发明名称 Electrode irrigation using micro-jets
摘要 A medical device includes an insertion tube, which has a distal end for insertion into a body of a subject, and a distal tip, which is fixed to the distal end of the insertion tube and is coupled to apply energy to tissue inside the body. The distal tip has an outer surface with a plurality of circumferentially distributed perforations formed therethrough. The perforations have diameters between 10 μm and 25 μm. A lumen passes through the insertion tube and delivers a cooling fluid to the tissue via the perforations.

主权项 1. A medical device, comprising: an insertion tube, having a distal end for insertion into a body of a subject; a distal tip, which is fixed to the distal end of the insertion tube and is coupled to apply energy to tissue inside the body, and which has an outer surface with a plurality of perforations formed therethrough, the perforations being distributed circumferentially and longitudinally over the distal tip and having diameters between 10 μm and 25 μm; and a lumen passing through the insertion tube and coupled to deliver a fluid to the tissue via the perforations.
