Apparatus that provides mechanical circulatory support during open-heart surgery, by passing the heart to facilitate surgery on the organ. The basic function of the machine is to oxygenate the body's venous supply of blood and then pump it back into the arterial system. The machine also provides intracardiac suction, filtration, and temperature control. Some of the more important components of these machines include pumps, oxygenators, temperature regulators, and filters. (UMDNS, 1999)

Apparatus and method for mitral valve repair without cardiopulmonary bypass, including transmural techniques
A method and apparatus for repairing the heart's mitral valve by using anatomic restoration without the need to stop the heart, use a heart-lung machine or making incisions on the heart. The method involves inserting a leaflet clamp through the heart's papillary muscle from which the leaflet has been disconnected, clamping the leaflet's free end and then puncturing the leaflet. One end of a suture is then passed through the hollow portion of the clamp, while the other end of the suture is maintained external to the heart. The clamp is then removed and the suture's two ends are fastened together with a securement ring / locking cap assembly to the heart wall exterior, thereby reconnecting the leaflet to the corresponding papillary muscle. The introduction of the clamp, puncturing of the leaflet, passage of the suture therethrough and removal of the clamp can be conducted a plurality of times before each suture's two ends are fastened to the securement ring / locking cap assembly.

Multichannel catheter with obturator
This invention is a multichannel catheter for extracorporeal circulation of blood to a patient undergoing cardiovascular treatments or surgery. The catheter has three independent channels, an obturator and an expandable balloon at one end of the catheter. The first channel is the largest and is of a size that allows for delivery of blood through outlet parts in the wall of the first channel to a patient in an amount sufficient to maintain the patient's metabolism and perfusion throughout the treatment or surgery. The obturator is longitudinally insertable into the first channel. A second channel, smaller than the first, is integrated into the wall of the first channel, and is suitable for delivering a biologically active fluid (e.g., for cardioplegia) to the heart and / or venting the left heart. A third channel, also smaller than the first, is integrated into the wall of the first channel, and suitable for delivering a fluid to the balloon for its expansion when positioned in the ascending aorta to occlude the flow of blood to the heart. The catheter provides an improved means of preparing for or performing cardiovascular surgery on a patient using a cardiopulmonary machine for extracorporeal circulation of blood. The catheter is particularly useful for cardiac surgery.

System and method for heart valve replacement
A prosthetic heart valve replacement system and method aim to reduce the time duration of the patient on the heart-lung machine during surgery. In one embodiment, the invention uses a two rings (e.g., of Titanium) comprising a first outer anchoring ring installed in a first step in the patient annulus, e.g., by stapling (e.g., using Nitinol® staples), and a second inner valve ring which has apertures and to which the sewing cuff of prosthetic heart valve (e.g., of Dacron) is sutured around the sewing cuff. The suturing is expediently completed outside of the patient's body, parallel with the stapling of the anchoring ring in the patient annulus. The inner valve ring may have circumferential resiliency. The inner valve ring along with the fastened / sutured prosthetic valve is installed snugly (in a second step) to be captively retained concentrically within the already installed outer anchoring ring, to complete the heart valve replacement.

The need for a venous reservoir in a heart-lung machine is obviated by using a vacuum-purged negative-pressure air filter in the venous return line ahead of the main blood pump. The purging vacuum for the venous air filter can also be used to purge air from the cardiotomy reservoir if a backflow-preventing valve is used on the venous air filter.
