Patents by Inventor Kalpana R. Kamath

Kalpana R. Kamath 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).

  • Patent number: 7906133
    Abstract: The inventors have found that both the drug dose and drug release profiles are significant factors for the safety and efficacy of drug coated stents. The inventors have identified optimum dosing and release kinetics for drug coated stents. In particular, the inventors have determined dosing and release kinetics that permit the delivery of the lowest effective drug dosage, thus enhancing patient safety and minimizing any side effects from the drug.
    Type: Grant
    Filed: May 11, 2005
    Date of Patent: March 15, 2011
    Assignee: Boston Scientific Scimed, Inc.

  • Patent number: 6589546
    Abstract: Implantable medical device having a structure adapted for introduction into a patient wherein the structure is composed of a base material positioned over the structure. The implantable medical device further includes at least one composite layer of a bioactive agent and a polymer material and at least a barrier layer positioned over the composite layer and being of thickness adequate to provide a controlled release of the bioactive agent. The barrier layer being applied by a low energy plasma polymerization process which includes placing the device with the at least one composite layer in a plasma chamber and introducing at least one monomer gas.

  • Patent number: 5376692
    Abstract: A medical device has one or more polymeric substrates each treated with a chemically binding coating to make each polymeric substrate compatible for contact with blood. A modified natural and substantially hydrophilic blood protein bonds permanently to each substrate. The protein is functionalized with bonding sites so after application thereof to each substrate and if subject to sufficient radiation, free radicals created on each substrate and the functionalized protein chemically bind. A modifier added to the protein creates sites by functionalizing it before application to each substrate. The functionalized combination is applied to each substrate. The protein is human or animal albumin as bovine.The modifier are molecules having an epoxy function for attachment to the human or animal albumin. An unsaturated double bond forms or accepts free radicals at bonding sites. The modifier added to the protein is glycidyl acrylate.
