  • Patent number: 11969591
    Abstract: An Example tool for implanting a pacemaker lead includes a body that includes a recess, a first electrical contact positioned within the recess, and a projection coupled to the body. In addition, the tool includes a second electrical contact positioned on the projection. The recess is configured to receive the pacemaker lead therein such that a first electrode of the pacemaker lead is to engage with the first electrical contact and a second electrode of the pacemaker lead is to engage with the second electrical contact. A rotation of the tool about a central axis of the pacemaker lead is configured to rotate the first electrical contact and the first electrode together about the central axis and to slidingly engage the second electrical contact along the second electrode.

  • Patent number: 11751759
    Abstract: One aspect of the invention provides a trocar including: a central cylinder defining a central channel and having a distal end adapted and configured for insertion within a subject; one or more gas outlets located within the central cylinder proximate to the distal end of the trocar; and one or more liquid outlets located within the central cylinder on a proximal side of the one or more gas outlets. The one or more liquid outlets are adapted and configured to dispense a liquid when an endoscope is withdrawn from a fully extended position within the central channel of the trocar to a position proximate to the one or more liquid outlets. Distal advancement of the endoscope to a position adjacent to the one or more gas outlets removes liquid from a distal end of the endoscope.

  • Publication number: 20220339436
    Abstract: A method of improving electrical conduction across an impaired region of a tissue (e.g., myocardial tissue), includes applying an electrically conductive wiring carbon nanotube fibers) across the impaired region. The electrically conductive wiring can become associated with non-impaired regions of the tissue on opposite sides of the impaired region by suturing. The method can also be utilized to treat or prevent cardiac arrhythmia in a subject (e.g., ventricular arrhythmia). The electrically conductive wiring includes carbon nanotubes, such as carbon nanotube fibers, Such electrically conductive wiring can be used to transmit electrical signals to a tissue or sense electrical signals from the tissue. Suture threads including carbon nanotubes, such as carbon nanotube fibers, are provided.

  • Patent number: 10799333
    Abstract: A magnet assisted surgical device, system, and method employs magnetic sections, catheters, and guidewires to modify tubular stentgrafts in-situ. One example application provides a more reliable way for surgeons to modify stentgrafts insitu to allow blood flow to continue to branching blood vessels that would otherwise be blocked by the stentgraft itself. One such method includes placing a tip section of the device in the desired location, deploying a stentgraft, placing a magnetic device inside the stentgraft, connecting the magnetic device to the tip section, and excising the portion of the stentgraft held between the magnet and the tip section.
