Publication number: 20150188023Abstract: The present disclosure provides a device having a circuit. The circuit includes at least one boost converter receiving power from an energy source, a square wave driver in series with the boost converter, an inductor in series with the square wave driver for converting a square wave to a sinusoidal wave, and a piezoelectric transducer in series with the inductor, the piezoelectric transducer connectable to a load. The device further includes a phase-locked loop coupled to the circuit to determine a resonance frequency of the piezoelectric transducer when the piezoelectric transducer is connected to the load.Type: ApplicationFiled: December 29, 2014Publication date: July 2, 2015Applicant: InterMed, Inc.Inventors: Gary J. Pond, John Baeten, Michael W. Allen

Patent number: 5695482Abstract: A unitary, flexible, substantially noncollapsible catheter tube of biocompatible material is comprised of hard and soft regions. The hard regions can be ring shaped or helical. The hard regions provide sufficient rigidity to the tube to prevent collapse under normal usage as the interior and exterior pressures vary. The soft regions provide sufficient flexibility to allow contoured placement of the tube. The hard regions can be created by exposing a polymer in the tube to radiation. The hard regions can also be created by periodically adding a harder material to the tube.Type: GrantFiled: June 15, 1994Date of Patent: December 9, 1997Assignee: InterMED, Inc.Inventor: Antoine Kaldany

Patent number: 4030142Abstract: An occluder for a prosthetic heart valve assembly adapted within a seating-ring passage having a body including a downstream sealing section comprising a plurality of cuspids which engage each other to define a closed sealing section when the occluder is in its closed position and which flex outwardly relative to each other when the occluder is in its open position to define a central open passage through the occluder, and an armature reinforcing the body. The armature includes an annular ring and a plurality of reinforcing arms hingedly connected to the ring and extending through each cuspid to permit flexure of each arm relative to the annular ring.Type: GrantFiled: March 26, 1976Date of Patent: June 21, 1977Assignee: InterMed, Inc.Inventor: Gerald W.
