Abstract
A retractable catheter including an elongate tubular sheath having at least in a distal portion made of a relatively flexible material, a reinforcing structure made of a relatively inextensible material incorporated in the relatively flexible material of the sheath along at least a portion thereof, and a pull element for transmitting a pull force longitudinally to the sheath and the reinforcing structure, wherein the pull element is connected directly to a portion of the reinforcing structure exposed from the relatively flexible material to transmit the pull force directly to the reinforcing structure.
Claims16
A retractable catheter, comprising:
- an elongate tubular sheath having at least in a distal portion made of a relatively flexible material;
- a reinforcing structure made of a relatively inextensible material incorporated in the relatively flexible material of the sheath along at least a portion thereof;
