  • Patent number: 10349927
    Abstract: A soft material retractor includes at least two soft actuators, each actuator having at least one pressurizable interior space, wherein the actuator has a first flexible resting state and a second stiffer pressurized state; and a flexible sheet spanning the actuators such that the actuators can be spaced apart from each other by a distance selected to displace a volume of material of a body cavity. The retractor can be uses for holding open wounds or incisions, with trochars, or to displace anatomical features such as organs within a body cavity.

  • Publication number: 20190022875
    Abstract: A method of making an actuator having a complex internal shape includes providing a core of a shape that defines an internal cavity of an actuator; molding an actuator around the core, wherein the core occupies the internal cavity of the actuator, the cavity having an opening; generating a pressure differential between an exterior surface of the actuator and the internal cavity of the actuator, wherein the external pressure is less than the internal pressure, to expand the actuator cavity; and removing the core through the opening of the expanded actuator cavity.

  • Publication number: 20180104059
    Abstract: Therapy is provided to living tissue by contacting the living tissue with at least one reservoir loaded with cells or a therapeutic composition, wherein the reservoir is in fluid communication with at least one conduit that includes a refilling port. A constituent selected from (a) cells, (b) bioagents from the cells or (c) the therapeutic composition is released from the reservoir to the living tissue. The reservoir is then refilled with (i) cells, (ii) nutrients for cells, or (iii) additional therapeutic composition; and (a) cells, (b) bioagents from the cells or (c) the therapeutic composition continue to be released from the reservoir to the living tissue after the refilling.

  • Patent number: 9561544
    Abstract: The present invention is directed to a bi-stable coupling for controlling the depth of a tool insertion, such as drilling, and similar processes. The bi-stable coupling can be used to penetrate (e.g., drill or push) through a material layer of unknown thickness without plunging the tool into the adjacent layer. In accordance with the invention, in a first state, force is applied to the tool to initiate penetration and a reactive force maintains the device in the first state during penetration and when tool penetrates the material, the reactive force is diminished enabling the device to transition to a second state in which the tool becomes retracted. In medical applications, the invention allows for drilling through bone of unknown thickness without plunging into the adjacent soft tissue.
