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.

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.

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.

Systems, apparatus, and methods for treating medication refractory epilepsy are disclosed. In one embodiment, a method of treating epilepsy is disclosed comprising detecting, using a first electrode array coupled to a first endovascular carrier, an electrophysiological signal of a subject. The method further comprises analyzing the electrophysiological signal using a neuromodulation unit electrically coupled to the first electrode array and stimulating an intracorporeal target of the subject using a second electrode array coupled to a second endovascular carrier implanted within a part of a bodily vessel superior to a base of the skull of the subject.

This disclosure provides design, material, preparation methods, and use alternatives for medical devices. An example method of preparing a stent comprises applying a coating to a portion of the stent at a medical treatment facility, the coating including a plurality of radioactive elements and a substrate. The plurality of radioactive elements are mixed with the substrate to form a mixture such that the plurality of radioactive elements are dispersed within the substrate prior to the coating being applied on the stent.

The present disclosure relates to methods and systems for manufacturing rotational spun materials. The rotational spun materials are medical appliances or other prostheses made of, constructed from, covered or coated with rotational spun materials, such as polytetrafluoroethylene (PTFE).

A prosthesis delivery comprising a rotatable inner cannula and a prosthesis releasably coupled to a proximal end of the inner cannula is disclosed. The inner cannula has a first position in which the prosthesis is retained on the cannula and a second position in which the prosthesis is released. At least one magnet is disposed on the inner cannula. A handle assembly is disposed about a distal portion of the inner cannula, the handle assembly comprising a rotary collar having at least one magnet disposed on the inner surface thereof, wherein the at least one magnet disposed on the rotatable inner cannula and the at least one magnet disposed on the inner surface of the rotary collar comprise a magnetic attraction. The magnetic attraction translates torque from rotation of the rotary collar to rotate the inner cannula from the first position to the second position to thereby release the prosthesis.
