Implantable Sensor Staple for Anastomotic Leak Detection

The patent applies preliminary action by implanting sensors during the surgical procedure itself, before the patient is discharged. These sensors continuously monitor physiological parameters at the anastomosis site from the outset, enabling detection of leakage in its earliest stages rather than waiting for clinical symptoms to manifest. This transforms the detection approach from reactive (waiting for symptoms) to proactive (continuous early monitoring).

The patent replaces the mechanical/clinical monitoring system (relying on physical signs like fever, white blood cell count, and abdominal tenderness) with an electronic sensing system. The sensors directly measure physiological parameters such as temperature, pH, and electrical properties at the anastomosis site, providing objective, continuous data that is not dependent on clinical judgment or patient presentation, thereby eliminating the lag time inherent in clinical sign monitoring.

The patent extracts the detection function from complex external imaging systems and relocates it to simple, implantable sensors positioned directly at the anastomosis site. Instead of using fluoroscopy or other resource-intensive imaging modalities that require external equipment and radiation, the sensors continuously measure local physiological parameters (temperature, pH, electrical properties) providing sensitive leakage detection without the need for complex imaging infrastructure.

The patent employs disposable, implantable sensors that are inexpensive compared to imaging modalities. These sensors are designed for single-use, providing cost-effective continuous monitoring during the critical postoperative period. The sensors are implanted during surgery and then discarded after serving their monitoring function, eliminating the need for expensive reusable imaging equipment and reducing overall system cost while maintaining high detection sensitivity.
