A tendon repair implant for treatment of a partial thickness tear in the supraspinatus tendon of the shoulder is provided. The implant may incorporate features of rapid deployment and fixation by an arthroscopic means approach that compliment current procedures; tensile properties that result in desired sharing of anatomical load between the implant and native tendon during rehabilitation; selected porosity and longitudinal pathways for tissue in-growth; sufficient cyclic straining of the implant in the longitudinal direction to promote remodeling of new tissue to tendon-like tissue; and, may include a bioresorbable construction to provide transfer of additional load to new tendon-like tissue and native tendon over time.

An accommodation-facilitating intraocular implant has: a ring sized to fit within a capsular lens bag of an eye; and a plurality of haptics angularly spaced around and radially extended from the ring. A multi-curve implantable accommodating intraocular lens has a convex anterior and concave posterior.

A device for lowering intraocular pressure is disclosed herein. In an example, the device includes a continuous plate structure that enables aqueous humor to flow from a first end to a second end. The first end has a maximum width that is narrower than a maximum width of the second end. The continuous plate structure includes an uppermost surface opposite a lowermost surface, the uppermost surface including a plurality of open cells. The continuous plate structure also includes a fluid pathway including a plurality of open channels formed into the lowermost surface. The open channels are configured in an intersecting grid pattern extending from the first end to the second end of the continuous plate structure. The open channels provide for the flow of aqueous humor, thereby reducing intraocular pressure.

The invention relates to a glenoid (shoulder socket) implant prosthesis, a humeral implant prosthesis, devices for implanting glenoid and humeral implant prostheses, and less invasive methods of their use for the treatment of an injured or damaged shoulder.

Some embodiments are directed to a transcatheter and serially-expandable artificial heart valve, e.g., to be minimally-invasively implanted into a pediatric patient during a first procedure, and then expanded during a second procedure to accommodate for the pediatric patient's growth. Some embodiments include an expandable frame having a compressed, delivery configuration, and an expanded, deployed configuration, in which the valve is implantable within the patient. The valve can have a first working condition when the frame is expanded to a first diameter and a second working condition when the frame is expanded to a second diameter greater than the first diameter. The valve can include a plurality of leaflets configured to accommodate the expansion of the frame and growth of the patient.

A biomimetic tissue scaffold for repairing an elongated tissue in need of repair can comprise a plurality of coiled flexible polymeric ribbons having a surface on which is formed an array of nanofibers, the ribbons forming a tubular body defining a first open end in which a first end of the elongated tissue is receivable, a second open end in which a second end of the elongated tissue is receivable, and a lumen extending between the first and second open ends.

There is disclosed a porous emboli deflector for preventing cerebral emboli while maintaining cerebral blood flow during an endovascular or open surgical procedure. The device prevents the entrance of emboli of a size able to cause stroke (such as greater than 100 microns) from entering either the right or left common carotid arteries, and/or the right or left vertebral arteries by deflecting emboli downstream of these vessels. The device can be placed prior to any manipulation of the heart or aorta allowing maximal protection of the brain during the index procedure. The deflector has a low profile within the aorta which allows sheaths, catheters, or wires used in the index procedure to pass. Also disclosed are methods for insertion and removal of the deflector.

A leaflet coaptation-assist device (920, 1020, 1120) is provided for promoting valve coaptation of leaflets (22) of an atrioventricular valve, the leaflet coaptation-assist device (920, 1020, 1120) including a coaptation-assist surface (964, 1064, 1164) and one or more tissue anchors, which are configured to anchor the leaflet coaptation-assist device (920, 1020, 1120) in place within the heart, such that the coaptation-assist surface (964, 1064, 1164) is located at or below the leaflet hinge line and contacts an atrial side of the leaflets (22) during ventricular systole, thereby enhancing leaflet coaptation. In some configurations, the one or more tissue anchors include one or more ventricular loops (988, 1088, 1188), which are configured to couple the leaflet coaptation-assist device (920, 1020, 1120) to the ventricular wall by radial force and friction. Other embodiments are also described.
