Patent number: 11690702Abstract: 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).Type: GrantFiled: January 26, 2021Date of Patent: July 4, 2023Assignee: RAMBAM MEDTECH LTD.Inventors: Amnon Kritzman Kadron, Ilan Gruenwald, Yehuda Yarmut, Arie Oscar Holtz, Nir Sinai

Patent number: 9056173Abstract: 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.Type: GrantFiled: January 30, 2011Date of Patent: June 16, 2015Assignee: AESPIRA LTD.Inventors: Dan Adler, Amnon Kritzman, Arie Holtz
