摘要：
Apparatus and methods are provided for accessing a region within a patient's body and performing a procedure therein that includes a catheter including a tubular member comprising a proximal end, a distal end sized for introduction into a patient's body, an imaging assembly on the distal end, and a substantially transparent expandable member attached to the tubular member distal end such the imaging assembly is disposed within an interior of the expandable member, the imaging assembly imaging through a surface of the expandable member. The tubular member includes a drainage lumen communicating one or more drainage ports on the tubular member distal end proximal to the balloon for aspirating fluid from the patient's body. The catheter may be used to access a pericardial space and an ablation probe may be introduced through the catheter to treat heart tissue while fluid is infused and/or aspirated via the drainage ports.
