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.

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: In one embodiment, the present invention provides a cardiac lead device including a fixation mechanism slidably attached to the lead such that when the fixation mechanism is expanded in to contact with a body lumen, the lead may be moved relative to the fixation mechanism if desired. Such lead movement may be limited by complimentary structure on the lead body and the fixation mechanism that prevents the lead from moving unless sufficient force is applied to the lead.

摘要: The present invention is a medical assembly comprising an elongated flexible medical device, such as a cardiac lead, and a torquing member, such as a stylet, slidably receivable inside the medical device. The device and member are coupled at their distal ends by a corresponding set of opposing curves. This coupling allows more precise rotational control of the assembly when it is manipulated at its proximal end. In one embodiment, the assembly has a open curvature at its distal end. In another embodiment, the distal end has a closed curvature.

摘要: An improved guidewire for assisting in implantation of a cardiac lead includes three sections. The most distal zone is sufficiently floppy to prevent trauma to the vessel walls through which the guidewire and lead are inserted. An intermediate zone is generally stiffer and has a cross-section less than or equal to the cross-section of the distal zone. The third zone is stiffer yet and is joined to the intermediate zone by a shoulder. The shoulder cooperates with protrusions on the lead to transfer forces between the guidewire and lead. A removal wire having temporary locking device to lock the removal wire to the lead is employed to remove the guide catheter without moving the lead from its desired location. Lubricious coatings are also provided to reduce friction between the lead and guidewire.
