Patent number: 9237958Abstract: The present invention provides an implantable joint prosthesis configured to replace a natural joint, and methods for implantation. The prosthesis may include a first component implantable in a first bone, having a first bearing surface, and a second component implantable in a second bone, having a second bearing surface which corresponds to the first bearing surface. Each bearing surface may include a flattened section such that when the bearing surfaces are placed in cooperation with one another in a preferred orientation, the flattened sections are aligned. Alternatively, the bearing surfaces may have and asymmetric configuration, with non-congruent surfaces that may enable correction of deformity. Several types of implantable joint prostheses are disclosed, including: carpometacarpal, metacarpophalangeal, metatarsophalangeal, distal interphalangeal, proximal interphalangeal, ankle, knee, shoulder, and hip.Type: GrantFiled: March 4, 2008Date of Patent: January 19, 2016Assignee: Synergy Disc Replacement Inc.Inventors: Neil A Duggal, Louise C.

Patent number: 8992568Abstract: A system and method for treating a defect. The system may comprise a first expandable barrier insertable into a defect interior space in a compact state and then expanded once positioned inside the defect. The first expandable barrier is expanded to be positioned against the inner surface of the defect. The system may also comprise a second barrier which may be expandable, positioned against the outer surface of the defect. Each of the first and second barriers may expand laterally to a greater extent than axially. The first and second barriers may be in communication through a connection member which couples the two barriers together. The barriers each obliterate the defect and can prevent subsequent CSF or other fluid leaks. Fibrin glue may be introduced into the defect to seal and secure the barriers to the defect. Each barrier may comprise a mesh, a basket, an umbrella or a balloon.Type: GrantFiled: October 20, 2009Date of Patent: March 31, 2015Inventors: Neil Duggal, Louise C. Raymond, Joshua A. Butters

Patent number: 8894709Abstract: The present invention provides artificial disc prostheses, methods and instrumentation for implantation and revision thereof. Each prosthesis may comprise superior and inferior end plates and a nucleus positioned between articular surfaces of the end plates. The end plates may have planar bone engagement surfaces with a plurality of self-cutting teeth. The articular surfaces of the end plates may be planar or include a flattened portion. The nucleus includes superior and inferior articular surfaces which may comprise flattened portions such that when the articular surfaces of the nucleus and the end plates are placed in cooperation in a preferred orientation, the flattened and/or planar portions are aligned. Each prosthesis may provide flexion/extension, anterior/posterior translation, lateral bending, and/or axial rotation degrees of freedom.Type: GrantFiled: October 27, 2008Date of Patent: November 25, 2014Assignee: Synergy Disc Replacement, Inc.Inventors: Neil Duggal, Louise C. Raymond, Joshua A. Butters, Jeffery D. Arnett, Dylan M. Hushka

Publication number: 20130238083Abstract: A system for treating an aneurysm includes an expandable barrier positionable to bridge an aneurysm neck. The barrier may comprise a fiber mesh, a balloon or a molly anchor member, and may unroll, unfold, or inflate from a compact configuration to an expanded configuration. Expansion of the barrier may be greater radially than axially. A vaso-occlusive member comprising a coil or balloon may be deposited in the aneurysm. Another aneurysm treatment system comprises an outer fenestrated stent and/or an inner fenestrated sleeve, which may be implanted together adjacent an aneurysm neck to regulate blood flow to the aneurysm. The sleeve may be movable relative to the stent to open or occlude the fenestrations, which may vary in size, shape, and distribution. An intra-luminal vessel occlusion device comprises a stent and a sheath. A drawstring may be actuated to gradually close a sheath orifice to control blood flow through the vessel.Type: ApplicationFiled: April 25, 2013Publication date: September 12, 2013Applicants: IMDS CorporationInventors: Neil Duggal, Robert De Hoog, Donald Heaton Lee, Louise C. Raymond, Joshua A. Butters
