Presbyopia is treated by implanting within a plurality of elongated pockets formed in the tissue of the sclera of the eye transverse to a meridian of the eye, a prosthesis having an elongated body having a first surface and a second surface opposite the first surface to contact the base and flap of the scleral pocket. The first and second surfaces are spaced apart a distance so that the implanted prosthesis exerts an outward force on the flap of the scleral pocket which results in an outward traction on at least the anterior margin of the scleral pocket. The combined effect of the implanted prostheses is to exert a radially outward traction on the sclera in the region overlying the ciliary body which expands the sclera in the affected region together with the underlying ciliary body. The expansion of the ciliary body restores the effective working distance of the ciliary muscle in the presbyopic eye and thereby increases the amplitude of accommodation. Hyperopia, primary open angle glaucoma and / or ocular hypertension can be treated by increasing the effective working distance of the ciliary muscle according to the invention. A preferred embodiment of the scleral prosthesis has a major surface adapted to contact the base or flap of the pocket and an opposite surface or ridge spaced from the major surface.

A system for implanting a prosthesis includes a control lumen and a nose cone affixed at a distal end of the control lumen. At least one supporting wire is affixed at one end, is substantially parallel to a major axis of the control lumen and is free at an opposite end, wherein the free end of at least one of the supporting wires is arcuate. Alternatively, a system for implanting a prosthesis includes at least one suture extending from a nose cone affixed to a distal end of a control lumen. The suture extends from the nose cone to a proximal end to a stent graft extending about the control lumen and from the stent graft to a fixed location on the control lumen. The suture is releasable from the stent graft by remote activation, whereby the suture separates from the nose cone to thereby deploy the stent graft.

Presbyopia is treated by implanting within a plurality of elongated pockets formed in the tissue of the sclera of the eye transverse to a meridian of the eye, a prosthesis having an elongated base member having an inward surface adapted to be placed against the inward wall of the pocket and having a ridge on the inward surface of the base extending along at least a major portion of the major dimension of the base. The combined effect of the implanted prostheses is to exert a radially outward traction on the sclera in the region overlying the ciliary body which expands the sclera in the affected region together with the underlying ciliary body. The expansion of the ciliary body restores the effective working distance of the ciliary muscle in the presbyopic eye and thereby increases the amplitude of accommodation. Hyperopia, primary open angle glaucoma and / or ocular hypertension can be treated by increasing the effective working distance of the ciliary muscle according to the invention.

Systems and method implant prostheses in the body. The systems and methods provide permanent attachment of the prosthesis in the body. The prosthesis can comprise, e.g., an endovascular graft, which can be deployed without damaging the native blood vessel in either an arterial or a venous system. The endovascular graft can comprise, e.g., a radially expanding vascular stent and / or a stent-graft. The graft can be placed in the vasculature, e.g., to exclude or bridge an aneurysm, for example, an abdominal aortic aneurysms. The graft desirably adapts to changes in aneurysm morphology and repairs the endovascular aneurysm. The fastening systems and methods can be deployed through the vasculature and manipulated from outside the body, to deliver a fastener to attach the graft to the vessel wall.

Bioabsorbable drug delivery devices including modular drug delivery devices having shapes and sizes adapted to be inserted within a recess on the surface of an implantable prosthesis are disclosed. The devices may be attached to one another to create custom drug delivery devices having controllable drug release characteristics that depend on the composition of individual modules comprising the device. The modules may be cylinders, disks, tiles or tubes comprised of a bioabsorbable polymer and a therapeutic agent. The therapeutic agent(s) may be homogeneously distributed throughout the polymeric body of the device or contained within a cavity within a module comprising the device, or both. The device(s) may be threaded or attached to a prosthesis by a biodegradable adhesive. The modular devices may also be formed into tapered plugs for insertion into a mating receptacle. In another embodiment, the drug delivery device may be inserted within a mesh bag that may be attached to a soft tissue as, for example, by sutures, for localized controlled dispensation of a therapeutic agent.

An implantable prosthetic device has a coaption element and at least one anchor. The coaption element is configured to be positioned within the native heart valve orifice to help fill a space where the native valve is regurgitant and form a more effective seal. The coaption element can have a structure that is impervious to blood. The coaption element can be connected to leaflets of the native valve by the anchor.

The surgical device according to the invention comprises both means for per-operative measurement and for memorization of a plurality of positions of a given femoral prosthetic direction and means for per-operative comparison of these positions with the cone of mobility of the prosthesis to be implanted, the position of the axis of revolution of this cone being, during the implantation of the prosthesis, adjustable with respect to the zone of the pelvis where the implantation of an acetabulum of the prosthesis is provided. By using this device, the surgeon can easily and rapidly determine, in the course of the surgical operation, a preferential direction for implanting the prosthetic acetabulum in order to reduce the subsequent risks of dislocations of the implanted prosthesis.
