Abstract: An embolic coil with a secondary, delivered shape utilizing regions of varying stiffness is described. In some embodiments, these regions of varying stiffness are created by utilizing a larger primary wind loop diameter to create selective regions with lower stiffness and higher flexibility. In some embodiments, these regions of higher flexibility correspond to inflection regions on a complex coil shape to ease deliverability of the coil during therapeutic procedures.
Abstract: A stent with varying porosity is described. The stent can be comprised of multiple stents attached together. A braided stent may have selected regions of increased thickness. The stent may be comprised of wires that are welded together at their ends in order to minimize vessel trauma. The stent may comprise a helically wound radiopaque wire wound through the stent.
Abstract: Devices, systems, and methods used to seal a treatment area to prevent embolic agents from migrating are described. The concept has particular benefit in allowing liquid embolic to be used with a variety of intravascular therapeutic applications, including for occluding aneurysms and arteriovenous malformations in the neurovasculature.

Abstract: A medical device is disclosed and may have a spiral shape structure that can function as a stent, such as a flow diversion stent to treat aneurysms. The medical device may have a spiral shape structure that can function as an occlusive device, for instance to occlude aneurysms. The medical device may include a shape setting structure to selectively adjust the shape of the medical device.
Abstract: A complex coil and a fixture for forming same configured such that loops are formed having various configurations relative to each other. The configurations provide improved thrombus formation and reduced rotation or tumbling once implanted. The complex coil is formed of a material that may deformed for purposes of placing the complex coil into a catheter and returns to a complex shape that includes said loops once deployed.

Abstract: A catheter system utilizing one or more sensors is described. The catheter can be used as part of an embolic coil system, guidewire system, or combined embolic coil/guidewire system where the devices interact with the catheter system. A variable detachment embolic coil system and guidewire system are also described.
Abstract: Disclosed is a method, apparatus, and kit for assisting the expansion of a self-expanding stent, especially within highly curved or tortuous blood vessels. An elongated pusher having an expandable distal mesh portion can be positioned within a self-expanding stent, expanding during delivery to provide extra expansion force to the stent to ensure the stent properly expands.
Abstract: An obstruction removal device is described, having one or more engaging members which can engage portions of the clot. The one or more engaging members have a collapsed, delivery state, and an expanded, deployed state.
Abstract: An occlusion device formed of a microcoil having a three-dimensional relaxed state employing open looped portions interposed between closed loop portions. Planes defined by sequentially formed open looped and closed loop portions are neither coincident nor parallel to one another.
Abstract: Embolic particles are described. The particles are reaction products of a prepolymer solution including at least one polyether macromer and an appropriate monomer.
