First Claim
1. A collapsible medical device including:
- first and second conical members, each having a wide end and a narrow end;
a connecting element coupled to the first and second conical members, the connecting element being fixed to the narrow end of each conical member, the first and second conical members being arranged such that their narrow ends are adjacent one another and their wide ends face opposing directions;
the first and second conical members each including a conical membrane having a thickness decreasing from the narrow end to the wide end;
wherein a portion of the conical membrane atthe wide end of each conical member comprises tooth shaped elements with a thickness that enables the tooth shaped elements to be self-supporting, such that the tooth shaped elements retain their shapes without a support or frame elements.

Abstract
A vascular occluder includes first and second conical members disposed in opposing relation and which have tooth-shaped wide ends. The conical members are coupled to one another by a coupling element, which may be a cannula or rod. The conical members are formed of a membrane which has a thickness which increases towards the narrow ends and decreases towards the toothed elements. The toothed elements are preferably self-supporting within a vessel and avoid folds within the occluder membrane, which may otherwise result in leakage of blood around the device. The device may be provided with a supporting frame which may be at least partially embedded within the membrane. The membrane is preferably made of silicone.
