    摘要: A vascular prosthesis delivery system comprises a radially self expandable vascular prosthesis and a delivery sheath with a lumen with a smaller diameter storage region and a larger diameter delivery region. A prosthesis is housed within the storage region and is movable into the delivery region for delivery at a target site within a patient. The delivery force required to move the prosthesis from the delivery region into the patient can be less than the force required to move the prosthesis from the storage region into the delivery region. In some examples, the storage region defines a tapered lumen expanding in diameter in a distal direction. In some examples, the storage and delivery regions are generally coextensive and define a tapered lumen expanding in diameter in a distal direction. A method stores a vascular prosthesis in the storage region and delivers it to a target site from the delivery region.

    摘要: A catheter assembly includes a catheter, including an inner member and a sheath, extending from a handle. The handle includes a housing, a braking assembly, a carriage and a carriage driver. The braking assembly comprises a braking element within the housing interior and a braking element rotator. The carriage comprises at least one carriage braking surface engaging the braking element. The carriage driver, such as a spring, biases the carriage towards the proximal end of the handle. The inner member has a proximal end secured to the housing. The sheath has a proximal end secured to the carriage. Rotating the braking element causes the carriage to move proximally as the carriage braking surface slides along the braking element. This causes the sheath to move proximally relative to the inner member.
