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

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.

Dispensing device and method for delivering filamentary material into a patient

Apparatus for delivering material into a patient includes a catheter having a proximal end and a distal end. Material, preferably of filamentary or thread form, is fed from a material supply into a Y-fitting having a main branch and a side branch. The side branch is connected to a source of driving fluid able to feed drive fluid under pressure into the material carrier so as to pull material forwardly and out of the distal end of the catheter. The assembly includes an inner cannula within which material is passed from the material source. This increases the speed of delivery of material though the device and reduces the amount of drive fluid which is required.

A clot retrieval system includes a delivery catheter defining a lumen and having proximal and distal ends. An elongate shaft has proximal and distal ends and is configured for receipt within the delivery catheter. An inverted sleeve has a closed end attached to a distal segment of the elongate shaft and an open end. An outer section of the inverted sleeve that includes the open end is folded over onto an inner section of the inverted sleeve that includes the closed end at a rolling fold. An expansion device is supported on the elongate shaft at an axial location proximally spaced from the closed end and aligned with or distally spaced from the open end. The expansion device is configured for radially expanding the open end of the inverted sleeve.

A thrombus retrieval device has one or more thrombus engaging elements that are movable between a retracted configuration in which they are stowed within the device and a deployed configuration in which they project from the device to snare an adjacent thrombus for removal from a blood vessel.
