摘要： Described are methods and systems for transcervical access of the cerebral arterial vasculature and treatment of cerebral occlusions, including ischemic stroke. The methods and devices may include methods and devices which may provide aspiration and passive flow reversal, those which protect the cerebral penumbra during the procedure to minimize injury to brain, as well as distal catheters and devices to remove an occlusion. The methods and devices that provide passive flow reversal may also offer to the user a degree of flow control. Devices and methods which provide a way to securely close the access site in the carotid artery to avoid the potentially devastating consequences of a transcervical hematoma are also described.

摘要： An endoscope treatment tool includes: a sheath having a lumen; a basket section protruding from the lumen and having an elastic wire; and an operating wire. The elastic wire has: a maximum section where the outer diameter of the basket section is largest of the elastic wire; a first section that, in a lateral view from a direction orthogonal to a normal from the maximum section to the central axis of the basket section, is largest on the opposite side of the central axis from the maximum section between the maximum section and the proximal end; and a second section that is largest at a position away from the normal between the maximum section and the first section, and in the front view, the first section is located on the opposite side of a straight line orthogonal to the normal at the central axis from the maximum section side.

摘要： An interventional catheter for treating an artery includes an elongated body sized and shaped to be transcervically introduced into a common carotid artery at an access location in the neck. The elongated body has an overall length such that the distal most section can be positioned in an intracranial artery and at least a portion of the proximal most section is positioned in the common carotid artery during use.

摘要： An apparatus is provided for removing material within a body lumen that includes a catheter including a proximal end, a distal end for introduction into a body lumen, and an aspiration lumen extending therebetween; a guide member extending from the distal end and terminating in a distal tip, the guide member comprising a track adjacent a track lumen extending from the distal tip into the aspiration lumen; and an obstruction clearing device deployable from the guide member and retractable along the track. In addition or alternatively, the apparatus includes a cutting head reciprocable within the aspiration lumen adjacent the distal end for macerating material being aspirated into the aspiration lumen.

摘要： A biomedical shape-set textile structure based mechanical thrombectomy systems and methods are described. In one of the embodiments, the mechanical thrombectomy device can be customized to the length of the clot in each patient. In one of the embodiments, the mechanical thrombectomy device because of the textile structure has a very low overall profile or thickness that is less than 0.0125 inches (0.317 mm) and therefore can be deployed within microcatheters with inner lumen diameter as small as 0.014 inches (0.355 mm).
