There are disclosed various dispensing mechanisms for dispensing filamentary material through a catheter into a treatment site of a patient, for example into an aneurysm sack in a patient's vessel. In one embodiment, the dispensing assembly includes a chamber having a spherical carrier onto which filamentary material is wound. Upon injecting driving fluid into the dispensing assembly filamentary material unwinds from the spherical carrier and is pulled through the catheter to be dispensed from the distal end of the catheter. The apparatus includes a pressure sensitive valve disposed at the inlet or the outlet of the receptacle, the pressure sensitive valve being closed when the pressure of driving fluid is below a threshold and open when the pressure of driving fluid is above the threshold. The pressure sensitive valve, when open, allows fluid flow through the chamber and dispensation of filamentary material from the outlet.

Apparatus for delivering filamentary material into a patient

Rotatable control handles and methods of using rotatable control handles are described herein. An example embodiment of a rotatable control handle comprises a handle, a compressible member disposed within the handle, a cap attached to the handle, and a cannula rotatably attached between the handle and the cap. The handle comprises a first member and a second member that is releasably attachable to the first member.

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