  • Patent number: 10596338
    Abstract: Tracheal tube systems may include first and second tubes and an inflatable balloon. The first tube may be flexible and hollow and have first and second open ends. The inflatable balloon may be affixed to and circumferentially surround a portion of the first tube. The inflatable balloon may include an indentation sized and positioned to accommodate a portion of a second tube positioned therein, when the inflatable balloon is inflated. The second tube may be hollow and have a multiplicity of holes along a sidewall not in contact with the balloon. The second tube may be configured to be coupled to a suction device that creates a negative pressure in the second tube. When the tracheal tube system is inserted in a patient's trachea, the negative pressure in the second tube may act to remove, or suction out, fluids and other matter from the trachea.

  • Patent number: 10321941
    Abstract: An intramedullary bone fixation device is disclosed herein. The device includes a first longitudinally extending member, a second longitudinally extending member, and a coupling member. The first longitudinally extending member includes a connector end and a bone engagement end opposite the connector end. The second longitudinally extending member includes a connector end and a bone engagement end opposite the connector end. The coupling member is configured to engage the connector ends of the respective longitudinally extending members, thereby coupling the first longitudinally extending member to the second longitudinally extending member. The device may be provided in an kit form at least partially unassembled. The device may be delivered into a fracture and fully assembled within the fracture or adjacent bone via percutaneous or minimally invasive surgical procedures. The device, on account of its configuration and assembly, may be considered modular in some cases.

  • Publication number: 20180236146
    Abstract: Devices for treating fistulas may include a cap with a vacuum port, a spacer with a lumen therethrough, a first distal anchor, and a second distal anchor. The devices may be configured to transmit negative pressure through the vacuum port, the spacer lumen, and an opening in the first distal anchor to releasably seal the first and second distal anchors to tissue, thereby securing the devices in place. The first distal anchor may also include a plurality of openings that form vacuum pathways that transmit the negative pressure. The cap may also include a flush lumen, which may allow flushing of a fistula tract without removal of the device. Methods of treating fistulas may include applying negative pressure to a fistula treatment device to anchor the device and flushing a tract of the fistula using a flushing fluid with the fistula treatment device in-situ.

  • Patent number: 9750509
    Abstract: A tissue removal kit or assembly comprises a cannula and a tissue removal probe axially slidable within the cannula. The tissue removal probe comprises an elongated member a distal end configured to curve when distally deployed from the cannula. The tissue removal probe further comprises a drive shaft rotatably disposed within the member, and a rotatable tissue removal element (e.g., an abrasive burr) disposed on the drive shaft adjacent the member distal end. The curved member distal end may associate the tissue removal element, which has its own axis of rotation, with a radius of revolution about the longitudinal axis of the member. The member is laterally flexible and resilient, so that the radius of revolution can be adjusted. In this manner, the tissue removal element can remove tissue around an adjustable arc.

  • Publication number: 20170035444
    Abstract: Tissue removal probes comprise an elongated member, a drive shaft rotatably disposed within the member, and a rotatably tissue removal element mounted to the distal end of the drive shaft. One tissue removal element comprises a plurality of tissue-cutting filaments affixed at proximal and distal ends of the tissue removal element. The cutting filaments may have optional hinge points that allow the distal end of the tissue removal element to be inverted, thereby transforming the tissue removal element from a tissue-cutting device to a tissue-grasping device. Another tissue removal element may have a blunted tip to prevent distal tissue trauma and an irrigation port to provide irrigation fluid to the removed tissue and/or tissue removal element. Another tissue removal element has a proximal and distal spiral grooves that are oppositely pitched, so that removed tissue can be collected in the middle of the tissue removal element.
