  • Patent number: 11690702
    Abstract: A user-controllable urinary catheter prosthesis (20) is provided for minimally-invasive insertion into a subject. The prosthesis (20) includes a proximal intra-urethral assembly (22), configured to be inserted entirely within a urethra (102) via a meatus (104). A user-activatable hydraulic activator (50) is disposed along a flexible intra-urethral catheter (30, 430), which is shaped so as to define a urinary outlet (40, 440) at a proximal end (41, 441) thereof. A distal bladder assembly (32, 132, 232, 332) is configured to be disposed in a bladder of the subject, and includes a bladder anchor (48). A hydraulic valve (60, 160, 260, 360) is configured to assume an open state, in which urine flow is allowed between the distal bladder assembly (32, 132, 232, 332) and the urinary outlet (40, 440); and a closed resting state, in which urine is entirely blocked from entering the distal bladder assembly (32, 132, 232, 332) and exiting the urinary outlet (40, 440).

  • Patent number: 9056173
    Abstract: The present invention provides a dry-powder inhaler device comprising: a casing; an air inlet located at a first terminus of the casing; a powder delivery port located at a second terminus of the casing, which is positioned distal to the air inlet; and an elongated assembly located within an interior of the casing. A first terminus is located proximally to the air inlet, a second terminus is located proximally to the powder delivery port, and the assembly is fitted within the casing such that said assembly partially rotates therein about a single axis. The assembly has at least one compartment containing dry-powder, which is located proximally to the second terminus. The compartment with a dry-powder comprises a porous structure encasing the dry-powder; whereby airflow through the device causes the assembly to partially rotate within the casing about a single axis and release the dry-powder in the airflow.

  • Publication number: 20130276914
    Abstract: The proposed valves and/or fluid pumps are controlled with a piezoelectric actuator, which provides very low power consumption, low cost, very compact designs, high speed response, long life, hysteresis free and linear operation, long displacement over 50 mm and high torque over 400 Newton. A steady continuous flow of a media is achieved by supplying a power profile to the actuator via an electronic circuitry connected to electrodes attached to the piezoelectric actuator.

  • Publication number: 20100139655
    Abstract: A dry-powder, breath-powered inhaler device comprising at least one air inlet, a flow chamber and an air outlet leading to a mouthpiece, the flow chamber further comprising at least one drug-containing volume and at least one scraping means and a rotor assembly comprising an axis and at least one blade; wherein the inhalation action of the patient applied at the air outlet causes air to enter the at least one air inlet such that the air interacts with the at least one rotor blade causing the rotor to rotate and thus generate breath-driven, relative motion between the at least one drug-containing volume and the at least one scraping means, such that fine particles of powder are released from the drug-containing volume; the arrangement being such that the air exits the flow chamber via the periphery of the flow chamber, carrying out the fine particles to the outlet to be inhaled by the patient.
