SpyGlass™ DS II Direct Visualization System

featuring Sight Shield Technology

Innovative tools to see, diagnose, and treat

The SpyGlass DS II Direct Visualization System includes an expansive portfolio of devices that deliver innovative diagnostic and therapeutic approaches to biliary stone and stricture management ­– all to help drive successful outcomes in complex endoscopic retrograde cholangiopancreatography (ERCP) cases. These accessories may also help to define pre-surgical mapping and the inspection of tissue before and after ablation procedures.
SpyGlass DS II tool family

SpyBite™ Max Biopsy Forceps

Helps enable greater tissue acquisition* which may result infaster more accurate diagnosis of malignancies.3

SpyGlass™ Retrieval Basket

A durable 4-wire nitinol basket designed to grasp biliary and pancreatic stones while maintaining its shape in adifficult anatomy.

SpyGlass™ Retrieval Snare

Designed to efficiently capture and remove foreignbodies – such as migrated plastic stents – in the biliaryand pancreatic ducts.

SpyGlass DS II System & Autolith Touch Biliary EHL System

Boston Scientific and Northgate Technologies, Inc., work together to provide physicians and hospitals with access to the the Autolith Touch Biliary EHL System and accessories. All system components can be obtained directly from Boston Scientific, which provides an efficient ordering process, first-rate customer support and expanded options for stone management.

The Autolith Touch 1.9Fr., 375cm EHL probe is a single-use device to be used with the Autolith Touch EHL Generator. The EHL probe, when used with the SpyGlass II DS System, helps to manage large biliary stones.

Stone Management

The SpyGlass DS II System, combined with the Autolith™ Touch Biliary Electrohydraulic Lithotripsy (EHL) System or other lithotripsy devices, provides the capability to fragment large biliary stones under direct visualization and enable a high stone clearance success rate in single session treatments.1
  • Approximately 10-15% of biliary stone cases are considered difficult and cannot be treated effectively using standard ERCP techniques.
  • Direct visualization stone clearance using EHL has been shown to be clinically effective with demonstrated procedural success, with single-session stone clearance rates of 74.5%.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.

Stricture Management

When used during an ERCP procedure, the SpyGlass DS Direct Visualization System with Sight Shield Technology enables direct visualization of the bile and pancreatic ducts and can help perform biopsies, diagnose indeterminate strictures, and remove foreign bodies such as migrated biliary and pancreatic plastic stents.
  • Performing biopsies under direct visualization using the SpyGlass DS II System and SpyBite™ Biopsy Forceps may enable faster, more accurate diagnosis of malignancies compared to brush cytology: 86% sensitivity compared to 45%.3,4  
  • SpyBite Max Biopsy Forceps – a design enhancement to the original SpyBite Biopsy Forceps – have been shown to acquire more than 2X tissue in an average bite.5
  • In a clinical study of 289 patients, clinical management was altered in 85% of patients undergoing diagnostic ERCP with cholangioscopy, and the study showed high procedural success and high accuracy in helping to diagnose indeterminate strictures.6
  • The SpyGlass Retrieval Snare is designed to efficiently capture and remove foreign bodies – such as migrated plastic stents – in the biliary and pancreatic ducts.

Facilitating Ablation Procedures

When used in conjunction with the Habib™ EndoHPB Bipolar Radiofrequency Ablation Catheter and metal stent placement, the SpyGlass DS II System may be a useful tool to help confirm ablation size and location when used before and after the procedure.*

Presurgical Mapping

A clinical study of 118 patients examined the role of digital cholangiopancreatoscopy technology in “mapping” the extent of malignant involvement in the biliary or pancreatic ducts before surgical intervention. The analysis demonstrated that the surgical plan was altered in 34% of cases when using the SpyGlass DS II Direct Visualization System.7
