  • Patent number: 10709869
    Abstract: A hemodialysis split-tip catheter comprises an elongated portion, a proximal end and a distal end defining a longitudinal axis. The proximal end attaches to a hub with suture wings assembly, which in turn connected to extension tubings. The distal end has two distal tip segments splitted from each other. The first distal tip segment has a concave shape with respect to the longitudinal axis and the second distal tip segment has an approximately J-shape with respect to first distal tip segment. Diameter of concave shape of first distal tip segment is larger than diameter of J-shape of second distal tip segment to facilitate backward bend of second distal tip segment with respect to first distal tip segment after a catheter insertion inside a blood vessel to face a blood flow direction.

  • Patent number: 10688297
    Abstract: A system and method for deterring potential illicit use of extended-installations of catheters associated with patient care. A pair of legs are moveably associated together to collectively define a needle-defeating pathway between a pair of scissoring, offset, pinching surfaces disposed on mating surfaces of the legs when the legs are closed and clamped to an indwelling catheter. A single-use tamper evident locking system both maintains the legs closed and provides tamper evidence when opened, such as by disabling the locking system from further locking operation.

  • Patent number: 10046174
    Abstract: In one example, a system electrically stimulates target cells of a living animal using an elongated structure, a modulation circuit and a light pathway such as provided by an optical fiber arrangement. The elongated structure is for insertion into a narrow passageway in the animal such that an end of the elongated structure is sufficiently near the target cells to deliver stimulation thereto. The modulation circuit is for modulating the target cells while the elongated structure is in the narrow passageway, where the modulation circuit is adapted to deliver viral vectors through the elongated structure for expressing light responsive proteins in the target cells. The light pathway is used for stimulating the target cells by delivering light to the light-responsive proteins in the target cells.

  • Patent number: 9039657
    Abstract: Implantable devices and methods for delivering drugs and other substances to locations within the body of a human or animal subject to treat or diagnose sinusitis and a variety of other disorders. The invention includes implantable substance delivery devices that comprise reservoirs and barriers that control the rate at which substances pass out of the reservoirs. The delivery devices may be advanced into the body using guidewires, catheters, ports, introducers and other access apparatus. In some embodiments the delivery devices may be loaded with one or more desired substance before their introduction into the body. In other embodiments the delivery devices are loaded and/or reloaded with a desired substance after the delivery device has been introduced into the body.

  • Publication number: 20150141959
    Abstract: Methods and kits for delivering pharmaceutical agents to the adventitia and other regions outside the external elastic lamina (EEL) surrounding a blood vessel utilize a catheter having a needle. The needle is positioned in up to 5 mm beyond the EEL and delivers an amount of pharmaceutical agent sufficient to circumferentially permeate around the blood vessel and, in many cases, extend longitudinally and radially along the blood vessel. Confirmation that a delivery aperture of the needle lies beyond the EEL may be required before delivering the pharmaceutical agent. In one example, the catheters are used to deliver dexamethasone and other anti-inflammatory agents to the peripheral and other vasculature to treat peripheral vascular disease and other conditions.

  • Patent number: 9033954
    Abstract: A catheter for insertion into a vascular system of a patient and for directing fluid flow includes a catheter body having a longitudinal axis and longitudinally spaced proximal and distal catheter ends with an intermediate catheter portion defined therebetween. An intermediate catheter outlet in the catheter body is located in the intermediate catheter portion and is spaced longitudinally from the proximal and distal catheter ends. A first lumen is defined within the catheter body and has longitudinally spaced proximal and distal first lumen ends with a reversing bend located therebetween, the first lumen providing fluid communication between the proximal catheter end and the intermediate catheter outlet. The reversing bend is located longitudinally between the intermediate catheter outlet and the distal catheter end. The reversing bend directs fluid flow to turn approximately 180° as the fluid flows through the first lumen. A method of using the catheter is also described.

  • Publication number: 20150119853
    Abstract: A method of controlling and changing the shape of a catheter in situ that includes the use of two nested catheters. The catheters have two different shapes that may add, cancel, or override each other when one catheter is placed within the other. The shape may be changed by advancing or rotating one catheter relative to the other catheter.

  • Publication number: 20150119854
    Abstract: Tear-away sheath introducers for catheters and methods for making and using such introducers are described. The sheath introducers contain movable valves that are encapsulated in a movable housing that allows the valve to move along the introducer axis. As the movable valve and housing travel along the axis, a portion of the hub protrudes past the valve and is exposed. As well, the sheath introducers can also contain a stationary valve and housing that can be opened to expose a portion of the hub when a conduit penetrates the stationary valve. The conduit can include a one-way, two-way, or other suitable valve actuator that can penetrate and open the valve, yet remain attached to a portion of the introducer when the introducer is split for removal from a patient. In both instances, the protruding portion of the hub contains a friction-free pathway for a catheter into the sheath introducer.

    Abstract: In one instance, a catheter for replacing or adding a guide wire into a patient is provided. The catheter includes a first rapid exchange lumen, a second rapid exchange lumen, and a releasable wire-securing device. A second guide wire is placed in the second rapid exchange lumen and secured into position. The catheter is then advanced along the first guide wire until in position, and then the second guide wire is released from the wire-securing device and advanced into the desired position. The catheter is then removed. Other catheters and methods are also disclosed.

First and second tubular components of the apparatus each include a distal portion that is at an acute angle with respect to a longitudinal axis of the apparatus. The second tubular component is rotatably disposed within the first tubular component. In the curved configuration, the distal portions of the first and second tubular components are positioned to extend at substantially the same acute angle with respect to the longitudinal axis of the apparatus. In the substantially straightened configuration, the distal portions of the first and second tubular components are positioned such that the curvatures thereof counterbalance each other. The first and second tubular components may be used in an occlusion bypassing apparatus for re-entering the true lumen of a vessel after subintimally bypassing an occlusion.
