  • Patent number: 10751086
    Abstract: A cannula assembly for use in laproscopic surgery includes a cannula having a proximal end for use in orientating the assembly into an abdominal cavity, a distal end for insertion into a patient, and a passage through which surgical instruments can be inserted. An expandable feature in the form of an anchor is located toward the distal end of the cannula and is selectively expandable and collapsible. The feature in its expanded state prevents withdrawal of the cannula. A collar is pushed distally until it releasably cinches to the outside of the abdominal cavity thereby creating an airtight seal and stabilizing the assembly. The collar has a friction fit with the cannula designed to prevent excessive force against the cavity walls.

  • Patent number: 10751206
    Abstract: A method for delivering catheters, and stents composed of soft, compliant polymers through anatomical passages. These devices have a bulbous or enlarged anchorage end with a diameter greater than the rest of the catheter. To facilitate implant and delivery a pusher catheter or sheath with an internal lumen larger than the outer diameter of the catheter but smaller than the outer diameter of the bulbous or enlarged anchorage end is provided. The distal end of pusher catheter or the sheath physically engages the proximal end of the bulbous or enlarged anchorage end and applies an axial force to coaxially advance the catheter over a guidewire through anatomical passages. This method allows a physician to move the catheter to an anatomical site without the device exhibiting buckling due to axial force applied. Similarly, this delivery method will allow more force to be applied to the distal end of the catheter diminishing the likelihood of buckling.

  • Patent number: 10702367
    Abstract: A percutaneous transluminal angioplasty device having an embolic filter mounted to the catheter shaft at a location distal to the angioplasty balloon and downstream from the blockage to capture embolic particles that may be set loose into the blood stream as the angioplasty procedure is performed. The embolic filter is normally collapsed against the catheter shaft to facilitate introduction and withdrawal of the device to and from the operative site. Once the angioplasty balloon is properly positioned, however, means operatively associated with the embolic filter are actuated to erect the filter to operatively position a filter mesh across the lumen of the vessel.

  • Patent number: 10687846
    Abstract: Surgical devices having a plurality of outwardly-biased flexible fins capable of inward movement such that the fins converge to provide both a passageway for surgical instruments to traverse towards a surgical site, and provide a substantially impermeable seal, thus providing for fluid retention during the surgical procedure. The outwardly-biased flexible fins provide for soft tissue compression, decreasing the length of the lumen or passageway through which instruments pass, allowing for a wider range of movement of instruments and better access to the surgical site, especially in patients with greater amounts of fat tissue that would otherwise require longer lumen lengths in prior art endoscopic cannulas.

  • Patent number: 10687977
    Abstract: A device for modeling a pessary is disclosed. A matrix of individually expandable balloons are mounted around a shaft, which holds fill lines for each balloon. The balloons are expandable with fluid to a desired volume and/or pressure, according to comfort and fit determined by real-time patient feedback. Because the volumes and the positions of the balloons are known, a calculation of the dimensions of the vaginal canal can be made, so that the matrix of expandable balloons models the vaginal canal.
