An implant delivery system comprises an elongate tubular member having a lumen, a tubular implant coaxially disposed within the lumen of the elongate tubular member, and a delivery assembly having a distal portion coaxially disposed within tubular implant. The delivery assembly comprises a delivery wire, an engaging bumper fixedly coupled to the delivery wire, a stopper bumper fixedly coupled to the delivery wire, and a floating element slidably coupled around the delivery wire and disposed between the bumpers, thereby limiting linear translation of the floating element therebetween. The floating element has an engaging portion configured to engage the engaging bumper when the delivery wire is axially translated relative to the elongate member in a first direction. The floating element is configured to radially expand outward to frictionally engage the implant when the engaging portion of the floating element engages the engaging bumper.

Implant delivery system

An embolectomy device includes a tubular body having a plurality of interconnected primary struts that define a plurality of openings when the tubular body is in a radially expanded deployed configuration, and a plurality of secondary struts connected to the primary struts that move from being aligned with the primary struts to a non-aligned configuration in which the secondary struts extend at least partially into and/or across the openings, to thereby ensnare or encapsulate a vascular obstruction within the primary and secondary struts after the tubular body is deployed proximate the obstruction and allowed to expand into or through the obstruction.

Embolectomy devices and methods

A method of manufacturing a tubular medical implant, such as a stent, includes introducing a liquid polymer material into an axial lumen of an elongate metal tube, the metal tube having an inner wall defining the lumen; allowing the polymer material to solidify within the metal tube lumen, the solidified polymer forming a high friction surface in contact with the inner wall of the metal tube; securing the metal tube, including the solidified polymer material therein, to a collet of a laser etching system; and laser etching a predetermined pattern of openings in the metal tube.

Method of manufacturing implants

Braid-balls suitable for aneurysm occlusion and/or parent vessel occlusion/sacrifice (e.g., in treating neurovascular defects) are disclosed. Especially for aneurysm treatment, but also for either one of the aforementioned treatments, the form of the ball is very important. In particular, the density of the device is paramount in applications where braid itself is intended to moderate or stop blood flow&#x2014;allowing thrombosis within a volume formed by the ball.

Multiple layer filamentary devices for treatment of vascular defects

A medical assembly for delivering an implant comprising a tubular resilient implant defining an inner lumen, the implant comprising a plurality of engaging members extending proximally an end thereof, the implant having a delivery configuration, and a released configuration, and a delivery assembly for delivering the implant, the delivery assembly comprising an outer tubular member extending through the inner lumen of the implant, the outer tubular member having a plurality of slots receiving therethrough the engaging members, with the implant being disposed in its delivery configuration on an outer surface of the outer tubular member, an inner tubular member coaxially disposed within the outer tubular member and movable relative to the outer tubular member, the inner tubular member having a first axial position that restrains the engaging members, and a second axial position to thereby release the implant from the delivery assembly.

Implant delivery assembly and method of use

Embolic implants and methods of manufacture are disclosed. The implants may be used for occluding blood flow at endovascular sites. One use is in intracranial aneurysm emolization/occlusion and another in parent vessel occlusion (PVO) or sacrifice. Various features provide for improved use (e.g., regarding delivery, recapture, visualization and/or occlusion) and manufacturability.
