Wrap Spring Clamp

A clamp with helical coils or springs to receive and secure cylindrical rods; e.g., for external fixators. The clamp includes quick connection and tightening around the rod . These clamps have multiple uses including use as a device for securing a bone, scaffolding, and other applications where gripping 360 degrees around the rod offers significant advantage.

System for Determining the Orientation of a Bone-Implanted Anchor

A method for simplifying the process of designing a platform for minimally invasive surgery. The platform is designed to attach to a set of bone-implanted anchors attached to the patient. This method makes the fitting of the platform to the anchors simpler and easier.

Microcatheter with Auxiliary Parachute Guide Structure

A microcatheter with a deployable parachute attached to its distal tip: The parachute in its retracted position lies flush against the exterior wall of the distal segment of the catheter. Control strings, cables or wires traverse the length of the microcatheter through channels within its wall and exit through strategically placed apertures at the tip of the microcatheter to attach to the parachute. When the parachute is deployed, the microcatheter is guided by blood flow or jets of liquid that are injected through the microcatheter. When the parachute is retracted, the microcatheter may be used with a guidewire to superselect vasculature. The microcatheter device has multiple uses permitting diagnostic and therapeutic superselective angiography.

Solid-State Erbium Laser Surgical Cutting Probe

The present system developed by Vanderbilt researchers provides a combination of a base laser pump connected to a laser surgical probe via a connection assembly. The surgical probe has a disposable tip wherein the Er:YAG lasing occurs. This system is useful in laser surgeries involving high precision and appropriate power levels. In particular, intraocular surgeries could benefit from the use of such a system.

System for Determining the Orientation of a Bone Implanted Post

A method for determining an orientation of a base to which a fiducial marker is detachably mounted. The method includes the steps of determining the axis of symmetry for the fiducial marker and choosing the determined axis of symmetry of the fiducial marker as the axis of symmetry of the base.

Optical Injector: A Novel Device for Airway Injection

Vanderbilt researchers have a novel optical injector that combines the injection apparatus with an endoscope, thereby allowing the surgeon to have a free hand for manipulation of tissues around the injection site without having to use an operating microscope.

Transductive Access Catheter

The tissue of the human body is separated by planes separated by minimal fluid, and it is often desirable to enter into the space between these planes to perform procedures including delivery or removal of fluid/therapeutics. Accurately and harmlessly placing catheters within these planes is very difficult because of the very close proximity of the tissues -- often within 1mm. The Transductive Access Catheter System solves these problems by allowing the operator to insert a shallow beveled needle into the space of interest using a hollow inner catheter that is filled with saline to probe much like a micro water hammer to detect difference in resistance to flow at the tip of the catheter. The primary competing technology uses suction to pull on the outer tissue which increases the target space volume at the catheter; however this has limitations of tissue rigidity and thickness (PerDUCER, Comedicus). Due to the versatility across disciplines, a wide variety of applications for this catheter exist, which include: Pericardial Space Infusion or Drainage, Pleural Space Infusion or Drainage, Subdural and Epidural Infusion, and Intraocular Fluid Space Infusion or Drainage.

Point of Care Device for Confirmation of Intravenous (IV) Catheter Placement and Measurement of Peripheral Venous Pressures

Vanderbilt researchers have designed a low-cost, point-of-care device that non-invasively monitors peripheral venous pressure (PVP) to ensure proper placement of peripheral intravenous (PIV) catheters in patients. Use of this device will ensure proper administration of intravenous fluids and intravenous drugs. The device will also prevent the administration of fluid and potent pharmacologic agents into the subcutaneous tissue or fascia, commonly known as "IV infiltration."

Collapsible Lightweight PortableLeg Holder for Ultrasound GuidedLateral Popliteal Block Procedures

A Vanderbilt team led by anesthesiologist Dr. Rajnish Gupta has developed a collapsible, lightweight and portable patient leg positioner for secure and stable leg positioning during ultrasound guided nerve block anesthetic procedures.
