Area of Science:

  • Hematology
  • Medical Devices
  • Pathology

Background:

  • Bone marrow biopsy is crucial for diagnosing hematologic disorders.
  • Traditional methods can involve complex specimen retrieval and manipulation.
  • Minimizing needle manipulation and improving specimen recovery are key goals.

Purpose of the Study:

  • To evaluate the efficacy of the SNARECOIL needle for bone marrow biopsy.
  • To assess the quality and length of specimens retrieved by the SNARECOIL needle.
  • To determine the impact of the SNARECOIL needle on diagnostic capabilities.

Main Methods:

  • The SNARECOIL needle, featuring an internal capturing coil, was used in 50 bone marrow biopsy procedures.
  • Procedures were performed on 44 patients for various hematologic indications.

  • Specimen length and architectural integrity were analyzed.

    • Main Results:

    • The SNARECOIL needle successfully retrieved bone marrow specimens in all procedures.
    • Average specimen length was 2.1 cm, with 52% measuring >= 2.0 cm.
    • The majority of specimens showed intact marrow architecture, enabling pathologic diagnosis in every case.

    Conclusions:

    • The SNARECOIL bone marrow biopsy needle reliably retrieves intact bone marrow core specimens.
    • The device facilitates specimen recovery and minimizes postinsertion needle manipulation.
    • The SNARECOIL needle is effective for obtaining specimens suitable for pathologic interpretation.
