ORANGEBURG, N.Y., Nov. 6, 2013 (GLOBE NEWSWIRE) -- Vision-Sciences, Inc. (Nasdaq:VSCI) announced today the publication of positive outcomes of a clinical study that evaluated the durability and microbial barrier properties of the Company's EndoSheath ® technology in the flexible cystoscopy setting in the November issue of the peer-reviewed journal BMC Urology. To assess the efficacy of Vision-Sciences' EndoSheath technology with flexible cystoscopes, study authors tested the barrier integrity of each EndoSheath disposable following clinical procedures and then performed microbiology sampling of the flexible cystoscopes to determine if any bacterial contamination had occurred. Study outcomes and conclusions include:
- 100% of EndoSheath units tested were leak-free following clinical use. This finding confirms outcomes of a prior study of 875 endoscopic procedures in which no leaks were reported.
- 100% of microbiology samples showed a clean flexible cystoscope following EndoSheath technology usage and the Company's recommended cleaning procedure.
- The study authors concluded that Vision-Sciences' reprocessing procedure featured a low risk of pathogen transmission, high-patient safety and a valid alternative to the recommended high-level disinfection procedure of competitive flexible cystoscopes.
The number of colony forming units ("CFU") from the samples was counted after 72 hours and then divided into three categories: Clean FC ( < 5 CFU/sample); Critical FC (5-50 CFU/sample); and High-risk FC ( > 50 CFU/sample). This result was compared with data of 10 years continuous control sampling recorded in the Copenhagen Clean-Endoscope Quality Control Database ("CCQCD") and analyzed with a Chi-square test for homogeneity.All samples obtained after removal of the EndoSheath and after cleaning and alcohol disinfection, both from the maneuver part and insertion part of the FC, showed a Clean FC with a mean of 0.2 CFUs; the few bacteria identified originated from skin commensals, and were found in a few samples taken both before and after reprocessing the FC. As no leak was detected, study authors concluded that the contamination likely resulted from the handling of the FC or from sampling procedures. Leak testing during the study utilized a pressure decay system (Uson, Houston, TX).
