Wire guide and technique for Cantor tube insertion. Rapid small bowel intubation.

A rapid method of small bowel intubation using a specially designed teflon coated 12 foot wire guide and a Cantor tube is described. The method permits rapid decompression of the small bowel. A further application of the technique for immediate small bowel opacification for localization of obstructing lesions is also suggested.

Needle Holder and Guide for Pulmonary Aspiration Biopsy

Abstract A newly-designed radiopaque plastic needle holder and guide for use in pulmonary aspiration biopsies is described. Utilization of this instrument permits accurate guidance of the needle tip directly to small lesions, under fluoroscopic control, without excessive radiation to the operators hands.

Catheter Tip Deflector System for Selective Bronchography

Percutaneous transcricothyroid membrane catheterization of the bronchial tree for bronchographic examination is simple and safe (5). For entrance into small subsegmental branches, catheters of various curvatures are required. It is often necessary to exchange various preshaped catheters when studying several subsegmental branches, thus prolonging the procedure and increasing the possibility of complications. The use of a catheter tip deflector system obviates the need for such substitution. Following the introduction of guides for angiography (4, 6), application of these technics for controlling catheters in bronchography was suggested (7). The use of a catheter tip deflector system2 is ideally suited for regulating and varying the curvature of any catheter following its percutaneous introduction through the cricothyroid membrane. The system consists of a tip-deflector handle and a short (35 cm) Teflon-coated wire (O.D. 1.14 mm). The tip-deflecting guide wire allows controlled curvature from 0 to 180° and...
