Abstract
Systems, kits, and methods that provide direct visualization of a patient's surgical field and intracardiac structures during implantation of a mechanical circulatory support device. Kits and methods can provide for seamless implantation of such devices, which reduces the risks and time associated with mechanical circulatory support device implantation. Further, methods are provided that can avoid cardiopulmonary bypass.
Claims16
A cardiac chamber visualization kit comprising:
- an occlusion system comprising:
- a catheter having a distal portion and a proximal portion and at least one lumen extending therein;
- a distal occluder mounted on the distal portion of the catheter;
- and
- a proximal occluder mounted on the proximal portion of the catheter;
- and
- a mechanical circulatory support device.
The cardiac chamber visualization kit of 2, wherein the distal expandable member is a distal balloon and the proximal expandable member is a proximal balloon.
A method of visualizing a cardiac chamber for insertion or removal of a mechanical circulatory support device in a patient comprising:
- providing an occlusion system comprising:
- a catheter having a distal portion and a proximal portion and at least one lumen extending therein;
- a distal occluder mounted on the distal portion of the catheter;
- and
- a proximal occluder mounted on the proximal portion of the catheter;
- introducing a cannula into a cardiac chamber of the patient through a cardiac chamber wall;
- inserting the occlusion system into the cannula with the distal and proximal occluders in a contracted state;
- introducing the distal and proximal occluders into the cardiac chamber;
- expanding the distal and proximal occluders sequentially or simultaneously into an operative configuration;
- coring tissue of the cardiac chamber wall;
- removing the cored tissue of the cardiac chamber wall;
- de-airing the cardiac chamber;
- removing the distal and proximal occluders from the cardiac chamber;
- connecting a mechanical circulatory support device to the cored cardiac chamber wall via an inflow cannula.
