Patent number: 10000605Abstract: A three-dimensional smart polymer matrix is formed by a first epoxy chemical reaction linking a linear polymer chain and a branched polymer chain, wherein the polymer chains are flexible and one or more reactive molecule species remain unreacted, at a predetermined mathematical ratio of reacted to un-reacted molecules and molecule species, and the un-reacted molecular species are available for further chemical reaction, protonation or deprotonation after the first chemical reaction. The resulting smart polymer matrix is hydrophilic and non-soluble to a solvent or electrolyte.Type: GrantFiled: March 13, 2013Date of Patent: June 19, 2018Assignees: MEDIPACS, INC., THE ARIZONA BOARD OF REGENTS ON BEHALF OF THE UNIVERSITY OF ARIZONAInventors: Mark Banister, Yordan Geronov, Dominic McGrath

Patent number: 9995295Abstract: A device for metering fluids comprising a fluid chamber with one inlet or outlet port, at least one sidewall and a movable separator that is in contact with and separates the fluid in the chamber from the other components of the device, a porous actuator housing and wicking material, a flexible polymer actuator material in contact with the porous actuator housing and the moveable separator, an actuator hydrating solution reservoir with at least one sidewall, an inlet port, and in fluid contact with porous actuator housing, a fluid gate located at some point between actuator hydrating solution reservoir and the polymer actuator, effectively keeping actuator dry, and an external shell to hold all components so that the polymer actuator can only move in a direction and apply pressure to the separator in contact with the fluid in the fluid chamber, thereby dispensing fluid from fluid chamber.Type: GrantFiled: December 3, 2008Date of Patent: June 12, 2018Assignee: MEDIPACS, INC.Inventors: Mark Banister, Dale L. Fanter

Patent number: 9039389Abstract: A pump system containing no external parts or valves is provided. The pump system is characterized by a common type of actuating mechanism and incorporates reversibly expanding actuators, preferably electroactive actuators. Fluid is caused to move at a selected flow rate and direction by sequentially activating contiguous actuators located inside the pump. The pump may be used to pump a variety of fluids and may be used in various industrial, commercial, medical, aeronautical, or military applications.Type: GrantFiled: November 4, 2013Date of Patent: May 26, 2015Assignee: MEDIPACS, INC.Inventor: Mark Banister

Publication number: 20140221913Abstract: A low profile and volumetrically efficient medication delivery device configured to be placed on the body of a patient during fluid delivery to the patient is provided. The device incorporates a low profile actuator assembly that causes fluid delivery by displacing a collapsible reservoir in response to receiving an electrical current or charge input from a programmable controller and a power supply. Additional components help prevent drug theft or abuse, measure actuator pressure, displacement and temperature in real time providing active feedback to the controller that is controlling the actuator. The device also has wireless communication capabilities.Type: ApplicationFiled: September 25, 2012Publication date: August 7, 2014Applicant: Medipacs, Inc.Inventors: Mark Banister, Raymond Clark, Erich Coiner, Yordan M. Geronov, Mark D. McWilliams, Ralph Sias, Mark Van Veen, Gary Walters
