US 10,869,655 B2 · Systems and methods for treatment of perforator veins for venous insufficiency

Abstract

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.

Dependent claims

A method comprising:

advancing an access needle percutaneously into a perforator vein in a patient;
advancing a portion of a catheter assembly through the access needle and into the perforator vein;
injecting a volume of media comprising a vein-occluding substance 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 access needle and the catheter assembly from the perforator vein;
and
applying external pressure sufficient to coapt the perforator vein.

A 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;
applying pressure to a portion of the patient to occlude a portion of the perforator vein;
subsequent to applying pressure to the portion of the patient, injecting a volume of media comprising an adhesive 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 and from approximately 0.01 cubic centimeters (cc) to approximately 0.10 cc;
withdrawing the access needle and the catheter assembly from the perforator vein;
applying external pressure to the patient sufficient to coapt the perforator vein with the volume of media injected into the perforator vein;
and
confirming coaptation of the perforator vein under ultrasound guidance.
