  • Patent number: 7087577
    Abstract: An angiogenic factor comprising a mixture of proteins derived from bone. The angiogenic protein mixture is produced by a series of steps that allow the proteins to be kept in solution. The angiogenic mixture of bone proteins is produced by a multi-step process that includes at least one ultrafiltration step, an anion exchange chromatography step, a cation exchange chromatography step and a high performance liquid chromatography (HPLC) purification step.
    Type: Grant
    Filed: December 22, 2000
    Date of Patent: August 8, 2006
    Assignee: Zimmer OrthoBiologies, Inc.
    Inventors: James J. Benedict, John P. Ranieri, Marsha L. Whitney, Rama Akella
  • Publication number: 20060165752
    Abstract: Stents with coatings comprising a combination of a restenosis inhibitor comprising an HMG-CoA reductase inhibitor and a carrier. Also provided are methods of coating stents with a combination of an HMG-CoA reductase inhibitor and a carrier. A preferred example of a restenosis inhibitor is cerivastatin. The stent coatings have been shown to release restenosis inhibitors in their active forms.
