PoleVault™

Download PoleVault Brochure

PoleVault™ is a hypotube specifically designed to optimise catheter performance. Improve hypotube kink resistance from 10% to 40% without compromise of push, track, torque or flexibility.

  • Increase interventionalist confidence in your product
  • Reduce patient risk
  • Maximise catheter revenue

 

PoleVault™ Features

PoleVault™ Features

  • Improved hypotube kink resistance of 10% to 40% without compromise of track, push or torque
  • Maintain current kink resistance while increasing hypotube internal diameter
  • Improved hypotube resilience leading to no package set on removal from dispenser
  • Improved “feel and balance” of the hypotube shaft from an optimisation of strength and ductility

 

PoleVault™  Technical Data

Tensile stress/strain

Tensile stress/strain curves for a conventional (304 SS) and PoleVaultTM hypotube. The PoleVaultTM exhibits notably higher elongation (8%) while the yield strength values of both hypotubes are comparable: 153 kpsi and 156 kpsi respectively.

Kink Resistance

Kink test force/displacement curves exhibited by a conventional hypotube and a PoleVault TM hypotube. The hypotubes have an identical wall thickness/outerdiameter ratio and comparable yield strengths. The kink test comprises a compression loading of an arched hypotube between two parallel plates as per European Standard EN 13868. The test rate was 2 in/minand the start distance between the test plates was 3 inch. Kink test force/displacement curves exhibited by a conventional hypotube and a PoleVault TM hypotube. The hypotubes have an identical wall thickness/outerdiameter ratio and comparable yield strengths. The kink test comprises a compression loading of an arched hypotube between two parallel plates as per European Standard
EN 13868. The test rate was 2 in/minand the start distance bet    Kink resistance, 1/k, dependence on the wall thickness (WT)/outerdiameter (OD) ratio for conventional and PoleVaultTM hypotubes,exhibiting comparable yield strength levels. The kink value, k, is a distance between the plates at the moment of a forcedrop (“knee” formation) recorded on the force/plate displacement curve.een the test plates was 3 inch.

Shape Set Resilience

Comparison of the shape set resilience/kink resistance performance characteristics for two sets of conventional and PoleVault hypotubes. Each set of hypotubes has a different wall thickness (WT)/outer diameter (OD) ratio. The shape set value, h, is defined as a maximum deflection from a straight edge exhibited by a 1 m long hypotube after its storage in a 6 inch diameter coil for two hours.
