Patent number: 5733313Abstract: The implantable, electrically operated medical device system comprises an implanted radio frequency (RF) receiving unit (receiver) incorporating a back-up rechargeable power supply and an implanted, electrically operated device, and an external RF transmitting unit (transmitter). RF energy is transmitted by the transmitter and is coupled into the receiver which is used to power the implanted medical device and/or recharge the back-up power supply. The back-up power supply within the receiver has enough capacity to be able to, by itself, power the implanted device coupled to the receiver for at least 24 hours during continual delivery of medical therapy. The receiver is surgically implanted within the patient and the transmitter is worn externally by the patient. The transmitter can be powered by either a rechargeable or non-rechargeable battery. In a first mode of operation, the transmitter will supply power, via RF coupled energy, to operate the receiver and simultaneously recharge the back-up power supply.Type: GrantFiled: August 1, 1996Date of Patent: March 31, 1998Assignee: Exonix CorporationInventors: Francisco Jose Barreras, Sr., Oscar Jimenez

Patent number: 5445624Abstract: The present invention relates to an improved intravascular catheter. The intravascular catheter involves the use of a progressively compliant tip at the distal end of the catheter body. This progressively compliant tip utilizes an endmost tubular member having a first softness and an intermediate tubular member having a second softness. The low temperature thermoplastic overcoat on the catheter body has a third softness which is significantly lower than the first and second degrees of softness exhibited by the other tubular members. The endmost member, intermediate member and thermoplastic overcoat are joined together by heat formed, blended tubular regions, each having respective incrementally increasing intermediate softness characteristics over predetermined lengths thereof.Type: GrantFiled: January 21, 1994Date of Patent: August 29, 1995Assignee: Exonix Research CorporationInventor: Oscar Jimenez
