Heart valve implants and methods for implanting and delivering same are described. A heart valve implant can include a shaft, having a first end and a second end, an anchor, and a plurality of wafers. The anchor is coupled to the first end of the shaft and configured to secure the heart implant to a patient's heart. The wafers are coupled to the second end of the shaft and configured to form a stacked array of wafers. The stacked array of wafers can partially reduce a flow of blood through a heart valve upon coming in contact with a portion of a leaflet of the heart valve.

SELF-GRIPPING HERNIA PROSTHESIS

A self-gripping hernia prosthesis including a layer of repair fabric and a plurality of tissue grips protruding from a surface of the repair fabric. The grip may be fabricated independent of the repair fabric and subsequently attached to the layer of fabric. A backing layer may be employed to secure each grip to the repair fabric. Each base may include a base that is located between the repair fabric and the backing layer. Alternatively, the base may be attached directly to the backing layer. The tissue grips may be configured to minimize entanglement with the repair fabric.

METHODS AND SYSTEMS FOR DELIVERING A FILLED PROSTHETIC BLADDER INTO A SURGICAL CAVITY

A prosthetic insertion apparatus and related methods of use in delivering filled prosthetic bladders through a skin incision and into a surgical cavity or pocket. The prosthetic insertion apparatus imparts control and retention properties to a surgical professional such the prosthetic bladder can be oriented and manipulated into the surgical cavity without risk of inadvertent dropping of the prosthetic bladder and without imparting damaging stress or torque to the bladder. Suitable materials can be utilized that are selected as having advantageous properties including lubricity, rigidity, easily sterilizable, and high strength.

ORIENTABLE IMPLANTABLE DEVICE AND METHOD
20220054119 · 2022-02-24 ·

An intravascular system having a first catheter having a first non-circular transverse cross-sectional configuration and a first delivery device configured for insertion into the lumen of the catheter. The first delivery device includes an implantable medical device and an elongated member supporting the first medical device such that the first elongated member and the first medical device are movable through the lumen of the first catheter. The first elongated member has a second non-circular transverse cross-sectional configuration corresponding to the first non-circular transverse cross-sectional configuration to thereby inhibit rotation of the first elongated member within the catheter and control orientation of the first medical device relative to the catheter.

Intraocular lens, in particular capsular sac intraocular lens
09820849 · 2017-11-21 · ·

The present invention relates to an intraocular lens, in particular capsular intraocular lens, with at least an anterior, a posterior optic element, a haptic element connecting both optic elements, wherein a cavity is formed by the optic element, and haptic elements, which are opened by circumferentially arranged openings. The object of the present invention is to provide an intraocular lens that allows a symmetrical deformation of one or more optic elements of the intraocular lens as well as a relative displacement of these optic elements relative to each other on their optic elemental axis, so that a sufficient change in refractive power is obtained. This object is met by an intraocular lens, wherein it is provided that the area of the cavity between the optic elements comprises a filling that is at least partially enclosed by a membrane that a) is formed as a bag and completely encloses the filling, b) is ring-shaped and is connected to the anterior and posterior optic element or c) closes the openings The present invention further relates to an intraocular lens having at least an anterior and a posterior optic element and a haptic element interconnecting both optic elements. According to the invention the haptic element forms an overhang at the transition to the anterior optic element, wherein the anterior surface of the haptic element anterior extends beyond the edge of the anterior optic element or the haptic element forms an overhang at the transition to the posterior optic element, whereby the posterior surface of the haptic element posterior protrudes over the edge of posterior optic element, wherein the anterior or the posterior optic element is preferably embodied as a pinhole.

INTRAVASCULAR IMPLANTS
