Adjustable self-locking papillary muscle band
First Claim
1. A cardiac device, comprising:
- a band configured to form a loop within a heart, the band defining a lumen extending at least partially therethrough along an elongated axis of the band, wherein the band includes a first end, a second end configured to be received within the lumen via a first opening in the first end, and a side wall opening between the first end and the second end, the side wall opening providing access to the lumen; and
an actuatable clasp configured to transition from an open configuration to a closed configuration for forming a fixed length loop after the second end is inserted into the first end, and wherein the clasp is configured for actuation via a catheter passing through the side wall opening,wherein the actuatable clasp is configured to be held in the open configuration by a clasp retainer associated with the clasp; and
wherein the actuatable clasp is configured such that retraction of the clasp retainer from the clasp results in the clasp returning to its closed configuration.

Abstract
Embodiments of the present disclosure include a device for repositioning papillary muscles. The device may comprise a band configured to encircle a cluster of papillary muscles. The cluster of papillary muscles may have an outer peripheral boundary defined by the encircling band, and the band may comprise a first end and a second end. The device may further comprise an adjustable clasp coupled to a location proximate the first end of the band. The clasp may be configured to transition from an open configuration to a closed configuration to connect the second end of the band to the first end of the band, thereby forming a loop. The clasp may be selectively actuatable to adjust a length of the loop.

19. A cardiac device, comprising:
-
a band configured to form a loop within a heart, the band defining a lumen extending at least partially therethrough along an elongated axis of the band, wherein the band includes a first end, a second end configured to be received within the lumen via a first opening in the first end, and a side wall opening between the first end and the second end, the side wall opening providing access to the lumen; and an actuatable clasp configured to transition from an open configuration to a closed configuration for forming a fixed length loop after the second end is inserted into the first end, and wherein the clasp is configured for actuation via a catheter passing through the side wall opening, wherein the band includes a plurality of graspable elements proximate the second end of the band, forming protrusions between which the clasp is configured to lock when in its closed configuration, the graspable elements being configured for passage through the clasp in both a first direction and a second direction opposite the first direction when the clasp is in its open configuration, and being configured to prevent passage through the clasp in the second direction when the clasp is in its closed configuration.
