Embodiment Construction

[0025] Devices and methods for accessing the pericardial space through the pericardium are described herein. The pericardium is the tough membrane that surrounds the heart. figure 1 Heart 100 surrounded by pericardium 102 is depicted. figure 1 Various anatomical structures of the heart are also depicted, including the left atrium 106, left atrial appendage 108, left ventricle 110, and aortic arch 103. The pericardium 102 may be filled with fluid, which may separate it from the heart. The space between the pericardium 102 and the heart 100 is the pericardial cavity 104 . The distance between the pericardium and the surface of the heart can vary. For example, the pericardium may be approximately 5 millimeters from the heart in some regions, while the pericardium may directly contact the heart 100 in other regions. Although the devices and methods described herein relate to piercing the pericardium to provide access to the heart, it should be understood that these devices and...

Abstract

Described here are devices, systems, and methods for accessing the pericardial space through the pericardium. The access devices may include a plurality of elongate members having lumens that may be advanced together through the body to the pericardium. The elongate members may have different lengths and may be slideably positioned one within the lumen of another. At least one of the elongate members may comprise a distal tip configured to pierce tissue. In some instances, the access devices may also comprise a locking member to constrain the position of one elongate member relative to another.

Description

technical field [0001] Devices and methods for gaining access to the pericardial space through the pericardium are described herein. Background technique [0002] It may be desirable to gain access to the internal and external structures of the heart in order to treat cardiovascular disease. In some cases, treatment may involve delivery of one or more devices to the heart. The heart can be accessed in a variety of ways. For example, intravascular approaches may be used to access the heart for device delivery. In such an approach, the device can be advanced from the femoral vein to the vena cava, through which the ventricles and valves on the right side of the heart can be accessed (eg, right atrium, right ventricle, etc.). An endovascular approach can also be used to access the left side of the heart through the transseptal puncture. Alternatively, the left atrium and left ventricle can be accessed endovascularly from the aorta via a retrograde route. [0003] Endovascu...
