Embodiment Construction

[0029] The figures show a generally hollow or tubular structure according to the invention. As used herein, the terms "tubular" and "tube" are to be interpreted broadly and are not limited to structures that are right cylinders or strictly circumferential in cross-section or have a uniform cross-section throughout their length. For example, tubular structures or systems are generally illustrated as substantially right-cylindrical structures. However, the tubular system may have a tapered or curved outer surface without departing from the scope of the present invention.

[0030] Such as Figure 1A , Figure 1B and figure 2 The illustrated example of a separation system 10 of the present invention may have a proximally elongated delivery hypotube assembly 100 and a distal delivery tube 300. Implantable medical device 12 is engaged at one end of distal delivery tube 300. The implantable medical device 12 may be an embolic coil, although it should be appreciated that virtuall...

Abstract

The invention discloses an implantable medical device detachment system with a split tube. The detachment system for delivering an implantable medical device to a target location of a body vessel hasa generally hollow distal tube. The distal tube includes a proximal end, a distal end, and a compressible portion of the tube itself, between the proximal and distal ends which is axially movable froma compressed to an elongated condition. A generally hollow proximal tube has a proximal end and a distal end. An engagement system engages and deploys the implantable medical device engaged at the distal end of the distal tube. The engagement system moves the compressible portion to the compressed condition when engaging the implantable medical device, and deploys the implantable medical device and releases the compressible portion to the elongated condition.

Description

technical field [0001] The present invention generally relates to an interventional medical device system that can navigate through the vessels of the body of a human subject. More particularly, the present invention relates to a detachment system for deploying an implantable medical device to a target location in a body vessel and a method of using the same. Background technique [0002] The use of catheter delivery systems for positioning and deploying therapeutic devices such as dilatation balloons, stents, and embolization coils in the body's vasculature has become a standard procedure for treating endovascular disease. Such devices have been found to be particularly useful in treating areas where conventional procedures are impossible or pose significant risk to the patient (for example, in treating aneurysms in intracranial vessels). Performing surgical procedures to treat defects in intracranial vessels is very difficult and often risky due to the delicate tissue sur...
