Abstract
Abstract A method for applying a cardiac support device to a heart of a mammal includes surgically accessing a heart, providing a cardiac support device including a jacket, and positioning the jacket around at least a portion of the heart by applying a pulling force to the jacket. The step of positioning the jacket can include using a tool from a position superior to the heart to pull the jacket onto the heart. One device for placing a cardiac support jacket onto the heart includes first and second tubular walls. The second tubular wall is oriented within the first tubular wall and against an internal surface of the first tubular wall. The second tubular wall includes a plurality of grooves and has an open interior volume to hold the cardiac support jacket. Another device for placing a cardiac support jacket onto the heart includes a tubular wall having a plurality of lumens extending between opposite ends of the tubular wall.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
222 words
A method for applying a cardiac support device to a heart of a mammal; the method comprising: (a) surgically accessing a heart, including inserting a delivery device into a thorax of the mammal; the delivery device including a cardiac support device having a jacket; (i) the jacket comprising a continuous flexible mesh net with a base edge, an opposite apex, first and second lateral edges extending from the base edge, and an open slot between the first and second lateral edges; the slot extending from the base edge and terminating at the apex; (ii) the jacket further including: (A) a first anterior strand secured to the base edge adjacent to the first lateral edge; (B) a second anterior strand secured to the base edge adjacent to the second lateral edge; (C) a first posterior strand secured to the base edge and positioned closer to the first anterior strand than to the second anterior strand; and (D) a second posterior strand secured to the base edge and positioned closer to the second anterior strand than to the first anterior strand; and (b) positioning the jacket around at least a portion of the heart by applying a pulling force to the jacket including pulling each of the first anterior, second anterior, first posterior, and second posterior strands to pull the jacket around the heart.
Claim 2
Independent Claim
222 words
A method for applying a cardiac support device to a heart of a mammal; the method comprising: (a) surgically accessing a heart, including inserting a delivery device into a thorax of the mammal; the delivery device including a cardiac support device having a jacket; (i) the jacket comprising a continuous flexible mesh net with a base edge, an opposite apex, first and second lateral edges extending from the base edge, and an open slot between the first and second lateral edges; the slot extending from the base edge and terminating at the apex; (ii) the jacket further including: (A) a first anterior strand secured to the base edge adjacent to the first lateral edge; (B) a second anterior strand secured to the base edge adjacent to the second lateral edge; (C) a first posterior strand secured to the base edge and positioned closer to the first anterior strand than to the second anterior strand; and (D) a second posterior strand secured to the base edge and positioned closer to the second anterior strand than to the first anterior strand; and (b) positioning the jacket around at least a portion of the heart by applying a pulling force to the jacket including pulling each of the first anterior, second anterior, first posterior, and second posterior strands to pull the jacket around the heart.
