| balloon-tip catheter | A tube with a balloon at its tip that can be inflated or deflated without removal after installation; the balloon may be inflated to facilitate passage of the tube through a blood vessel (propelled by the bloodstream) or to occlude the vessel in which the tube alone would allow free flow; such catheter's are used to enter the pulmonary artery to facilitate haemodynamic measurements or to enter arteries and then remove them while inflated to withdraw clots (embolectomy catheter).

| catheter ablation | Removal of tissue with electrical current delivered via electrodes positioned at the distal end of a catheter. Energy sources are commonly direct current (dc-shock) or alternating current at radiofrequencies (usually 750 khz). The technique is used most often to ablate the av junction and/or accessory pathways in order to interrupt av conduction and produce av block in the treatment of various tachyarrhythmias.
