Pre-surgical Pulmonary Nodule Localization Coil (20150351, Dr. Michael Rosenberg)
Localization coil moves with patient’s respiratory cycle
A pre-surgical pulmonary nodule localization coil system moves with a patient’s respiratory cycle, allowing the patient normal respiration without dislodging the device prior to surgery. The localization coil system has two components:
- Coil portion. The coil is configured to be arranged within a lung, and it fixes itself within the desired position of the lung (i.e., in or near a nodule or tumor).
- Suture portion. A suture attached to the proximal end of the coil, configured to be arranged in a pleural space, traverses the pleura and tract to the skin. The suture retracts freely with respiration, preventing any traction on the coil portion in the lung.
The localization coil is pre-loaded into a delivery needle, and a pusher rod inside the needle deploys the coil and allows the needle to retract without affecting the coil. Once deployed, both the spring-like coil and the suture keep the device in position and allow normal respiration. The device also helps a surgeon more easily locate the suture within the pleural space and simply follow the suture down to the coil.
Significantly simplifies coil deployment
Current localization coils often become dislodged due to lung movement during patient respiration. Other localization methods using guidewires or metal coils risk injuring patients with large or complex structures, such as hooks or barbs, at the site of the lung nodule. With this technology, the suture at the proximal end of a coil prevents the coil from dislodging from during the procedure. The design significantly simplifies deployment by reducing time and radiation exposure and increasing accuracy of localization.
Phase of Development
- Simplifies deployment procedure, reduces time and radiation exposure and increases accuracy
- Easy to remove
- Helps surgeons more easily locate the suture within the pleural space
- Localization coil with suture moves with a patient’s respiratory cycle, allowing normal respiration
- Attached suture keeps the device in position
- Pre-surgical localization of lung and other nodules or masses
- Pre-surgical planning, particularly for breast cancer
- Localization of masses or tumors in other parts of the body (e.g. breasts, other organs) where patient movement may cause dislodgment
