Cardiac treatment system and method

摘要

Devices and methods for providing localized pressure to a region of a patient's heart to improve heart functioning, including: (a) a jacket made of a flexible biocompatible material, the jacket having an open top end that is received around the heart and a bottom portion that is received around the apex of the heart; and (b) at least one inflatable bladder disposed on an interior surface of the jacket, the inflatable bladder having an inelastic outer surface positioned adjacent to the jacket and an elastic inner surface such that inflation of the bladder causes the bladder to deform substantially inwardly to exert localized pressure against a region of the heart.

主权项

1. A delivery system for delivering an implantable cardiac device, the delivery system comprising:
an elongate barrel; a plurality of elongate members configured to extend along a length of the elongate barrel and extend distally from the elongate barrel, and being advanceable distally with respect to the elongate barrel, each of the elongate members comprising a distal end for attachment to a cardiac implant configured to be implanted around an exterior of a heart, a control mechanism configured to extend and retract the plurality of elongate members relative to the elongate barrel; and a handle assembly attached to a proximal end of the elongate barrel, the handle assembly comprising a locking mechanism for releasably locking the control mechanism to the handle assembly in a position that holds the plurality of elongate members in a retracted position relative to the elongate barrel and a pistol grip configured to be held by a first hand of an operator while the operator uses a second hand to operate the control mechanism for the extension and retraction of the plurality of elongate members, the locking mechanism being actuatable to release the control mechanism from being locked to the handle assembly to allow the plurality of elongate members to be extended relative to the elongate barrel by the operator.
