Abstract

The disclosure generally relates to adjustable sheath devices for insertion into the body to provide intravascular access to various medical devices, involving a dynamically expandable sheath capable of expanding within the blood vessel when a medical device is passed through the sheath and retracting back to almost its original size when the medical device is removed from the sheath. Embodiments generally comprise a rigid collar and an elongated sleeve comprising a continuous elastomeric outer layer and an expandable inner layer.
