摘要： A system and method for vessel catheterization is provided, having an introducer sheath and a catheter. The introducer sheath can include a handle and a sheath body extending from the handle. An access lumen is provided in the introducer sheath, and can include a tapered portion that is sized to receive a tapered outer surface of the catheter. The catheter may be a central venous catheter, such as a peripherally inserted central catheter, including a hub, a catheter body with at least one lumen extending distally from the hub, and at least one tube extending proximally from the hub. The introducer sheath is preferably a splittable sheath. The catheter can be inserted into the access lumen, and translated until confronting surfaces of the tapered outer surface of the catheter body and the tapered portion of the introducer sheath contact one another. This arrangement can inhibit buckling and/or kinking of the catheter during insertion, and improve initial catheter tip positioning.

摘要： A method for occluding a body vessel in a patient to block or reduce blood flow therethrough includes puncturing a blood vessel wall at a proximal vessel entry site with a hollow needle and extending the needle through the proximal entry site into the vessel lumen. The needle is extended through the vessel lumen and extended through the vessel wall at a distal vessel exit site into the extravascular space surrounding the distal vessel exit site. An expandable biocompatible material, such as expandable extracellular matrix (ECM) material, is then ejected though the distal end of the needle into the extravascular space. Then, while continuing to eject the expandable biocompatible plug material, the distal end of the needle is retracted back through the distal vessel exit site into the vessel lumen, such that the plug material continuously extends between the extravascular space surrounding the distal vessel exit site into the vessel lumen. When the plug material is delivered into the lumen of the vessel, the plug material expands, anchoring the plug material to the vessel wall, whereby the plug material forms an occluding plug in the vessel lumen blocking or reducing blood flow therethrough.

摘要： An elongate element, in particular a catheter, has a curved shape imparted to its end by a device comprising razor blades which are mounted on a pivotal linkage mechanism. Upon pressing actuator members against the restoring force of spring elements, the razor blades are constrained by the pivotal linkage mechanism to follow a desired curved path.

摘要： A hemodialysis catheter with a plurality of umbrella-like wire members covered with a film which works as a thrombus blocker and can easily and effectively remove the thrombus is disclosed. The hemodialysis catheter has a proximal lumen, the arterial lumen, and a distal lumen, the venous lumen. An elongate member is longitudinally put in either the proximal lumen or the distal lumen, or two elongate members in both lumens. A plurality of umbrella-like wire members are connected to the end of the elongate member. When the hemodialysis catheter is put in the vessel but not in use, the end of the lumen is capped off by the plurality of umbrella-like wire members covered with a film. When it is ready to use, the doctor can pull the elongate member which connects to the plurality of umbrella-like wire members out off the lumen inverting the plurality of umbrella-like wire members and clearing away any thrombus that has formed.

摘要： A vascular occlusion device for occluding a body cavity. The device includes an elongate member having an inflation lumen, an occlusion lumen, and a first portion extending distally from a proximal end and a second portion extending distally from the first portion to the distal end. An inflatable proximal balloon is disposed about the first portion and an inflatable distal balloon is disposed about the second portion. The inflation lumen is configured to inflate at least one of the balloons. The occlusion lumen is configured to introduce an occlusive material into the body cavity by way of an occlusion port located between the two balloons to occlude the body cavity. In some examples, the body cavity includes a patent foramen ovale.
