Abstract
A sheath catheter used to compress and/or retrieve a filter from a body lumen. The sheath catheter includes an elongate proximal shaft and a distal recovery sheath. The proximal shaft includes a central lumen that accommodates a shaft portion of a solid core wire to provide the catheter with better pushability. The solid core wire further includes a coiled portion that extends within the recovery sheath from a distal end of the proximal shaft. The coiled portion of the core wire provides a transition in flexibility from the stiffer proximal shaft to the more flexible recovery sheath. The recovery sheath further includes a sheath lumen that is sized to receive the filter therein.
