Pacemaker - Medtronic, Thera, 1995 Object Reg. No: ST 044044

Pacemaker, model type Thera, manufactured by Medtronic in 1995. Includes leads and the stylet used for guiding leads through the heart valves. Titanium case with epoxy fittings and two titanium tipped leads. Has an expected battery life of up to 20 years. Contains silicon chip allowing for computer-controlled monitoring and adjustement. Also includes small torsion wrench for attaching leads to pacemaker.

The unit is inserted surgically above the pectoral muscles under the clavicle. Leads are threaded from the pacemaker to the left side of the heart - one to auricle and one to ventricle.

A pacemaker (or artificial pacemaker) is a device which uses electrical impulses, delivered by electrodes contacting the heart muscles, to regulate heart beat. It maintains an adequate heart rate, either because the heart's native pacemaker cells are not fast enough, or there is a block in the heart's electrical conduction system. Modern pacemakers are externally programmable.
Comprised of several parts including: titanium case, multiple leads, stylet and silicon chip. Also includes small torsion wrench for attaching leads to pacemaker.
