Patent US20050014992 - Device for treating heart failure - Google Patents
A cardiac harness is configured to fit about a portion of a patient's heart so as to exert a compressive force on the heart during at least a portion of the cardiac cycle. The harness can be constructed of a plurality of individual modules assembled ex vivo or in vivo. The modules can have different...http://www.google.ca/patents/US20050014992?utm_source=gb-gplus-sharePatent US20050014992 - Device for treating heart failure

1. A cardiac harness co to fit about a patient's heart, comprising a plurality of individual modules assembled together to form the harness.
11. The cardiac harness of claim 10, wherein the first and second modules are connected to one another by a coupling mechanism interposed between the modules.
13. The cardiac harness of claim 11, wherein the coupling mechanism comprises silicone.
17. A method of making a cardiac harness, comprising:
21. A method of treating a diseased heart, comprising
providing a cardiac harness configured to fit about a patient's heart and comprising a first end and a second end that are adapted to be coupled to one another;
placing the rolled cardiac harness adjacent a portion of the patient's heart; and
unrolling the harness so that the unrolled harness fits about the heart.
22. The method of claim 21 additionally comprising connecting the first and second ends to each other after the harness has been unrolled about the heart.
23. A method of deploying a cardiac harness about a patient's heart, comprising:
providing a deployment apparatus comprising a deployment member;
wrapping at least a portion of the harness about the deployment member;
positioning the deployment member adjacent the heart; and
moving the deployment member about the heart in a manner so that the harness unwraps from the deployment member onto the heart as the deployment member is moved about the heart.
24. The method of claim 23 additionally comprising rotating the deployment member while moving it about the heart.
25. The method of claim 23, wherein the deployment apparatus comprises a second deployment member.
26. The method of claim 25, additionally comprising wrapping a portion of the harness about the second deployment member so that the harness is wrapped in a scroll fashion about the first and second deployment members.
27. The method of claim 26 comprising simultaneously moving the first and second deployment members about opposite sides of the heart.
28. A cardiac harness, comprising a plurality of modules adapted to be coupled to each other, each of the modules comprising a plurality of spring elements.
29. A cardiac harness comprising a plurality of modules, each module having a first edge, a second edge, and a zip coupling mechanism for selectively drawing the firsf and second edges adjacent to one another.
30. A cardiac harness, comprising first and second modules and a zip coupler which connects said first and second modules to each other.
31. A cardiac harness configured to fit about a patient's heart, comprising a base portion, an apex portion and a medial portion between the apex and base portions, the apex portion comprising a plurality of spiral shaped elongate members, each spiral shaped elongate member connected at one end to the medial portion and at the other end to a terminal member.
32. The cardiac harness of claim 31, wherein the plurality of spiral shaped elongate members together form a generally conical shaped region of the harness.
33. A cardiac harness configured to fit about a patient's heart, comprising:
an apex portion; and
a medial portion between the apex and base portions;
the base portion comprising interconnected spring elements that are oriented so that the collective spring force around the circumference of the base portion is in a first direction;
the medial portion comprising interconnected spring elements oriented so that the collective spring force around at least a portion of the circumference of the medial portion is in a second direction substantially different than the first direction.
34. The cardiac harness of claim 33, wherein the second direction has significant spring force components in directions both transverse and parallel to a longitudinal axis of the harness.
35. A cardiac harness having a central cavity for receiving a portion of a patient's heart such that the harness contacts the wall of the heart substantially throughout said cavity, said harness having a plurality of protrusions extending inwardly such that interference between the protrusion and the wall of the heart aids retention of said harness on said heart.
36. The cardiac harness of claim 35, wherein at least one of the protrusions comprises a barb configured to pierce a portion of the heart wall.
37. The cardiac harness of claim 35, wherein at least one of the protrusions exerts a biasing force against the heart wall when the heart is disposed in the cavity.
In accordance with a ftuther aspect of the present invention, a method of making a cardiac harness comprises providing a plurality of modules and connecting the modules to one another to form the harness.
After the mating components 120 have been locked together, the coupling member 126 can be left in place or can be completely removed from the zip coupling mechanism 118. The mating components 120 will remain interlocked after the coupling member 126 is removed. However, with a conventional zipper, when the coupling member has been removed, there is a chance that the mating components will unlock from each other if the ends of the components are not held together. To counteract this possibility, a secondary coupling 128 is provided to hold the mating components 120 in an interlocked position at two or more locations along their length. The secondary coupling 128 prevents the mating-components from working apart from each other.
