Publication number: 20210369915Abstract: Artificial cartilage materials for repair and replacement of cartilage (e.g., load-bearing, articular cartilage). The artificial cartilage materials described herein include triple-network hydrogels including a cross-linked fiber network (e.g., a bacterial cellulose nanofiber network) and a double-network hydrogel (e.g., a double-network hydrogel including polfacrylamide-methyl propyl sulfonic acid). The artificial cartilage may be coated onto or formed into an implant (e.g., plug). The artificial cartilage may include a surface macroporosity, e.g., 0.1-300 micrometers diameter. Also described herein are methods of forming and methods of using the triple-network hydrogel artificial cartilage materials.Type: ApplicationFiled: November 7, 2018Publication date: December 2, 2021Inventors: Benjamin Wiley, Feichen Yang, Kenneth Gall, Jonathan Riboh

Patent number: 9731045Abstract: A polymer is composed of a linear chain acrylate and a multi-functional acrylate cross-linker. The polymerized composition exhibits a transition at a temperature between about 34° C. and about 50° C. The polymerized composition exhibits shape memory effects. In one embodiment, the linear chain is tert-butyl acrylate and the crosslinker is polyethylene glycol dimethacrylate. The resultant shape memory polymers may be used in medical devices to provide devices with different shapes for pre and post implantation.Type: GrantFiled: January 6, 2014Date of Patent: August 15, 2017Assignee: THE REGENTS OF THE UNIVERSITY OF COLORADOInventors: Kenneth Gall, Christopher Yakacki

Patent number: 8952634Abstract: A synchrocyclotron comprises a resonant circuit that includes electrodes having a gap therebetween across the magnetic field. An oscillating voltage input, having a variable amplitude and frequency determined by a programmable digital waveform generator generates an oscillating electric field across the gap. The synchrocyclotron can include a variable capacitor in circuit with the electrodes to vary the resonant frequency. The synchrocyclotron can further include an injection electrode and an extraction electrode having voltages controlled by the programmable digital waveform generator. The synchrocyclotron can further include a beam monitor. The synchrocyclotron can detect resonant conditions in the resonant circuit by measuring the voltage and or current in the resonant circuit, driven by the input voltage, and adjust the capacitance of the variable capacitor or the frequency of the input voltage to maintain the resonant conditions.Type: GrantFiled: October 22, 2009Date of Patent: February 10, 2015Assignee: Mevion Medical Systems, Inc.Inventors: Alan Sliski, Kenneth Gall
