Abstract
A method can include engaging the pericardium of a patient at two engagement positions of the pericardium. The method can further include moving the two engagement positions of the pericardium away from each other to tension a portion of the pericardium. The method can further include advancing an access device through the tensioned portion of the pericardium to introduce the access device into the pericardial space of the patient. Other and further methods are also disclosed.
Claims20
A method comprising:
- engaging the pericardium of a patient with first and second arms of a tissue engagement device, wherein the first and second arms cross each other at a position that is distal to an actuation member of the tissue engagement device during said engaging;
- tensioning a portion of the pericardium by advancing the actuation member relative to the first and second arms distally beyond the position at which the first and second arms crossed each other during said engaging, thereby uncrossing the first and second arms, while the first and second arms continue to engage the pericardium;
- and
- after said tensioning, advancing an access device through the actuation member and through the tensioned portion of the pericardium to introduce the access device into the pericardial space of the patient.

A method comprising:
- engaging the pericardium of a patient with first and second arms at two engagement positions of the pericardium, wherein the first and second arms cover a distal opening of an actuation member during said engaging;
- moving the two engagement positions of the pericardium away from each other to tension a portion of the pericardium by moving the first and second arms via the actuation member, thereby uncovering the distal opening of the actuation member, while the first and second arms continue to engage the pericardium;
- and
- advancing an access device through the distal opening of the actuation member and through the tensioned portion of the pericardium to introduce the access device into the pericardial space of the patient.
