  • Patent number: 11541203
    Abstract: A urinary catheter may include a catheter shaft and a connector coupled with the proximal end of the catheter shaft. The connector may have a first arm ending in a fluid outlet configured to allow urine to flow out of the urinary catheter and a second arm with an aperture and ending in an inflation inlet used for introducing inflation fluid into the urinary catheter. The catheter may further include a primary lumen, an inflation lumen, a retention balloon mounted to the catheter shaft proximal to a fluid inlet and over a distal filling hole, and a pilot balloon mounted on the second arm of the connector over the aperture. The pilot balloon inflates at an inflation pressure that is higher than the inflation pressure of the retention balloon and lower than a predetermined pressure threshold.

  • Patent number: 11541205
    Abstract: A coated urinary catheter or urinary stent device includes a urinary catheter or stent which, in a deployed position, includes or defines a protective surface area and a protected surface area and a coating upon at least a portion of the protective surface area. The coating includes a lubricant and an antimicrobial and/or pH buffering material. The device is configured such that, upon application of negative pressure to the catheter or stent, tissue of a urinary tract of a patient conforms or collapses onto the protective surface area and is thereby prevented or inhibited from occluding one or more protected drainage holes, ports or perforations of the catheter or stent.

  • 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.

  • 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.

  • Patent number: 11504457
    Abstract: A wound irrigation system and method of making and using. The system uses a pored, closed-ended delivery conduit to enhance the consistency and speed with which anti-microbial or related irrigation fluids may be delivered in order to promote cleansing, debridement and biofilm reduction in wounds. The ease of use of the system as a moist wound healing cascade makes it applicable to both in-home and in-facility environments that is not offered through traditional instillation negative pressure systems. In one form, the fluid delivery conduit is used as part of a dual-conduit approach in order to also help promote the removal of drainage, waste, irrigation overflow or other fluid from the wound. Utilization of such a pored, closed-ended delivery conduit in conjunction with a separate drainage conduit infusing helps reduce the frequency of dressing changes as well as the likelihood of microorganism formation and colonization.

  • Patent number: 11484688
    Abstract: Minimally invasive catheter relates to the field of eversible catheters. It is primarily intended for use as a urinary catheter, but is also usable in other fields. As a urinary catheter this minimally invasive catheter 1 used as an indwelling or intermittent catheter with transurethral or suprapubic approach. This catheter has specific technical solution for eversible motion where tubular membrane 2, attached between distal part 36a of the handle 36 and distal part 3a of the inner tube 3, can in one case free slide between these two parts and in another be fixed to form hermetically sealed space 14. Free sliding of membrane ensures eversible principle of motion during placement and withdrawal of the catheter 1. Fixation of membrane allows a formation of hermetically sealed space 14 with fluid to make catheter surface smoother and softer, and a balloon 33 to hold catheter 1 in place for prolonged period of time.

  • Patent number: 11464947
    Abstract: An aortic perfusion catheter is an apparatus that is used during surgery for acute ascending aortic dissection to reduce postoperative injuries from profound hypothermia, ischemia, and reperfusion. The apparatus may include at least one main cannula, an inflation cannula, a drainage cannula, and a balloon tamponade. The at least one main cannula helps maintain blood perfusion to the body during the procedure to reduce postoperative injuries. The inflation cannula enables the selective inflation and deflation of the balloon tamponade to facilitate the insertion and removal of the balloon tamponade along with the at least one main cannula within the descending thoracic aorta. The balloon tamponade prevents blood flow into the operative area to maintain the operative area clear during the procedure. The drainage cannula enables the drainage of blood that may escape the balloon tamponade as well as other bodily fluids.

  • Patent number: 11464940
    Abstract: System and method for bi-directional fluid injection includes a retrograde introducer, a retrograde cannula having an inlet opening, intermediate opening and outlet opening, an antegrade introducer and an antegrade cannula. The retrograde introducer is configured to engage with the retrograde cannula and to insert the retrograde cannula into a fluid channel. The antegrade introducer is configured to engage with the antegrade cannula and to insert the antegrade cannula into the fluid channel from within the retrograde cannula through the intermediate opening. After insertion of both cannulas, both introducers are removed. In operation, fluid flows into the retrograde cannula inlet and a portion thereof is diverted to the antegrade cannula which flows the portion in a first direction in the channel, the remainder of the fluid flows out the retrograde cannula outlet in an opposite direction in the channel. The system is removed from the channel using the introducers in reverse order.
