Transcatheter Occlusion Device is indicated for the non-surgical closure of patent ductus arteriosus. Transcatheter occlusion device is designed to reduce the risk of stroke by occluding the left atrial appendage, a small pocket attached to the hearts left upper chamber that has limited functional use and is the location of a majority of blood clots in the heart.

Transcatheter pulmonary valve is a breakthrough non-surgical means to treat a complication associated with congenital heart disease. It is designed to benefit patients with congenital heart defects involving the connection between their right ventricle and pulmonary artery. It is also used to treat congenital patients with structural heart disease requiring pulmonary heart valve replacement.

Transcranial doppler is a test that measures the velocity of blood flow through the brain's blood vessels. It is useful in assessing intracranial blood flow and for following the status of vascular lesions over time, not in the setting of evolving neurologic compromise. It helps in the diagnosis of emboli, stenosis, vasospasm from a subarachnoid hemorrhage, and other problems.

Transcranial ultrasound doppler is a non-invasive ultrasound method used to examine the blood circulation within the brain. During TCD, sound waves, inaudible to the human ear, are transmitted through the tissues of the skull. These sound waves reflect off blood cells moving within the blood vessels, allowing the radiologist to calculate their speed. The sound waves are recorded and displayed on a computer screen.

Transcutaneous Electrical Nerve Stimulator is an electronic device that produces electrical signals, which is used to stimulate nerves through unbroken skin. Transcutaneous electrical nerve stimulator is designed specifically for post operative pain control. Transcutaneous electrical nerve stimulator is used in acute and chronic pain. It is a medical method of reducing or eliminating pain without drugs.

Transcutaneous oximetry is a noninvasive test. It directly measures the oxygen level of tissue beneath the skin. As oxygen is carried to tissues by blood flow in the arteries, TcpO2 is an indirect measure of blood flow. It measures the amount of oxygen that reaches the skin through blood circulation. Measuring oxygen at the skin surface is a valuable indicator of how much oxygen gets to underlying tissues. Transcutaneous oximetry is useful when other noninvasive testing is not possible and is especially useful in predicting wound healing or amputation healing.
