Patent number: 10603043Abstract: An occlusion device for a vascular or biological lumen includes a plurality of coiling members held together at both the proximal and distal ends by retaining features. A restraining loop can hold coiling members together at a point along a length of the coiling members. The coiling members are delivered simultaneously to form a coil pack to occlude a target location in the lumen. One or more of the coiling members has at least a portion with a larger curl diameter than other coiling members to secure the occlusion device against lumen walls at the target location. The coil members may have different or varying material moduli. The device may be used, for example, for occluding a vessel to block blood flow to an artery supplying blood liver (hepatic artery), kidney (renal artery), spleen (splenic artery) or intestines (mesenteric artery).Type: GrantFiled: January 17, 2013Date of Patent: March 31, 2020Assignee: Endoshape, Inc.Inventors: Charles Barkenbus, Jeffrey Castleberry, Julie Trommeter, William Aldrich

Patent number: 10206685Abstract: A delivery apparatus for a lumen occlusion device includes a pusher configured for releasably coupling with and pushing and pulling a proximal end of the occlusion device in a distal or proximal direction and a distal control wire capable of releasably coupling with the distal end and the proximal end of the occlusion device. The control wire may be configured for moving the distal end of the occlusion device in both proximal and distal directions allowing precise simultaneous control of both proximal and distal ends of the occlusion device. Control of both ends provides for placing the occlusion device in tension during delivery through a delivery catheter, thereby reducing delivery forces, achieving greater compaction of the occlusion device in the lumen, and precisely locating both distal and proximal ends of the occlusion device within the lumen.Type: GrantFiled: April 14, 2016Date of Patent: February 19, 2019Assignee: ENDOSHAPE, INC.Inventors: Julie Trommeter, Charles Barkenbus, Jeffrey Castleberry, William Aldrich, Jon Page, Paul Burek, Stan Needle, Frank Becking, Dean Carson, Jessi Watson

Patent number: 9808252Abstract: Shape memory materials (SMM) are formed as coil-shaped vascular occlusion devices upon deployment. Shape memory polymer (SMP) materials are tailored through formulation for specific mechanical behavior of the coils. Concurrent coil diameter changes enhance the relative change in stiffness along the length of the coil. Interconnecting structures (104a/b) are formed on ends of elongated members (102a) in the pre-deployment shape for multiple coil insertion capability within an introducer. Channels (206) are formed in pre-deployment shape, elongate members (202) that allow access for injection of imaging contrast agent or concurrent placement of instruments. A single SMM occlusive device (300) transforms into multiple, smaller diameter coils (302b) in the deployed state to generate a complex occlusive structure.Type: GrantFiled: April 2, 2010Date of Patent: November 7, 2017Assignees: ENDOSHAPE, INC., THE REGENTS OF THE UNIVERSITY OF COLORADO, A BODY CORPORATEInventors: Julie Marie Trommeter, Michael B.
