    摘要： A fluid collection container (100) includes a vessel (101) and a lid (102). A mesh conduit layer (201) is coupled to the vessel so as to span an opening (110) of the vessel and enclose an interior (111) of the vessel. The mesh conduit layer is liquid permeable and serves as a splash retarding mechanism that prevents liquids being transferred through the mesh conduit layer from splashing back. An optional cache (603) of coagulant material can be disposed within an interior of the vessel as well.

    摘要： A switch for selectively directing fluid to either one of two catheters and for inflating a "manually" inflatable balloon of one of the catheters when fluid is directed to that catheter. The switch includes a valve mechanism that is operatively linked with a balloon inflation mechanism such that the balloon is inflated when fluid is directed to that catheter, and the balloon is deflated when fluid is directed to the other catheter. The switch is particularly adapted for use in administering cardioplegia solution to a patient's heart alternatively via an antegrade cardioplegia catheter and a retrograde cardioplegia catheter. A method of use of the switch is also disclosed.

    摘要： A coronary sinus catheter for the retrograde infusion of cardioplegia solutions into the coronary sinus. The catheter is adapted for improved retention in the coronary sinus. The catheter comprises a catheter tube having infusion, pressure-sensing and balloon-inflation lumens, an inflatable balloon and a pressure sensor tube in fluid communication with the balloon-inflation lumen for sensing pressure in the inflatable balloon. The internal volume of the pressure sensor tube is relatively non-expansible relative to the internal volume of the inflation balloon in normal operation of the catheter. Other aspects of the invention include a constricted portion in the infusion lumen that is believed to eliminate spraying of fluid through the infusion lumen outlet(s), and a temperature sensor strip providing a display on the catheter of the temperature of the infused fluid.

    摘要： A low velocity aortic cannula having a proximal end, a distal end, and a lumen therebetween for conducting blood, the distal end being adapted for insertion into the aorta during heart surgery to provide blood to the aorta. There is a diffuser at least partially blocking the distal end of the cannula, and a plurality of outlet openings in the side of the distal end of the cannula. In one embodiment the distal end of the cannula is closed with a cap, and the diffuser is a rounded cone extending generally upstream in the lumen. The outlet openings are located in the sidewall of the cannula. In a second embodiment of the invention, the diffuser has a helical configuration, and partially blocks the distal opening of the cannula. Additional openings are provided in the sidewall to permit flow. According to the method of this invention, an opening is formed in the aorta, the distal end of one of the embodiments of the cannula is inserted into the opening, and blood flow through the cannula is established.

    摘要： An improved aortic cannula having a sidewall with a proximal end, a distal end, and a lumen therebetween for conducting blood, the distal end being adapted for insertion into the aorta during heart surgery to provide blood to the aorta. The cannula has a cap substantially blocking axial flow through the distal end of the lumen. There are a plurality of outlet openings in the sidewall of the cannula adjacent the distal end. The distal end of the lumen is flush with or preferably distally beyond the distal ends of the outlet openings. The aortic cannula may have a bend therein, as is known in the art, in which case the outlet openings on the outside side of the bend are smaller than the outlet openings on the inside side of the bend, to reduce disparity in the flow that would otherwise be caused by the bend, substantially equalizing flow through the openings. According to the method of this invention, an opening is made in the aorta of the patient; the distal end of the cannula is inserted into the opening in the aorta; and blood flow through the cannula is initiated to provide blood to the aorta without jetting.
