Abstract: A device and method of use for a partial occlusion device (POD) for matter and liquid flow control. More specifically, a device relating to the partial occlusion of blood vessels to affect the flow of blood through the blood vessels is disclosed. The POD may be formed from a mesh material and includes one or more lumens. The POD may be particularly useful in treating Hypoplastic Left Heart Syndrome, by reducing pulmonary blood flow to decrease the risk of pulmonary hypertension. The POD may also be used to deliver therapeutic agents to a specific site. The POD can be retrieved after placement.

Abstract: A ventricular access device and method. In accordance with the method a grommet is introduced into a ventricle and the grommet conduit is caused to penetrate the ventricle's myocardium in an inside to outside manner. The portion of the grommet conduit external to the ventricle is connected to a primary external conduit. The inventive device is a grommet in the form of a conduit and an extension (e.g. flange) extending outwardly from the conduit. The grommet conduit provides an outlet for the egress of blood from the ventricle. The extension provides contact against the inner wall of the ventricle to hold the grommet in place notwithstanding the outward flow of blood from the ventricle.
