US Patent:

20050283256, Dec 22, 2005

Filed:

Jun 30, 2005

Appl. No.:

11/171638

Inventors:

Robert Sommerich - Norton MA, US
Laurel Macomber - North Attleboro MA, US

Assignee:

CODMAN & SHURTLEFF, INC. - Raynham MA

International Classification:

A61F002/02

US Classification:

623023740

Abstract:

A laminated, bioimplantable dural graft product is configured for use as both an onlay graft and a suturable graft. The dural graft product is sufficiently pliable so as to sufficiently conform to a curvature of a tissue surface to which it is applied, such as the curved surface of a meningeal membrane. The use of the graft product can have improved properties, including suture retention strength and fluid impermeability. To use the dural graft product as an implant to replace, reinforce or strengthen bodily tissue, or to act as an adhesion barrier, the dural graft is placed in contact with bodily tissue and conforms to the curvature of the bodily tissue. Sutures can be used to maintain the contact between the dural graft and the bodily tissue.

Abstract:

A collagen device is prepared by mixing collagen with purified water for a period of time sufficient to form a mixture. The pH of the mixture is adjusted to a pH level sufficient to substantially solubilize the collagen. A first predetermined amount of the mixture is placed into a container. The mixture is subject to a lyophilizing process and formed into a collagen device. The collagen device is also cross-linked. The collagen device has a plurality of pores wherein a majority of the pores have a diameter of less than 10 μm. To use the collagen device as an implant to replace, reinforce or strengthen bodily tissue, or to act as an adhesion barrier, the collagen device is placed in contact with bodily tissue and that contact is maintained until the collagen device is substantially resorbed within the bodily tissue.
