irvine CA, US
Maurice Buchbinder - La Jolla CA, US
David Zarbatany - Laguna Niguel CA, US
Jason Tran - Santa Ana CA, US

Assignee:

International Classification:

A61F 2/24
A61B 18/18

US Classification:

606041000, 623002370, 623002110

Abstract:

An activation device for applying energy to an implanted annuloplasty ring is described. In some embodiments, the activation device includes an outer elongate member having an outer elongate member distal end and an outer elongate member proximal end, and a lumen therebetween. In some embodiments, the activation device further includes an inner elongate member having a inner elongate member distal end and a inner elongate member proximal end, and a lumen therebetween, wherein the inner elongate member is slidably insertable through the lumen of the outer elongate member. In some embodiments, the activation device further includes at least one adjustable spline having spline proximal and spline distal ends, the spline distal end connected to the inner tubular member distal end and the spline proximal end connected to the outer tubular member distal end, wherein the adjustable spline is configured to flex as the inner tubular member distal end is drawn proximally toward the outer tubular member distal end while the inner elongate member resides in the lumen of the outer elongate member. In some embodiments, the activation device further includes at least one energy-transfer element coupled to the adjustable spline.

International Classification:

A61F 2/24

US Classification:

623002110, 623002370

Abstract:

An intraoperative adjustment device is described. In some embodiments, the device includes an elongate body including a proximal end and a distal end, the distal end configured to penetrate an outer surface of an adjustable cardiac implant implanted in a patient's heart, and the proximal end and the distal end connected by at least one energy-transfer member. In some embodiments, the distal end includes at least one electrode coupled to the energy-transfer member and configured to deliver an activation energy to the adjustable cardiac implant. In some embodiments, the proximal end is configured to attach to an energy source that provides the activation energy. In some embodiments, the proximal end is configured to be located outside the patient's body while the distal end is coupled to the adjustable cardiac implant that is implanted in the patient's heart.

International Classification:

A61F 2/24

US Classification:

623 237

Abstract:

An adjustable annuloplasty device is described. In some embodiments, the device includes a body member having a surface that conforms at least partially to a cardiac valve annulus. The body member comprises a shape-memory member that transforms from a first configuration to a second configuration in response to an applied energy. In some embodiments, the device further includes a first electrode assembly, coupled to the shape-memory member, that transfers energy to the shape-memory member, and a second electrode assembly, coupled to the shape-memory member, that transfers at least a portion of the energy away from the shape-memory member.

US Classification:

623 237

Abstract:

An adjustable implantable medical device and adjustment device are described. In some embodiments, the adjustment device includes a lead with a distal end modified to permit better engagement and securement to the described implantable devices. In some embodiments, the contact of the lead is bent. Some embodiments include a coil that engages and secures the lead to the implantable device. Some embodiments include a suture line to aid in securing the lead to the implantable device.
