Microcatheter combinations investigated and the amount of debris they produced

Step	Side Port	Straight Port	RHV	Amount of Debris
Step	Side Port	Straight Port	RHV	Insertion	Extraction
1 SL-10 Evaluation	None	SL-10	Abbott	–	–
	SL-10	None	Abbott	+	++
	SL-10^{^a}^,^{^b}	Headway 21	Abbott	+	++
	SL-10	Prowler 21	Abbott	+	++
	SL-10 without guidewire	Prowler 21	Abbott	–	–
2 Microcatheter comparison(similar MC to SL-10)	Headway 17^{^a}	Headway 21	Abbott	+	++
2 Microcatheter comparison(similar MC to SL-10)	Echelon 10^{^a}	Headway 21	Abbott	+	++
3 RHV comparison (other RHV)	SL-10^{^b}	Headway 21	Boston Scientific	–	+

Note:—MC indicates microcatheter; – for amount of debris, none; +, identifiable; ++, substantial, "None" under Side Port and Straight Port, absence of device use.
