Abstract: Reduced odor or odorless antimicrobial phenolic compositions containing collagen amino acids and methods of use are disclosed. The compositions can be formulated for use as a soap, emollient or hard surface cleaner. In one particularly advantageous embodiment, a composition of the invention is formulated as an antimicribial cleaner including an amount of collagen amino acids sufficient to decrease the odor of the phenolic compound below its initial levels and an amount of at least one of a soap or hard surface cleaner.

Abstract: The present invention provides an improved stent delivery catheter. The stent delivery system comprises a catheter with a retractable sheath arranged concentrically near its distal end. The retractable sheath is connected to a pull wire for retraction. A sliding seal connects the proximal end of the retractable sheath and the catheter. This seal forms a fluid tight chamber when the retractable sheath is in the unretracted position, allowing the delivery system to be prepared by filling the fluid tight chamber with fluid to flush out air prior to insertion into the vasculature of the patient.
