  • Catheter having an improved balloon-to-catheter bond
    Patent number: 8449497
    Abstract: A balloon catheter assembly includes a first tubular member with a proximal portion and a distal portion and a lumen extending between the proximal portion and the distal portion. A balloon has a proximal waist length, a distal waist length and an expandable region therebetween disposed about the distal portion. A tie layer is disposed between the proximal waist length or distal waist length and the first tubular member. The tie layer comprises a polyester polymer and a polyamide polymer.
    Type: Grant
    Filed: March 28, 2011
    Date of Patent: May 28, 2013
    Assignee: Boston Scientific Scimed, Inc.
    Inventors: John Chen, Nie Tang, Ed Parsonage, Paul Miller, Lixiao Wang
  • DRUG COATED STENT WITH ENDOSOME-DISRUPTING CONJUGATE
    Publication number: 20110250255
    Abstract: A stent is provided with a drug-eluting layer disposed on at least a portion of its surface, wherein the drug-eluting layer comprises an endosome-disrupting agent and a pharmaceutical agent. In an embodiment, the endosome-disrupting agent, when taken up through endocytosis into living cells, causes lysis of endosomes containing the endosome-disrupting agent. The pharmaceutical agent can accompany the endosome-disrupting agent into the living cells.
