  • 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
    Inventors: Peter Barath, Ferenc Denes
  • 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.

  • Process for the preparation of aluminum oxide carboxylate polymers containing at most two percent by weight of ester
    Patent number: 5075473
    Abstract: The invention relates to a novel process for the preparation of aluminum oxide carboxylate polymers containing at most 2% by weight of ester by reacting an aluminum alkoxide of the general formula Al(OR).sub.3, wherein R stands for a C.sub.2-5 alkyl group, dissolved in an aromatic or aliphatic hydrocarbon with a solution of a C.sub.8-22 aliphatic or alicyclic monocarboxylic acid or carboxylic acid mixture and water in a C.sub.2-5 alkanol and removing the alkanol(s).The process according to the invention comprises introducing the solution of the aluminum alkoxide to a tube reactor having a 10 to 200 length/diameter ratio at a temperature exceeding by 15.degree.to 50.degree.C.
