Zusammenfassung:	Disclosed herein are hemostasis seals with low pass-through friction force. The disclosed seals are configured for use with transcatheter delivery systems or vascular access sheath systems. The seals are a unitary design that provide low pass-through friction when passing a catheter through the seal. The specifics of the design that provides the desirable low pass-through friction include the physical configuration of the seals and the material used for the seals. The disclosed seals include an outer portion, an inner annular portion, and a webbing portion connecting the outer portion to the inner annular portion, forming a suspended O-ring. The suspended O-ring provides an opening through which a delivery device can be passed and applies a relatively low friction force on the delivery device as it is passed through the opening.
