The present disclosure relates to an anchor. The anchor includes a suture bridge having a proximal end and distal end. The distal end of the suture bridge has a thickness greater than a thickness of the proximal end of the suture bridge. At least two ribs extend from the proximal end of the suture bridge to a proximal end of the anchor. At least one open helical coil wraps around the at least two ribs and extends, substantially, from the proximal end of the suture bridge to the proximal end of the anchor. The at least one open helical coil defines an internal volume communicating with a region exterior to the anchor through apertures between turns of the at least one open helical coil. The at least two ribs are engagable with a grooved shaft of a driver.

The disclosure relates to heart valve prostheses with the reduced need of pacemaker implantation and improved means for positioning the replacement heart valve. In one aspect of the present disclosure, the stent scaffold of the valve prosthesis includes axially extending locators. The locators may be positioned within the cusp of the native aortic valve. Placement of the locators within the cusps may prevent further proximal movement of the stent scaffold into the left ventricle. By adjusting the location of the proximal end of the locators with respect to the proximal end of the stent scaffold, infra-annular placement of the stent scaffold in the aortic annulus may be assured. In another aspect, means for visualizing the positioning of replacement heart valves at an implant site inside an individual's body is disclosed.

This document describes intraocular lenses and methods for their use. For example, this document describes intraocular lenses that are shaped with a concave posterior peripheral portion that mitigates occurrences of dysphotopsia. The intraocular lenses described herein are designed to reduce positive and negative dysphotopsias after cataract surgery.

This disclosure relates to a heart valve with improved functionality and durability.

The present invention relates to a synthetic prosthesis for tissue reinforcement comprising: a porous knit made from a monofilament of a synthetic biocompatible material, said knit defining two opposite faces, a first face and a second face, a synthetic non porous biodegradable film comprising at least a copolymer of at least ε-caprolactone, said film covering at least part of said first face, a synthetic biodegradable binder bonding said film to said first face, said binder comprising at least a polymer of ε-caprolactone, wherein said second face of said porous knit is left open to cell colonization. The invention also relates to a method for forming such a prosthesis.

The invention concerns a device for use in ligament surgery to locate the best graft attachment site, including parts thereof; a kit of parts for use in ligament surgery; and a method for performing ligament surgery.

Provided herein are devices used to reconstruct a natural lens capsule after a cataract surgery. The device has a ring-shaped rigid component, a ring-shaped flexible component and a groove disposed on an inner surface of the rigid component. The rigid component has a distal end attached to the ring-shaped flexible component and a proximal end that lies against Wieger's ligament when fitted within the natural lens capsule. The ring-shaped flexible component has a proximal end that is attached to the distal end of the rigid component and a distal end that contacts an anterior surface of the natural lens capsule when fitted therein. The groove is disposed to receive optics of an intraocular lens and/or the ledge is disposed to secure haptics thereof.

Aspects of the disclosure include a prosthetic heart valve including a stent structure forming a plurality of commissure posts, a valve structure supported by the stent structure, a base supporting the stent structure and at least one radiopaque element positioned around the base. The radiopaque element can include a band extending around the base. In some embodiments the band is coiled. The band can optionally include a badge with an indicator specifying properties of the valve and viewable under fluoroscopy. In some embodiments, the radiopaque element is a badge that can have an indicator. The radiopaque elements of the disclosure increase ease and accuracy in the positioning of a percutaneously delivered replacement valve within a previously implanted valve of the disclosure.

A device for delivering an implant to a surgical location of a patient is provided. In some embodiments, an example device includes a polymer body having first and second tapered sections and a sealed cavity defined by the polymer body. The polymer body is separable between the first and second tapered sections.

A patient-specific guiding system for guiding an instrument relative to a portion of an anatomical feature of a patient. The patient-specific guiding system includes a patient-specific guide. The guide includes a first portion having a first patient-specific inner surface that conforms to a first surface of the anatomical feature and an outer surface opposite the first patient-specific inner surface. The first portion also includes a guide surface for use in guiding the instrument relative to the anatomical feature. The guide also includes a second portion having a second patient-specific inner surface that conforms to a second surface of the anatomical feature and an outer surface opposite the second patient-specific inner surface. The second portion is removably connected to the first portion.
