Method and apparatus for delivering a lead to a heart |
摘要 |
A method and apparatus for creating and accessing an anatomic space between a heart and a pericardial sac. The apparatus includes a catheter having a cryoadhesion member situated on the distal tip of the catheter. The cryoadhesion member is utilized to adhere to the pericardial sac and to retract the sac to create a tent like structure. The catheter allows introduction of an instrument to access the pericardial sac by puncture. The access to the pericardial sac allows delivery of a device, a drug, a biologic or other substance to the heart or the space around the heart.
