A novel amniocentesis needle enhances visualization during ultrasound guidance. Its design with side holes aims to minimize unsuccessful aspirations, improving procedural accuracy.

Area of Science:

  • Medical Devices
  • Obstetrics & Gynecology
  • Diagnostic Imaging

Background:

  • Amniocentesis is a common prenatal diagnostic procedure.
  • Clear visualization of the amniocentesis needle during ultrasound is crucial for safety and efficacy.
  • Reducing "dry taps" (unsuccessful aspirations) is a key goal in improving the procedure.

Purpose of the Study:

  • To introduce and evaluate a novel amniocentesis needle designed for improved sonographic depiction.
  • To assess the effectiveness of the needle's side port design in reducing "dry taps".

Main Methods:

  • Development of a new amniocentesis needle with side holes in the aspiration cannula.
  • Design of side port diameters to match the wavelength of a 3.5-MHz ultrasound beam.
  • Evaluation of needle imaging quality and diffraction patterns using real-time ultrasound.

Main Results:

  • The new needle design allows for clearer depiction during sonographic monitoring.
  • Side holes facilitate improved imaging, even outside the transducer focal plane.
  • The needle's diffraction pattern is clearly visualized, aiding in precise needle placement.

Conclusions:

  • The novel amniocentesis needle offers enhanced visibility under ultrasound guidance.
  • The design modifications contribute to potentially reducing procedural complications like "dry taps".
