Abstract
A plurality of resilient wires interconnected at their respective ends form a collapsible filter basket adapted to be introduced into a blood vessel of a patient. The basket in its expanded and relaxed state forms an apertured, elongate solid of revolution with pointed ends and has a base as measured between the pointed ends at least equal to the maximum diameter thereof. The design of the filter basket of the present invention facilitates insertion and adjustment of position or orientation once inserted and allows large masses of emboli to build up without seriously restricting the free area available for blood flow through the filter.
