Publication number: 20210196310Abstract: A wound debridement system includes a wound dressing having an active layer and a wound interface layer. The active layer is formed from one or more drive elements arranged about a film layer, by which the drive elements are attached to the wound interface layer. Activation of the drive elements is configured to cause the movement of the wound interface layer relative to a tissue site to which the wound dressing is applied. The drive elements may include one or more drive members formed of a material having a shape memory effect configured to transition the drive members between expanded and collapsed configurations and/or one or more motors configured to translate or oscillate the active layer. The wound interface layer may be formed having an abrasive wound-facing surface, such that the movement of the wound interface layer causes a mechanical disruption and debridement of debris at the tissue site.Type: ApplicationFiled: May 23, 2019Publication date: July 1, 2021Inventors: Brett L.

Publication number: 20210196317Abstract: In some embodiments an apparatus for providing access for a medical procedure in a patient's body cavity includes a stem configured for insertion through an opening in a body cavity wall. The stem has a bore and a cap is disposed at a proximal end thereof and includes an entry port in communication with the bore which receives an instrument to be inserted into the body cavity. An inflatable annular seal is disposed on the stem proximate the cap and a conduit extends through the cap providing pressurized gas at a first outlet in fluid communication with the body cavity providing insufflation pressure. A second outlet of the conduit is in fluid communication the seal, which when disposed inside the body cavity proximate the wall and inflated by pressurized gas, bears on an inner surface of the wall urging the cap into contact with an outer surface of the wall while sealing the opening.Type: ApplicationFiled: January 6, 2021Publication date: July 1, 2021Inventors: Evan Rittenhouse Jones, Maxime Blain, Christopher Dean Smith

Publication number: 20210196318Abstract: This document discusses, among other things, systems and methods for robotically assisted implantation of an implant in a patient. A system includes an implant-positioning unit configured to engage an elongate member of the implant, and a control console communicatively coupled to the external positioning unit. The control console can have a user interface that enables a user to input motion control instructions. The control console can generate a motion control signal, according to a specific motion control instruction, to control the external positioning unit to propel the implant into a target implant site. The system can be used to robotically control the delivery and positing of a cochlear implant during a hearing-preservation cochlear implant surgery.Type: ApplicationFiled: February 19, 2021Publication date: July 1, 2021Inventors: Christopher Kaufmann, Parker Reineke

Publication number: 20210196320Abstract: In some embodiments, a method includes a shaft having a side catheter guide attached thereto via a guide coupler into an inferior vena cava and a superior vena cava such that the guide coupler is disposed in a right atrium, and applying a distal force to a proximal portion of the side catheter guide such that a distal end of the side catheter guide deflects laterally about the guide coupler towards a septum. The method further includes extending a side catheter that is disposed within the side catheter guide distally from the side catheter guide towards and into contact with the septum. The method further includes, with the side catheter in contact with the septum, extending a septum penetrator that is slidably disposed within the side catheter distally from the side catheter such that the septum penetrator pierces the septum.Type: ApplicationFiled: March 4, 2021Publication date: July 1, 2021Applicants: University of Maryland, Baltimore, University of Maryland Medical System LLC, Protaryx Medical Inc.Inventors: James S.
