  • Patent number: 9033925
    Abstract: An improved pump, reservoir and reservoir piston are provided for controlled delivery of fluids. A motor is operably coupled to a drive member, such as a drive screw, which is adapted to advance a plunger slide in response to operation of the motor. The plunger slide is removably coupled to the piston. A method, system, and an article of manufacture for automatically detecting an occlusion in a medication infusion pump is provided.

  • Patent number: 8968248
    Abstract: A feeding tube and method for introducing a feeding tube within the gastrointestinal tract of a patient, whereby the feeding tube is introduced by using a variation of the Ponsky “pull” method of feeding tube placement. The feeding tube comprises an elongate shaft having a distal end and proximal end. The feeding tube also comprises a coupling structure for coupling the feeding tube to a pull wire, the coupling structure be proximal of the distal end of the feeding tube shaft. The feeding tube further comprises a guiding structure for aligning the pull wire with the distal end of the shaft. The feeding tube is introduced within the patient by attaching the previously placed pull wire to the coupling and guiding structures of the feeding tube, and then pulling the pull wire so as to pull the feeding tube into and through the gastrointestinal tract of the patient.

  • Patent number: 8951227
    Abstract: A device is for the administration of injectable products with controlled flow rate, with a container (23) in the form of both a syringe and an ampoule preloaded with the injectable product, an injection port (25) and a control valve (21) for controlling the outlet rate and pressure arranged between the injectable products and the injection port (25). A device for reducing the outlet flow rate depends on the pressure increase applied during the administration of the injectable product, the administration being moderated by closing the valve (21) when the pressure exceeds a predetermined limit. A device prevents the backflow of fluids during the administration of the injectable product. The valve (21) can be positioned both in the container (23) and at an injection end (27) including the injection port (25) which is coupled to the container (23).

  • Patent number: 8882705
    Abstract: An improved steerable catheter with in-plane deflection comprises a catheter body having proximal and distal ends and a lumen extending therethrough and a tip section at the distal end of the catheter body. The tip section comprises a flexible plastic tubing having a pair of diametrically-opposed lumens extending therethrough. The catheter also provides two puller wires manipulated through a control handle at the proximal end of the catheter body. Each puller wire extends through one of the pair of lumens in the tip section and through the lumen of the catheter body and is anchored to the control handle at its proximal end and anchored to the tip section at its distal end. The deflection mechanism is configured to generally define a plane along which deflection most readily occurs and an edge along which deflection is most readily avoided.

  • Patent number: 8733736
    Abstract: An apparatus for delivery of fluids to a patient includes an inlet tube and an outlet tube connected to each other at an angular joint. A rotary valve and a piston are fitted to the angular joint forming a chamber. The rotary valve is provided with a priming channel notch and a pumping notch. For priming operation with the fluid delivery apparatus, a user sets the rotary valve to a priming position. During pumping operation, the rotary valve rotates in coordination with the piston to transfer a quantum of fluid from the inlet tube to the outlet tube via the chamber. A second piston is optionally provided on the outlet tube for smoothing out flow rate pulsations.

  • Patent number: 8715238
    Abstract: A pumping device is disclosed, as for use with an enteral feeding assembly. In one form the pumping device is a diaphragm pump including a first dome portion, a second dome portion, and a flexible membrane located between the first and second dome portions. A pressure differential is created between the two chambers thus created by membrane, so as to meter fluid (to be delivered) to a patient. The fluid to be delivered may be located in one of the chambers. A portable fluid pump is also provided including a syringe and spring pump drive mechanism mounted in a casing. The spring pump drive mechanism has two piston devices in fluid communication with each other. As one piston device moves in one direction within its associated driving barrel, it serves to drive the other piston device.
