摘要： Stents can become twisted during deployment within tortuous vessels such that proper expansion against the vessel wall is inhibited. Stents can be twisted prior to deployment in a direction opposite the direction of twisting during deployment to facilitate full expansion of the stent against the vessel wall along the stent's entire length.

摘要： An aneurysm therapy system is provided that can include a catheter and an occlusive device. The catheter can have a lumen extending between proximal and distal ends thereof. The occlusive device can be disposed within the catheter lumen and configured to reside in the aneurysm to restrict fluid flow within the aneurysm. The device can have a distal section that includes a coil having an outer diameter, a coil length, and a coil flexibility. The device can also include a self-expanding braided proximal section. The braided proximal section can be configured to expand during advancement out of the distal end of the catheter, and the distal section can be configured to distribute, along at least a portion of the coil length, a force of the advancement along an aneurysm interior wall.

摘要： A core member and associated systems and methods are disclosed herein. In some embodiments, the core member comprises a first portion including first and second materials, and a second portion distal to the first portion and including only the first material. The first and second portions can each be tapered in a continuous or discontinuous manner. The second portion can have a minimum length that is substantially straight and heat-treated or aged to have a minimum strength modulus.

摘要： Retrieval of material from vessel lumens can be improved by use of a distal element comprising an expandable mesh, a treatment device includes an elongated member having a proximal portion and a distal portion configured to be positioned within a blood vessel at a treatment site at or near a thrombus. A distal element comprising an expandable mesh is coupled to the distal portion of the elongated member via a connection assembly. In an expanded state, at least a portion of the mesh is configured to be in apposition with the blood vessel wall at the treatment site to anchor or stabilize the elongated member with respect to the blood vessel. The distal element can be electrically coupled to an extracorporeal current generator.

摘要： Treatment of an aneurysm or other vascular defect can be facilitated or enhanced by a galvanic cell formed by an implantable medical device configured to be implanted at or within the aneurysm or other vascular defect. The implantable medical device can include a primary structure including an anodic metal and a cathodic metal. The anodic metal and the cathodic metal each form a fraction of a total surface area of the primary structure. A galvanic cell formed by the anodic metal and the cathodic metal is configured to induce a galvanic voltage within blood for a duration of time to promote thrombosis. The thickness of the anodic metal can be less than or equal to 5 μm, for example, to provide galvanic activity for between 5 and 30 minutes.
