Patent number: 11382816Abstract: Embodiments disclosed herein concern a distraction system for use with a surgical table having a table portion and a base portion. The distraction system includes a pair of arms rotatably connectable to the base portion at a proximal end portion of each arm. A pair of telescopically adjustable support posts extend upwardly from corresponding arms. Each arm rotates about a vertically oriented axis to provide for hip adduction and abduction of a patient's leg. Each support post extends from a linear bearing attacked to the corresponding one of the pair of arms for movement along the arm to facilitate applying traction to a patient's leg. The system can also include a table extension attachable to the table portion and a friction pad mounted on the table extension.Type: GrantFiled: June 6, 2016Date of Patent: July 12, 2022Assignee: Stryker CorporationInventors: Robin Shandas, Omer Yehezkel Mei-Dan, Jacob Segil, Jennifer Wagner

Patent number: 10624730Abstract: Formulations of shape memory polymer (SMP) are integrated with several existing clinically available medical fabrics. The SMP portion of a SMP-integrated fabric can be fabricated in varying thicknesses with the minimum thickness determined by the thickness of the underlying fabric and up to almost any thickness. Integration of the SMP with the base fabrics does not alter the shape memory functionality of the SMP. The design tools for controlling activation rate for traditional SMP materials thus apply to SMP-integrated fabrics. SMP-integrated fabrics may also be steam sterilized without loss of shape memory functionality.Type: GrantFiled: November 20, 2017Date of Patent: April 21, 2020Assignee: THE REGENTS OF THE UNIVERSITY OF COLORADO, A BODY CORPORATEInventors: Robin Shandas, Michael Zimkowski

Patent number: 10286106Abstract: A shape memory polymer (SMP) intraocular lens may have a refractive index above 1.45, a Tg between 10° C. and 60° C., inclusive, de minimis or an absence of glistening, and substantially 100% transmissivity of light in the visible spectrum. The intraocular lens is then rolled at a temperature above Tg of the SMP material. The intraocular device is radially compressed within a die to a diameter of less than or equal to 1.8 mm while maintaining the temperature above Tg. The compressed intraocular lens device may be inserted through an incision less than 2 mm wide in a cornea or sclera or other anatomical structure. The lens can be inserted into the capsular bag, the ciliary sulcus, or other cavity through the incision. The SMP can substantially achieve refractive index values of greater than or equal to 1.45.Type: GrantFiled: May 17, 2016Date of Patent: May 14, 2019Assignee: The Regents of the University of ColoradoInventors: Malik Y.

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.
