Abstract
Abstract A ventricular cannulation device in which an inner part is placed in the cardiac chamber and an outer part is placed outside the cardiac wall. Each of the inner and outer parts is equipped with means for catching onto the cardiac wall. The inner part bears a means for guiding and attaching the outer part thereto. A tube corresponding to the opening of the cardiac wall serves as a support for an outer tube or a vascular prosthesis.
