A device for treating a heart, the device comprising: an elongate member having first and second oppositely disposed ends; a first anchoring member attached to the first end of the elongate member; and a second anchoring member attached to the second end of the elongate member, wherein the first anchoring member is configured to engage a first exterior surface of a wall of the heart and the second anchoring member is configured to engage a second exterior surface of the wall of the heart to maintain a position of the elongate member transverse a heart chamber, and wherein at least one of the first and second anchoring members includes a mechanism to engage the elongate member and affix the elongate member to the at least one of the first and second anchoring members.
Claim 3
Dependent Claim
27 words
The device of claim 1 , wherein the mechanism is movable relative to a remainder of the at least one of the first and second anchoring members.
Claim 4
Dependent Claim
12 words
The device of claim 1 , wherein the mechanism is a screw.
Claim 5
Dependent Claim
30 words
The device of claim 1 , wherein the at least one of the first and second anchoring members defines a lumen through which the elongate member is configured to extend.
Claim 6
Dependent Claim
26 words
The device of claim 1 , wherein the at least one of the first and second anchoring members includes a channel configured to receive the mechanism.
Claim 7
Dependent Claim
43 words
The device of claim 5 , wherein the mechanism is configured to move within the channel between a first position in which the mechanism is not engaged with the elongate member and a second position in which the mechanism engages the elongate member.
Claim 8
Dependent Claim
39 words
The device of claim 1 , wherein the at least one of the first and second anchoring members is configured to be affixed to the elongate member after the elongate member is positioned with respect to the heart chamber.
Claim 9
Dependent Claim
18 words
The device of claim 1 , wherein each of the first and second anchoring members is substantially circular.
Claim 10
Dependent Claim
15 words
The device of claim 1 , wherein the elongate member includes a plurality of filaments.
Claim 11
Dependent Claim
15 words
The device of claim 9 , wherein the filaments are made of a polymeric material.
Claim 12
Dependent Claim
13 words
