    Abstract: A catheter has an expansile tip 901 that can be delivered in a constricted form. The increased tip diameter facilitates the aspiration and removal of large clot volumes by increasing the area of the catheter tip that applies aspiration to the clot. The tip 901 comprises a support frame which can be cut from a metal or polymer tube, covered with a thin polymer sleeve 909 containing highly elastic properties. This construction provides good pushability and high compressive resistance. The cut pattern can contain axial connections of the support frame 908 and ring members 906, which will provide a large level of axial support, lateral flexibility and hoop strength to withstand aspiration. The tip of the device can contain a section 907 proximal of the highly flexible area 905 that can expand to except clot. This potential to increase body diameter facilitates the retrieval of large volume clots while the construction of the catheter provides good column stiffness to avoid axial collapse and still maintain good flexibility.

    Abstract: An occlusion apparatus comprises inner and outer sheaths and an expandable flexible tubular sleeve. The occlusion apparatus is advanced to a target site in the blood vessel. A dilator having a soft, compressible tip may be advanced through a lumen of the inner sheath to facilitate the advancement of the occlusion apparatus. The sheaths are translated relative to one another to expand the flexible tubular sleeve to a funnel shape with a distal flush portion contacting the blood vessel inner wall and a proximal tapered portion. The proximal portion is fluid permeable so that blood can pass through to apply pressure on the vessel wall through the distal portion. A capture or traction device can be advanced out of the inner sheath lumen and retracted back therein to capture thrombus. The distal portion of the device may comprise an expandable mesh braid with a memory characteristic to limit expansion.

    Abstract: A mechanical thrombectomy device system is disclosed that is made from a single piece of biocompatible material, including a proximal flow block portion/feature, and/or, a flow block feature in the device body portion, a guidewire like delivery portion and an expandable, treatment portion. The construction of the device from a single piece allows for a seamless transition from the delivery portion to the treatment portion, thus removing any joints or bonding of the two portions together as separate pieces. This improves the strength of the system as a whole and greatly reduces the possibility of the two parts unintentionally detaching from each other. Likewise, the distal treatment portion is cut from a piece of material the same size as the proximal delivery portion, allowing the device to be compacted to a similar size profile giving it delivery advantages including a lower delivery force required and requiring small access systems, and the treatment portion's surface can be altered to enhance embolus affinity by either coating with a substance or changing the texture by mechanical or chemical means.
