A new flow-based design for double-lumen needles [PDF]
Journal of Biomechanics 160, 111832, 2023, 2023 Oocyte retrieval forms a crucial part of in vitro fertilisation treatment and its ultimate outcome. Standard double-lumen needles, which include a sequence of aspiration and flushing steps, are characterised by a similar success rate to single-lumen needles, despite their increased cost.
