    摘要： An implantable lead fixation apparatus, including two suture collars connected by a flexible retaining member of predetermined length, is provided for anchoring an elongate cylindrical electrode lead to a patient's body. Each suture collar comprises a flexible annular member having a central lumen that is adapted to enclose the lead. The suture collars each include provision for securing the lead against longitudinal movement of the lead with respect to the collar, and provision for anchoring the collar to the patient's body. The suture collars are positioned relatively proximally and distally with respect to the lead, and are secured on the lead with the proximal suture collar being separated from the distal suture collar by slightly less than the length of the retaining member. Then, the lead fixation apparatus is positioned with respect to the patient's body and secured to the body so that the proximal suture collar is located at a selected distance less than the predetermined distance from, and at an angular orientation to, the distal suture collar to provide slack in both the lead and the retaining member in order to accommodate patient movement without applying dislocating forces to a distal portion of the lead.

    摘要翻译： 提供了一种可植入引线固定装置，其包括通过预定长度的柔性保持构件连接的两个缝线环，用于将细长圆柱形电极引线锚定到患者身上。 每个缝合线圈包括柔性环形构件，其具有适于包围引线的中心腔。 每个缝线圈包括用于固定引线以防止引线相对于套环的纵向运动的设置，以及用于将套环固定到患者身体的部件。 缝合线圈相对于引线相对近端和远端定位，并且被固定在引线上，其中近端缝合线圈与远端缝合线圈相距稍微小于保持构件的长度。 然后，引导固定装置相对于患者的身体定位并固定到身体，使得近端缝合线圈位于小于距离远端缝合线圈到角度定向的预定距离的选定距离处， 在引线和保持构件两者中提供松弛，以便适应患者运动而不将脱位力施加到引导件的远端部分。

    摘要： A method for exchanging heat with a patient's spinal column incident to spinal surgery or to relieve a patient for a hypoxia condition of the spine. A closed loop heat exchange catheter is percutaneously advanced into the retroperitoneal space of the patient, and then heat exchange fluid is circulated through the catheter to cool the spinal column.

    摘要： A cardioverting/defibrillating pacemaker with the ability to sense and respond to haemodynamic compromise. The ventricular pressure (VP) and electrical activity of the heart are sensed via one or more transvenous or epicardial devices. The filtered peak-to-peak amplitude (VFPPA) or a peak pressure function (VPPF) based upon the right and/or left VP waveform(s) are derived. In one embodiment the VP and the electrical activity of the heart are sensed and processed continuously, and the VFPPA or the VPPF continuously derived. The VFPPA or the VPPF, and the ECG are used to initiate bradycardia pacing, antitachycardia pacing and cardioversion/defibrillation therapies. In another embodiment the VP and electrical activity of the heart are continuously sensed. The electrical activity is processed continuously and used to determine whether or not some irregularity exists. If so, one of the VPPF or VFPPA is derived and used to decide which of the therapies are to be used. One of the VPPF or VFPPA is also periodically determined to ensure optimal haemodynamic function. In both emobidments the degree of haemodynamic compromise is determined by comparing the derived VFPPA or VPPF with programmed values. An algorithm maximizes the effectiveness of support pacing. Preferably an ECG transvenous sensor in the right atrium and a combined ECG/VP sensor in the right ventricle are used.

    摘要： A combined occlusion/infusion catheter is placed in the aorta of a cardiac arrest patient to occlude the aorta at a location just above the renal arteries/celiac trunk while rapidly infusing a liter or more of cold saline into the aorta below the occlusion. This flushes white cells from the bowel (now placed into a state of hypothermic stasis) induces hypothermia in the whole body, with perfusion pressure of the cold fluid maximized to the brain.
