CARDIAC HARNESS DELIVERY DEVICE
First Claim
1. A medical device, comprising:
- a deflector having a plurality of petals having a distal end and a proximal end;
a ring, the proximal end of the petals being attached to the ring;
the petals tapering from a relatively narrower proximal end to a relatively wider distal end; and
the petals being flexible so that the petals can be collapsed into a delivery configuration and flared radially outwardly into a deployed configuration.

Abstract
An apparatus for delivering a cardiac harness onto a heart includes an elongate body and a plurality of elongate push rods longitudinally movable with respect to the elongate body. The elongate body has a tubular housing that is sized to contain the cardiac harness which is removably attached to the push rods. The cardiac harness is releasably attached to the push rods such that advancement of the push rods in a distal direction moves the cardiac hearness from a compacted configuration in the housing to an expanded configuration outside the housing. A deflector is attached to the elongate body and is configured to flare radially outwardly. As the push rods advance out of the housing, the push rods slide over the deflector to more easily and safely advance over the enlarged heart and position the cardiac harness over the heart.

12. A medical device, comprising:
-
a deflector having a first ring with a plurality of first petals attached to the first ring, the plurality of first petals being spaced apart forming first gaps between adjacent first petals; the deflector also having a second ring with a plurality of second petals attached to the second ring, the plurality of second petals being spaced apart forming second gaps between adjacent second petals; and the first ring and the second ring being configured to interlock so that the first petals and second petals overlap. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

25. An apparatus for delivering a cardiac harness onto a heart, comprising:
-
an elongate body having a proximal portion and a distal portion, the distal portion having a tubular housing sized to contain the cardiac harness in a compacted configuration, the tubular housing having a proximal end, an open distal end, an inner surface, and an outer surface; a plurality of elongate push rods longitudinally movable with respect to the elongate body, the cardiac harness releasably connected to each of the push rods such that advancement of the push rods in a distal direction moves the cardiac harness from the compacted configuration in the housing to an expanded configuration outside the housing; a deflector sheath slidably mounted over the outer surface of the tubular housing for retaining the petals; and the petals being configured to be collapsed into the deflector sheath in a delivery configuration and flared radially outwardly in a deployed configuration so that the push rods and cardiac harness slide over the deflector as the harness slides over the heart. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33)

34. A method of delivering and mounting a cardiac harness on a heart, comprising:
-
providing a minimally invasive access site; advancing an elongated delivery device through the access site; extending a deflector out of the delivery device; advancing a cardiac harness out of the delivery device and over the deflector; the cardiac harness flaring outwardly as the harness advances over the deflector and onto the heart; and withdrawing the delivery device and deflector through the access site. - View Dependent Claims (35, 36)
