Patel Set
®
contains:
Flexcore ® Biopsy Needle, 18 ga or 19 ga, 65 cm overall length, 16.5 mm notch, 20 mm throw (Figure 1)
7 fr Introducer with Protective Sheath and Valve Assembly with Safety Guide, 60 cm overall length (Figure 2)
Tissue Removal Swabs, 10 cm length, polyurethane foam tip, nylon handle (Figure 3)
For convenience, some Sets contain additional optional components that may be used based on clinician
preference and discretion:
5 fr Curved Catheter, 76 cm overall length, for delivering a guidewire to the Right Hepatic Vein (Figure 4) (Not Available
in All Markets)
5 fr Straight Catheter, 65 cm overall length for smoother transition between the 7 fr Introducer and guide wire (Figure 5)
SUGGESTED PROCEDURE
1. Prepare the patient for transjugular access per clinical protocols.
2. Charge the Needle (Figure 1) by pulling back on the Plunger (A) (Figure 6 and 7) until a firm click is felt and heard
and gently place it for later use.
3. Obtain venous access.
4. Introduce and seat a guidewire into the right hepatic vein using a wire introducing means, such as the 5f Curved
Catheter (Figure 3) (provided in some sets) or by other methods.
5. Remove the wire introducing means.
Caution: The 5 fr Curved Catheter (Figure 4) is not designed to be re-formed, straightened or used through the 7 fr
Introducer (Figure 8). Doing so can lead to tip failure or detachment.
6. Optional: Insert the 5 fr Straight Catheter (Figure 5) (provided in some sets) coaxially within the 7 fr Introducer.
Caution: Use of a catheter that is not supplied in the kit could lead to incompatibility, delays or complications.
Caution: The 7 fr Introducer (Figure 2) is stiffened, and flexing or other manipulation of the tip of the 5 fr Straight
Catheter (Figure 5) while inserted inside the 7 fr Introducer or other extreme handling can lead to tip failure or
detachment.
Note: Temporarily disconnecting the Valve Assembly (E) on the 7fr Introducer (Figure 2) may facilitate loading the 5
fr Straight Catheter (Figure 5) into the 7 fr Introducer. The Valve Assembly may be disconnected by grasping the two
transparent portions (G) on the Valve Assembly (E) and rotating one portion versus the other.
