Abstract
A cardiac harness for treating or preventing congestive heart failure is configured to be placed about at least a portion of a patient's heart so as to apply a mild compressive force on the heart. In one embodiment, the cardiac harness comprises a plurality of spaced apart conductive panels arranged so that there is no electrical continuity circumferentially around the harness. In an additional embodiment, a cardiac harness is provided that is insulated so as not to conduct electricity circumferentially about the harness.
Claims35
A cardiac harness configured to fit about a patient's heart, the harness comprising:
- a first panel constructed of a first material;
- and
- a second panel constructed of a second material that is different than the first material;
- wherein the first and second panels are positioned adjacent one another.
A cardiac harness configured to fit about a patient's heart, the harness comprising:
- a plurality of conductive panels, each of the panels being spaced from an adjacent panel so that there is no electrical continuity between the conductive panels.
(canceled)
A cardiac harness configured to fit about a patient's heart, the harness comprising:
- a base end, an apex end, a right portion and a left portion, the right portion configured to be placed generally adjacent a right side of the patient's heart and the left portion configured to be placed generally adjacent a left side of the patient's heart, wherein a distance between the apex end and the base end in the right portion is greater than a distance between the apex end and the base end in the left portion.
A cardiac harness configured to fit about a patient's heart, said harness comprising:
- a plurality of interconnected spring members comprised of a conductive material, at least some of said spring members connected to other spring members by a dielectric material such that the dielectric connected spring members are substantially electrically insulated from each other.
A cardiac harness configured to fit about a patient's heart, the harness comprising:
- a conductive material, the conductive material being coated with a dielectric coating so as to electrically insulate at least the heart tissue from the conductive material.
30-44. (canceled)
A cardiac harness which circumferentially surrounds a patient's heart and extends longitudinally from an apex portion to a base portion of the heart, comprising:
- a first portion and a second portion, the first portion configured to be disposed closer to an apex portion of the heart then the second portion;
- the first portion comprising a plurality of interconnected panels that are electrically insulated from one another along respective longitudinal sides to inhibit electrical conduction circumferentially about said harness;
- and
- the second portion being electrically insulated from the first portion.
