State of the Art Stent Design:

  • Slotted Tube
  • Closed Cell 
  • Diameter Specific
  • Thin-Strut

Volo features a Closed Cell, Diameter-Specific, Thin-Strut Design for improved clinical outcome combined with well proven SDS (Avion derived) for an easy and safe delivery.

Volo coronary stent system consists of a slotted tube stent platform premounted on a RX balloon Stent Delivery System. The stent's closed cell design is based on a unique harmonic interconnection of multiple mono type cells featuring excellent mechanical properties: 

  • Uniform and predictable mechanical behaviour under bending; stent bends smoothly and homogeneously both in the premounted as well as in the expanded status. Local strut detachment is prevented even under extreme bending without compromising the profile with flaring or fish scaling effects 
  •  In the expanded status, thanks to the uniform and symmetric design, bending deformations (curves) keep consistent and predictable no matter which is the stent orientation and the degree of the bending. Cells maintain their average size without widening or overlapping thus maintaining an effective and reliable scaffolding in every situation

Diameter Specific design

Volo is laser cut from different sized stainless steel tubes depending on the final stent expansion diameter: 2.50, 2.75 and 3.00 mm stents are obtained from small diameter tubes while 3.50 and 4.00 mm stents are obtained from larger diameter tubes. The result is a 15% metal to artery ratio with minimum (less than ± 1% ) variation inside the whole expansion range.

Thin Struts

Volo's strut thickness has been set as low as 80 Micron (0.0031'') in the small diameters of 2.50, 2.75 and 3.00 mm while measures 98 Micron (0.0038'') for the larger diameters (3.50 and 4.00 mm).

Special Tight Fix™ crimping process, while contributing to lower the stent crossing profile, has led to unmatched stent retention force (bench test data on file) making of this system a real safe and effective tool for challenging and 'extreme' stenting.
While high conformability has been reached in Volo's closed cell design stent thanks to a careful combination of cell design, dimensioning, low strut thickness, even higher flexibility of the crimped stent has been achieved also thanks to a superb, well proven SDS which results from a specifically 'tuned' Avion PTCA balloon catheter.
The combination of SDS proximal Hypotube (2.0 F) design and the special TAP™ (Tapered coaxial) distal shaft construction eliminates typical jump in push and torque transmission occurring in conventional Hypotube design SDS. This right progression from pushability to flexibility in the distal shaft, one of the keys of success for an easy lesion reaching and crossing, is obtained with a defined and tested thickness tapering in the distal shaft from the hypotube end down through the catheter tip. This maintains the flexibility of the very distal part of the catheter without compromising the overall pushability. As a result optimal push and pull control is guaranteed. Highly stable coaxial joint between the hypotube and the distal shaft finally provides optimal torque control.
