Abstract: A perfusion catheter for use in open heart surgery having an inflatable cuff adjacent the distal end in communication with the lumen of the catheter to self-inflate when perfusion liquid is introduced into the lumen. A plug in the lumen within the cuff causes lumen flow to by-pass from the proximal end of the cuff to the distal end of the cuff through transverse parts in the lumen. A flow restriction at the distal end of the lumen causes pressure build-up to inflate the cuff. A pressure monitoring lumen splices to the catheter tube to parallel the tube down to the distal end where it is in communication with the end of the catheter and also with the distal end of the cuff to register cuff pressure. An introducer shaft is provided to be inserted into the lumen to abut the plug to stiffen the catheter, thus facilitating insertion, and a stiffener spine at the cuff area of the catheter also provides rigidity to compensate for the weakening of the lumen resulting from the transverse ports. A cross-port between the pressure monitoring lumen and the main lumen distally of the cuff will register lumen pressure if both the main lumen and the monitoring lumen become occluded at the distal end of the catheter.

Abstract: A needle hub for use with a syringe in obtaining biopsy specimens. A needle is inserted into the area from which a specimen is to be taken. A vacuum is pulled on the needle lumen to cause tissue to be drawn into the lumen. A special vacuum release is provided on the needle hub so that a surgeon can roll back an O-ring in the hub to expose the interior of the hub to atmosphere, thus releasing the vacuum pull on the needle lumen and allowing the needle to be withdrawn without dilution of the specimen, or contamination by material from other sites.

Abstract: A prepackaged, self-contained fluid circuit module is selectively movable by an operator into and out of operative association with one or more pump rotors. The module includes a housing which supports two or more flexible conduits, which together define a prearranged fluid circuit. Portions of the flexible fluid conduits are outwardly disposed from the housing in upright, freestanding positions, even when the module is out of operative association with the pump rotors. The upright portions are purposely arranged relative to each other to facilitate only a particular operative relationship between the fluid circuit and the pump rotors when the module is subsequently moved into operative association therewith.

Abstract: An apparatus and system for administering cardioplegic solution to a heart during open heart surgery. A source of solution is delivered to a control switch from a single tube source and the tube is divided at a "Y" connector into two tubes, one for antegrade delivery and one for retrograde delivery. The control switch has a prime position with both divided tubes open. Movement from prime position to an operative position is irreversible. In the operative position, there is an "off" position with both tubes closed, an antegrade position with the antegrade tube open and the retrograde tube closed, and a retrograde position with the retrograde tube open and the antegrade tube closed. Movement from one position to the other requires movement through the "off" position so there can be no cross-flow from antegrade to retrograde. Pressure monitoring tubes are incorporated into the switch to be opened and closed with the respective tubes.
Abstract translation: 一种用于在心脏开放心脏手术期间向心脏施用心脏停搏液的装置和系统。 解决方案的来源从单个管源传送到控制开关，并将管分为“Y”连接器，分成两个管，一个用于顺行输送，一个用于逆行输送。 控制开关具有两个分开的管子的主要位置。 从主要位置到操作位置的运动是不可逆转的。 在操作位置，有两个管子关闭的“关闭”位置，顺行位置与顺行管打开，逆行管闭合，逆行位置与逆行管打开并且顺行管闭合。 从一个位置到另一个位置的运动需要通过“关闭”位置移动，从而不会从顺行的逆流逆向流动。 压力监测管被并入开关中以与相应的管打开和关闭。

Abstract: The blood processing method, and the apparatus for performing the steps of the method are utilized in separating whole blood into its components and include the steps of, or component parts of the apparatus for carrying out these steps of: pumping whole blood from a donor; passing the whole blood through a first chamber in a centrifuge device: centrifuging the whole blood in the centrifuge device to cause sedimentation of red blood cells from the whole blood in, and separation of platelet rich plasma from the whole blood in, the first chamber; pumping the separated platelet rich plasma from the first chamber and out of the centrifuge device where it is monitored and then back into the centrifuge device and through a second chamber in the centrifuge device where the platelet rich plasma is centrifuged to cause sedimentation of the platelets therein while passing the remaining blood fluid though the first chamber and back to the donor; recombining the plasma passed through the second chamber with the blood fluid passed through the first chamber for return to the donor; monitoring the platelet rich plasma outisde of the centrifuge device and sensing the presence of red blood cells in the platelet rich plasma; stopping and then reversing movement of the platelet rich plasma mixed with red blood cells when a mixture is sensed to return the mixture of platelet rich plasma mixed with red blood cells to the first chamber for separation of the blood components; adjusting the difference in volumetric flow rates of the pump for the whole blood pump and the pump for platelet rich plasma in response to the sensing of red blood cells; repeating the above steps until a desired volume of whole blood has been processed, and stopping operation of the centrifuge device and removing the second chamber with platelets therein from the apparatus.

Abstract: A two-staged venous cannula is disclosed having an angled bend near the distal end. In a preferred embodiment, the angle is a right angle. The angle bend allows the cannulation to take place near the junction of the inferior vena cava and the right atrium instead of higher in the right atrium. The cannula has a drainage hole at the apex of the angled bend to act as a blood collection port and a drainage hole at the distal end of the cannula to drain the inferior vena cava. The two-stage venous cannula is made of a rigid material at its distal end so that the distal end of the cannula may be easily inserted into the patient's heart through the right atrium. The disclosed cannula keeps the cannula away from the aorta, allows the cannula to exit the superior vena cava at an angle more perpendicular to the axis of the superior vena cave and allows the cannula to be used in minimally invasive surgical procedures where size and access restrictions often make it difficult to place and maintain such devices.
Abstract translation: 公开了一种两级静脉插管，其在远端附近具有成角度的弯曲。 在优选实施例中，角度是直角。 角度弯曲允许插管在下腔静脉和右心房的交界处发生，而不是在右心房较高。 插管在成角度的弯曲部的顶点处具有排水孔，以用作血液采集端口，并且在套管的远端处排出孔以排出下腔静脉。 两级静脉插管在其远端由刚性材料制成，使得套管的远端可以容易地通过右心房插入患者的心脏。 所公开的插管使套管远离主动脉，允许套管以更垂直于上腔静脉轴线的角度离开上腔静脉，并允许套管用于微创外科手术，其中尺寸和进入限制 经常使得难以放置和维护这样的设备。
