Can anyone tell me the benefit if any of inserting the microintroducer in a corkscrew fashion compared to one fluid push? Is it less traumatic? Thank You
I am familiar with this technique as clinicians who use the Arrow sheath may use a back-and-forth twisting motion to inset it thru the skin and into the vessel. The transition from the dilator to the sheath is so smooth and precise that one does not routinely need a skin nick. The "pop" that is generally felt when the sheath enters the vessel is also eliminated due to this transition, thus decreasing trauma to the vein wall. The device is "thin-walled" and is cupped within the hand while inserting. There are times when twisting is not needed as the device can simply be pushed in.
FYI, I used this sheath for 8 years before joining Arrow as a clinical specialist so my experience is first-hand.
