An elastic percutaneous elastic introducer sheath is disclosed which can locally expand and reduce to accommodate a transcatheter medical device. The elastic introducer sheath includes a non-circumferentially continuous elastic frame, a liner, and a jacket.
Claims20
An elastic surgical access device comprising:
- a circumferentially continuous biocompatible material layer;
- an elastic frame;
- and
- a non-circumferentially continuous biocompatible material layer connected to the elastic frame and to the circumferentially continuous biocompatible material layer, the non-circumferentially continuous biocompatible material layer having a longitudinal gap in an expanded configuration.
