Abstract
The endoluminal device delivery assembly and method for release and deployment of an endoluminal therapeutic device at a desired location for treatment within the vasculature of a patient utilizes an elongated flexible tubular catheter with a tubular distal tip formed of a yieldable material mounted to the distal end of the catheter for releasably holding the proximal end of the endoluminal device. The endoluminal device can be dislodged from the tubular distal tip by a pusher member or pressurized fluid to expel the endoluminal device through at the desired location for treatment within the vasculature of a patient. A flexible coil can be mounted to the distal end of the elongated pusher member to provide for improved tracking.
Claims3
An endoluminal delivery device for deployment of an endoluminal therapeutic device at a desired location for treatment within the vasculature of a patient, the endoluminal therapeutic device, the endoluminal device delivery comprising:
- an elongated flexible tubular catheter having a distal end;
- and
- a tubular distal tip having a proximal end mounted to the distal end of said catheter, an inner lumen, and a distal end with a surface defining a distal opening for releasably holding the proximal end of the endoluminal device within the inner lumen of said tubular distal tip, wherein the diameter of the distal end of the tubular distal tip is smaller than the diameter of the proximal end of the tubular distal tip, said tubular distal tip being formed of a yieldable material for releasably retaining an endoluminal therapeutic device.
