摘要:
Disclosed is an occlusion device for use in a body lumen such as the left atrial appendage. The occlusion device includes a pumpable injectable material and a retention member having a tissue penetrating shaft which extends from a proximal end of the device to a distal end of the device.

An implantable device for containing emboli within an atrial appendage may include an expandable frame having a plurality of supports projecting distally from a proximal hub, a mesh barrier provided on proximal sections of the supports, and a plurality of tissue anchors provided on the supports for engaging tissue when the device is positioned in an atrial appendage.

Disclosed is an occlusion device for use in a body lumen such as the left atrial appendage. The occlusion device includes an occlusion member and may also include a stabilizing member. The stabilizing member inhibits compression of the left atrial appendage, facilitating tissue in-growth onto the occlusion member. Methods are also disclosed.

摘要:
A device and method for obliterating or occluding a body cavity or passageway, in particular, the left atrial appendage of a patient's heart. The procedure can be carried out intraoperatively, but is preferably carried out percutaneously by use of a delivery catheter to position an occluding device adjacent a patient's left atrial appendage. The occluding device may prevent the passage of embolic or other material to or from the left atrial appendage by volumetrically filling the appendage, closing the opening of the appendage with an occluding member, or pulling the tissue around the opening of the appendage together and fixing it in a closed state.

摘要:
Clot disruption and dissolution are achieved using a catheter having the ability to infuse a thrombolytic agent, aspirate clot and fluid, and allow passage of a guidewire. Optionally, the catheter may also include a mechanical agitator for further disrupt clot in the presence of the thrombolytic agent. A flow resistor in the catheter provides for infusion and/or aspiration to be concentrated primarily at a clot treatment area in a blood vessel while also providing optional infusion and/or aspiration distal to the treatment area. In some embodiments, infusion, aspiration and guidewire passage occur through a common lumen. The thrombolytic agent, such as tPA, streptokinase, or urokinase, is directly released into the clot at the point where the agitator is engaging the clot. In this way, the thrombolytic activity of the agent is enhanced and the dissolution of the clot is improved.

Methods, systems, and devices seal off the branch port of a bifurcated endoluminal prosthesis to transform the bifurcated prosthesis to a single-lumen prosthesis. These methods and devices are available for fallback procedures when the deployment of a bifurcated endoluminal prosthesis is found to be impracticable. By effectively sealing off the second branch port, the attending physician is able to completely isolate an aneurysm or other disease of the vasculature. Where it is necessary and/or desirable to provide fluid communication between the trunk lumen and the second branch lumen, a separate passage may be provided between the first and second branches of the body lumen system.
