DISPENSING DEVICE AND METHOD FOR DELIVERING FILAMENTARY MATERIAL INTO A PATENT

摘要

There are disclosed various dispensing mechanisms for dispensing filamentary material (24) through a catheter (12) into a treatment site of a patient, for example into an aneurysm sack (20) in a patient's vessel (22). In one embodiment the assembly (100) includes a conical material carrier (150) which is substantially aligned with the dispensing direction, thereby avoiding the need to have a rotating carrier. Another embodiment has a carrier (340) which is at least partially cylindrical. The carrier (150, 340) provides for efficient dispensation of filamentary material at substantial dispensing speeds.

主权项

1. Apparatus for delivering filamentary material into a patient including:
a tubular delivery element having a proximal end, a distal end and a lumen extending within the tubular delivery element from the proximal to the distal ends; a material receptacle having an aperture for receiving driving fluid into the receptacle, and an outlet coupled to the lumen of the tubular delivery element, the outlet extending in a material dispensing direction of the receptacle; a carrier element for carrying filamentary material, the carrier element having an axis substantially aligned with the material dispensing direction of the receptacle and including a body portion around which filamentary material can be wound.
