  • Vascular needle
    Patent number: 6921387
    Abstract: A hollow medical needle having a bevel face defining a needle tip and cutting surface that create a first incision. The needle additionally has a separate cutting blade extending outward from the needle. The blade is positioned adjacent the bevel face to create a second incision which intersects the first incision made by the bevel face cutting surface.
    Type: Grant
    Filed: May 1, 2002
    Date of Patent: July 26, 2005
    Assignee: Mayo Foundation for Medical Education and Research
    Inventor: Allan R. Camrud
  • Multi-section stent
    Publication number: 20040167616
    Abstract: A stent includes a first stent section, a second stent section, and at least one connecting member. The connecting member has a first end attached to the first stent section, a second end attached to the second stent section and a physically separable portion.
    Type: Application
    Filed: February 24, 2004
    Publication date: August 26, 2004
    Applicant: Mayo Foundation for Medical Education and Research, a Minnesota corporation

  • Stent treatment apparatus and method
    Patent number: 6709449
    Abstract: Manual stent manipulation before implantation results in foreign body contamination and increased neointimal hyperplasia. Rinsing commercially available sterile stents with high pressure immediately before implantation eliminates residual surface stent contaminants and reduces inflammation elicited by stent struts. Ex-vivo stent expansion and surface analysis revealed that rinsed stents had fewer surface contaminants than untouched or handled stents. In a porcine stent restenosis model, rinsed stents elicited less inflammation and less neointimal hyperplasia at one month than handled and untouched stents. Pressure-rinsing of coronary stents immediately before implantation reduces inflammation and neointimal hyperplasia.
