  • Publication number: 20250213237
    Abstract: This patent document discloses devices, systems, and associated methods for cutting, manipulating, and stabilizing tissue. A system for manipulating tissue in a prostatic urethra includes a handle body having a deployment actuator or a cutter actuator, along with an inflation port. An elongate member is coupled to a distal end of the handle body, and an expandable member is coupled to a distal end of the elongate member, which also includes a delivery body or a cutter body. The expandable member is configured to stabilize the delivery body or the cutter body against target tissue when the expandable member is expanded. A tissue manipulation structure, such as a cutter, is configured to move from a first position to a second position in which at least a portion of the structure extends into the surrounding prostatic tissue.

  • Publication number: 20240408362
    Abstract: A transdermal drug delivery device includes a reservoir, a transdermal membrane, a piston, a control rod, a spring, and a rotational cam. The reservoir is configured to hold a formulation. The transdermal membrane is configured to allow the formulation from the reservoir to pass therethrough. The piston is configured to move into the reservoir. The control rod is attached to the piston and includes a plurality of teeth thereon. The spring is configured to apply force to the control rod in the direction of the reservoir. The rotational cam has a first camming surface and a second camming surface that are configured to engage with the plurality of teeth. The rotational cam, when rotated, is configured to disengage the first camming surface from a first tooth of the plurality of teeth, thereby allowing the spring to advance the piston into the reservoir to expel the formulation onto the transdermal membrane.
