Patent number: 9498586Abstract: An infusion pump system including an infusion tubing for delivering a fluid, a heat exchanger cartridge in fluid communication with the infusion tubing and removably coupled to at least one thermal element for heating or cooling the fluid, a motor driven pump in mechanical communication with the infusion tubing and configured to pump the fluid through the infusion tubing and the heat exchanger cartridge, and a central controller in electrical communication with the motor driven pump and the at least one thermal element. The central controller is configured to selectively deliver the fluid to a patient without heating or cooling the fluid by causing the motor driven pump to pump the fluid through the infusion tubing and the heat exchanger cartridge while the thermal element is off.Type: GrantFiled: June 30, 2014Date of Patent: November 22, 2016Assignee: SMISSON-CARTLEDGE BIOMEDICAL LLCInventors: Hugh F.

Patent number: 9084677Abstract: The present invention is directed to methods and systems for adjusting an implant, such as a mitral valve ring, over the long term without having to enter a patient's body. The long term adjustment system can include a magnet, or other magnetic material, that is functionally connected to the adjustment mechanism of an adjustable implant. The long term adjustment system can be activated by placing an activating magnet near the area of the patient's body where the adjustable implant is located and positioning the activating magnet so that an attractive force is generated between the activating magnet and the magnet that is functionally connected to the adjustable implant. Due to the attractive force between the two magnets, rotation of the magnet outside the patient's body will adjust the size and/or shape of the implant.Type: GrantFiled: July 29, 2009Date of Patent: July 21, 2015Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Richard G. Cartledge, John P. Cartledge

Patent number: 8662154Abstract: The present invention relates to a system for increasing the temperature of a fluid being infused into a patient's body while the infusion is taking place. The present invention also provides for improved monitoring of air in the infusion system such to prevent the introduction of air into the patient's body receiving the fluid infusion. The present invention also provides for a system pump which provides a variable flow rate that serves a vast amount of infusion needs and purposes. A disposable cartridge in accordance with the present invention will allow for the efficient transfer of heat energy to the fluid being infused into the patient's body. The cartridge will further ensure that deleterious amounts of air will not be introduced into the patient's body.Type: GrantFiled: June 11, 2009Date of Patent: March 4, 2014Assignee: Smisson-Cartledge Biomedical LLCInventors: Hugh F.
