Patent number: 11964129Abstract: In various embodiments, a drug pump includes a housing and, within the housing, an expandable drug reservoir at least part of which is exposed to a pressurized propellant. The propellant exerts a substantially constant pressure on the drug reservoir. A flow restrictor significantly limits outflow from the pump, and preferably has both a small diameter and a long path length, which acts to control the outflow from the drug reservoir. As a result, the pump produces a substantially constant outflow.Type: GrantFiled: March 1, 2019Date of Patent: April 23, 2024Assignee: MiniPumps LLCInventors: Jason Shih, Gregory Harbers, Richard Purvis, Miho Matsuoka, Andrew Urazaki, Mark Humayun, William Andrew Brandt, Atoosa Lotfi, Didier Sagan, Andrew Dunn

Patent number: 10827936Abstract: A method for forming an implantable electrode (100) includes exposing a conductive surface of the electrode (100) with a first application of an excimer laser (215) and creating a first surface texture on a conductive surface with a second application of the excimer laser. In one example, a low impedance implantable electrode includes a conductive surface and a coating disposed over the conductive surface. The coating may have a lower contact impedance with biological tissue than the conductive surface. At least a portion of the coating has an excimer laser textured surface.Type: GrantFiled: August 15, 2013Date of Patent: November 10, 2020Assignee: Advanced Bionics AGInventor: Atoosa Lotfi

Patent number: 10240689Abstract: Microscale valves for use in, e.g., micropump devices, may be formed of a slitted diaphragm bonded o the interior of a valve tube. A bump in the diaphragm and/or a backward-leakage stopper may increase the breakdown pressure of the valve. A push-rod may be used to pre-load the valve membrane to thereby increase the cracking pressure.Type: GrantFiled: November 7, 2017Date of Patent: March 26, 2019Assignee: MINIPUMPS, LLCInventors: Yu-Chong Tai, Po-Ying Li, Fukang Jiang, Changlin Pang, Natasha Yvette Bouey, Man Ting Chou, Atoosa Lotfi

Publication number: 20170143873Abstract: A method for sterile packaging of a surface modified implantable device includes irradiating a surface of the device such that the hydrophobicity of the surface is decreased and, optionally, the device is simultaneously sterilized. The surface of the sterile, surface-modified implantable device is then covered in a polar solution to prevent hydrophobic recovery of the surface.Type: ApplicationFiled: February 8, 2017Publication date: May 25, 2017Applicant: Advanced Bionics AGInventor: Atoosa Lotfi

Patent number: 9263172Abstract: A method for forming a wire construct includes forming a groove in a polymer having a mouth that is narrower than a width of a deeper portion of the groove and placing a substantial length of wire in the groove, the wire having a larger cross-sectional dimension than the mouth of the groove. Encapsulant is placed over the polymer. The wire construct is to be used for implantable stimulation leads, such as a cochlear stimulation lead or a neurostimulation lead. Two wire constructs can be assembled to form a multilayer wire construct.Type: GrantFiled: February 16, 2012Date of Patent: February 16, 2016Assignee: ADVANCED BIONICS AGInventor: Atoosa Lotfi

Publication number: 20150365738Abstract: In various embodiments, a system for receiving wireless power includes a magnetic core and a plurality of layers of unbraided electrical conductors wrapped around the magnetic core. Each unbraided electrical conductor includes a first endpoint and a second endpoint; the first endpoint and the second endpoint are electrically connected to a circuit to provide power thereto, and two of the unbraided electrical conductors are electrically insulated from each other between the first endpoint and the second endpoint. The system may include a biocompatible, magnetically transparent, rigid polymer casing surrounding the magnetic core and at least a portion of the electrical conductors.Type: ApplicationFiled: August 5, 2015Publication date: December 17, 2015Inventors: Rick Purvis, William Andrew Brandt, Atoosa Lotfi, Didier Sagan, Fukang Jiang, Greg Harbers, Brett Daniel Schleicher, Nenad Jelisavcic, Yu-Chong Tai, Faysal Ahmed, Rudy Montalvo, Tuan Pham, Steven Arroyo

Publication number: 20150105864Abstract: The invention provides a biocompatible silicone implant that can be securely affixed to living tissue through interaction with integral membrane proteins (integrins). A silicone article containing a laser-activated surface is utilized to make the implant. One example is an implantable prosthesis to treat blindness caused by outer retinal degenerative diseases. The device bypasses damaged photoreceptors and electrically stimulates the undamaged neurons of the retina. Electrical stimulation is achieved using a silicone microelectrode array (MEA). A safe, protein adhesive is used in attaching the MEA to the retinal surface and assist in alleviating focal pressure effects. Methods of making and attaching such implants are also provided.Type: ApplicationFiled: September 28, 2014Publication date: April 16, 2015Inventors: Adrian P. Rowley, Lucien D. Laude, Mark S. Humayun, James D. Weiland, Atoosa Lotfi, Francis S. Markland, Jr.
