Needle types

NeoNavia offers the two needle types most used today in ultrasound-guided biopsies as well as an innovative third needle type which is specifically intended for technically challenging tissue sampling. NeoNavia can thus replace all other ultrasound-guided biopsy systems in a clinic. All three needle types are powered by our patented pulse technology.

FlexiPulse – an open front-loaded core needle

The FlexiPulse needle is intended for ultrasound-guided breast biopsy and particularly well suited for technically challenging biopsies such as in axillary lymph nodes and dense breast tissue.1 The open front-loaded needle has been developed for maximum tissue yield with the least possible damage to surrounding tissue.2 In pre-clinical studies, the FlexiPulse needle has provided larger samples than current core needles. 3

Design and features:

  • The outer cannula is shaped as an open, hollow front-loaded tube with a slightly sharpened inside edge.
  • The inner solid part has a sharp tip.
  • The needle diameter is 14G.
  • The sampling chamber size is 30 mm.
  • All needle functions are controlled via buttons that are activated on the hand-held driver.



CorePulse – a core needle with pulse control

CorePulse is NeoNavia’s version of a core needle with pulse control and is intended for ultrasound-guided breast biopsies. CorePulse belongs to the Core Needle Biopsy (CNB) category (read more about CNB) but differs in some important aspects such as needle insertion, placement in a suspicious lesion, and in the actual sampling situation.

Design and features:

  • The inner cannula has a side-notch like other core needles.
  • The outer cannula is spring-loaded.
  • The needle diameter is 14G.
  • The sampling chamber size is 20 mm.
  • The pulses enable precise placement in the lesion.
  • Sampling is automated and requires no manual spring loading.
  • All needle functions are controlled via buttons that are activated on the hand-held driver.



VacuPulse – a vacuum-assisted pulse biopsy needle

VacuPulse is NeoNavia's vacuum-assisted biopsy (VAB) needle, intended for ultrasound-guided breast biopsy. VacuPule is also operated with pulse technology which enables a controlled stepwise needle insertion through the tissue and a precise placement in the lesion.

Design and features:

  • The outer cannula has a side-notch.
  • The inner cannula acts as a cutter.
  • The needle diameter is 10G.
  • The sampling chamber size is 20 mm.
  • By using the vacuum function, multiple samples can be collected with a single incision. The samples are collected in a sample container at the underside of the handset.
  • All needle functions are controlled via buttons that are activated on the hand-held driver.
