Intended Use

The SpyGlass DS Direct Visualization System is indicated for use in diagnostic and therapeutic applications during endoscopic procedures in the pancreatico-biliary system including the hepatic ducts.

The SpyGlass DS Direct Visualization System comprises two components: the SpyScope DS Access and Delivery Catheter and the SpyGlass DS Digital Controller.

The SpyScope DS Access and Delivery Catheter is intended to provide direct visualization and to guide both optical and accessory devices for diagnostic and therapeutic applications during endoscopic procedures in the pancreatico-biliary system including the hepatic ducts.

The SpyGlass DS Digital Controller is intended to provide illumination and receive, process, and output images from the SpyScope DS Access and Delivery Catheter for diagnostic and therapeutic applications during endoscopic procedures in the pancreatico-biliary system including the hepatic ducts.

Device Description

The SpyGlass DS Direct Visualization System comprises two components: (1) the sterile, single-use SpyScope DS Access and Delivery Catheter ("Catheter") and (2) the SpyGlass DS Digital Controller (the "Controller").

The Catheter is a flexible video cholangiopancreatoscope, introduced into the pancreatico-biliary system via a duodenoscope. The Catheter comprises a handle, an insertion tube, and a connection cable. The handle includes two articulation control knobs, a lever to lock the control knobs in place, connectors for irrigation and aspiration, a working channel port, and a strap to attach the Catheter to a duodenoscope. The insertion tube contains one working channel for accessory devices and aspiration, two channels for irrigation, two optical fibers to transmit illumination from the Controller, and wiring to transmit video signals to the Controller. The bending section at the distal portion of the insertion tube is controlled by the user via the articulation control knobs on the handle. The distal end of the insertion tube contains an imaging sensor for capturing video and transmitting it to the Controller, elements for transmitting illumination from the Controller, and the distal openings of the irrigation and working channels. The connection cable connects the Catheter handle to the Controller for transmitting illumination and video signals.

The Controller is an endoscopic video imaging system that combines the functionality of a camera and an LED light source. The Controller receives video signals from the Catheter, processes the video signals, and outputs video images to an attached monitor. The Controller also generates and controls the illumination transmitted to the distal end of the Catheter. The user interface of the Controller comprises a power button, a receptacle to connect the Catheter connection cable, buttons to turn illumination on or off and to control the illumination intensity, and an illumination intensity indicator. The Controller outputs video images to an attached monitor via DVI, VGA, or S-Video ports, and the user may select NTSC or PAL video formats according to the geographic region of use.

AI/ML Overview

The document provides a 510(k) summary for the Boston Scientific SpyGlass DS Direct Visualization System. It details the device's indications for use, technological characteristics, and a summary of performance data to establish substantial equivalence to predicate devices. However, it does not explicitly state "acceptance criteria" in a numerical or categorical format, nor does it present the study results in a way that directly maps to pre-defined acceptance criteria for performance metrics.

Instead, the document generally states that "All evaluation acceptance criteria were met" for specific tests. It also notes that performance testing (bench) was "successfully completed to establish substantial equivalence."

Given the information provided, here is an attempt to synthesize the requested information, acknowledging the limitations in explicit quantitative acceptance criteria or detailed study results within this summary:

2. Sample Size Used for the Test Set and Data Provenance

The document refers to "Non-clinical testing" and "Performance testing (bench)." It does not specify a "test set" in terms of patient data or samples from a clinical trial. The testing appears to be primarily bench testing on the device itself (e.g., measuring physical dimensions, optical performance, mechanical reliability) and biocompatibility testing on material samples. Therefore, there is no patient-specific test set or data provenance (country of origin, retrospective/prospective) described in this summary.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications

Not applicable. The described testing is non-clinical bench testing and biocompatibility. Clinical ground truth as established by experts is not described for these tests.

4. Adjudication Method for the Test Set

Not applicable. There is no mention of a human-adjudicated test set.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, and its effect size.

No, an MRMC comparative effectiveness study is not mentioned in this 510(k) summary. The study described is non-clinical bench testing.

6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done.

Yes, the studies described are standalone performance tests of the device itself (algorithm/system only, without a human specifically "in-the-loop" for performance evaluation against ground truth derived from expert opinion). The "performance data" focuses on the technical specifications and safety of the device components.

7. The Type of Ground Truth Used

For the engineering and device performance aspects (e.g., diameter, resolution, frame rate, articulation), the "ground truth" would be the device's design specifications and industry standards. For biocompatibility, the "ground truth" is established by validated biological assays and ISO standards. For electrical safety and EMC, it's compliance with IEC standards. There is no mention of expert consensus, pathology, or outcomes data as "ground truth" in the context of the described non-clinical studies.

8. The Sample Size for the Training Set

Not applicable. As a physical medical device, not an AI/ML algorithm, there is no training set in the conventional sense of machine learning. The device's design and manufacturing processes are developed based on engineering principles and previous device experience.

9. How the Ground Truth for the Training Set was Established

Not applicable, as there is no training set mentioned in the context of this traditional medical device submission.
