MECHANICAL DEVICES FOR ARTERIAL OCCLUSION

TLDR

The study presents two mechanical devices designed to occlude vessels. The devices consist of cotton‑tail metallic segments (~2 mm) and wool‑coated steel guidewire segments (~5 cm) that occlude small arteries and major vessels beyond the catheter tip. Their use was investigated in dogs and then successfully applied clinically to occlude renal arteries in patients with hypernephroma.

Abstract

Two mechanical devices for the purpose of occluding vessels are presented. Cotton tails, small metallic segments with attached cotton threads, will effectively occlude small arteries of approximately 2 mm. in diameter. Wool coils, 5 cm. segments of the outer portion of steel guidewires with attached wool strands, obstructed major vessels just beyond the tip of the catheter. The use of these devices has been investigated in dogs and then applied clinically in the occlusion of renal arteries in patients with hypernephroma.
