Hydrophilic Introducer Set — 4 to 7 F, up to 23 cm
SKU: XY-HIS | Set Introductor Hidrofílico — 4 a 7 F, hasta 23 cm
The hydrophilic introducer is the access family's upgrade tier: the sheath carries a hydrophilic coating along its whole outer length which, activated with saline, markedly reduces insertion force and — the part less talked about — withdrawal force, which in radial work is the spasm moment. Made in 4 to 7 F with lengths of 7, 11, 16 and 23 cm: the 23 cm is the long radial sheath that reaches past forearm tortuosity and doubles as a supporting mini-sheath. Each set carries the sheath with its continuous-transition dilator, puncture needle or cannula, short access wire and syringe — the same composition as the standard radial set, with the coated sheath as the difference. The usual buying decision is not substitution but tiering: standard for the volume, hydrophilic for fine radials, difficult wrists and distal-radial programmes. Both are quoted together in whatever ratio the unit decides.

- 23 cm long sheath as support in tortuous forearms
- Upgrade tier alongside the standard radial set
Frequently Asked Questions — Hydrophilic Introducer Set — 4 to 7 F, up to 23 cm
What is the real difference from the standard radial set?
The sheath: full-length hydrophilic coating that, wet, markedly reduces entry and withdrawal force. Set composition is identical. In practice it shows in fine radials and at withdrawal — the spasm moment — which is why units buy it as a tier for delicate cases rather than replacing all consumption.
What is the 23 cm sheath for?
It reaches past forearm tortuosity: the long sheath straightens the radial-brachial run and gives the catheter a smooth channel to beyond the elbow. It is the answer to looping forearms that turn every catheter advance into a negotiation.
Does the coating need activation?
Yes, with saline before insertion — wet, the surface turns slippery; dry it does not perform. Same principle as this category's hydrophilic guidewire, and the same handling detail worth reminding the unit of at first delivery.
How is it ordered alongside the standard?
In ratio: standard for daily volume, hydrophilic for the delicate fraction — every unit knows its own, usually around 80/20. Both quoted in the same order with each matrix. ISO 13485 documentation and per-batch sterilisation included.

Full Description — Hydrophilic Introducer Set — 4 to 7 F, up to 23 cm
Same set, different sheath
Composition matches the standard radial set; the coated sheath is the difference. Wet, it slides in with markedly less force — and slides out the same way, which is what the spasm moment punishes.
The 23 cm answer
Looping forearms turn every catheter advance into a negotiation. The long sheath straightens the radial-brachial road and hands the catheter a smooth channel past the elbow.
Tier, not substitute
Standard for volume, hydrophilic for the delicate fraction — most units land near 80/20 and order both matrices in one quote.
What to confirm before ordering
- Size × length mix for each tier - Saline activation noted at first delivery — dry it does not perform
