Beschreibung
Zusammenfassung:	This invention is a pericardial centesis apparatus (100) and method for accessing the pericardial space. The invention consists of inserting a percutaneous tube (104) whose tip has a hole (123) which is positioned over and contacts the anterior pericardium. Introducing a vacuum within said tube (104) forms a pericardial bleb within that hole. A guided needle (124) within the tube is advanced to puncture the pericardial bleb while avoiding contact with the epicardium. A hollow filament or electro-cardial lead or flexible guide wire (114) within said needle can then be advanced into said pericardial cavity. The guide wire (114) may be used to guide an intra-pericardial catheter into the pericardial space for injection or infusion of selected therapeutic agents into the pericardial space to treat various heart and blood vessel diseases. Controlled drug release materials can be injected through said needle (124) for the slow and/or sustained delivery of said therapeutic agents into said pericardial cavity.
