  • Expandable sheath for introducing an endovascular delivery device into a body
    Patent number: 12667690
    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 comprising an inner layer comprising a reinforcing layer rolled into a spiral slidable configuration and encapsulated within a polymer layer comprising a tether portion and an outer layer disposed over the inner layer. The disclosed sheath is configured to locally expand from a predetermined first diameter d1 to an expanded second diameter d2 during application of a radial outward force by passage of the medical device through the sheath.
