Patent number: 7985330Abstract: A method and program prevents a user from bypassing a limit placed on a specified operating life of a sensor by disconnecting and reconnecting the sensor. The present invention checks a characteristic of the sensor to see if the sensor is used prior to the connection of the sensor, and rejects the sensor if the sensor is determined to have been used before. The process of checking the characteristic of the sensor involves performing an Electrochemical Impedance Spectroscopy (EIS) procedure and calculating an impedance value. The impedance value can be compared to various threshold values for a variety of purposes including the determination of age, condition, hydration, and stabilization of the sensor.Type: GrantFiled: December 29, 2006Date of Patent: July 26, 2011Assignee: Medtronic Minimed, Inc.Inventors: Lu Wang, Rajiv Shah, Kenneth W.

Patent number: 7912525Abstract: A method and apparatus for enhancing the integrity of an implantable sensor. Voids formed between an outer tubing and a sensor substrate or spacing element may be back-filled with a curable, implantable material, minimizing the extent to which unwanted fluids diffuse within the sensor. An enzyme or protein matrix pellet below the sensor window may be pre-treated with a reducing agent to enhance its bond stability, and to reduce undesired swelling that may cause the sensor window to detach or leak. The bonding between the enzyme pellet and a hydrogel layer may be reinforced by application of an intervening bonding layer of a protein material, such as human serum albumin (HSA). The size of the window may be minimized by minimizing the size of an underlying electrode, providing reduced flux and lengthening sensor. A coating may be deposited on the surface of the sensor leads, providing stiffening and lubrication.Type: GrantFiled: November 30, 2006Date of Patent: March 22, 2011Assignee: Medtronic Minimed, Inc.Inventors: Rajiv Shah, Yanan Zhang, Rebecca Gottlieb, Bahar Reghabi, Michael Miller
