摘要： Apparatus and methods for occluding hollow body structures, such as blood vessels, and for attaching tissue layers together by providing implantable elements on opposite sides of the structure or tissue layers and drawing the implants together to occlude the body structure and/or bring the tissue layers together. The implants are deliverable in a low-profile configuration and self-expand to an enlarged configuration. The implantable elements are delivered by transfixing the body structure, then releasing the implants on opposite sides of the anatomical structure to urge the layers together to effect an occlusion or attachment. The implants are configured to apply oppositely directed forces to opposite surfaces of the tissue layers at alternate, circumferentially spaced locations and may constrain the tissue in a serpentine pattern or in a direct clamping pattern. The implants grip the tissue in a manner that defines a pressure zone about the transfixion aperture that prevents leakage from the aperture. The invention can be used to fasten tissue to non-tissue.

摘要： Described are methods, systems, devices for facilitation of intraluminal medical procedures within the neurovasculature. A catheter advancement device includes a flexible elongate body having a proximal end, a distal end, and a single lumen extending therebetween. The flexible elongate body has a proximal segment, an intermediate segment, and a tip segment. The proximal segment includes a hypotube coated with a polymer. The intermediate segment includes an unreinforced polymer having a durometer of no more than 72D. The tip segment is formed of a polymer different from the intermediate segment and has a durometer of no more than about 35D and a length of at least 5 cm. The tip segment has a tapered portion that tapers distally from a first outer diameter to a second outer diameter over a length of between 1 and 3 cm.

摘要： Disclosed herein is a device for disrupting material in a body vessel and a method for making such a device. The device includes a plurality of arms disposed circumferentially about an axis. Each arm includes two blades; one sharper, and one blunter. The sharper blades are all oriented in the same direction, clockwise or counterclockwise, such that when the device is rotated in a first direction, the sharper blades engage the material, and in the other, the duller blades engage the material.

摘要： Various devices, systems, and methods are provided for allowing surgical instruments to access a body cavity through an access device, such as a cannula. In one embodiment, a cap can be removably and replaceably coupled to a proximal end of cannula and can have an opening therethrough that communicates with an inner passageway of the cannula. Various surgical elements can be passed through the cap and cannula and into a patient when the cannula is positioned within the patient. The cap can have a side slot formed therein. The slot can be configured to allow surgical elements, such as sutures, to pass through the cap and into the cannula. At least one surgical seal can be in the cap and can be configured to receive surgical elements therethrough.
