카테터(의학: catheter)는 의료용 소재를 이용, 압출 성형하여 만든 얇은 관으로 의학 분야에서 다양한 기능으로 쓰이고 있다. 카테터는 병을 다루거나 수술을 할 때 인체에 삽입하는 의료용 기구이다. 카테터는 인체의 강, 관, 혈관에 삽입할 수 있다. 배액, 액체, 기체를 투여할 때나 수술용 기구를 이용하여 접근할 때 쓰이고, 이 밖에도 카테터의 종류에 따라 다양하게 사용되고 있...
Peripherally inserted central catheters are increasingly used to provide short- to medium-term access to the central venous circulation. Because they are frequently left in situ for several weeks or months, and are often used for vesicant therapies, it is imperative that the catheter tip sits in an adequate position within the central circulation. They are usually inserted into the arm veins using ultrasound guidance and a Seldinger technique; however, the tip is usually blindly positioned in the central circulation using anthropometric measure ...
A catheter assembly includes a catheter, a hub, and a sealing member. The catheter defines one or more lumens. The hub includes one or more hub extensions dimensioned to be received within the one...

Description ; This invention relates to percutaneous transluminal coronary angioplasty (PTCA), and more particularly to angioplasty using balloon catheters in which the balloon allows perfusion in its inflated condition. Coronary angioplasty is a widely used alternative to open-heart coronary bypass surgery for the treatment of acute and chronic heart problems. A major contributing factor in such heart problems is a reduction in nutrient blood flow to the muscles of the heart resulting from a reduction of blood flow through the coronary blood v ...

Description ; The present invention relates to a catheter assembly insertable into a living body for biophysical (e.g. blood pressure or flow rate) or biochemical (e.g. blood pH or oxygen concentration) sensing at a region of interest. More particularly, the invention relates to compact configurations for such a catheter assembly adapting it for insertion through or into exceptionally small spaces, and for measuring multiple parameters simultaneously without sacrificing compactness. Many prior a...
Abstract : A catheter integral with a valved needle-free connector provides a safety catheter device configured to receive a blunt cannula and sharp needle forming an insertion mechanism. The sharp needle is mounted within a needle tube and a control handle is used to slide the sharp needle out of and into the protective needle tube. When the insertion mechanism is mounted to the connector and the control handle is used to slide the sharp needle out of the tube, a blunt cannula first moves into ...
