Abstract
Abstract The apparatus includes and elongate body having a proximal portion and a distal portion. The body includes a cavity sized to contain a cardiac harness in a compacted configuration and also includes a plurality of elongate push rods movable with respect to the body. The cardiac harness is releasably connected to each of the push rods such that advancement of the push rods in a distal direction moves the harness from a compacted configuration, within the cavity, to an expanded configuration, outside the cavity. The apparatus also includes a releasing member for releasing the connections between the push rods and the harness upon actuation of the releasing member by a user.

Claim 3
Dependent Claim
24 words
The apparatus of claim 1 , additionally comprising a positioning arrangement configured to secure said apparatus in a desired position relative to a heart.
Claim 4
Dependent Claim
14 words
The apparatus of claim 2 , wherein said positioning arrangement comprises suction cup member.
Claim 5
Dependent Claim

The apparatus of claim 1 , additionally comprising a handle and a control assembly, said handle being fixed to said proximal portion of said elongate body and said control assembly supporting said plurality of elongate push rods.
Claim 6
Independent Claim
64 words
An apparatus for delivering a cardiac harness, comprising: a support member, said cardiac harness being preloaded on said support member and attached to said support member by a line, said line comprised of a series of interconnected loops which form a releasable stitch; and wherein said cardiac harness is releasably connected to each support member at at least first and second longitudinally spaced locations.
Claim 7
Independent Claim
64 words
An apparatus for delivering a cardiac harness, comprising: a support member, said cardiac harness being preloaded on said support member and attached to said support member by a line, said line comprised of a series of interconnected loops which form a releasable stitch; and wherein said cardiac harness is releasably connected to each support member at at least first and second longitudinally spaced locations.
Claim 8
Dependent Claim
50 words
The apparatus of claim 5 , wherein an end one of said interconnected loops of said stitch is retained by an anchoring member which prevents unravelment of said series of loops, and wherein the release of said loop from said anchoring member allows unravelment of said series of interconnected loops.
Claim 9
Dependent Claim
58 words
The apparatus of claim 6 , wherein said anchoring member is fixed for movement with a release member, an end of said line being attached to said release member, and wherein movement of said release member in a direction away from said support member releases said loop from said anchoring member and unravels said series of interconnected loops.
Claim 10
Independent Claim
167 words
An apparatus for delivering a cardiac harness, comprising: an elongate body having a proximal portion and a distal portion; a plurality of push rods longitudinally movable with respect to said body, said cardiac harness releasably connected to each of the push rods such that movement of said push rods in a distal direction advances said harness onto said heart, said harness being releasable from the push rods such that the push rods may be withdrawn from said harness proximally along a withdrawal path while said harness remains on said heart, said distal portion of said push rods having an inward facing surface which presses against said harness during said withdrawal, said inward facing surface configured such that non-frictional force -components parallel to said path and attributable to forces exerted by said inner surface on said harness are directed distally, without substantial non-frictional force components directed proximally; and wherein said cardiac harness is releasably connected to each push rod at at least first and second longitudinally spaced locations.
