  • Patent number: 10117673
    Abstract: The present disclosure provides a pressure-depending clutching device for locating and safely positioning a needle in a body cavity. The device is capable of automatically engaging and disengaging the needle from a driving force. The device has a body with an interior space, a pressure-sensing element and a force-receiving element. The pressure-sensing element, the force-receiving element, and the complementary force-sending element form a driving force engaging mechanism for coupling the force-applying structure to the needle during operation. Before the needle reaches the target body cavity, the pressure in the needle causes the clutching device to assume an “engaged” state. When the needle reaches the body cavity, the change in pressure causes the clutching device to assume a “disengaged” state, thereby, automatically positioning the needle in the cavity to avoid overshooting.

  • Patent number: 10058675
    Abstract: A system for moving particles suspended in a first fluid, and for infusing them into the stream of a second fluid, includes a catheter with a multi-lumen distal separator. The separator is formed with a plurality of parallel lumens, wherein each lumen has a predetermined diameter to reduce particle flocculation. An inflatable balloon, affixed to the outside of the catheter, can be provided to regulate flow of the second fluid and thereby facilitate entry of the particles into the stream of the second fluid. A reinforcing member is employed to strengthen the catheter wall under the inflatable balloon. With this arrangement, the catheter does not kink or collapse due to the pressure exerted on the catheter wall when the balloon is inflated. In one embodiment, the reinforcing member includes an annular shaped ring. In another embodiment, the separator is positioned under the balloon and acts as the reinforcing member.

  • Patent number: 10046157
    Abstract: A connector of the present invention includes a housing and a valve, wherein the housing has a flow path and a pipe connecting port, and the valve is formed of an elastic material and is adapted to block the pipe connecting port. The valve has a substantially columnar deformable portion. The deformable portion has a top surface exposed from the pipe connecting port, a bottom surface opposite to the top surface, and a slit that extends from the top surface to the bottom surface. When the top surface is pressed by the pipe, the deformable portion of the valve will be displaced toward the flow path while elastically deforming, so that inner surfaces that define the slit will face the flow path, and the top surface will form an opening that communicates with the flow path.
