摘要： An aspiration catheter including an elongate body and an expansile distal tip continuous with the elongate body. An expanding assembly is alignable internal to the expansile distal tip and connected proximally to a control wire. The expanding assembly includes a proximal position within the expansile distal tip proximal of a distal most end of the expansile distal tip. In a distal position where the expanding assembly is distally moved, by the control wire, until being aligned with and contacting the distal most end of the expansile distal tip causing the expansile distal tip to form a funnel mouth to receive clot.

摘要： A system for removing occlusive clot from a blood vessel comprises a catheter and an apparatus for generating a pulsatile vacuum force to pulse the pressure gradient at a distal end of the catheter. The pulse generator may be integral with or separate from the vacuum pump. The pulse generator may be applied to a flexible tubing between the vacuum pump and the proximal end of the catheter.

摘要： A system for removing an obstruction from a blood vessel. The system can include a catheter with a proximal section with a proximal section lumen diameter, a distal section with a distal section lumen diameter less than the proximal section lumen diameter, an intermediate section extended between proximal and distal sections. The system can include a clot retrieval device with a clot engaging element. The system can include a shaft being advanceable through the lumen of the catheter the obstruction of the blood vessel, the shaft can include a shaft proximal section; a shaft distal section attached to the clot engaging element and configured to cross the obstruction, a diameter of the shaft proximal section being greater than a diameter of the shaft distal section thereby inhibiting the shaft proximal section from distally advancing through the catheter distal section.

摘要： An embolic occlusion device for the treatment of aneurysms and arteriovenous malformations comprises expanded polytetrafluoroethylene (ePTFE). The ePTFE permits ingrowth of cells with connective tissue deposition to promote adherence of the aneurysm wall to the embolic device thereby preventing continued growth or re-growth of the aneurysm as well as blocking blood flow into an aneurysm. An occlusion device is also described which comprises an embolic element and a polymeric pre-formed component.

摘要： A clot removal device for removing clot from a body vessel comprises an expandable structure and an elongate member. The expandable structure has a constrained delivery configuration, an expanded clot engaging deployed configuration, and an at least partially constrained clot pinching configuration. At least a portion of the expandable structure is configured to engage clot in the expanded deployed configuration and to pinch clot on movement from the deployed configuration to the clot capture configuration. The expandable structure may comprise a main body portion and a clot pinching structure and a diameter of the clot pinching structure is less than a diameter of the main body portion. The clot pinching structure may be substantially tubular and of spiral form.

摘要： A clot retrieval device 1 for removing occlusive clot from a blood vessel, the device comprises an inner elongate body 3 having a collapsed delivery configuration and an expanded deployed configuration and an outer elongate body 2 at least partially overlying the inner elongate body 2. The outer elongate body 2 is expandable to a radial extent which is greater than the radial extent of the inner body 3 in the deployed configuration to define a clot reception space 11. The outer elongate body 2 comprises a distal end portion 24,49 and the inner elongate body 3 comprises a main body portion 10 and a distal portion which extends in the deployed configuration towards the outer elongate body 2 to a greater extent than the main body portion. The distal portion 10 of the inner elongate member 3 and the distal end portion 24,49 of the outer elongate body 2 together define a three dimensional protective structure to substantially prevent distal egress of clot or clot fragments from the device.
