  • Publication number: 20200261610
    Abstract: According to an aspect of the invention, an indwelling catheter is provided which comprises a catheter shaft. The catheter either comprises a light source or is adapted to receive light from a light source, and is configured such that light is transmitted from the light source into the catheter shaft. Moreover, the catheter shaft is formed of a polymeric material that transmits a quantity of light from the light source that is effective to inactivate microorganisms on a surface of the catheter shaft upon activation of the light source. For example, the light may inactivate the microorganisms directly or in conjunction with a photosensitizer. According to another aspect of the invention, a sterilization method is provided, which comprises activating the light source while the catheter is inserted in a subject.

  • Patent number: 9867908
    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.

In one aspect of the invention, a catheter is provided comprising a base polymer having a Shore A durometer of 85A or lower, with 2.0% percent by weight of surface modifier, and a radiopaque filler comprising between 20-40 percentage by weight. In another aspect of the invention, a method reducing thrombus accumulation on a venous access catheter is provided wherein the catheter surface's resistance to thrombus formation is enhanced during indwell time by lowering the durometer rating of the base polymer of the catheter without increasing the amount of surface modifier additive. In another aspect of the invention, a method of manufacturing a catheter shaft is provided, wherein the shaft is formed comprising a base polymer having a Shore A durometer of 85A or lower, with 2.0% percent by weight of surface modifier, and a radiopaque filler comprising 30% by weight barium sulfate, and optionally a colorant of 0.

  • Patent number: 9447892
    Abstract: A valve having a first housing including a first lumen extending therethrough and a first disk-facing surface, a second housing including a second lumen extending therethrough and a second disk-facing surface, where the second housing is coupled to the first housing so that the second disk-facing surface faces the first disk-facing surface. A flexible disk has at least a portion of an outer edge of the disk extending away from a plane of a central portion of the disk, the outer edge contacting the first disk-facing surface, the disk including a slit extending therethrough which, when acted upon by a fluid pressure of at least a 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, prevents fluid flow between the first and second lumens.

  • Patent number: 9440047
    Abstract: A system and method for catheter placement using ECG is provided. In certain embodiments, the system and method can generate a patient specific window for tracking a characteristic of an ECG waveform, such as the amplitude of a P-wave. The patient specific window can be utilized in a system and method for assisting in the placement of a catheter within a patient. In other embodiments, a tip location algorithm can be used with an anti-thrombogenic catheter and an intravascular electrode assembly for maintaining a high resolution intravascular signal in an ECG based catheter tip placement system.
