摘要： An introducer sheath assembly having an improved valve assembly including at least three elastic disc shaped membranes. A first membrane has a circular hole through the center to sealingly receive a catheter while a second membrane has a center hole smaller than the hole in the first membrane to sealingly receive a guidewire. The second membrane also has at least one slit through the hole to accommodate passage of the larger catheter through the second membrane. A third membrane contains at least one slit through its center to seal the valve assembly in the absence of a guidewire or catheter.

摘要： According to one embodiment of the invention, a system for removing a cover from a medical instrument includes a flexible cover configured to cover at least a portion of a medical instrument, an insertion element coupled proximate a first end of the flexible cover, a pair of substantially parallel perforations formed in the insertion element, a pair of substantially parallel score lines formed in the cover and aligned with the pair of substantially parallel perforations. A portion of the insertion element between the pair of substantially parallel perforations is removable from the insertion element and a portion of the flexible cover between the pair of substantially parallel score lines is removable from the flexible cover when a force is applied to the portion of the insertion element between the pair of substantially parallel perforations.
