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.

摘要： A medical device configured to perform an endovascular therapy can include an elongate manipulation member and an intervention member. The elongate manipulation member can include a distal end portion. The intervention member can include a proximal end portion and a mesh. The proximal end portion can be coupled with the distal end portion of the elongate manipulation member. The mesh can have a plurality of cells in a tubular configuration and being compressible to a collapsed configuration for delivery to an endovascular treatment site through a catheter and being self-expandable from the collapsed configuration to an expanded configuration. The mesh can include an anodic metal and a cathodic metal. The anodic metal and the cathodic metal can each form a fraction of a total surface area of the mesh.

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 a plurality of woven filaments defining a shaft at a proximal portion and a body distal of the shaft is coupled to the distal portion of the elongated member via a connection assembly. In an expanded state, at least a portion of the distal element 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： Systems and methods for detecting and disrupting obstructions (such as clot material) within a blood vessel are disclosed herein. In some examples, the present technology comprises a system for detecting and disrupting a clot in a cerebral blood vessel of a patient, where the system comprises a treatment environment, a detection system, and an energy delivery device. The detection system may be configured to determine the presence of a blood clot within a cerebral blood vessel of a patient. In some embodiments, the detection system is configured to obtain data characterizing a position of the clot within the treatment environment. The energy delivery device can be configured to receive the data characterizing the position of the clot and, based on the data, deliver energy to the clot, thereby disrupting the clot and restoring blood flow in the affected blood vessel.

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 electrically enhancing attachment of the material to the thrombectomy system. The system can an interventional element configured to be delivered to a treatment site and to be electrically coupled to an extracorporeal power supply. The interventional element can be surface treated (e.g., via electrochemical anodization) to achieve a desired electrical conductivity gradient over the surface of the interventional element. The electrical conductivity gradient can result in a more desirable surface charge distribution upon delivery of electrical current to the interventional element.
