Fibrin Sheath Disruption Case Study

Chameleon™ PTA balloon catheter

Explore the ways physicians use the Chameleon™ PTA balloon catheter for paired fibrin sheath diagnosis, angioplasty, and results verification with one device.

Addressing fibrin sheath with the Chameleon PTA balloon catheter

Visualize dialysis catheter dysfunction

Removing fibrin sheath is important to prevent the recurrence of catheter flow dysfunction in a new catheter. The Chameleon™ PTA balloon catheter visualizes the fibrin sheath during and after the angioplasty procedure by injecting contrast media through the catheter without using a sheath.

Case review of fibrin sheath from diagnosis-to-confirmed elmination

Ari Kramer, M.D., reviews case steps in simultaneous imaging and angioplasty for fibrin sheath disruption using the Chameleon™ PTA balloon catheter with integrated injection port.

Fibrin sheath case review with Jeffrey Hoggard, M.D.

  • AV graft with venous anastomotic stenosis
  • Sheathless, maintaining wire access
  • Use of 8×40 mm Chameleon™ PTA balloon catheter
  • Immediate verification of procedure status

Fibrin sheath disruption procedural approach

Step-by-step PTA technique review

1. Identification and diagnosis of fibrin sheath

  • Guidewire is inserted through a catheter lumen
  • The tunnel cuff is freed
  • The tip of the catheter is pulled back into the proximal brachiocephalic vein over the wire under fluoroscopic guidance
  • Contrast is injected through the other (open) lumen

2. Angioplasty performed using the Chameleon PTA balloon catheter

  • Old catheter is removed over the wire
  • Chameleon™ PTA balloon catheter is inserted over the same wire and positioned inside the fibrin sheath
  • Serial tangential angioplasty disrupts the length of the fibrin sheath

3. Immediate post-angioplasty imaging using the integrated third port to confirm proper disruption

  • The Chameleon™ PTA balloon catheter diagnostic port is positioned in the proximal brachiocephalic vein
  • Contrast is injected via the integrated diagnostic port, providing post-angioplasty imaging
  • Proper fibrin sheath disruption/removal is confirmed via contrast imaging
