|---|---|
| self-retaining catheter | A catheter so constructed that it remains in urethra and bladder until removed, e.g., indwelling catheter; Foley catheter. (05 Mar 2000) |
| spiral tip catheter | A catheter with a helical filiform tip. (05 Mar 2000) |
| Nelaton's catheter | A flexible catheter of red rubber. (05 Mar 2000) |
| subclavian catheter | <equipment> Small, flexible plastic tube inserted into the large vein above the heart, through which drugs and blood products can be given and blood samples withdrawn painlessly. Synonym: central line, Hickman catheter. (12 Jan 1998) |
| Swan-Ganz catheter | <equipment> A special haemodynamic monitoring device (long thin catheter) that is introduced into a large vein (in the neck, chest or groin) and advanced through the right heart to the pulmonary artery. Measurements of cardiac function and blood pressure can be made with this device that can greatly increase the physician's diagnostic ability and provide a way to monitor the patients response to different medications. May be used to diagnose pulmonary hypertension. (19 Jan 1998) |
| de Pezzer catheter | A self-retaining catheter with a bulbous extremity. (05 Mar 2000) |

| indwelling catheter | A catheter left in place in the bladder, usually a balloon catheter. (05 Mar 2000) |
| intracardiac catheter | <cardiology> A catheter that can be passed into the heart through a vein or artery, to withdraw samples of blood, measure pressures within the heart's chambers or great vessels, and inject contrast media. It is used mainly in the diagnosis and evaluation of congenital, rheumatic, and coronary artery lesions and to evaluate systolic and diastolic cardiac function. Synonym: cardiac catheter. (05 Mar 2000) |
| olive-tipped catheter | A ureteral catheter with an olive-shaped tip, used to dilate a constricted ureteral orifice; larger sizes are also used for dilating or calibrating urethral strictures. (05 Mar 2000) |
| elbowed catheter | A catheter with an angular bend near the beak; used to rise over prostatic obstruction. Synonym: catheter coude, prostatic catheter. (05 Mar 2000) |
| electrode catheter ablation | A method of ablating the site of origin of arrhythmias whereby high energy electric shocks are delivered by intravascular catheters. (05 Mar 2000) |
| eustachian catheter | A catheter used for catheterization of the middle ear through the eustachian tube. (05 Mar 2000) |
