摘要： A tumescent fluid infusion apparatus for use in treatment of a vascular disease includes a needle attached to a valve device. The valve device is designed to receive tumescent fluid from a fluid source. When the valve device is in an open position, it administers the tumescent fluid from the fluid source through the needle channel to allow a single hand of a user to control the needle insertion and the infusion of the tumescent fluid to free the other hand for operating a probe such as an ultrasound probe to eliminate the requirement of a second operator. The infusion apparatus also allows a user to control the amount of infused fluid without requiring syringe changes.

摘要： An endovascular sheath device for use with a thermal treatment apparatus is provided. The device includes a longitudinal tube which is designed to receive a thermal treatment device and is designed to be inserted into a blood vessel. An ultrasonically visible reinforcement element is disposed along the length of the longitudinal tube. The reinforcement element such as a braided wire provides several functions including increased visibility under ultrasound, clearer identification of sheath tip, and increased durability to protect the fiber from needle punctures during tumescent injections into the perivenous space. The wire reinforcement also increases shaft torquability and kink resistance during sheath insertion and withdrawal.

摘要： A multiple tube catheter, such as a hemo-dialysis catheter, has first and second tubes which are attached to each other over a zone by one or more longitudinally extending wires which joins the two tubes over that zone. When a catheter is implanted in the patient, the attached zone is within the patient so that the catheter cannot be removed or advanced. When the catheter is to be removed, the longitudinally extending wire or wires are pulled proximally out of the tubes involved so that the two tubes can be separated and individually removed. A flexible separating prong within the patient and proximal of the zone holds the tubes apart to further assure that the catheter cannot be moved.

摘要： The method of treating varicose veins and other vascular diseases provides sclerosant fluid through a catheter into the body vessel to be treated. The catheter has a lumen and a plurality of sidewall exits. The sclerosant fluid is provided under sufficient pressure so that it comes out of each exit as a jet of fluid with sufficient velocity to impinge on the vessel wall substantially orthogonal to the wall and thus minimize dilution of the sclerosant fluid and optimize coverage. A movable sheath on the catheter permits selecting a portion of the exits to be uncovered and thus create an infusion zone for the jets of sclerosant fluid which approximately match a desired treatment zone.

摘要： A permanent blood clot filter which may be retrieved is provided. The blood clot filter includes a filter section and an alignment section. The filter section includes a filter hub and a set of filter legs whose downstream ends are connected to the filter hub. The filter legs extend axially and radially outwardly from the filter hub to form a conical configuration. The alignment section includes an alignment hub and a set of alignment ribs whose downstream ends are connected to the alignment hub and whose upstream ends are connected to the filter legs. The alignment ribs extend from the alignment hub radially outwardly and then further extend radially inwardly to provide centering of the filter.

摘要： An endovascular laser treatment device preferably includes a catheter having a hub at its proximal end, an optical fiber for insertion into the catheter, a fiber connector attached to the optical fiber at a selected distance from the distal end of the optical fiber, and a temporary stop removably mounted around the optical fiber. The treatment device has two positions: a protective position and an operating position. As the fiber is inserted through the catheter, the temporary stop rests against the hub and places the fiber tip in the protective position where the distal end of the optical fiber is positioned near the distal end of the catheter, but is still disposed inside the catheter. When the temporary stop is removed and the fiber connector is coupled with the catheter hub, the fiber tip is in the operating position where the distal end of the optical fiber extends past the distal end of the catheter by a predetermined distance to expose the fiber tip.

摘要： A removable or absorbable vena cava filter is introducible through a relatively small bore catheter. These filters formed of a single high-memory wire. The wire has a coiled cylindrical portion and a coiled conical portion. The wire assumes a straight configuration when in a catheter. The coils of the cylindrical portion have a sufficiently large diameter contact the walls of the inferior vena cava with sufficient force to hold the coils in place against the inferior vena cava. The cylindrical portions of the wire has an anchor attached to it in a non-absorbable embodiment of the invention. The conical portion of the wire has a segment which aids in the removing of the filter from the vena cava.

摘要： A vascular access catheter is disclosed that has a catheter shaft with a distal end portion with a distal tip having a sloped face that is positioned at an acute angle from the distal tip relative to a longitudinal axis of the catheter shaft. A first, second, and third lumen extend longitudinally through the catheter shaft. The third lumen is configured for receiving a guidewire and may extend a partial length of the catheter or substantially the entire length of the catheter. The first lumen has an aperture located in the angled edge distal end portion of the catheter next to the distal tip and communicates with the first lumen. The second lumen has an aperture that is positioned in the outer surface of the catheter shaft that is in communication with the second lumen, and is spaced proximally from the first lumen aperture. The catheter includes a fluoropolymer additive with specific compositions and/or purity levels.
