Abstract
The utility model relates a pacemaker electrode of the implantable cardiac pacemaker, whose head is coated with a layer of the metal iridium. A layer of metal iridium is coated on the head of the pacemaker electrode of the utility model, which forms multi-layers spherical accumulation in microcosmic level, thus the perception area is increased more than 100 times, the stimulating area can be made very small, furthermore, both the stimulating threshold value and the sensing function can achieve satisfactory results.
Description
Technical field
This utility model relates to a kind of implantable cardiac pacemaker pacing electrode.
Background technology
The implantable cardiac pacemaker is made up of pulse generator and pacing electrode catheter, the pulse signal that pulse generator takes place transfers to heart and cardiac stimulus pace-making via pacing electrode catheter, and the exciting signal of heart also is sent to cardiac pacemaker by pacing electrode catheter.Requirement to pacing electrode in the clinical treatment is: stimulate area to want little so that local current densities increases and reduce pacing threshold, save the energy, prolong cardiac pacemaker service life; Require perception face to want big simultaneously, transmit real electrocardiosignal to cardiac pacemaker so that can detect the stress of heart preferably.Research in the past all is to select some special alloy materials, and electrode tip is made certain shape, and as hemispherical, circular, netted etc., but effect is very undesirable.
Summary of the invention
The technical problem that this utility model solves: design a kind of implantable cardiac pacemaker pacing electrode, the perception area of pacing electrode head is increased more than 100 times, and stimulate area very little, stimulate threshold values and perceptive function all can obtain satisfied effect.
Technical solution of the present utility model: a kind of implantable cardiac pacemaker pacing electrode is coated with layer of metal iridium (2) on its electrode head (1).
This utility model compared with prior art is coated with layer of metal iridium on its electrode head, formed the globular accumulation of multilamellar on the microcosmic, make the perception area of pacing electrode head increase more than 100 times, not only stimulate area to make very for a short time, and stimulate threshold values and perceptive function all to obtain satisfied effect.
Description of drawings
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is a structure cut-away view of the present utility model.
The specific embodiment
1,2 a kind of embodiment of the present utility model is described in conjunction with the accompanying drawings.
A kind of implantable cardiac pacemaker pacing electrode is coated with layer of metal iridium (2) on its electrode head (1).During use, the doctor proceeds to when interting this operating procedure of pacing electrode catheter in clinical practice, sign according to requirement of cardiac pacemaker operation instructions and cardiac pacemaker, the cardiac pacemaker pacing electrode catheter that will implant inserts the cardiac stimulation position by the treatment operative procedure from selected vein blood vessel and settles, and finishes whole operations by the treatment content and get final product.
Claims (1)
1, a kind of implantable cardiac pacemaker pacing electrode is characterized in that: be coated with layer of metal iridium (2) on the described electrode head (1).
