| Intravascular Diagnostic Catheters |
 |
| Goodtec (left heart) Angiography Catheter |
|
| Goodtec's Angiography Catheter is used in cardiac catheterization, for
coronary artery, left ventricle or aortic angiography, measurement of left
ventricle or aortic pressure, drawing of blood and/or fluid administration.
To satisfy each of these various purposes, Goodman maintains a large range
of models to meet the demands of physicians. |
|
| Goodtec Thermodilution Catheter |
|
| Goodtec's Thermodilution catheter is designed to quickly and accurately
measure cardiac output with the thermodilution method, and is used in catheter
lab and at the bedside. Additionally, measurements of right atrium pressure,
pulmonary artery pressure, pulmonary artery wedge pressure and drawing
of blood from the right atrium and pulmonary can be conducted with this
catheter. |
|
| Goodtec Sheath Introducer |
|
| Goodtec's Sheath Introducer was developed as an insertion device for catheters,
but it is presently used for catheter insertion into the heart, abdomen,
head and other major points. For example, it is used in cardiology for
the multiple catheters employed for angiography, and it is indispensable
device in intervention. |

| Medical Diagnostic Equipment |
|
| Volcano Intravascular Ultrasound Imaging System |
|
| An intravascular ultrasound imaging system is composed of a disposable
catheter (a slender tube) equipped with a transducer (the oscillation device
that transmits and receives ultrasonic waves), the patient interface module,
and the system console that displays the image. The catheter is advanced
intravascularly, and the system provides an image diagnosis of the tissue
characteristics of a vascular cross-section. Before the advent of this
technology, intravascular tissue conditions could only be seen after removal
from the body. With this equipment, one can see structures like cholesterol
deposits in atherosclerotic lesions as if held in the hand, and treatment
techniques have come to be determined through this imaging diagnosis. Also,
application of this system can assist in the safe and accurate stent treatment
to protect against restenosis. |
|
| FloMap / FloWire |
|
| Volcano's FloMap and FloWire system is equipment used to inspect the function
of a patient's heart. It uses Doppler ultrasound signals to measure coronary
artery bloodflow speed, volume and coronary flow reserve, which have a
direct connection to coronary conditions like myocardial infarction. When
a coronary artery becomes blocked, the FloWire can be used as a guide for
the balloon to perform PTCA treatment. Furthermore, as there is an ultrasonic
transducer at the tip of the wire, it can be connected to the FloMap system
as necessary to observe the current status of circulation in the coronary
artery. As FloMap can calculate many indicators instantly, it serves as
a guideline for balloon and other coronary treatments, evaluating the necessity
of treatment, the occurrence of complications, study of treatment methods,
and decisions on therapeutic value and patient prognosis. Finally, the
FloMap and FloWire system is not limited to measuring coronary bloodflow,
but is also used for examination and treatment in fields such as neurology
and pediatrics. |
|
| WaveMap / SmartMap / SmartWire |
|
| Volcano's WaveMap: Pressure Guidewire system uses a guidewire equipped
with a piezo resistance pressure sensor allowing for intravascular blood
pressure measurement at any point. |
|
| The SmartWire that can be connected and used with this system is a 0.014
inch (0.35mm) guidewire with excellent operability. It can be used as a
guide for a balloon catheter while providing continuous real-time monitoring
of coronary artery blood pressure. Furthermore, by inputting a signal into
the aorta from an external Polygraph with WaveMap, various indices can
instantly be calculated and expressed. Regarding angina pectoris and heart
attacks resultant from coronary artery contraction in ischemic heart disease,
blood pressure measurement throughout the lesion allows for the evaluation
of the stenosis's physiological severity, assisting quick and easy treatment
planning, treatment method examination and judgment of treatment results. |

| Artificial Organs |
|
| Thoratec's Polyurethane Artificial Vessel (for dialysis use) |
|
| Thoratec's Polyurethane Artificial Vessel is used as a dialysis shunt and
received approval from pharmaceutical affairs in May of 1997. Previously,
e-PTFE was the only material employed for dialysis-use in the clinical
setting, and this artificial vessel that uses polyurethane was the first
of its kind approved in this country. Thoratec's product overcomes the
disadvantages of artificial vessels that use e-PTFE, such as the inability
to perform dialysis soon after the operation and poor stypticity to become
an artificial vein graft better suited for dialysis. Due to increases in
aging dialysis patients and those with diabetic nephropathy, the need for
vein grafts is growing more and more. With these circumstances in mind,
it is anticipated that this vein graft will improve the quality of life
for dialysis patients. |
