Importance of GC

Most Important Factors
Back up support
Anti Heat Deformation
Safety
Maneuverability
These factors are essential for stable procedures, especially in long,
complex cases.

Current trend
Catheter with stiff shaft
Strong back up support due to its rigidity
Concern about safety due to tip stiffness
Catheter with soft shaft
Safe due to soft tip
Extra attention needed to get better back up support

Product Concept
- Realizes all the essential characteristics for a
guiding catheter – both back up support and safety.
Creating a stable environment for the doctors to
concentrate on PCI treatment
*Most conventional guiding catheters can be divided into two types: those
that have a rigid shaft and tip which undermines safety, and those that have
a flexible shaft and tip which sacrifices the stability of the procedure.
However, the Hyperion realizes both safety and backup support.

Maneuverability

Backup Support - Hyper shaft
Focusing on flexibility of the tip, soft resin material is applied in
Hyperion. While resin normally gets deformed due to heat,
ASAHI’s unique technology enables the catheter to have flexibility,
back up support, and anti-heat deformation.

Backup Support ～anti- heat deformation～
Test Method:
The curve is extended in warm water to a shape as if it is engaged, and the
catheter tip is fixed onto the axis of the force gauge. The back-up support
is evaluated by measuring the change of force in certain time intervals (0-
120 mins)

Backup Support ～2nd curve～
2nd curve with high rigidity provides good
retention of the curve.

Backup Support ～3rd curve～
Unique curve proximal to 2nd curve provides stable
backup support by increasing the area of the catheter
in contact with the aorta wall.

Maneuverability –HENKA-Braid
Unlike conventional guiding catheters, Hyperion’s shaft
is braided differently at the proximal and the distal area.
⇒ - enables transmission of the push force
- prevents backing out of the catheter
