Catheter placement device and method
First Claim
1. A catheter insertion tool for inserting a catheter into a body of a patient, comprising:
- a housing in which a portion of the catheter is initially disposed, the housing including a top housing portion and a bottom housing portion;
a needle distally extending from a distal end of the housing, a portion of the catheter disposed over the needle;
a guidewire initially disposed within the needle;
a guidewire advancement assembly that selectively advances a portion of the guidewire distally past the distal end of the needle;
a catheter advancement assembly extending between the top housing portion and the bottom housing portion for selectively advancing the catheter over the needle and the guidewire after distal extension of the guidewire; and
a support structure for stabilizing the needle distally extending from housing.

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.

8. A catheter insertion tool for inserting a catheter into a body of a patient, comprising:
-
a housing including a top housing portion slidably engaged with a bottom housing portion, the housing having disposed therein at least a hub and a proximal portion of a catheter tube of the catheter; a needle attached to the top housing portion and distally extending from the housing, the needle passing through a lumen of the catheter; a guidewire attached to the bottom housing portion and disposed within the needle, wherein the bottom housing portion is slidable with respect to the top housing portion to enable distal advancement of the guidewire past the distal tip of the needle when the bottom housing portion is selectively moved distally; and a catheter advancement handle operably attached to the catheter and configured to distally advance the catheter over the needle after distal extension of the guidewire so as to insert a portion of the catheter within the body of the patient. - View Dependent Claims (9, 10, 11, 12, 13)
