Medical Devices - Endoscopic Ultrasound : Endoscopic ultrasound (EUS) is a medical procedure that combines endoscopy and ultrasound to obtain detailed images of the digestive tract and surrounding tissues. It involves inserting an endoscope with an ultrasound probe into the digestive tract, allowing physicians to visualize and assess conditions such as tumors, cysts, and other abnormalities within the gastrointestinal tract, pancreas, and nearby organs. EUS is commonly used for diagnostic purposes and to guide fine-needle aspiration for tissue sampling.

2. About Device Endoscopic Ultrasound (EUS) is a minimally invasive medical imaging technique that combines endoscopy and ultrasound to visualize and evaluate internal organs and structures within the gastrointestinal (GI) tract.

3. Clinical Uses Tumor Staging: Accurate assessment of GI tumors and determining their extent and involvement of adjacent structures. Esophageal Cancer: Staging and evaluation of esophageal tumors and lymph nodes.

4. Tissue Sampling: Performing fine-needle aspiration (FNA) or biopsy to obtain samples for diagnostic evaluation. Pancreatic Disorders: Diagnosis and management of pancreatic cysts, tumors, and chronic pancreatitis.

5. Working Principle Endoscopy: A flexible endoscope with a built-in ultrasound transducer is inserted into the GI tract through the mouth or anus. Ultrasound Imaging: The transducer emits high-frequency sound waves that penetrate the surrounding tissues and bounce back as echoes.

6. Dual-Mode Imaging: The device displays real-time images from both the endoscope and ultrasound transducer simultaneously. EUS-Guided Procedures: The device can be used to guide interventions such as FNA, drainage, and injection.

7. Performance / Efficiency High-Resolution Imaging: Provides detailed and clear images, allowing for precise visualization of small structures and abnormalities. Real-time Visualization: Enables immediate evaluation of tissues and facilitates on-the-spot decision-making during procedures.

8. Minimally Invasive: Reduces patient discomfort, risk, and recovery time compared to traditional surgical methods. Accurate Staging: Allows precise determination of the extent of tumors and involvement of adjacent organs, aiding in treatment planning.

9. Competitive Products Laparoscopic Ultrasound (LUS): Utilizes laparoscopic instruments with an attached ultrasound probe for abdominal imaging during surgery. Computed Tomography (CT) Scan: Provides cross-sectional images of the abdomen and chest, valuable for preoperative assessment and staging. Magnetic Resonance Imaging (MRI): Offers detailed soft tissue imaging without ionizing radiation, suitable for evaluating certain GI conditions. Endoscopic Confocal Laser Endomicroscopy (CLE): Provides microscopic imaging during endoscopy, aiding in real-time tissue characterization.
