Abstract

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.

Description

Background technique [0001] The present invention relates to a handle for implant adjustment and to an associated adjustment assembly. Delivery devices have long been used in a variety of medical procedures, including maintenance of channels, vascular cavities or lumens, organ cavities or lumens, conduit cavities or lumens, such as vascular occlusions, for the delivery of medical care and other interventions. Today, there are many endovascular prostheses on the market for use in the treatment of aneurysms, stenosis and other vascular diseases. Stents, stent-grafts, and other vascular prostheses are known for use in the treatment of a myriad of vascular diseases. With percutaneous intervention, a number of vascular prostheses are inserted into the body through a catheter and deployed at the desired treatment site. The present invention relates to a controllably adjustable artificial blood vessel, such as a stent, a stent graft, a filter or an occlusion device, etc. for the tr...
