Abstract
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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
127 words
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 narrowed, tubular distal tip having a proximal end and a distal end, the tubular distal tip having a surface defining a distal opening, the diameter of the distal opening being smaller than the diameter of the proximal end of the tubular distal tip and smaller than a portion of the endoluminal therapeutic device for capturing said portion of the endoluminal therapeutic device, and the tubular distal tip being formed of a yieldable material for releasably retaining said portion of the endoluminal therapeutic device within the tubular distal tip.
Claim 2
Dependent Claim
127 words
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 narrowed, tubular distal tip having a proximal end and a distal end, the tubular distal tip having a surface defining a distal opening, the diameter of the distal opening being smaller than the diameter of the proximal end of the tubular distal tip and smaller than a portion of the endoluminal therapeutic device for capturing said portion of the endoluminal therapeutic device, and the tubular distal tip being formed of a yieldable material for releasably retaining said portion of the endoluminal therapeutic device within the tubular distal tip.
Claim 3
Dependent Claim
35 words
