  • Patent number: 11400259
    Abstract: An apparatus includes a catheter, an introducer, and an actuator. A distal end portion of the introducer is configured to be coupled to a peripheral intravenous line. The introducer defines an inner volume having a first portion that defines an axis parallel to and offset from an axis defined by a second portion. A first portion of the actuator is movably disposed in the first portion of the inner volume. A second portion of the actuator is movably disposed in the second portion of the inner volume and coupled to the catheter movably disposed in the second portion of the inner volume. The actuator moves the catheter between a first position, in which the catheter is disposed within the introducer, and a second position, in which at least a portion of the catheter is disposed within the peripheral intravenous line.

  • Patent number: 11389243
    Abstract: A light measurement device measures the intensity of laser light output from a catheter tip end portion of a catheter having a built-in optical fiber. The light measurement device includes a light receiving part which receives the laser light output from the catheter tip end portion and a mounting part which is disposed at a position facing the light receiving part. The mounting part defines a position of a tubular hoop, which accommodates the catheter, with respect to the light receiving part. In a state in which the position of the hoop is defined by the mounting part, the light measurement device obtains the intensity of the laser light by inputting the laser light to the light receiving part.

  • Patent number: 11197980
    Abstract: A catheter insertion system includes a housing extending along a longitudinal axis. A needle extends distally from a distal end of the housing. The needle has a longitudinal passage coaxially aligned with the housing. A catheter has a length and is sized and shaped to be advanced from a retracted position within the longitudinal passage of the needle to an extended position with at least a portion of the catheter length extending beyond a distal tip of the needle. The needle is typically configured to be retracted back into the housing after the catheter has been advanced, thus providing an integrated catheter and catheter insertion apparatus. After needle retraction, the housing may be taped to the patient's skin while the needle remains protected within the housing. A luer on the catheter may then be connected to a fluid or other source in an otherwise conventional manner.

    Abstract: A deep vein intravenous introducer has a wheel located toward the front end of the device that can be rotated by the index finger of the user. After placement of the needle in the lumen of the vessel, the user rotates the wheel, which advances the wire guide through the center of the needle and into the patient. Once the guide wire is advanced into the vessel lumen the catheter can be advanced over the guide wire with a hub or finger tab on the catheter close to the index finger. The operation can be performed by one hand without moving the hand from its initial position. The user can then simultaneously use the other hand to operate an ultrasound detection device during insertion without the assistance of another person.

    Abstract: A device for insertion of a flexible needle or other such instrument into a tissue, incorporating a collapsible support guide which supports that part of the needle which has not yet penetrated the tissue, preventing it from buckling, and an arrangement which pulls the needle from its proximal end to provide sufficient force for the penetration process. The collapsible support guide can be a pair of flexible strips connected along their length and enclosing the needle along its uninserted length in order to support it, with a mechanism at the distal end of the device to peel the strips from the needle as it is inserted. Insertion can be achieved by a pair of rollers engaging and advancing the strips distally. Alternatively, a telescopic support tube can be used to support the needle, the tube collapsing telescopically as the needle is inserted, to maintain clearance above the needle.

  • Publication number: 20130310750
    Abstract: A medical device including a portion similar to a Veress needle, useful for relief of tension pneumothorax. The device includes a hollow tubular stylet disposed movably within a hollow needle or cutting cannula, and an optionally releasable locking mechanism for keeping the stylet in place protruding distally beyond the sharpened distal end of the cutting cannula to prevent puncture of internal organs after the chest wall has been intentionally punctured. The stylet can also be moved outward from within the cannula to push a plug of tissue from the bore of the cannula. A valve or a connector for a tube may be provided at a proximal end of the stylet.

  • Patent number: 8545447
    Abstract: Material transport catheters and methods for their use rely on rotation of an impeller within a catheter body and a clearing element for preventing buildup of materials at the opening of the catheter body. The impeller preferably comprises an inner tube or shaft having a helical rotor fainted over an outer surface thereof. The clearing element may comprise a free end of a structure near the distal end of the catheter body for disrupting clot, wherein the free end of the structure extends into the distal opening of the catheter body to break up materials as the impeller is rotated. Alternatively, the clearing element may comprise a cutting member disposed at the distal opening of the catheter body.

  • Patent number: 8231601
    Abstract: A long catheter can be inserted into a patient while eliminating the need for a sterile field by incorporating the long catheter into an infusion tubing and carrying it in with the infusion. The long catheter has a structure that prevents it from leaving the infusion tubing when fully extended and therefore becomes a connector for fluids to transfer down the long catheter by infusion through the infusion tubing. Use of an adjustable seat connector allows the long catheter to be stopped at varying points during insertion and even to allow the long catheter to be reversed by pulling suction on the infusion tubing and retracting the long catheter back into the infusion tubing. The long catheter also remains within the sterile confines of the infusion tubing and therefore is prevented from becoming contaminated.

  • Patent number: 8226600
    Abstract: The intervertebral disc is avascular. With aging, endplates become occluded by calcified layers, and diffusion of nutrients and oxygen into the disc diminishes. The disc degenerates, and pain ensues. Conduits are delivered and deployed into the intervertebral disc to reestablish the exchange of nutrients and waste between the disc and bodily circulation to stop or reverse disc degeneration and relieve pain. The intervertebral disc installed with semi-permeable conduits may be used as an immuno-isolated capsule to encapsulate donor cells capable of biosynthesizing therapeutic molecules. The semi-permeable conduits establish the exchange of nutrients and therapeutic molecules between disc and bodily circulation to treat a disease without using immunosuppressive drugs.
