Abstract
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.
Claims16
A surgical access device comprising:
- an introducer having a collapsed configuration and an expanded configuration, the introducer comprising
- a circumferentially continuous layer, the circumferentially continuous layer having an overlap region with at least one fold when the introducer is in the collapsed configuration,
- a non-circumferentially continuous elastic frame, and
- a non-circumferentially continuous layer connected to the non-circumferentially continuous elastic frame and to the circumferentially continuous layer, the non-circumferentially continuous layer having a longitudinal gap when the introducer is in the expanded configuration,
- wherein the non-circumferentially continuous elastic frame is at least partially embedded within at least one of the circumferentially continuous layer and the non-circumferentially continuous layer, and
- wherein the at least one fold of the overlap region of the circumferentially continuous layer unfolds to extend across the longitudinal gap of the non-circumferentially continuous layer when the introducer is in the expanded configuration.

- a non-circumferentially continuous layer connected to the circumferentially continuous layer, the non-circumferentially continuous layer having a longitudinal gap when the introducer is in the expanded configuration, wherein the at least one fold of the overlap region of the circumferentially continuous layer flattens to extend across the longitudinal gap of the non-circumferentially continuous layer when the introducer is in the expanded configuration, and
- a non-circumferentially continuous elastic frame disposed between the circumferentially continuous layer and the non-circumferentially continuous layer, wherein the non-circumferentially continuous elastic frame is configured to maintain the introducer in the collapsed configuration,
- wherein the non-circumferentially continuous elastic frame includes a plurality of distinct projections, not joined to each other, that are axially spaced apart along a length of the introducer.
