Patent number: 9949739Abstract: A grip assembly for an embolic delivery device is described, where said grip assembly includes an integral wiping system utilizing one or more wipers. The grip assembly is constructed and arranged to allow an embolic delivery device to be inserted into the grip quickly and easily, without shifting undue attention away from the patient to the device. The wiper or wipers prevent any fluids or debris that may be present on a proximal end of the embolic delivery device from entering the interior of the grip assembly, thereby preserving a clean environment for making solid electrical connections between contacts in the grip assembly and corresponding contacts on the embolic delivery device.Type: GrantFiled: February 27, 2014Date of Patent: April 24, 2018Assignee: MicroVention, Inc.Inventors: Ross Tsukashima, Thomas Charles Sternweiler, Matthew J. Fitz

Patent number: 9539122Abstract: An apparatus for treating vascular aneurysms includes an occlusive support device comprised of one or more support members. The occlusive device has, an end cap member and an anchoring member. The end cap member is comprised of at least one of one or more of the support members. The end cap member has openings and the end cap member comprises a reactive material that is configured to hydrate upon delivery of the device and to reduce the size of said openings. The device is configured so that the occlusive members can be positioned in the blood vessel proximate the neck of a vascular aneurysm, the reactive material hydrates and increases the resistance to blood flow into the aneurysm, and the anchoring member anchors the device in the blood vessel without occluding flow through the blood vessel.Type: GrantFiled: March 24, 2014Date of Patent: January 10, 2017Assignee: MicroVention, Inc.Inventors: Thomas H.

Publication number: 20160242893Abstract: A stent utilizing an integral filter is described. The filter portion of the stent can be connected directly to the end of the stent or can be space apart via a plurality of struts.

Publication number: 20160206322Abstract: An implantable embolic device having a stretch-resistant member passing therethrough that also serves as a tether for connecting the device to a delivery system. The stretch-resistant member is attached at a proximal and distal end of the device and extends proximally to the delivery device. The proximal attachment point serves to isolate a distal, stretch resisting segment of the member from axial tension placed on a proximal, connecting section of the member. Thus, the portion of the stretch-resistant member being used to connect the embolic device to a delivery device may be placed under tension without placing tension or distorting the implant.Type: ApplicationFiled: March 25, 2016Publication date: July 21, 2016Applicant: MicroVention, Inc.Inventors: Matthew J. Fitz, Cathy Lei, Joseph Gulachenski, Maricruz Castaneda, Gary Currie

Publication number: 20090082843Abstract: The invention is directed to a self-expanding stent for implantation into a body lumen, such as an artery. The stent consists of a plurality of radially expandable cylindrical elements generally aligned on a common longitudinal stent axis and interconnected by a plurality of interconnecting members placed on the stent in a collinear arrangement such as to create at least one continuous spine which extends along the length of the stent. The invention is also directed to a stent delivery system for implantation of a stent in a vessel which includes an outer tubular member having a restraining sheath and an inner tubular member having a distal end which has a compressed stent mounted thereto. The proximal end of the inner tubular member is connected to a housing assembly which prevents the inner tubular member from moving when the outer tubular member is retracted to deploy the stent.Type: ApplicationFiled: September 25, 2008Publication date: March 26, 2009Applicant: ADVANCED CARDIOVASCULAR SYSTEMS, INC.Inventors: Daniel L.
