  • Patent number: 11738172
    Abstract: An innovative medical device that permits rapid, minimally invasive restoration of blood flow across a vascular blockage. A method employing said device, allowing for lysis or removal of said blockage. Said device creates a temporary bypass using longitudinal structure configured for insertion into the blood vessel and adapted to deliver a side hole to a target area. The side hole defines a distal first segment and a proximal second segment with a lumen to allow blood flow therethrough to the distal end hole. In an alternate embodiment, a slidable outer sheath can cover the side hole to permit reversal of blood flow from the distal end hole to a proximal end hole located outside a patient's body by means of an aspiration controller. Alternate embodiments include an optional anchoring balloon, a macerating stent or wires, perforations for fluid delivery, and a backflow valve.

  • Patent number: 11701141
    Abstract: An introducer needle assembly including a compressible section between a rigid needle and a hub. Once a vessel is entered as determined by blood entering a syringe, the compressible section of the introducer needle is occluded by compressing the compressible section with a thumb and a finger. Neither blood nor air can pass. Since the compressible section is in a flattened area it is easier to hold the needle while the syringe is unscrewed. An operator then can begin threading a guidewire down a divide which is now easier to enter because blood is not coming out of the hub thus obscuring a lumen.

  • Patent number: 11690945
    Abstract: A dialysis valve includes a tube attached between an artery and a vein which, when elongated, simultaneously narrows in diameter at at least one location. The narrowed portion of the tube decreases the volume and velocity between the arterial and venous side of the patient to prevent damage or intimal hyperplasia on the venous side between dialysis treatments. When the valve is opened for dialysis, an unrestricted blood flow exists between the arterial and venous side, permitting a controlled, open blood flow during dialysis.

  • Patent number: 11679205
    Abstract: A digital syringe is used with conventional polymer disposable syringe construction to be practical in the medical environment. Errors associated with the larger volumes of the syringes (which exacerbate minor errors in plunger position) and the flexibility and dimensional variations of the polymer plungers are accommodated by direct measurement of the syringe plunger position rather than indirect measurement of motor position and inference of syringe plunger position. This direct measurement eliminates mechanical tolerances (“stack up”) in the motor, gear train, and lead screw on plunger movement, an effect exacerbated by flexibility of the plunger and changes in syringe resistance and medicament viscosity, for example, with different medicaments or when the syringe is refrigerated. The digital syringe may be combined with the motor unit to provide additional versatility.

  • Patent number: 11672738
    Abstract: Single dose drug dosage form dispensing devices, and methods for operating such devices are disclosed herein. In one embodiment, an apparatus includes a housing defining an actuation pathway and a pusher. At least a portion of the pusher is disposed within the actuation pathway such that distal end portions of the pusher and the housing define a volume configured to contain a drug-containing tablet. The pusher is configured to move relative to the housing in a distal direction from a first position to a second position to expel the tablet from the volume. The distal end portion of the pusher is extended from an opening in the housing when the pusher is in its second position. The housing is configured to limit movement of the pusher relative to the housing in a proximal direction towards the first position of the pusher after the tablet is expelled.

  • Patent number: 11654252
    Abstract: A securing device for an injection device which receives a syringe with a proximal end portion having a radially outwardly projecting flange, has a body with proximal and distal end portions, an opening for accepting the syringe, an outer surface, and a proximal end surface for contacting a distally-facing surface of the flange when the syringe is advanced distally, preventing further advancement. A securing arm includes a free end; a base end fixed to the outer surface; a first portion extending radially outwardly from the base end to permit the flange to pass; and a second portion extending radially inwardly in a rest position, contacting the flange as the syringe is advanced. The securing arm is elastically flexible to allow the free end to move radially outwardly, allowing the advancing flange to pass, and is biased to the rest position to secure the flange and the syringe against proximal movement.

  • Patent number: 11642466
    Abstract: Syringes are described herein. A syringe includes a syringe body, a first plunger, a biasing member, and a retention member. The syringe body defines a syringe cavity and a syringe port, wherein the syringe port is in fluid communication with the syringe cavity. The first plunger comprises a first plunger shaft extending from the first plunger, the first plunger disposed within the syringe cavity and defining a first chamber in the syringe cavity, wherein the first chamber is in fluid communication with the syringe port. The biasing member is coupled to the first plunger shaft, wherein the biasing member urges the first plunger to advance toward the syringe port. The retention mechanism prevents the biasing member from advancing the first plunger in an engaged position and permits the biasing member to advance the first plunger in a released position.
