title: Bone-marrow biopsy needle incorporating a snare-coil specimen-capturing device: description and preclinical studies.
abstract: A tissue biopsy needle maximizes adequate specimen retrieval and minimizes patient pain and tissue disruption. The proposed biopsy needle incorporates an internal snare-coil for capturing specimens. The snare-coil device is described along with needle durability and performance testing. Sharply cut, nonfragmented, cored specimens were retrieved from a resin-based foam. In clinical practice, the snare-coil technology may minimize post-insertion needle manipulations and patient pain. Further studies are required to determine the impact of snare-coil needles on the retrieval of adequate specimens from patients.
