Abstract
Embodiments 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 embodiments 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 embodiments can include a sheath with an intermediate layer including an expandable mesh tube, an outer polymeric layer extending over at least a portion of the intermediate layer, and an inner polymeric layer extending within the intermediate layer. The intermediate layer and the inner polymeric layer are configured to establish an enlarged lumen to allow passage of the prosthetic heart valve.
