摘要： A device and method for accessing a pericardial space of the heart includes a shaft having a cavity at a distal end, a suction lumen terminating in a distal port within the cavity and a hollow needle having a distal tip extending into the cavity. The cavity may be a recess in the shaft into which the distal tip of the needle fixedly protrudes. In other embodiments, the cavity is formed by an inflatable member positioned at the distal end of the shaft and the needle is slidable relative to the shaft. Suction is applied at the cavity to draw a pericardial bleb. The needle pierces the pericardial bleb for accessing the pericardial space and also facilitates delivery of payloads into the pericardial space.

摘要： A breakaway hemostasis hub for a catheter or introducer sheath includes a splittable or separable housing, a seal within the housing, an actuator partially slidably disposed within the housing, a pair of spring retainer members in the housing each adapted to receive at least one spring, and a pair of actuator retainer members adapted to retain the seal, the actuator, and the spring retainer members in the housing. The actuator is operable to assume a closed position and an open position and includes a dilator member configured to dilate the seal when the actuator is in the open position. The hub is splittable or separable into two generally symmetrical sub-assemblies to facilitate cutting the catheter for retraction from the patient's body without displacing its payload.

摘要： The present invention provides a cardiac vascular occlusion system which includes inner and outer guide catheters and an occluding member disposed on the inner catheter. The occluding member may be deployed from a compressed to an expanded position to limit retrograde blood flow in a body lumen. The occluding member may be used when injecting a contrast agent into the body lumen.
