Systems and methods for treatment of perforator veins for venous insufficiency
Systems and methods for the treatment of perforator veins for venous insufficiency are described. The systems can include a catheter assembly comprising a proximal hub, a spin lock on the proximal hub, a elongate body overmolded to the proximal hub, and a distal end, the catheter, the elongate body configured to be placed within a perforator vein; an extension tubing having a proximal female hub, a distal male hub, and an elongate body therebetween, the distal male hub having a spin lock thereon, the distal male hub configured to be attached to the proximal hub of the catheter assembly; a syringe filled with a volume of media including cyanoacrylate; and an injector configured to automatically dispense a bolus of the media sufficient to coapt the perforator vein from the syringe upon actuation of a control on the injector. Methods are also disclosed.
1. A method of treating a vein, the method comprising:
advancing an access needle percutaneously into a perforator vein in a patient under ultrasound guidance;
advancing a portion of a catheter assembly through the access needle and into the perforator vein;
injecting a volume of media comprising cyanoacrylate through the catheter assembly into the perforator vein such that the media substantially does not flow into adjacent superficial or deep veins, the volume of media being sufficient to coapt the perforator vein;
withdrawing the needle and catheter from the perforator vein; and applying external pressure sufficient to coapt the perforator vein.
2. The method of claim 1 , further comprising confirming coaptation of the perforator vein under ultrasound guidance.
3. The method of claim 1 , wherein the catheter assembly is operably connected at a proximal end to an extension tubing, wherein the extension tubing is operably connected at a proximal end to a media-filled syringe.
4. The method of claim 3 , wherein the media-filled syringe is operably connected to an injector configured to automatically dispense a bolus of about 0.05 cubic centimeters (cc) of the media from the syringe upon actuation of a control on the injector.
5. The method of claim 1 , wherein the volume of media is between about 0.01 cubic centimeters (cc) and about 0.10 cc.
6. The method of claim 1 , wherein the volume of media is about 0.05 cubic centimeters (cc).
7. The method of claim 1 , wherein the catheter assembly is operably connected at a proximal end to an extension tubing, the method further comprising priming the extension tubing and catheter assembly with the media prior to the injecting step.
