Patent number: 8353814Abstract: A method for securing a compliant scaffold to an outer surface of a vascular graft includes positioning the scaffold radially about an elongated support tube which includes first and second radially outwardly flared end portions respectively defining first and second open ends of the support tube. The method further includes pulling the vascular graft through a lumen of the support tube, and axially deploying the scaffold over the first end portion of the support tube and into compliant contact with the outer surface of the vascular graft.Type: GrantFiled: October 9, 2008Date of Patent: January 15, 2013Assignee: Kips Bay Medical, Inc.Inventors: Manuel A.

Patent number: 7759099Abstract: Apparatus and methods for seeding an implantable medical device, such as a vascular prosthesis, with cells, such as endothelial cells, are described. The invention supports techniques for seeding a luminal surface of the device with axial centrifugation. Cells are introduced in suspension into the lumen of the device. The introduction of the cells may occur after a blood centrifugation product, such as platelet-poor plasma, is applied to the luminal surface. After the cells are introduced, the device is then subjected to centrifugation around a longitudinal axis defined by the lumen. Axial centrifugation causes the cells to concentrate toward and adhere to the luminal surface. Shortly after axial centrifugation, the seeded device can be presented for implantation in a patient. The implantable medical device may be inserted into a protective sleeve prior to seeding the device with cells, and the sleeve may or may not be removed prior to implantation.Type: GrantFiled: March 2, 2006Date of Patent: July 20, 2010Assignee: Kips Bay Medical, Inc.Inventors: Michael F. Wolf, Laurie A. Yunker, Paul V. Trescony
