Abstract: 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.

Abstract: A delivery system for deploying a medical implant includes a delivery wire assembly disposed within a delivery catheter lumen, the assembly having an implant loading region configured for seating the implant when the assembly is constrained within the delivery catheter lumen and the implant is in a compressed configuration, the assembly further including an implant distal protection having a central portion coupled to the assembly, distal of the implant loading region, and a peripheral portion extending proximally from the central portion to at least partially cover a distal end portion of the implant when the assembly, implant and distal protection are constrained within the catheter lumen, wherein the peripheral portion remains extending in the proximal direction when the implant assumes an expanded configuration after being released from the catheter lumen, and the peripheral portion of the distal protection comprises a plurality of stems, each comprising a respective petal-like member.

Abstract: Methods and systems for delivering a tubular implant to a target location in a body lumen, wherein the tubular implant has a delivery length when in a radially collapsed, delivery configuration, and a foreshortened length shorter than the delivery length when in a radially expanded, implanted configuration. Respective markers are provided on a delivery catheter and on the tubular implant which provide a visual indication of the landing location of a foreshortened length of a last proximal portion of the tubular implant prior to implanting the last proximal portion. This allows the clinician to determine if the landing location of the last proximal portion is clinically desirable prior to fully implanting the tubular implant.

Abstract: 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.

Abstract: 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.

Abstract: 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—allowing thrombosis within a volume formed by the ball.
