Disclosed herein are various embodiments of suture adjustment mechanisms for anchors configured to be inserted into a heart wall of a patient to anchor a suture as an artificial chordae under an appropriate tension for proper valve function. Suture adjustment mechanisms can be configured to retain suture ends extending from the leaflet to the anchor with sufficient force to prevent natural movement of the leaflet from adjusting a length of the suture between the anchor and the leaflet. Free ends of the suture can extend from the anchor external to the body as tensioning strands. A surgeon can supply sufficient force on the tensioning strands from external the body to adjust a length and tension of the suture between the anchor and the leaflet.

Suture length adjustment for minimally invasive heart valve repair

Various embodiments of anchors are configured to be inserted into a heart wall of a patient to anchor a suture as an artificial chordae under an appropriate tension for proper valve function. Each of the disclosed anchor embodiments 'toggles' from a first position for delivery of the anchor to the heart wall and a second position for insertion of the anchor into the heart wall. In some embodiments, it is the 'toggle' to the second position that provides the insertion force for inserting the anchor into the heart muscle sufficient to retain the anchor from accidental withdrawal from the heart wall during normal valve operation (e.g., when a valve leaflet pulls on the suture attached to the anchor during systole). Such anchors are particularly suitable for use in intravascular, transcatheter procedures as described above given the inherent difficulties in providing sufficient force for insertion of an anchor into the heart wall with a flexible catheter.

Low profile tissue anchor for minimally invasive heart valve repair

A base for an orthopedic walking boot having a foot bed configured to support a plantar portion of a user's foot, a section extending from the foot bed configured to surround a portion of user's foot, and a connector assembly matable with each of a plurality of different types of support structures such that any one of the plurality of different types of support structures is selectively and permanently connectable to the base through the at least one connector assembly.

Modular system for an orthopedic walking boot

An orthopedic walking boot including a base to support a user's foot; a support assembly extending from the base to support the user's lower leg; and an outer sole overmolded to the base.

Overmolding for an orthopedic walking boot

A method of manufacturing an orthopedic walking boot, comprising providing a base configured to support a user's foot and receive a support assembly configured to support the user's lower leg; and overmolding an outer sole to the base.

An orthopedic walking boot, comprising a base to support a user's foot, the base having a section configured to support the user's posterior portion of the heel; a support assembly extending from the base to support the user's lower leg; and a heel cushion arranged with said section of the base to engage the user's posterior portion of the heel, the heel portion having a free edge configured to flex.
