The invention provides keratoprosthesis devices and kits and surgical methods of their use.

The present disclosure is related to medical devices, stents, drainage devices, and the like, which feature a doubled back design. Various embodiments described herein have a portion with overlapping layers, at least one of which may comprise a cover.

An implantable device for treating a patient suffering from female urinary stress incontinence includes an elongate sling for supporting the urethra, the sling having first and second ends. First and second tabs extend from the first and second ends of the sling, respectively for engaging supportive tissue superior to the portion of the urethra being supported. Each tab has a ratcheted section of alternating relatively projecting and relatively recessed portions for engaging the supportive tissue.

Aspects of the present invention relate to a method for locating an expandable implant for treating BPH within the prostatic urethra of a patient. The delivery device comprises an inner tube and an outer sleeve moveable relative to the inner tube between a stored position and a deployed position. The outer sleeve surrounds the inner tube to define an annulus therebetween and the expandable implant is retained within the annulus when the outer sleeve is in the stored position.

An exchangeable optics system includes an intraocular base that can be fixed within an eye. The intraocular base includes one or more couplers and a supporting structure. The one or more couplers releasably couple to an exchangeable optic or therapeutic and can include magnetic material. The supporting structure can include haptics and a main structure that physically supports the exchangeable optic or the therapeutic that is coupled via the one or more couplers. In some cases, the intraocular base can include a fixed lens within or on the main structure. The exchangeable optic can include corresponding one or more couplers, which may be formed of magnetic material. The therapeutic can be in the form of a magnetic particle.

Devices, systems and methods are described for implantation of a prosthesis within a lumen or body cavity and delivery systems for delivering the prosthesis to a location for implantation. A delivery system can include a tether connected to a single directional handle knob for release of the prosthesis within the lumen or body cavity and retraction of the tether towards the handle.

A breast implant includes an outer shell made of a polymer and a filler material disposed within the outer shell. At least one opaque marking is disposed on the outer shell. The opaque marker is visible through the skin when a light emitter emits light through the chest tissue. This allows a user to determine if the breast implant is flipped or rotated based on the location of the opaque marker.

An airway support device of the present disclosure can be attached to tracheal and/or bronchial cartilage on opposing sides of a tracheal and/or bronchial wall to pull the tracheal and/or bronchial cartilages toward each other to reconstruct and/or reshape to a normal anatomy across the membranous tracheal and/or bronchial wall and thus relieving tension across the tracheal and/or bronchial wall. The airway support device can include at least two longitudinal strips that extend longitudinally along and are attached (e.g., sutured) to the trachea and/or bronchus on opposite sides of the tracheal and/or bronchial wall. Pairs of lateral strips extending from each of the longitudinal strips can be attached to each other under tension. The tracheal and/or bronchial wall can be attached (e.g., sutured) to the lateral strips to open the airway of the trachea and/or bronchus.

Described is a refractive phakic lens that has haptics extending away from the optical portion and in which the haptics have a compressible and release portion in the form of reversed undulation shape and at the end of the reversed undulation is a haptic pad that contacts the sulcus. Also, there is a rim structure on the posterior surface of the optic member which extend circumferentially but has interruption. Also, there is an opening at the optical axis of the lens member. Thereby fluid can flow through the opening and through the interruptions.

A system for repairing a defect on an articular surface of a patient's trochlear region, the system comprising a guide block comprising a body having an exterior surface configured to engage with the saddle portion and ridge portions of the patient's trochlear region, a protrusion extending generally from the body and configured to be received in a first bore formed in the articular surface along a reference axis, and a first cavity extending through the body configured to establish a first working axis displaced from the reference axis, wherein the exterior surface of the body and the protrusion are configured to secure the location of the guide block about the patient's trochlear region. A method for preparing an implant site in bone, comprising: establishing a reference axis extending from the bone; creating a bore in the bone by reaming about the reference axis; securing a guide block about the articular surface; establishing a first working axis extending from the bone using the guide block, the first working axis is displaced from the reference axis; and creating a first socket in the bone by reaming about the first working axis, wherein the first socket partially overlaps with the bore.
