Lungavita™ Veterinary Cardiac Pacemaker and Programmer

Lungavita™ pacemakers are implantable, single-chamber, rate responsive pulse generators that are intended to improve cardiac output in bradycardic patients. Lungavita™ generators are multi programmable, meaning that the veterinary cardiologist can set a variety of parameters to best determine their functionality according to the patient’s needs.  The programming system has the ability to modify the parameters of the device and to retrieve diagnostic information that is stored in the generator. Lungavita™ pacemakers are connected to a single lead with IS1-BI/UNI connectors.  The telemetric communication with the pacemaker can be performed only by means of the Lungavita™ programming system. Second generation Lungavita™ pacemakers are only compatible with second generation Lungavita™ programming systems.

Programmer:

This is a portable pacemaker programmer equipped with an LED screen and a software interface that allows simple and immediate access to various functions.  The programming head, connected by cable to the main unit, is able to perform telemetric programming at 100 KHz. Programming and interrogation operations are performed by using the associated touch screen functions.
