    • The cannula of the present invention is useful for standard gravity drainage or vacuum assisted/suction drainage. The cannula of the present invention has a flexible shaft composed of a tubular body and an expandable scaffolding. The expandable scaffolding has a contracted position, facilitating insertion into a vessel and an expanded condition configured to allow optimal drainage in a vessel. The cannula is inserted into a vessel and navigated into an operative position within the patient's venous system. Once the cannula is in the proper position, the scaffolding is expanded either through passive, active, mechanic, hydraulic, pneumatic, thermal or electrical actuation. The cannula of the present invention is capable of expanding a collapsed vein to its normal diameter and/or capable of supporting the vein when suction is applied to the cannula to help increase fluid flow through the cannula.

    • A circulatory support system and method for circulatory support are described for performing cardiopulmonary bypass using differential perfusion and/or isolated segmental perfusion of the circulatory system. The circulatory support system includes one or more venous cannulae for draining blood from the venous side of the patient's circulatory system, one or more arterial cannulae for perfusing the arterial side of the patient's circulatory system, and one or more blood circulation pumps connected between the venous cannulae and the arterial cannulae. The arterial cannulae and the venous cannulae of the circulatory support system may take one of several possible configurations. The circulatory support system is configured to segment a patient's circulatory system into one or more isolated circulatory loops. The circulatory loops may be isolated from one another and/or from the remainder of the patient's circulatory system on the venous side, as well as on the arterial side, for isolated closed loop circulatory support of separate organ systems. The circulatory support system is suitable for use in minimally-invasive cardiac surgery, using thoracoscopic, port-access or minithoracotomy techniques, or for standard open-chest cardiac surgery.

    • A method and device for perfusing an organ system is provided. The device may be further described as a catheter or cannula with an expandable flow control member positioned of the distal portion of the catheter shaft. The flow control member has a porous portion, and at least one impermeable portion, which prevent fluid from flowing out the ends of the flow control member. The flow control member is further characterized as having an interior chamber that is in fluid communication with a perfusion lumen that extends along the length of the catheter shaft and is in fluid communication with an external perfusion pump. The perfusion lumen is configured for providing flow to the interior of the flow control member, to create radial expansion thereof and to provide adequate flow to the arch vessels through said porous portion to sustain the metabolic demands of the brain.

    • A system and methods are described for performing catheter based procedures on high risk patients that mitigate the risk to the patient and extend the acceptable time window for response when emergencies or complications arise. The system is useful for stopped heart catheter procedures or as a safety backup in beating heart catheter procedures and is compatible with concurrent or sequential surgical interventions. The system combines a therapeutic or diagnostic catheter subsystem with a selective aortic perfusion and cardiopulmonary bypass subsystem. The catheter subsystem may include catheters for angioplasty, stent delivery, atherectomy, valvuloplasty or other diagnostic or therapeutic procedures. The selective aortic perfusion and cardiopulmonary bypass subsystem generally includes catheters and/or cannulas for draining blood from the patient's venous or arterial system, a perfusion pump, a blood oxygenator, at least one blood heat exchanger and catheters and/or cannulas for perfusing oxygenated blood into the patient's arterial system. The arterial perfusion catheters and/or cannulas are constructed with an upstream flow control member located in the patient's ascending aorta and a downstream flow control member located in the patient's descending aorta. The external flow control members may take the form of inflatable occlusion balloons and/or selectively deployable external catheter flow control valves. The external flow control members may be mounted on a single elongated catheter or cannula shaft or they may be mounted on separate catheter or cannula shafts for independent placement and deployment.

    • The present invention discloses a multi-access cannula for use in a variety of surgical procedures, particularly for use in the course of performing conventional open-chest and peripheral access cardiopulmonary bypass (CPB). The multi-access cannula is capable of being inserted through a single puncture site with a percutaneous tip. At the appropriate depth of insertion, a closure seal may be engaged at the point of entry to secure the positioning of the cannula and prevent leakage of blood from the incision. Once the cannula is at the appropriate position the cannula provides a multiplicity of procedural options for the surgeon. For example, when approaching through the ascending aorta, the multi-access cannula enables the simultaneous passage of various fluids and multiple catheters or instruments in opposing directions within the lumen of the aortic arch through a single insertion site.
    • 本发明公开了一种用于各种外科手术的多通道插管,特别用于执行传统胸腔和外周进入体外循环(CPB)的过程中。 多通路插管能够通过具有经皮尖端的单个穿刺部位插入。 在适当的插入深度处,封闭密封件可以在入口处接合以固定套管的定位并防止血液从切口泄漏。 一旦插管位于适当的位置,套管为外科医生提供了多种程序选择。 例如,当通过升主动脉接近时,多通路套管能够通过单个插入位点同时通过主动脉弓内腔内的相反方向的各种流体和多个导管或器械。
