Catheter placement device and method
First Claim
1. An insertion tool for inserting a catheter into a body of a patient, comprising:
- a housing;
a needle having a proximal portion in the housing and a distal portion extending from a distal end of the housing;
a catheter advancement assembly, comprising;
the catheter coaxially disposed over the needle, the catheter having a proximal end in the housing and a distal end extending from the distal end of the housing in a catheter first position; and
a handle coupled to the proximal end of the catheter, the handle extending laterally from the housing in the catheter first position, the handle slidable with respect to the housing to transition the catheter distally from the catheter first position to a catheter second position; and
a guidewire advancement assembly, comprising;
a guidewire disposed at least partially in a lumen of the needle; and
a slide member coupled to the guidewire, the slide member slidable with respect to the housing to transition the guidewire relative to the needle.

Abstract
An insertion tool for inserting a catheter into a body of a patient 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.
