  • Catheter device and method of use for intramural delivery of protein kinase C and tyrosine protein kinase inhibitors to prevent restenosis after balloon angioplasty
    Patent number: 5242397
    Abstract: The present invention discloses a method of treatment of an atherosclerotic blood vessel. Protein kinase C and tyrosine protein kinase inhibitors are delivered by means of a specialized catheter system to the deeper layers of the vessel wall with only minimal interruption of the vessel endothelium. This system will allow high local concentrations of otherwise toxic agents directly at the site of an atherosclerotic plaque to prevent and/or reduce the incidence of late restenosis attributed to cellular hyperplasia or rethrombosis.
    Type: Grant
    Filed: January 2, 1992
    Date of Patent: September 7, 1993
    Assignee: Cedars-Sinai Medical Center

  • Catheter device for intramural delivery of therapeutic agents
    Patent number: 5112305
    Abstract: The present invention discloses a method of treatment of an atherosclerotic blood vessel. Specifically, therapeutic agents are delivered by means of a specialized catheter system to the deeper layers of the vessel wall with only minimal interuption of the vessel endothelium. This system will allow high local concentrations of otherwise toxic agents directly at the site of an atherosclerotic plaque. This invention will hopefully reduce the incidence of late restenosis attributed to cellular hyperplasia or rethrombosis.
