The interspinous distraction devices of the present invention are designed and configured to effectively treat such conditions as lumbar spinal stenosis and degenerative disc disease. Advantageously, the interspinous distraction devices of the present invention may be inserted through conventional open procedures, typically requiring a relatively large incision and a general anesthetic, or through novel minimally-invasive procedures, typically requiring only a local anesthetic. These novel minimally-invasive procedures and related enabling devices are also disclosed and described herein.

A method and apparatus to monitor the neurologic state of a patient undergoing general anesthesia is provided. Previous automated systems to monitor the neurologic state of a patient undergoing general anesthesia involve a significant time delay between the patient's true hypnotic state and the computed indices. The present invention reduces this time delay by using a different analysis technique applied to spontaneous EEG. A wavelet decomposition and statistical analysis of the observed EEG is conducted and compared to reference data to provide a numerical indicator. In addition, this indicator is more consistent with the patient's loss of consciousness indicated by the loss of count event than previous systems.

Drug delivery devices are also disclosed that include the use of stored parameters and/or values that correlate to drug mixture delivery during a procedure, and a patient health monitor to measure and send signals regarding a patient health condition to a processor.

Described are equipment, a system, a kit and a method for the performance of a minimally-intensive body access, such as cardiac access. Epicardial Access Surgery (EAS) is disclosed. EAS does not need general anesthesia or extracorporeal circulation nor does it need a chest opening, which is very advantageous for various aspects. For instance an operation of a coronary artery bypass is created by creating a direct path of flow from one body artery into a coronary artery with the aid of catheter-based minimally-invasive EAS based bypass surgery. In addition, various medical devices are used, such as a special partially flexible needle, a special partially covered stent, and a special partially flexible port.

A method and apparatus are provided for ventilation of patients during general anesthesia. Breathing gas is supplied to the patient during anesthesia at a controlled volume above the functional residual capacity of the patient's lungs. The patient is allowed to spontaneously respire when the volume of breathing gas is above the functional residual capacity. The pressure of the breathing gas is periodically reduced to facilitate expulsion of carbon dioxide-containing gas from the patient. The system promotes alveolar ventilation, carbon dioxide excretion, oxygenation and respiratory monitoring in patients who receive general anesthesia.

A controllable intubating stylet (CIS) for use by anesthesia and other health care providers is used in conjunction with a video laryngoscope and endotracheal tube in order to achieve intubation of the trachea for general anesthesia as well as other medical conditions. The video laryngoscope is used to visualize the tracheal opening. The CIS is inserted into an endotracheal tube and directed into the trachea. The endotracheal tube then is maneuvered over the stylet and into the trachea, and thereafter, the CIS is removed. The patient can then be oxygenated and ventilated by way of the endotracheal tube. The CIS includes a control mechanism similar to current bronchoscopes which allows for flexion of the tip and overall flexibility of the stylet. In contrast to the bronchoscope, however, the CIS includes no fiberoptics or associated components, such as a light source or eyepiece, making the CIS much less expensive to produce.
