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 dispensing assembly (30) includes a chamber having a spherical carrier (50) onto which filamentary material (24) is wound. Upon injecting driving fluid into the dispensing assembly (30) filamentary material (24) unwinds from the spherical carrier (50) and is pulled through the catheter (12) to be dispensed from the distal end (18) of the catheter.

摘要： A clot retrieval device, for example to be used in a thrombectomy, is provided including a catheter, an elongated member, and a knitted basket with a proximal end coupled to the catheter and a distal end coupled to the elongated member. The elongated member is movable between an expanded position and a compressed position relative to the catheter and is configured so that the knitted basket expands radially and compresses as the elongated member is moved to the compressed position. The knitted basket is comprised of a plurality of wires coupled together by a plurality of windings. Each winding comprises one of the plurality of the wires twisted about another of the plurality of wires.

摘要： 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.

摘要： A neuro-surgery assembly includes a neuro-catheter slidably received over a wire guide. The wire guide includes an inner tube positioned within an elongate hollow tube that includes a pattern of openings at its distal segment to provide an atraumatic tip for reaching sensitive locations in a brain. The wire guide is changeable between a stiff condition in which the inner tube is pressurized and a soft condition in which the inner tube is depressurized. The user may switch between the stiff and soft conditions to negotiate the tortuous pathway to a brain treatment site without a need to swap out to a different wire guide to support advancement of the neuro-catheter.

摘要： An improved catheter and method of using the same is described. The catheter has at least one anchoring element at its distal tip region which is used to secure the catheter to a pre-implanted medical device, such as a stent, during the filling of an aneurysm. Such action prevents a buildup of pressure or of material from forcing the distal tip of the catheter to be forced from the aneurysm before the procedure is complete.

摘要： A medical device for collecting objects from a body lumen comprises a catheter, a basket having a closed first end and an open second end, and an actuator connected to the closed first end of the basket, the catheter and basket moveable relative to one another between a first configuration and a second configuration to draw objects from a body lumen into the basket. In the first configuration the closed first end of the basket is inside the catheter and the open second end is everted over at least a part of the closed first end. The apparatus may be actuated to pull the closed first end of the basket further into the catheter and invert the second end of the basket, the second end scraping the sides of the lumen as it inverts, surrounding an object in the lumen, and drawing the object into the basket.

摘要： A stent assembly (10) is formed with a plurality of stent rings (12) which have sections (16, 18, 24) which are of a non-biodegradable material and struts and tie bars (20, 14) which are at least partially biodegradable. The stent ring (12) thus partially biodegrades in a patient over time. The structure is such that the apices (16, 18, 24) of the stent ring (12) are of a non-biodegradable material and thus able to behave as a conventional non-biodegradable stent, that is with the same flexibility and expansion force consistent with such stent rings. Parts (34, 44) of the stent ring (12) will degrade in time, thereby reducing the restoring force produced by the stent ring (12) and reducing the amount of foreign material retained within a patient's body. In one embodiment, the stent ring (12) will separate into individual components after a period.

摘要： A medical filler delivery assembly includes a micro catheter for delivering filler material such as filamentary material into an aneurysm in a vessel, the assembly also including a positioning mechanism which includes a support element made of knitted wires, as well as an expansion mechanism for expanding the support element within the vessel. The wires form an array of polygonal, preferably rhomboidal cells, the wires being intertwined at their junctions by at least one turn around one another, the intertwined regions extending in the longitudinal direction of the support element. The support element is able to trap the micro catheter in position and in practice such that its distal end is disposed within the aneurysm sac.

摘要： A guide wire includes a plurality of segments which can interlock rotatably relative to one another. A locking element extends through a lumen of the segments. When the locking element is in an unlocked condition the segments are able to rotate relative to one another. In this mode, the guide wire is very flexible. The locking element can be tightened to cause the segments to lock in engagement with one another and to fix the guide wire in position. In practice, the guide wire can be fixed in a curved or bent configuration, which enables the guide wire to provide a rigid support for a microcatheter or other element of an introducer assembly. The guide wire therefore can exhibit both extreme flexibility and stiffness.
