Access device

A device for inserting a catheter, comprising:

• a base configured to be gripped by a user, said base defining a channel extending along an axis;
• a needle having a distal incising end and a proximal needle hub, the distal incising end having a beveled tip extending along a length LB of said axis;
• a catheter assembly comprising a proximal hub and a catheter that is slidably translatable over the incising end of said needle, thereby defining a trim length LT extending along said axis between a distal end of said catheter and the distal incising end of said needle assembly;
• and
• a catheter advancer that is engaged to said base and configured for translation of said catheter assembly along said axis by a predetermined length LSAFETY prior to threading said catheter into a patient, wherein LSAFETY is greater than or equal to the sum of LB plus LT.
