1. A device for self-centering a medical instrument in a conduit within a patient, said device comprising:
a flared body defining a central lumen, said flared body having a proximal end with a proximal diameter, a flared distal end with a distal diameter greater than the proximal diameter, and an interior side surface extending between said proximal end and said distal end and blocking fluid flow therethrough;
wherein two or more apertures are defined in said flared body to provide open fluid flow paths through which fluid can pass through said flared body.
