An implant in which the Lobus medius (median lobe) can be treated in a simple and reliable manner. This is achieved by virtue of the fact that an implant for the treatment of a urinary tract has a wire structure. The wire structure has a loop wire, which can be expanded to form a loop, wherein at least two net wires can be stretched in this loop and the wire structure can be placed around the median lobe.

An implant with which a urinary tract can be treated in a simple and reliable manner is achieved in that a wire structure of an implant can be introduced into the urethra in a folded state with a distal end in the lead. The wire structure is unfolded inside the urethra for the treatment of the tissue. The ischemic pressure of the wires on the surrounding tissue results in denaturation. At least one further device for constricting or cutting into tissue is positioned on the wire structure. This at least one further device is designed in such a way that it exerts a local ischemic pressure on the median lobe in the unfolded state of the implant.

An implant for efficient and gentle treatment of the urinary tract. This is achieved in that an implant has a pressure means structure, which is constructed from at least two pressure means. These pressure means are of rod-like design and exert a local ischemic pressure on the tissue of the urethra. In addition, the pressure means are secured with their distal ends on a common distal connecting body and with their proximal ends on a common proximal connecting body, wherein the distal connecting body is secured in a fixed manner to a tightening means and the proximal connecting body is movably mounted on the tightening means.

A prosthetic heart valve can include an expandable support stent, a valve assembly, and a connecting membrane. The support stent can have first and second end portions and can be configured to be radially expandable from a first configuration to a second configuration. The valve assembly can have an inlet portion, an outlet portion, and a plurality of leaflets, and the valve assembly can be supported in the support stent. The connecting membrane can be disposed radially between the support stent and the valve assembly, wherein the support stent and the valve assembly can be connected to the connecting membrane.

The invention relates to endovascular medical implant devices and materials of composition for forming these devices to provide improved mechanical properties and biodegradability. The devices include a combination or integration of superelastic material, biodegradable metal and, thin film nitinol and/or biodegradable polymer. A structural frame is formed of individual elongated pieces composed of biodegradable metal. These pieces are joined together by connector pieces composed of superelastic material. At least a portion of the structural frame has deposited thereon the thin film nitinol and/or biodegradable polymer. The structural frame of the device is collapsible for insertion in a delivery tube and, recoverable for deployment and placement in a vascular location of a patient body.

A method for controlling intraocular pressure in a patient’s eye is provided. The method includes creating an intraocular entry into the eye, selecting a location along an optical disc of the eye, creating a conduit connecting at least a portion of an intravitreal cavity with at least a portion of a subarachnoid space in the eye at the selected location, deploying at least one stent communicating between the intravitreal cavity and the subarachnoid space via the conduit, and equilibrating the intraocular pressure in the eye by allowing the stent to communicate fluid flow between the intraocular compartment and the subarachnoid space.

The present disclosure is directed to a branched endoprosthesis comprising a graft component and at least one support component. In various embodiments, the branched endoprosthesis comprises a body portion and a plurality of leg portions, wherein the legs are in an aligned configuration for ease of cannulation. In various embodiments, at least one leg is in an open configuration for ease of cannulation. Cannulation methods are also described.

An apparatus for treating an aneurysm in a blood vessel includes a wire to be advanced within a tube and an occlusion element disposed on the wire. The occlusion element includes a cover and an inner anchoring member. The occlusion element is configured to fit within the tube and slide out of an opening at distal end of the tube in response to movement of the wire. The cover is configured to expand to an expanded configuration when advanced into the aneurysm, wherein the cover comprises a diameter that is greater than the diameter of a neck portion of the aneurysm and is configured such that a first portion of the cover contacts an interior surface of the aneurysm and a second portion covers the neck portion of the aneurysm. The inner anchoring member extends from the cover portion and is configured to contact the interior surface of the aneurysm.

A shape memory material-based minimally invasive implantation with multi-axis curl self-expanding structure, and an implant having said structure: the implant comprises an actuating member, and the implant has a first shape and a second shape, the second shape having a larger area than that of the first shape; the implant is provided with a plurality of curling portions, and the actuating member may cause a curling portion to expand along a curling axis thereof, thereby transforming the implant from the first shape to the second shape. Different self-expanding structures may be designed by using the elasticity and memory effect of shape memory materials. Deploying functional modules, such as a circuit, a battery, a sensor, an energy collector and the like, on the structures may achieve more functions.

Methods for controlling properties of structural elements of implantable medical devices, where the structural elements contain shape memory alloys (SMAs) include promoting or inhibiting in vivo formation of R-phase crystal structure or converging or separating the R-phase from the austenite phase.
