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 includes 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 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. The knitted wire configuration of the support element provides sufficient holding force to the distal end of the micro catheter and also has an open structure which permits continuation of fluid flow through the vessel. The entire assembly can be removed from the vessel after the delivery of filamentary material, thereby not retaining within the vessel any foreign object such as a stent.

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： An introducer assembly includes a catheter having a proximal end, a distal end extending to a distal tip of the introducer assembly, and an outer catheter wall. The catheter includes a medical device holding portion proximate the distal end, a guide wire lumen extending between the proximal and distal ends, and a side opening extending through the outer wall to the guide wire lumen. The side opening and the guide wire lumen are simultaneously open and the guide wire lumen and side opening are able to receive a guide wire therethrough. The catheter is flexible at least in the location of the side opening. The catheter also includes a plurality of one stiffening mandrel lumens extending from the proximal end and a plurality of stiffening mandrels.

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： An introducer assembly (10) includes a catheter (12) having a proximal end (14), a distal end (16) extending to a distal tip of the introducer assembly, and an outer catheter wall. The catheter (12) includes a medical device holding portion (34) proximate the distal end, a guide wire lumen (100) extending between the proximal and distal ends, and a side opening (50) extending through the outer wall to the guide wire lumen. The side opening (50) and the guide wire lumen (100) are simultaneously open and the guide wire lumen and side opening are able to receive a guide wire therethrough. The catheter (12) is flexible at least in the location of the side opening, such that a guide wire (28) fed from the distal end (16) can pass through to the proximal end (14) when the catheter is substantially straight and can pass from the distal end through the side opening (50) when the catheter is curved at the location of the side opening. The catheter (12) also includes a plurality of one stiffening mandrel lumens (104, 106) extending from the proximal end (14) and a plurality of stiffening mandrels sized to fit within the stiffening mandrel lumens and in some forms able to slide therewithin and in other forms enclosed within the stiffening mandrel lumens. The mandrels have different lengths disposed along the length of the catheter and can be of substantially uniform diameter.

摘要： A wire guide for feeding a medical catheter through the body passage of a patient to a distant target site within the body has a variably flexible distal portion. The distal portion facilitates threading the guidewire in a tortuous path through acute bends at branch junctions in the body passages of the patient. The wire guide end is able to feed into very delicate vessels such as ventricles of the brain and the spinal canal without puncturing the wall or damaging organs.

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 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.

摘要： A guide wire assembly for medical use includes at least a portion which is formed of a plurality of inter-cooperating elements forming a flexible section of the guide wire assembly, and specifically a section that can have varying flexibility. A control device passes through a lumen extending for the whole length of the guide wire and is typically fixed at a distal end of the assembly. The control device is used to change the flexibility of the guidewire assembly and in some embodiments to lock it in position. The elements have tapering internal lumens for accommodating the control device, particularly when the guide wire is bent.

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.

摘要： A magnetic guidance system (20) for guiding a guidewire (70) or other elongate medical device includes a magnet unit (20) disposed in one implementation adjacent a head end of a patient table (30). The magnet unit is disposed on a magnet support which enables the magnet unit (20) to move in a periodic motion substantially around a single plane. The preferred motion is a rotary motion about a patient's head, which creates a repetitive repulsive force at the distal end of the medical device, causing the distal end of the medical device to move in different directions within the patient's vasculature, useful in assisting the guidance of the medical device through tortuous vessel structures. The repetitive alternating medical field makes guidance of a medical device within a patient's vasculature a relatively simple task.
