Claim:
1. An assembly for catheterism, comprising: a guide for catheterism, having a proximal end and a distal end, and defining a longitudinal axis, wherein the distal end of the guide is flexible; an appendage or endpiece attached to the distal end of the guide, the appendage or endpiece having a shape which is axisymmetric about the longitudinal axis, wherein the appendage or endpiece comprises a channel extending along the longitudinal axis; and a catheter comprising an axial lumen configured for slidingly receiving the guide, wherein the axial lumen has a diameter smaller than a maximum diameter of the appendage or endpiece; wherein the distal end of the guide comprises a portion having a continuous diameter, the portion extending along the longitudinal axis; wherein the portion having a continuous diameter comprises a distal part adjacent the appendage or endpiece and a proximal part extending from the distal part towards the proximal end of the guide, wherein the channel receives the distal part of the portion having a continuous diameter, wherein the proximal part of the portion having a continuous diameter extends outwardly beyond the channel and the axial lumen receives the proximal part of the portion having a continuous diameter; wherein a proximal surface of the appendage or endpiece around the channel engages a distal face of the catheter and blocks movement of the catheter relative to the appendage or endpiece; wherein the appendage or endpiece is configured for detaching from the guide within a human or animal body by exerting a force oriented in a distal direction between the catheter and the appendage or endpiece to disengage the appendage or endpiece from the distal end of the guide, wherein the flexible distal end of the guide provides for continued atraumatic navigation through the human or animal body when the appendage or endpiece is removed.
