Abstract: 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.

Abstract: It is an object and advantage of this invention to provide an improved device and method that uses targeted laser wavelength to treat a diseased vessel. An advantage of this invention is targeted ablation of diseased vessels without harming non-target tissue. This new technique allows for a controlled ablation, may not require injection of tumescent anesthesia prior to treatment and may decrease unwanted or unintended side effects.

Abstract: A valve comprises a first housing including a first lumen extending therethrough and defining a first disk-facing surface and a second housing including a second lumen extending therethrough and defining a second disk-facing surface, the second housing being mated to the first housing so that the second disk-facing surface faces the first disk-facing surface in combination with a flexible disk gripped between gripping portions of the first and second disk-facing surfaces, the disk including a slit extending therethrough which, when acted upon by a fluid pressure of at least a predetermined threshold level opens to permit fluid flow between the first and second lumens and which, when acted upon by a fluid pressure less than the threshold level remains sealed preventing fluid flow between the first and second lumens and a relief well between opposing portions of the first and second housings radially outside the gripping portions, a width of the relief well exceeding a width of a radially outer portion of the flexible disk so that the radially outer portion of the disk is free to move therewithin.
