2000 results about "Anesthesia" patented technology

Anesthesia or anaesthesia (from Greek "without sensation") is a state of controlled, temporary loss of sensation or awareness that is induced for medical purposes. It may include analgesia (relief from or prevention of pain), paralysis (muscle relaxation), amnesia (loss of memory), or unconsciousness. A patient under the effects of anesthetic drugs is referred to as being anesthetized.

Hybrid ventilation mask with nasal interface and method for configuring such a mask

A nasal ventilation interface and method for providing nasal ventilation to a patient includes a hybrid face mask, covering only the mouth, coupled with removable nasal inserts extending from the upper surface of the mask. The nasal interface has modular, removable, and disposable nasal pillows connecting the upper surface of the mouth-portion of the mask to the user's nares. Each part of the hybrid mask is modular and can be formed in various shapes and sizes. The ventilation interface has differing gas line entry ports and can be shallow with a relatively deep soft facial interface or deep with a relatively shallow facial interface. In either case, the upper surface receives the nasal interface. The upper surface can have a removable ceiling in which is defined a nasal interface connector. The nasal interface can be integral with a removable ceiling. The entire hybrid mask can be made in one piece.

Methods and devices for minimally invasive spinal fixation element placement

Minimally invasive methods and devices for introducing a spinal fixation element into a surgical site in a patient's spinal column are provided. In general, the method involves advancing a spinal fixation element in a first, lengthwise orientation along a pathway extending from a minimally invasive percutaneous incision to a spinal anchor site. As the spinal fixation element approaches the spinal anchor site, the fixation element can be manipulated to extend in a second orientation, which is preferably substantially transverse to the first orientation, to position the fixation element in relation to one or more spinal anchors.

Method and apparatus for detecting respiratory disturbances

A system and method for monitoring respiration including sensing a signal that varies with respiration, deriving a respiration parameter, applying criteria for detecting a respiration disturbance and determining one or more respiratory disturbance metrics. The system preferably includes an implantable sensor with an associated implantable medical device such that chronic respiration monitoring is possible. The implantable medical device may execute methods for detecting and measuring respiratory disturbances or may store data to be transferred to an external device for detecting and measuring respiratory disturbances. Respiratory disturbance detection may trigger a responsive action such as physiological data storage, a change in therapy delivery, or a clinician warning. Assessment of cardiac function may be made based on metrics of respiratory disturbances or a measure of circulatory delay time following detection of a respiratory disturbance.

Devices for maintaining patency of surgically created channels in tissue

Devices and methods for altering gaseous flow within a lung to improve the expiration cycle of an individual, particularly individuals having chronic obstructive pulmonary disease. The methods and devices create channels in lung tissue and maintain the patency of these surgically created channels in tissue. Maintaining the patency of the channels allows air to pass directly out of the lung tissue which facilitates the exchange of oxygen ultimately into the blood and / or decompresses hyper-inflated lungs.

Methods and systems for selective control of bladder function

InactiveUS6990376B2Inhibiting neural transmissionStimulating neural transmissionElectrotherapyArtificial respirationNerve fibreHigh amplitude
A method and system for selective inhibition of somatic nerve fibers in a mixed nerve containing both somatic and autonomic nerve fibers where the method finds use in treatment of chronic pain, spastic muscles and for sensory and motor control of a bladder. The methods and systems utilize alternate phase rectangular electrical pulses. An electrical pulse generator is coupled to a nerve. An alternate phase high frequency, low amplitude pulse is first applied to selectively inhibit somatic nerves when present in a mixed nerve. An alternate phase low frequency, high amplitude phase pulse subsequently supplied to stimulate the autonomic nerve fibers and in the case of the sacral root will permit a controlled voiding of the bladder and bowel.
