  • Patent number: 11911059
    Abstract: The present disclosure provides a surgical shunt assembly tool that provides a more efficacious grip on the catheter tubes and prevent the tip of the catheter from buckling while the catheter is pushed onto the tip of the valve during installation of shunts during CSF shunt surgery. The tool includes standard handles such as used in a shodded mosquito tool having a clamping jaw integrated into the distal end section of the handle. The distal jaw includes two forcep jaw sections each having a proximal end integrally formed with a distal end of a distal end arm section of one of the two handle arms, and a distal end section extending away from the distal end arm section. The distal end sections of the forcep jaw sections are cylindrically shaped such that when the forcep jaw is closed by bringing the two forcep jaw sections together, a cylinder is formed having a diameter substantially equal to a diameter of a catheter tube to be attached to a shunt valve tip.

  • Publication number: 20240057858
    Abstract: A deployable and flexible tooltip camera is provided for integration within a shaft of an endoscopic tool. The tooltip camera includes a camera mounted to a distal tip of a curved tube which is capable of rotational and translational movement to provide a wide field of view of a tooltip of the endoscopic tool during an endoscopic procedure. The tube retains its curved shape when in use to provide a unique perspective view of the tooltip, but can then be withdrawn into a shaft of the endoscopic tool such that the entire tooltip camera and tube are retained within the shaft of the endoscopic tool and can pass through a cannula. The curved tube may be formed of a super-elastic memory alloy like Nitinol and pre-shaped into an s-curve using a two-step heat treatment process to attain the necessary curvature, and further laser-patterned with holes to attain the necessary flexibility.

  • Patent number: 11730505
    Abstract: A flexible elongate shaft assembly which includes an elongate flexible tube having at least one joint built into the elongate flexible tube, and the at least one joint comprised of at least one notch. Each notch includes a contact-aided compliant notch topology built into the elongate flexible shaft configured to cause each notch to mechanically interfere with itself and self-reinforce during bending of each notch resulting in an increase in stiffness of each notch to prevent buckling and plastic deformation of the elongate flexible shaft assembly, and assume a predetermined and designed bending shape of the elongate flexible shaft assembly. The flexible elongate shaft assembly is incorporated into a flexible articulate surgical tool that provides the needed stiffness in order to be able to manipulate tissue and bear loads in anatomically confined spaces.

  • Patent number: 11484473
    Abstract: A capsule shredding device is provided, which includes first and second housing sections. The first housing section has a chamber slightly larger than the capsule located in one end of the housing section so that when the capsule is seated in the chamber it cannot freely rotate in the chamber. A vial is releasably coupled to other end of the first housing section. One or more passageways extend from the bottom of the chamber toward the other end of the second housing section. The second housing section has an internal chamber with a spike extending into the chamber integrally formed on the interior upper section of the housing section. When the two housing sections are threaded together such that are drawn towards each other, the spike pierces the capsule, and upon further rotation the spike shreds the capsule thereby releasing the powder contained therein which flows through the one or more passageways into interior of the vial.

  • Patent number: 11484465
    Abstract: This disclosure relates to device for providing continuous negative abdominal pressure (CNAP) which selectively recruits (inflates) the dorsal (spinal region) collapsed areas of the lung, while enabling the patient to remain in the supine (usual) position. The CNAP device includes a rigid frame configured to have a shape and size to envelop a patient's lower chest and abdominal area while in a supine position with the frame having opposed edges which sit on a surface on which the supine patient is resting. A series of panels are mounted in the frame such that the series of panels extend around the patient's lower chest and abdominal area. A flexible sheet wrapped around the outside of the panels and is long enough to extend up to the patient's upper chest and down to the patient's thighs and wide enough to envelop the supine patient's lower chest and abdominal area.
