  • Wound closure device with protective layer and method of use
    Patent number: 11590030
    Abstract: A negative pressure wound closure system and methods for using such a system are described. Preferred embodiments of the invention facilitate closure of the wound by utilizing a stabilizing structure that preferentially contracts to provide for movement of the tissue. Some embodiments may utilize a protective layer, such as a mesh or net layer, attached to a top surface of the stabilizing structure. The protective layer prevents a drape positioned over the stabilizing structure from being drawn into cells of the stabilizing structure, and permits visualization of the collapse of the cells.

  • Tympanostomy tube and placement device
    Patent number: 11547609
    Abstract: A tympanostomy tube placement device has a needle with a tip, and a retainer at the needle tip. The retainer is within and retains by pulling radially inwardly a tympanostomy tube distal flange in a folded configuration extending distally. Movement of the needle tip in the proximal direction causes the adhesive bond to break and the distal flange releases to an unconstrained deployed position. Due to the axial folding of the distal flange its radial dimension does not affect deployment through the membrane.

  • Oxygen therapy with fluid removal
    Patent number: 11547789
    Abstract: An apparatus for treating a tissue site includes a dressing, an oxygen source, a valve, and a negative-pressure source. The dressing is configured to be sealed around the tissue site. The oxygen source is fluidly coupled to the dressing and configured to provide a low flow of oxygen. A first port of the valve is fluidly coupled to the dressing and the valve moves between a closed position preventing flow through the valve and an open position permitting flow through the valve. The negative-pressure source is fluidly coupled to a second port of the valve and provides negative pressure to the second port of the valve at a non-therapeutic level. The valve separates the negative-pressure source from the dressing and selectively opens when a positive pressure is applied on an upstream side of the valve.

  • Uterine hemorrhage controlling system and method
    Patent number: 11517336
    Abstract: An insertable device is designed to control uterine hemorrhaging after birth by facilitating contractile movement of the uterus. An insertable device comprises a tube having a connecting portion and a suction portion and a seal positioned along the length of the connecting portion proximal to the suction portion. Upon insertion of the suction portion and seal into the uterus, the seal abuts a vaginal canal and forms a seal between a vaginal opening and the uterus. The suction portion comprises a first loop having an opening that is oriented away from an interior wall of the uterus when inserted into the uterus. The connecting portion of the tube couples to a pump that when actuated generates a negative pressure within the uterus, resulting in a uniform mechanical stimulus to the uterine wall in order to facilitate tamponade and contractile movement of the tissue.

  • Urodynamic investigation apparatus, system, and methods
    Patent number: 11511074
    Abstract: A urodynamic investigation apparatus for receipt of urine from a bladder is provided. The apparatus is characterized by a tubular element, first and second fittings, and a sleeve element, for select passage of urine there through, within the tubular element. The tubular element is characterized by opposing first and second end portions, and a port. The fittings are adapted to be received by the opposing end portions of the tubular element so as to delimit an apparatus chamber. The sleeve element, suspended between the fittings within the chamber, has collapsed and open configurations. The collapsed configuration is indicative of a no urine flow condition, and the open configuration indicative of a urine flow condition, with the sleeve element urine flow condition being a function of pressure applied to the chamber via the port of the tubular element.
