Abstract
An introducing apparatus includes an elongate tubular sheath having an external diameter small enough to be readily insertable in a selected vein. The sheath has a bore which receives therein a dilator such that a distal end of the dilator projects from out from the distal end of the sheath. A rotatable fastener is rotatably coupled with the dilator, and couples the sheath with the dilator and prevents axial movement therebetween. An anti-rotation member is associated with the dilator and/or the sheath, which prevents the dilator from rotating relative to the sheath as the rotatable fastener is rotated, and also included are means which allow a user to overcome the anti-rotation features without damage to or inadvertent separation the sheath.
