Description

PROJECT SUMMARY ABSTRACT The goal of this small business innovation research grant is to develop and commercialize a cost effective contrast assisted intraoperative ureter detection system which integrates into existing surgical tools to identify ureters in real time and prevent iatrogenic injuries of iatrogenic ureteral injuries are detected postoperatively up to days after hospital discharge These injuries can cause ureteral obstruction fistula e and eventually renal failure when not repaired immediately and cost hospitals an average of $ per patient with an added hospitalization time of days Currently the only available technologies that assist in ureter detection including cystoscopy and lighted stents are costly and have led to additional complications such as reflux anuria and urinary tract infections The RUD system would be the first unobtrusive and cost effective alternative with the potential to decrease the incidence of ureteral complications during surgery In this SBIR project Briteseed will continue the development of a ureter detection system and validate its capabilities in both ex vivo and in vivo porcine studies This rapid ureter detection RUD system will use optical technology to non invasively detect the ureters in real time and prevent iatrogenic injury during surgery This system will enable users to detect the ureters using methylene blue MB an FDA approved and clinically utilized dye as a contrast agent during surgery No additional tools such as catheters stents and cystoscopy will be used therefore avoiding any complications caused by these tools By preventing ureteral injury through real time detection this technology will lead to safer surgical outcomes for patients and lessen the financial burden on hospitals In Phase I of the SBIR the RUD system will be optimized and validated to provide a real time automated ureter detection and b ability to differentiate between the ureter and surrounding tissues In Phase II the RUD system will be modified to integrate into surgical tools most commonly used near the ureters during gynecological procedures i e thermal ligature devices grasper dissectors This technology will profoundly affect gynecological procedures where the ureter is at high risk with no highly adopted detection method currently available to prevent injury PROJECT NARRATIVE Studies have shown that of iatrogenic ureteral injuries are detected postoperatively up to days after hospital discharge These injuries can cause ureteral obstruction fistula e and eventually renal failure when not repaired immediately and cost hospitals an average of $ per patient with an added hospitalization time of days Currently the only available technologies that assist in ureter detection including cystoscopy and lighted stents are costly and have led to additional complications such as reflux anuria and urinary tract infections This SBIR project aims to develop and commercialize the Rapid Ureter Detection RUD system which would be the first unobtrusive and cost effective alternative with the potential to decrease the incidence of ureteral complications during surgery
