Abstract

An apparatus for passing a guidewire through a subcutaneous tissue tunnel to enable over-the wire insertion of a catheter through the tissue tunnel. The apparatus comprises an elongated member having a distal end portion having a tip configured to advance through the tissue tunnel and an opening extending longitudinally with respect to the apparatus and dimensioned to receive the guidewire. The guidewire is inserted through the opening to pass the guidewire through the tunnel to enable subsequent insertion of the catheter.

Claims (14)

1. A method for over the wire placement of a catheter through a tissue tunnel and into a vessel comprising;

inserting a guidewire into the vessel so a proximal portion extends proximally of a patient's body;

providing a guidewire retrieval member;

passing the guidewire through the tissue tunnel via the guidewire retrieval member so a proximal end of the guidewire extends through a proximal opening of the tissue tunnel and outside the patient's body; and

advancing a catheter over the guidewire through the subcutaneous tissue tunnel and into the patient's vessel.

2. The method of claim 1 , further comprising the step of advancing the guidewire retrieval member distally through the subcutaneous tissue tunnel prior to passing the guidewire through the tissue tunnel.

3. The method of claim 1 , further comprising the step of threading the guidewire through a longitudinal opening in the retrieval member.

4. A method for determining a length of catheter for insertion over a guidewire extending through a tissue tunnel and into a vessel comprising;

inserting the guidewire into the vessel so a proximal portion extends proximally of a patient's body;

passing the guidewire through the tissue tunnel so a proximal end of the guidewire extends through a proximal opening of the tissue tunnel and outside the patient's body; and

advancing a device over the guidewire through the subcutaneous tissue tunnel and into the patient's vessel to determine a length of catheter.

5. The method of claim 4 , wherein the device contains markings and the step of advancing the device to determine the length of the catheter includes viewing the markings to provide an indicator of the length of the catheter.

6. The method of claim 5 , wherein the device comprises a dilator and the step of advancing the device includes advancing the dilator to dilate tissue.

7. The method of claim 4 , wherein the device comprises a stiffener rod and the step of advancing the device includes advancing the stiffener rod.
