摘要： A pericardiocentesis apparatus and method for accessing the pericardial space. The invention consists of inserting a percutaneous tube whose tip has a hole which is positioned over and contacts the anterior pericardium. Introducing a vacuum within the tube forms a pericardial bleb within that hole. A guided needle within the tube is advanced to puncture the pericardial bleb while avoiding contact with the epicardium. A hollow filament or electrocardial lead or flexible guide wire within the needle can then be advanced into said pericardial cavity. The guide wire may be used to guide a intrapericardial 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 material(s) can be injected through the needle for the slow and/or sustained delivery of the therapeutic agents into the pericardial cavity.
摘要翻译：一种用于获取心包空间的心包穿刺装置和方法。本发明包括插入经皮管，其尖端具有定位在前心包膜上方并与之接触的孔。在管内引入真空，在该孔内形成心包泡。管内的引导针头前进以刺穿心包泡，同时避免与心外膜接触。然后可以将针内的中空细丝或心电线或柔性导线推入所述心包腔。导丝可以用于将心包内导管引导到心包空间中，用于将选定的治疗剂注射或输注到心包空间中以治疗各种心脏和血管疾病。可以通过针头注射控制的药物释放材料，用于将治疗剂缓慢和/或持续递送到心包腔中。
