A delivery system and method for percutaneous aortic valve (PAV) replacement and apparatus used therein. A temporary aortic valve comprised of a reversibly expandable occluding means, such as balloons, surrounds a central catheter mechanism. The temporary valve is positioned within the ascending aorta, just above and downstream from the coronary ostia. The occluding means is configured such that, when fully expanded against the aortic wall, gaps are left that promote continuous coronary perfusion during the cardiac cycle. The temporary valve with occluding means substitutes for the function of the native aortic valve during its replacement. The native aortic valve is next dilated, and then ablated through deployment of low profile, elongated, sequentially delivered stents. The ablation stent(s) displace the native valve tissues and remain within the aortic annulus to receive and provide a structure for retaining the PAV. The PAV is delivered, positioned and deployed within the ablation stent(s) at the aortic annulus with precision and relative ease. Ablation of the native aortic valve removes the structural obstacles to precise PAV placement. The temporary aortic valve mediates the hemodynamic forces upon the devices as encountered by the surgeon following native valve ablation. The temporary valve also promotes patient stability through continuous coronary perfusion and a moderated transvalvular pressure gradient and regurgitation. Sequential delivery of low profile PAV components minimize the risk of trauma and injury to vascular tissues. Mathematical considerations for determining the optimum cross-sectional area for the temporary valve blood perfusion gaps are also described.

A method for cerebral and systemic cooling by circulating a cold liquid through a nasal catheter looped through the patient's nasal cavities and around the nasal septum. The nasal catheter is inserted into the patient's first nostril, advanced through the nasal cavity, around the nasal septum and out of the patient's second nostril. A cold fluid having a temperature between about −20° C. and about 37° C. is flowed though a lumen in the nasal catheter to cool the nasal cavity. The nasal catheter may have one or more flexible balloons mounted on the catheter such that when the catheter is looped around the nasal septum, the balloon(s) are positioned in a portion of the patient's first and second nasal cavities. When a cold liquid is circulated through the catheter lumen, the flexible balloons expand to a contact the inner walls of the nasal cavities and provide direct cooling of the nasal cavities.

The invention discloses a zoning tissue engineering spinal cord which comprises a spinal external catheter and a central catheter. A gray matter catheter which is provided with the same shape as spinal gray matter is arranged in the spinal external catheter. Corresponding catheters are respectively arranged in a white matter region according to the geometric shapes of uplink fiber bundles and downlink fiber bundles. The zoning tissue engineering spinal cord can play the role of correct guidance and lead to the result that the spinal gray matter, white matter and the uplink fiber bundles and the downlink fiber bundles in the white matter respectively grow in different regions.

A medical drape (100) includes an upper portion (101) and a lower portion (102). The upper portion (101) can be pellucid, while the lower portion (102) can be opaque. To facilitate central catheter insertion, the upper portion (101) can define one or more apertures (104,105) through which a central line may be inserted. A tourniquet (401) may be integrated with the drape, as can one or more tool-less removal features (108,109).

The invention relates to the technical field of medical instruments, and discloses an automatic medicine bottle continuing and convenient-to-adjust infusion support. The infusion support comprises a support body, wherein a lever is rotatably connected to the top of the support body, a balancing weight is fixedly connected to the left end of the lever, and a pull rope is fixedly connected to the bottom end of the balancing weight; the bottom end of the balancing weight is in transmission connection with a balancing weight through a pulley block, and the interior of the right end of the lever ismovably connected with a telescopic rod. According to the infusion support capable of automatically splicing the medicine bottles and convenient to adjust, the lever rotates upwards to enable the contacts to be communicated, the corresponding electromagnets are excited to be communicated, and the next infusion bottle and the central catheter are communicated, so the effect of automatically splicing the medicine bottles to reduce working intensity of medical staff is achieved, and medicine changing efficiency is improved; balance weight is selected according to infusion bottles of different specifications, alarm and medicine adding positions of the different infusion bottles can be adjusted conveniently, and universality of the device is improved.

The invention relates to determining a representation of cardiac output in a patient. Provided are a method and a system for monitoring a cardiac output using a single device inserted into a Central Venous Catheter (CVC) or Peripheral Inserted Central Catheters (PICC) line. In an embodiment, the device contains an elongated body that fits the lumen of a Central Venous Cava or Peripheral Inserted Central Catheters line and has an ultrasound transducer at the tip. By operating the device such that the velocity in both the Superior Vena Cava and Inferior Vena Cava can be sampled continuously the CO is monitored.

The invention relates to a peripherally inserted central catheter, which comprises a catheter and a closed needle-less infusion connector, wherein the catheter is connected with the closed needle-less infusion connector by a connecting device; and a catheter cut is formed on the catheter wall at a position deviating from the central axial surface of the catheter. The catheter cut is naturally closed when the blood is not drawn back and the liquid medicament is not transfused or injected, a negative pressure is generated in a catheter cavity when the blood is drawn back by medical personnel, the large lip of the catheter cut sinks inwards; a positive pressure is generated in the catheter cavity when the liquid medicament is injected or transfused by the medical personnel, the large lip of the catheter cut bulges outwards; therefore, the catheter cut functions as a two-way catheter valve and is used as the inlet and outlet for the liquid medicament transfusion and injection and the effective opening is formed to facilitate liquid medicament injection and transfusion. The peripherally inserted central catheter has the advantages of simple structure, convenient use, good liquid controllability over the medicament transfusion and injection and capability of avoiding catheter blockage.
