Abstract: Aspects of an expandable sheath can be used in conjunction with a catheter assembly to introduce a prosthetic device, such as a heart valve, into a patient. Such aspects can minimize trauma to the vessel by allowing for temporary expansion of a portion of the introducer sheath to accommodate the delivery apparatus, followed by a return to the original diameter once the prosthetic device passes through. Some aspects can include a sheath with inner and outer layers having at least one folded portion of the inner liner. Some aspects include the inner liner having etched, unetched, and otherwise surface-modified portions. Aspects of the present expandable sheath can avoid the need for multiple insertions for the dilation of the vessel, thus offering advantages over prior art introducer sheaths.

Abstract: An introducer sheath system comprising including a gasket disposed around an outer surface of a dual layered sheath. The gasket providing a radially inward force on the sheath to seal the sheath an outer layer of the sheath against an inner layer to prevent fluid flow therebetween.
