a) Candidate Device Intended Use

The Glycar Inc., Vascular Repair Patch has the same intended uses as the predicate device, the Bio-Vascular Inc., Vascu-Guard™ family of products, which are all tissue patches made from the same glutaraldehyde-treated bovine pericardium.

Already approved intended uses for the Glycar Tissue Repair Patch family of glutaraldehyde-tanned bovine pericardial tissue patches:

The Glycar Tissue Repair Patch (K942911) was deemed substantially equivalent to the Peri-Guard™ bovine pericardial tissue patch and received approval for U.S. marketing for the intended use of hernia and other intra-abdominal soft tissue defect or deficiency repair in December, 1994.

An addition to the Glycar Tissue Repair Patch family of products, the Glycar Staple Strip (K954665) was deemed substantially equivalent to the Peri-Strips™ bovine pericardial surgical staple bolsters and received approval for U.S. marketing for the intended uses of surgical stapling of lung tissue, gastric staplings, rectal and vaginal prolapse, urethral sling, reconstruction of the pelvic floor, and hernias or defects of the diaphragm, thoracic and abdominal wall in October, 1995.

See under Indication For Use Statement.

The Glycar Staple Strip uses the identical material as the Glycar Tissue Repair Patch with the addition of a synthetic suture material to assist placement of the device on a surgical stapling arm.

See in Addenda, Chart 1, Comparison Chart, under Substantial Equivalence.
