Patents by Inventor Alexander W. Clowes

Alexander W. Clowes 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).

  • Publication number: 20040191253
    Abstract: Methods for inhibiting intimal hyperplasia in the vasculature of mammals, including primates, are disclosed. The methods comprise administering to the mammal an anti-PDGF receptor antibody, such as an anti-PDGF-alpha receptor antibody or an anti-PDGF-beta receptor antibody. The methods are useful in reducing intimal hyperplasia due to, for example, vascular injuries resulting from angioplasty, endarterectomy, reduction atherectomy or anastomosis of a vascular graft. The anti-PDGF receptor antibodies may optionally be administered coordinately with heparin, whereby the coordinately administered antibody and heparin are combinatorially effective in inhibiting intimal hyperplasia.

  • Publication number: 20040156833
    Abstract: Vascular grafts are used in gene therapy to implant autologous vascular smooth muscle cells that have been transduced with the gene of interest. The smooth muscle cells are immobilized within the pores and upon the interior surface of the wall of the graft, which is then coated with vascular endothelial cells and implanted into a patients's vascular system. The grafting device can be used in methods of treatment, such as supplying erythropoietin to a patient, and can be removed easily and replenished as necessary. The process is readily controlled and significantly reduces the risk of a viral gene vector spreading beyond a target cell population.
