Abstract

Apparatus is provided, comprising (1) a guide member, (2) a tissue-adjustment mechanism having (a) an upper surface and a lower surface, (b) at least one first opening at the upper surface, (c) at least one second opening at the lower surface, and (4) a channel extending between the first and second openings, the channel facilitating advancement of the tissue-adjustment mechanism along the guide member; and (3) at least one repair chord coupled at a first portion thereof to the tissue-adjustment mechanism and having at least a first end that is configured to be coupled to a portion of tissue of a patient, the repair chord being configured to adjust a distance between the portion of tissue and the tissue-adjustment mechanism, in response to adjustment of the repair chord by the tissue-adjustment mechanism. Other embodiments are also described.

Claims

1. Apparatus, comprising:

a guide member;

a tissue-adjustment mechanism having;

an upper surface and a lower surface,

at least one first opening at the upper surface,

at least one second opening at the lower surface, and

a channel extending between the first and second openings, the channel facilitating advancement of the tissue-adjustment mechanism along the guide member; and

at least one repair chord coupled at a first portion thereof to the tissue-adjustment mechanism and having at least a first end that is configured to be coupled to a portion of tissue of a patient, the repair chord being configured to adjust a distance between the portion of tissue and the tissue-adjustment mechanism, in response to adjustment of the repair chord by the tissue-adjustment mechanism.

2. A method, comprising:

coupling a guide member to a portion of tissue of a patient; and

advancing a tissue-adjustment mechanism toward the portion of tissue by;

threading a portion of the guide member through at least one channel extending between a first opening in an upper surface of the tissue-adjustment mechanism and a second opening in a lower surface of the tissue-adjustment mechanism; and

advancing the tissue-adjustment mechanism along the guide member and toward the portion of tissue.
