  • Patent number: 10420877
    Abstract: A system and method to irrigate a user's auditory canal. A fluid can be dispensed from a reservoir through a fluid path and out through openings of a delivery element into the auditory canal. A pump may be used to facilitate the process of dispensing the fluid. The fluid can be delivered to the user's auditory canal for a predetermined period of time. Such a time period may be user selectable. The discharge from the irrigation is removed from the user's auditory canal via a discharge port located on the delivery element. The discharge exits the delivery element and proceeds to a discharge reservoir via a discharge path. A vacuum may be used to generate a negative pressure to facilitate the removal of the discharge from the auditory canal.

  • Patent number: 9358538
    Abstract: A pipette includes a movable piston and a diaphragm that at least partly defines a fluid chamber enclosing a volume of working fluid. The piston displaces a volumetric amount of the working fluid in the chamber when moved. In response, the diaphragm displaces a smaller volumetric amount of fluid outside the chamber. A deamplification ratio is defined by the ratio of the volume displaced by the diaphragm to the volume displaced by the piston. The deamplification ratio is adjustable by adjusting or changing the diaphragm and/or by adjusting the size of the fluid chamber. The deamplifying pipette enables measuring and dispensing of very small volumes of liquid and is easily adapted to commercially available pipette components. Pipette components such as a pipette tip or adaptor may include a diaphragm to enable deamplification of the nominal volume capacity of a given pipette device.

  • Publication number: 20110270181
    Abstract: A device for delivering material to multiple surgical target locations includes a pressure reservoir selectably coupled to two or more outlets. Coupling the pressure reservoir to a given one of the outlets and pressurizing the pressure reservoir causes flowable material (e.g., bone filler material) to be dispensed from that outlet. A diverter for selectably coupling the pressure reservoir one of the outlets can be configured to trigger a pressure release valve for the pressure reservoir upon switching, thereby preventing unexpected or uncontrolled material delivery from the new outlet in response to sudden high pressure exposure.

  • Publication number: 20110230836
    Abstract: A penis erection stimulation system comprises one or more infusion needles, the tip ends of which are disposed within and implanted along with at least one first housing adjacent the patient's left and right corpora cavernosa. The respective other end or ends of the infusion needles are disposed and implanted along with at least one second housing remote from the first housing. A reservoir and a pump are also implanted inside the patient's body to supply the infusion needle with infusion liquid. A drive unit also adapted for implantation inside the patient's body is arranged for advancing and retracting the infusion needle such that its tip end penetrates the at least one first housing's outer wall at least in two different penetration areas either simultaneously or in immediate time succession, thereby injecting drugs into the patient's body for stimulating penis erection.

  • Patent number: 7988668
    Abstract: A microsyringe includes a body, a barrier movable within the body, and a flow regulator. The body includes a pressurizable chamber, an inlet fluidly connected to the pressurizable chamber, an outlet fluidly connected to the pressurizable chamber, and a cannula fluidly connected to the outlet. The flow regulator is fluidly connected to the cannula to limit the flow of a pharmaceutical through the cannula to a maximum rate. The movable barrier fluidly separates the inlet from the outlet. A pharmaceutical is disposed in a space between the movable barrier and the outlet. The inlet is designed to mechanically and fluidly couple to a hydraulic fluid delivery system. Hydraulic fluid from the inlet pressurizes the chamber, causing the barrier to move and displace the pharmaceutical out of the chamber and into the cannula. The movable barrier may be a piston or a collapsible membrane.

  • Publication number: 20110178399
    Abstract: An occlusion device for vascular surgery, suitable for clogging treatments of vascular entry sites and for endovascular interventions such as embolizations of blood vessels, treatment of arteriovenous malformations or small aneurysms, arterial dissections and the like, by releasing in an operation region a quick setting surgical glue or haemostatic fluid, through an outlet mouth of a duct. The device prevents the surgical glue from contacting within the duct a patient's biological fluids, in particular blood, which would close the duct. In the case of clogging treatments of vascular entry sites, a backflow preventing device may be provided, preferably provided by a coupling device between the duct and an introducer sheath by which an outlet mouth is kept in contact to keep in a one-way fluid tight contact against the outer surface of the introducer sheath until an injection pressure P2 is applied to cause release of the surgical glue.

    Abstract: The present invention provides devices suitable for insertion into a body passage, wherein said devices comprise a conduit and a distal head region located at the distal end of said conduit, and wherein a plurality of apertures on the surface of said head region and conduit may be used to direct a liquid spray outwards from said device. The apertures are designed and spatially arranged such that when the device is inserted into a body passage, the liquid spray emitted from said apertures is capable of both reducing the frictional contact between the device and the walls of said passage and of cleansing said passage of undesired solid and other particulate matter.

    Abstract: Disclosed is an injection system (1) for injecting liquids within a strong magnetic field, an alternating magnetic field, and/or a high-frequency electric field to be used with a technical medical system. Said injection system comprises a space (2) that is shielded from electromagnetic fields with the aid of a shield, an injection device (6) by means of which liquid to be injected can be dispensed to a patient (23), a driving mechanism for the injection device (6), by means of which at least one conveying element (11, 12) can be displaced for injection purposes, and a control and monitoring unit (8) which is located outside said space (2). The inventive injection system prevents interfering electromagnetic fields from being created exclusively by the fact that a hydraulic driving mechanism (10) is provided whose at least one hydraulic conduit (13, 14, 15, 16) is guided out of the space (2) to a pressure generating unit (71, 72, 73, 74).

  • Patent number: 7591792
    Abstract: Tissue sensors house one or more sensor elements. Each element has a housing mounted substrate and a superstrate with a planar antenna between. A transitional periphery (TP) of a superstrate outer surface interconnects a base to a plateau. At least some of the TP has a generally smooth transition. Plural elements are spaced by the housing. Alternately, the superstrate TP is flat, the housing extends to the outer superstrate surface and a shield surrounds the element. The housing is flush with or recessed below the superstrate and defines a TP between the housing and superstrate. A method converts a reference signal to complex form; plots it in a complex plane as a reference point (RP); converts a measurement signal to complex form; plots it in the complex plane as a measurement point (MP); determine a complex distance between the MP and the RP; and compares complex distance to a threshold.
