    摘要： An apparatus for treating an aneurysm in a blood vessel includes an occlusion element including a first tubular mesh having a first end and a second end coupled together at a proximal end of the occlusion element such that an intermediate portion of the first tubular mesh between the first end and the second end includes a substantially 180 degree turn, the intermediate portion of the first tubular mesh extending distally from the proximal end of the occlusion element, wherein the intermediate portion of the first tubular mesh has a collapsed configuration and is configured to expand to an expanded. In some embodiments, the apparatus further includes a second tubular mesh having a first end and a second end coupled to the proximal end of the occlusion element such that an intermediate portion of the second tubular mesh between the first end and the second end includes a substantially 180 degree turn. In some embodiments, the apparatus further comprises a cover coupled to the proximal end of the occlusion element.

    摘要： A system for measuring cardiovascular data includes an elongate member having a channel, a first expandable member carried by the elongate member and movable between a collapsed state and an expanded state by adjustment initiated externally of a subject, a first sensor disposed on a surface of the elongate member, second and third sensors disposed on a surface of the first expandable, a first optical sensor located at a first location in relation to the distal end of the elongate member and configured for obtaining photoplethysmographic data, and wherein the first expandable member in its expanded state is configured to interface with the subject's larynx for delivery of at least oxygen gas into the respiratory system of the subject, and the second and third sensors are configured to contact tissue in proximity to the larynx when the first expandable member is in its expanded state.

    摘要： A system for aspiration includes an aspiration catheter including an elongate shaft including an aspiration lumen, and an open distal end, an extension tube, the lumen of the extension tube configured to be hydraulically coupled to the aspiration lumen, a peristaltic pump configured for driving fluid through the extension tube, a compressible portion disposed between the distal end and the proximal end of the extension tube, the compressible portion configured to be coupled to the peristaltic pump, such that operation of the peristaltic pump drives fluid from the aspiration lumen from the distal end of the extension tube to the proximal end of the extension tube, and a controller configured to receive a first signal from the first sensor and configured to vary the operation of the peristaltic pump based at least in part on a first signal received from a first sensor coupled to the aspiration lumen or extension tube related to a change in the characteristic of flow.

    摘要： A method for treating a patient having thrombus includes providing a manipulation device including a housing configured to be supported by the hand of a user and having a distal and proximal end, a drive system disposed within the housing, and configured to rotate a rotation member, an engagement member coupled to the rotation member and configured to be removably coupled to an elongate medical device, an activation member carried by the housing such that it can be operated by at least a portion of the hand of the user when the housing is supported by the hand of the user, the drive system configured to apply motive force to the engagement member, securing an elongate member to the engagement member, introducing at least the distal end of the elongate member into a blood vessel adjacent a thrombus, operating the activation member to cause at least some rotation of the rotation member, which in turn causes at least some rotation of the distal end of the elongate member at or near the thrombus, and aspirating at least some of the thrombus with an aspiration catheter.
