• Allows easy catheterization of mice
• Permits attachment to a standard 25 gauge or 22 gauge swivel
• Two sizes available:
– 1.2 French to 2 French for use with 25 gauge swivels
– 1.2 French to 3 French for use with 22 gauge swivels
• Extruded tube provides a seamless connection for no leaking!
The increase in catheterization of mice has brought to light a vexing problem: how to attach a tiny catheter to conventional devices such as swivels and luer stubs. The solution is the innovative Funnel-Cath™.
Funnel-Cath™ is extruded from the same implant-grade polyurethane used in our SoloCaths, see page B33, though a bit stiffer to facilitate placement in mice. We offer two sizes: (1) a 2Fr proximal end for attachment to a 25ga swivel, tapering down to a 1.2Fr intravascular segment, and (2) a 3Fr proximal end for attachment to a 22ga swivel, also tapering down to 1.2Fr.
Before the Funnel-Cath™ there were two ways of tapering a catheter. The first involved “pulling down”, or stretching, tubing using an open flame or hot oil. This method was cumbersome and the catheters were inconsistent. The second method involved bonding a smaller catheter to a larger one. Catheters produced this way were typically vulnerable to breakage and leaks. The new Funnel-Cath™ is the first and only catheter tapered during the extrusion process, making it seamless and consistent catheter to catheter, batch
to batch.
These Catheters are uncoated polyurethane with a clear, rounded distal tip, two movable suture bulbs, and an attachment sleeve.
They are supplied individually.
