First Claim
1. An insertion tool for inserting a catheter into a body of a patient, comprising:
- a housing;
a needle distally extending from the housing, the catheter pre-disposed over the needle;
a guidewire having a distal end pre-disposed in a lumen of the needle;
a guidewire advancement assembly designed to distally advance the distal end of the guidewire out of a distal opening of the needle; and
a catheter advancement assembly designed to distally advance the catheter, the catheter advancement assembly including a proximal portion in locking engagement with the housing when the guidewire advancement assembly is in a guidewire retracted position, the guidewire advancement assembly including an actuation member designed to disengage the proximal portion in a guidewire advanced position,the catheter including;
a catheter hub pre-disposed in the housing;
a catheter tube extending from the catheter hub, the catheter tube including a first material from a proximal end to a distal tip; and
a reinforcement component included in the distal tip of the catheter tube, the reinforcement component including a second material more rigid than the first material.

Abstract
An insertion tool for inserting a catheter into a patient'"'"'s body is disclosed. The insertion tool unifies needle insertion, guidewire advancement, and catheter insertion in a single device. In one embodiment, the insertion tool comprises a housing in which at least a portion of the catheter is initially disposed, a hollow needle distally extending from the housing with at least a portion of the catheter pre-disposed over the needle, and a guidewire pre-disposed within the needle. A guidewire advancement assembly is also included for selectively advancing the guidewire distally past a distal end of the needle in preparation for distal advancement of the catheter. In one embodiment a catheter advancement assembly is also included for selectively advancing the catheter into the patient. Each advancement assembly can include a slide or other actuator that enables a user to selectively advance the desired component. Guidewire and catheter locking systems are also disclosed.
