摘要： A catheter or shaft, such as a distal access support or aspiration catheter, is provided that is configured to be advanced at least partially within a patient. The catheter or shaft may include a flexible and hollow shaft including a proximal end and a distal end. The flexible and hollow shaft may include a slotted portion with a plurality of slotted openings, the slotted portion including a first segment with a first pattern of slotted openings and a second segment extending proximally relative the first segment with a second pattern of slotted openings different from the first pattern.

摘要： The invention relates generally to methods and systems for capturing, filtering, or retrieving obstructions or other particulates from a patient's vasculature. In one aspect, device for retrieving an obstruction from a patient is provided that includes an outer delivery shaft and an expandable basket movable between a collapsed configuration and an expanded configuration. The basket is configured to be in the collapsed configuration during delivery and in the expanded configuration during engagement and retrieval of the obstruction. A proximal end of the basket is configured to be centrally and pivotally coupled to the outer delivery shaft. The proximal end and/or a distal end of the basket is movable relative to each other such that a proximal portion of the expandable basket is invertible toward a distal portion of the basket to form a proximally oriented cavity in the expanded configuration to engage and retrieve the obstruction.

摘要： Neurovascular flow diverter and delivery systems, and methods of using the same are disclosed herein. The systems can include an introducer sheath, a catheter, a deployable flow diverter that can be contained in the introducer sheath or in the catheter, a core wire, and one or several deployment features coupled to the core wire and engaging the flow diverter. The deployment features can include one or more of a pusher, one or several friction bumps, one or several deployment coils, a claw mechanism, a self-expanding element, a supporting coil, a tip coil, and/or an atraumatic tip. One or more of the deployment features can be radiopaque.

摘要： The invention relates generally to methods and systems for capturing, filtering, or retrieving obstructions or other particulates from a patient's vasculature. It may relate to integrated thrombectomy and filtering devices and methods of use. The methods and systems may be configured to remove obstructions such as clots or foreign body objects from a neurovascular vessel or other vasculature and/or provide protection from distal emboli. In one aspect, device for retrieving an obstruction from a patient is provided that includes an outer delivery shaft and an expandable basket movable between a collapsed configuration and an expanded configuration. The basket is configured to be in the collapsed configuration during delivery and in the expanded configuration during engagement and retrieval of the obstruction. A proximal end of the basket is configured to be centrally and pivotally coupled to the outer delivery shaft. The proximal end and/or a distal end of the basket is movable relative to each other such that a proximal portion of the expandable basket is invertible toward a distal portion of the basket to form a proximally oriented cavity in the expanded configuration to engage and retrieve the obstruction.

摘要： Neurovascular flow diverter and delivery systems, and methods of using the same are described herein. The systems can include a customizing member including an introducer sheath, a catheter, a deployable flow diverter that can be contained in the introducer sheath or in the catheter, a core wire, and one or several deployment features coupled to the core wire and engaging the flow diverter. The customizing member includes a tubing extending along and around a distal portion of the introducer sheath. This tubing is cuttable and contains a distal end of the flow diverter. The length of the flow diverter can be customized by cutting through the tubing and the therein contained flow diverter.
