Needles feature a modified tuohy point designed to provide enhanced tactile feel.
Their short point length minimises accidental dural puncture. These needles are slightly sharper than tactile needles for penetrating tough tissue, and the needle heel is specially designed to minimize catheter shearing. Calibrated needle depth markings assist in awareness of needle placement without interfering with tactile feedback. A unique, fitted one-piece plastic stylet prevents tissue coring.
