Patent number: 8795345Abstract: A device including a self-expandable member having a proximal end portion, a main body portion and a distal end portion. Each of the self-expandable portions consists of a plurality of cell structures formed by intersecting strut members. In one implementation, at least one proximal cell structure in the proximal end portion has one or more struts that have a width and/or thickness greater than the width and/or thickness of the majority of strut members in the main body and distal end portions of the expandable member. Attached to at least one of the proximal-most cell structures in the proximal end portion is a proximally extending flexible wire having sufficient length and flexibility to navigate the tortuous vasculature of a patient. In another implementation, the device is delivered to the treatment site through the lumen of a delivery catheter.Type: GrantFiled: October 5, 2009Date of Patent: August 5, 2014Assignee: Concentric Medical, Inc.Inventors: Ryan M.

Patent number: 8579915Abstract: The present invention provides an obstruction removing device and a method for making the obstruction removing device. The method includes two mandrels with an elongate element being wound around the first mandrel and then wrapped around the second mandrel. The mandrels are movable relative to one another so that the second mandrel may be moved closer to the first mandrel after winding the element around the first mandrel and before winding the element around the second mandrel.Type: GrantFiled: January 17, 2012Date of Patent: November 12, 2013Assignee: Concentric Medical, Inc.Inventors: Ron French, Scott Wilson, Neil Barman, Emily Vu, John Miller

Publication number: 20130268050Abstract: The present invention is directed to methods and devices for accessing a cerebral vessel. The system includes a support catheter, which can be advanced into small and tortuous vessels. By advancing the support catheter nearer to the obstruction then can be achieved with conventional guide catheters, the support catheter reduces the likelihood vessel compression and collapse when manipulating a working catheter.Type: ApplicationFiled: May 28, 2013Publication date: October 10, 2013Applicant: CONCENTRIC MEDICAL, INC.Inventors: Scott Wilson, John Miller, Emily Vu

Patent number: 8357178Abstract: A clot retrieval device including a self-expandable member having a proximal end portion and a main body portion. The self-expandable member is expandable from a first delivery position to a second placement position. In the first delivery position the expandable member has a first overall diameter In one implementation the cell structures that form the self-expandable member have dimensional and material characteristics that result in about a ?1.0N to about a ?1.7N overall reduction in radial force along the length of the expandable member per millimeter of expansion during about an initial 0.50 mm diametric range of expansion from the first overall diameter and that results in about a ?0.10N to about a ?0.35N overall reduction in radial force along the length of the expandable member per millimeter of expansion during subsequent diametric ranges of expansion.Type: GrantFiled: July 8, 2010Date of Patent: January 22, 2013Assignee: Concentric Medical, Inc.Inventors: Ryan M.
