John T. Sylvanowicz has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Self-sealing guidewire and catheter introducer
    Patent number: 5702370
    Abstract: A self-sealing catheter and guidewire introducer has a self-sealing gasket adapted to effect a seal when a catheter or guidewire extends through the gasket as well as when neither extends through the gasket.
    Type: Grant
    Filed: April 18, 1994
    Date of Patent: December 30, 1997
    Assignee: C. R. Bard, Inc.
    Inventors: John T. Sylvanowicz, George W. Bourne, IV

  • Variable shaped catheter system and method for catheterization
    Patent number: 5267982
    Abstract: A catheter assembly and method for catheterization provides a means by which the curved configuration at the distal portion of a catheter can be varied while the catheter system remains in the patient. The catheter, having a predetermined curve at its distal end is received within a sheath that can be advanced over the distal end to tend to straighten the curve in the distal end of the catheter. The extent to which the sheath is advanced over the curved distal portion of the catheter controls the degree to which the catheter is straightened. The position of the sheath relative to the catheter can be adjusted while the catheter is in the patient, thereby enabling change in catheter shape without requiring catheter exchanges. For example, the system enables right and left coronary angiographic procedures to be performed without changing catheters. Left ventricular studies also can be made without catheter exchanges.
