SpyGlass DS II System & AUTOLITH® TOUCH Biliary EHL System
The Northgate Technologies, Inc. AUTOLITH® TOUCH unit is a software controlled, electronic device capable of cracking large stones. The objective is to reduce the size of the stones so that fragments can be removed without major surgery. The AUTOLITH® TOUCH unit is designed to be used with Northgate Technologies, Inc. bipolar disposable EHL probes for the fragmentation of biliary stones.The AUTOLITH TOUCH Biliary EHL System is distributed by Boston Scientific.
The AUTOLITH TOUCH 1.9Fr., 375cm EHL probe is a single-use device to be used with the AUTOLITH TOUCH Biliary EHL Generator. The EHL probe, when used with the SpyGlass II DS System, helps to manage large biliary stones.
Stone Management
- The ASGE describes difficult stones as those that are: Large (>10 mm), Unusually hard or eccentric in shape, Located in an abnormal distal duct (oblique, narrowed, difficult angulation), or Impacted or present in high multiplicity. These factors can make stones refractory to extraction.2
- The rate of clearance of difficult biliary stones in a single-session ERCP using SpyGlass™ Direct Visualization System has been shown to be greater than 70%.1
- The SpyGlass™ Retrieval Basket is a durable 4-wire nitinol basket designed to grasp and remove biliary and pancreatic stones and stone fragments while maintaining its shape in a difficult anatomy.
- Achieving single-session stone clearance and reducing the need for a repeat procedure may deliver greater patient satisfaction and decrease additional procedural costs.8
Stricture Management
- Performing biopsies under direct visualization using the SpyGlass DS System and Legacy SpyBite Biopsy Forceps may enable more definitive diagnosis of malignancies through increased sensitivity compared to brush cytology.3, 4
- SpyBite Max Biopsy Forceps – a design enhancement to the Legacy SpyBite Biopsy Forceps - has been shown to acquire on average more than 2X tissue per bite.5
- Studies have shown that the SpyGlass™ Direct Visualization System impacted clinical management and diagnostic procedures in more than 85% of patients evaluated.6, 9
- The SpyGlass Retrieval Snare is designed to efficiently capture and remove foreign bodies – such as migrated plastic stents – in the biliary and pancreatic ducts.
