Abstract
A hole cutter adapted for cutting holes through the sidewalls of medical catheters is fashioned from a hollow tube having a distal cutting end, a proximal ejection end and a lumen of smaller diameter near the cutting end. Slugs formed at the cutting end are extracted by suction applied to the ejection end, and are captured by a filter.
