Kumpe catheter

The Kumpe catheter, also known as KMP, is a selective access catheter designed for biliary and urinary tract cannulation, in order to secure access, navigate, advance, exchange devices, or deliver contrast in the target destination.

Properties

• proximal end: luer lock hub

• distal tip-shape: angle shaped

• french size: 5F

• length: 40 - 65 cm

• recommend guidewire:

  • 0.038″ (0.97 mm)

• maximum flow injection rate

  • These rates vary according to the manufacturer and should be verified in the catheter package

  • 19 mL/s at 82 bar /1200 psi

Indications

Percutaneous biliary duct access for

• percutaneous cholangiography

• percutaneous biliary drainage¹

• biliary stenting

Percutaneous portal venous access for

• portal vein embolization

Percutaneous renal access for

• percutaneous nephrolithotomy²

• intrarenal infusion therapy (chemotherapy, stone dissolution)

• removal of foreign bodies (encrusted stents)

Endoscopic (cystoscopy) renal access for

• ureteroscopy

Instructions for use

Biliary ducts access

1. flush the catheter

2. after local anesthesia, and ultrasound/fluoroscopic-guided puncture of a biliary duct

3. inject a small amount of contrast to confirm duct puncture on fluoroscopy

4. insert an access wire and dilate the hepatic track with a 5F dilator

5. perform a cholangiogram to confirm the position of the dilator

6. remove the access wire and insert a stiff navigation wire (e.g. Stiff glidewire) and place it into target stenosis / or duodenum

7. exchange the 5F dilator with a 7F short sheath catheter and perform a cholangiogram

8. advance the KMP over the glidewire and into target destination

9. retract the glidewire to allow the formation of the tip catheter

10. once the stenosis is passed / reached target destination, deliver the rail wire through the catheter

11. discard the catheter and mainain the access with the rail wire

Precautions

To prevent biliary/urinary tract injury:

• catheters should be inserted and withdrawn over wires, as the tip of catheters moving can cause injury

• always verify the catheter pressure rate limit while using the power injector

• in case of resistance while advancing or withdrawing the catheter, it is important to stop and identify the underlying cause of the resistance before proceeding further

• avoid bending or kinking the catheter before its placement, as doing so may damage the catheter and lead to injury for the patient
