  • Patent number: 8260439
    Abstract: A selective nerve stimulation patch includes a substrate having a top surface and a bottom surface, integrated components overlying the top surface of the substrate and being electrically interconnected with one another for generating at least one nerve stimulating signal, electrodes integrated into the substrate and exposed at the bottom surface thereof for applying the at least one nerve stimulating signal to a target nerve, a waterproof, breathable cover overlying the substrate and the integrated components, and a support flange surrounding the substrate and coupling the cover and the substrate together. The support flange has a top surface that slopes downwardly toward an outer perimeter thereof, and at least a portion of the cover conforms to the sloping top surface of the support flange. In one embodiment, the patch generates a high frequency waveform with properties such as amplitude, frequency and the like chosen so as to overcome tissue impedance and the stimulation threshold of the target nerve.

  • Patent number: 8252599
    Abstract: Sample processing units useful for mixing and purifying materials, such as fluidic materials are provided. A sample processing unit typically includes a container configured to contain a sample comprising magnetically responsive particles, and one or more magnets that are in substantially fixed positions relative to the container. A sample processing unit also generally includes a conveyance mechanism configured to convey the container to and from a position that is within magnetic communication with the magnet, e.g., such that magnetically responsive particles with captured analytes can be retained within the container when other materials are added to and/or removed from the container. Further, a sample processing unit also typically includes a rotational mechanism that is configured to rotate the container, e.g., to effect mixing of sample materials disposed within the container. Related carrier mechanisms, sample processing stations, systems, and methods are also provided.

  • Patent number: 8152762
    Abstract: A retractable safety syringe may comprise a needle, needle holder, syringe body, and a plunger. A proximal portion of the body and a piston of the plunger may define a variable vacuum compartment. A through hole pneumatically connecting ambient air and the variable vacuum compartment may be formed through a thumb platform and rigid shaft of the plunger for allowing air to escape out of the variable vacuum compartment when a piston of the plunger is traversed toward the retracted position and allow air to be introduced into the variable vacuum compartment when the piston is traversed toward the engaged position. A retraction force may be created by the variable vacuum compartment by covering an entrance of the through hole and traversing the piston to the engaged position. At the engaged position, the piston may engage the needle holder and the retraction force may retract the piston, needle holder and needle into the syringe body to prevent accidental needle pricking and needle reuse.

  • Patent number: 8128576
    Abstract: An implantable urodynamic system includes an implantable first device deployable in a patient's bladder, an implantable second device deployable in a patient's vaginal canal, and a data acquisition and analysis module or processing unit external to the body of the patient. The first device includes a magnet and an inductive coil, and the second device includes a magnet, an inductive coil and a battery. When deployed in the patient's body, attraction between the magnets maintains the two devices in close proximity to one another to effect an inductive coupling between the coils so that the first device may be powered by the battery of the second device. The urodynamic system is intended to facilitate measurement, collection, and wireless transmission of real-time, or near real-time, data (bladder pressure, abdominal pressure, and temperature) from an ambulatory patient.

  • Publication number: 20120022447
    Abstract: A retractable safety syringe may have a needle, needle holder, syringe body, and a plunger assembly. A proximal portion of the body and a piston of the plunger may define a vacuum chamber. The plunger assembly may comprise a distal piston and a proximal piston, with an intermediate chamber disposed between the two plungers. A vent through the syringe body pneumatically connects ambient air and the intermediate chamber allowing air to escape out of the intermediate chamber when a plunger assembly traversed toward the engaged position and allow air to be introduced into the intermediate chamber. A retraction force may be created by the vacuum chamber by traversing the plunger assembly to the engaged position. At the engaged position, the distal piston may engage the needle holder and the retraction force may retract the needle holder and needle into the syringe body to prevent accidental needle pricking and needle reuse.

  • Publication number: 20120022498
    Abstract: A retractable safety syringe may have a needle, needle holder, syringe body, a shaft seal, and a plunger assembly. A proximal portion of the body and a piston of the plunger may define a vacuum chamber. The plunger assembly may comprise a shaft coupled to a piston. The shaft may have at least one non-engaging portion and at least one engaging portion. The plunger assembly is movable between a storage position and working positions. In the storage position, little or no force is exerted on the shaft seal by the non-engaging portion. In the working positions, the engaging portion is in sealing engagement with the shaft seal to seal the vacuum chamber. Stopper movement of the retractable safety syringe may be reduced or eliminated if the retractable safety syringe is prefilled.

  • Publication number: 20120012116
    Abstract: The embodiments of the present tracheostomy valves include a flexible diaphragm abutting a rib shaped substantially as a flat plate. Opposite the rib, the diaphragm abuts a boss and forms an uninterrupted seal therewith. As the tracheostomized patient inhales, the diaphragm bends about the rib, interrupting the seal and allowing air to flow smoothly into the valve. The features of the various embodiments contribute to a positive seal at all times except during inhalation, and low resistance to airflow through the valve during inhalation.

  • Patent number: 8088104
    Abstract: A retractable needle safety syringe is provided having a braking mechanism. The braking mechanism may be disposed at a proximal portion of a syringe body of the syringe. The braking mechanism may comprise a brake member which is traversable between a braking position and a released position. At the braking position, the brake member frictionally engages an outer surface of the shaft of a plunger of the syringe. The frictional engagement counterbalances a retraction force that urges a piston of the syringe toward a retracted position. When the brake member is traversed to the released position, the brake member does not press against the outer surface of the shaft. As such, the retraction force may traverse the piston toward the retracted position and traverse a needle and needle holder into the body of the syringe.

  • Patent number: 7972300
    Abstract: A retractable needle safety syringe is provided having a braking mechanism. The braking mechanism may be disposed at a proximal portion of a syringe body of the syringe. The braking mechanism may comprise a brake member which is traversable between a braking position and a released position. At the braking position, fingers of the brake member frictionally engage an outer surface of the shaft of a plunger of the syringe. The frictional engagement counterbalances a retraction force that urges a piston of the syringe toward a retracted position. When the brake members are traversed to the released position, the fingers do not press against the outer surface of the shaft. As such, the retraction force may traverse the piston toward the retracted position and traverse a needle and needle holder into the body of the syringe.

  • Publication number: 20110118627
    Abstract: Disclosed is a disposable patient interface for an intraductal fluid aspiration system. The interface has a flexible tubular distal member for contacting the patient, and a proximal support portion forming a vacuum chamber therein. The support portion has a vacuum aperture for communication with a source of vacuum, and a retention structure for releasably mounting within a hand piece of an intraductal fluid aspiration system. The flexible member preferably has a low modulus of elasticity and a high tear strength, such that it can be stretched to fit over a rigid support without rupture.
