Document Type and Number:
Japanese Patent JP5846505
Kind Code:
B2
Abstract:
A delivery system having an improved handle allowing operation of the delivery system with one hand while maintaining accuracy in delivery and deployment of a prosthesis in a body lumen. The delivery system includes a sheath and a handle. The handle includes a slide shaft having a threaded outer surface, and a hub assembly coupled to the sheath. The hub assembly includes an inner slider having a thread tooth pivot support, a thread tooth pivotably mounted to the thread tooth pivot support, a distal sleeve having a thread tooth press member pressing on the thread tooth, and a proximal sleeve. Motion of the distal sleeve relative to the inner slider pivots the thread tooth on the thread tooth pivot support to engage and disengage the hub assembly with the threaded outer surface. The distal sleeve is rotatably coupled to the proximal sleeve, and the proximal sleeve is prevented from rotating to provide a stable grip to allow operation of the catheter with one hand.
