Implant having multiple rotational assemblies

摘要

Apparatus is provided, comprising (1) an annuloplasty structure, shaped to define a perimeter, and configured to be disposed at the annulus of the native valve of the patient; (2) a first adjusting mechanism, coupled to the annuloplasty structure, and configured to adjust the perimeter; (3) at least one longitudinal flexible member, having a first end portion, and a second end portion that is configured to be coupled to tissue of the ventricle of the heart of the patient; and (4) at least a second adjusting mechanism, coupled to the annuloplasty structure such that the second adjusting mechanism is slidable around at least part of the perimeter, coupled to the first end portion of the longitudinal flexible member, and configured to adjust a distance between the second adjusting mechanism and the second end portion of the longitudinal flexible member. Other embodiments are also described.

1. Apparatus for use with a native valve of a heart of a patient, the native valve having a valve annulus, and the heart having a ventricle, the apparatus comprising:
an annuloplasty structure, shaped to define a perimeter, and configured to be disposed at the annulus of the native valve of the patient, the annuloplasty structure comprising:
a body portion that defines a lumen therethrough; anda flexible longitudinal contracting member, having a first end portion, a second end portion, and a middle portion between the first and second end portions, the middle portion being disposed within the lumen of the bod portion; a first adjusting mechanism, coupled to the annuloplasty structure, and configured to adjust the perimeter of the annuloplasty structure, wherein at least one of the end portions of the flexible longitudinal contracting member is coupled to the first adjusting mechanism; at least one longitudinal flexible member, having a first end portion, and a second end portion that is configured to be coupled to tissue of the ventricle of the heart of the patient; and at least a second adjusting mechanism:
coupled to the annuloplasty structure such that the second adjusting mechanism is slidable around at least part of the perimeter of the annuloplasty structure,coupled to the first end portion of the at least one longitudinal flexible member, andconfigured to adjust a distance between the second adjusting mechanism and the second end portion of the at least one longitudinal flexible member.
