  • Patent number: 10065030
    Abstract: A device for reducing agent penetration at an insertion site is provided that has a porous inner sleeve fluidly connected to a conduit. A vacuum or hydrodynamic source is fluidly connected to the conduit. The device is stabilized by fibroblast in-growth and inhibits bacterial colonization. A device is also provided that has a conduit having a bore and an outer conduit surface. The outer conduit surface is optionally nanotextured to promote fibroblast adhesion and limit bacterial residency. A sleeve is provided in fluid communication with the bore of the conduit, and is formed from materials characterized by a pore matrix through which vacuum or hydrodynamic draw is achieved in a process to promote stabilization and reducing bacterial colonization by draw fluid from an area around the surrounding the site of the device. The sleeve optionally has a distal nanotextured surface.

  • 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.
