A system and method for Brugada syndrome epicardial ablation comprising preparing an endocardial duration map; preparing a baseline epicardial duration map comprising at least one or more areas of delimination; and when some of the areas of delimination are greater than 200 ms, performing epicardial ablation of the areas of delimination greater than 200 ms. The method may further comprise preparing an updated epicardial duration map after performing epicardial ablation, and determining whether or not a BrS pattern appears in the updated epicardial duration map; and when the BrS pattern appears, performing epicardial ablation. The method may further comprise preparing an updated epicardial duration map after performing epicardial ablation, and determining whether or not an abnormal EGM exists in the updated epicardial duration map; and when the abnormal EGM exists, performing epicardial ablation. The method may further comprise preparing an updated epicardial map comprising maintaining anatomical volume data and adding electroanatomical data.

A connector block that permits simultaneous and continuous interconnection of the three leads of the epicardial pacing wires, the pacemaker, and the ECG monitor on clear separately labeled connectors is provided. Circuitry is provided that allows the display of epicardial signals on the telemetry unit, while still preserving the ability to pace the heart from the pacemaker. When pacing the connector block prevents excessive loading of the pacer signals by the ECG monitor and/or damage to the monitor by the high-voltage pacer signals. The connector block may be used universally on all monitors without the need for sophisticated understanding of the electrical characteristics of the ECG monitor or concern for damage or improper signal loading.

A defibrillation system with a unique paddle assembly. The paddle assembly has a paddle head with a conductive surface. The paddle head is introduced into the chest through a small surgical incision. The paddle head is connected to a handle by an elongated shaft. The elongated shaft has an electrically conductive core that is covered in a dielectric insulator. The elongated shaft is malleable. A pivot connection joins one end of the elongated shaft to the paddle head. The pivot connection enables the paddle head to move through a range of different orientations with respect to the elongated shaft. Electricity passes through the conductive core of the elongated shaft and into the paddle head.

An improved system for temporary cardiac pacing addresses the problem associated with heart tissue damage caused by removal of the temporary pacing leads. In the improved system the leads biodegrade and thus need not be removed. This, in turn, allows the surgeon to attach the leads more firmly to the heart.

This document provides devices and methods for the treatment of heart conditions. For example, this document provides a percutaneous temporary epicardial pacemaker device and system for treating heart arrhythmia.

Devices or methods such as for stimulating excitable tissue or sensing physiologic response or other signals that can use separate fixation mechanism is described. An implantable apparatus can include a modular electrostimulation electrode assembly that can include a first module and a second module that can be end user-attachable to each other and end user-detached from each other. The first module can include an electrostimulation electrode fixation support member that can be laid flat against or otherwise conform to a surface of a heart, and can define a centrally located open portal such as for permitting electrode access to the surface of the heart. The second module can include an electrostimulation electrode that can be inserted through the portal of the fixation support member such as to contact the surface of the heart such as to deliver chronic electrostimulation to the heart.

An electrode arrangement, for the temporary stimulation or defibrillation of the heart includes at least one unipolar electrode configured to be secured on the myocardium of the heart. An indifferent electrode is configured to be secured on the inner wall of the thorax via its supply line and be positioned such that direct contact with the heart is prevented. An external pacemaker is in electronic communication with the at least one unipolar electrode and the indifferent electrode such that negative poles of the indifferent electrode are combined into a single cable.

In some embodiments, a portable interface for a temporary external pacemaker comprising a housing, a communication module disposed in or on the housing for communicating with a pacemaker generator, and a display coupled to the housing, the display having a graphical interface to visualize a patient's heart rhythm and a sensitivity overlay that correlates with a sensitivity setting.

A medical device includes a printed circuit board, a connector mounted on the printed circuit board, and a polymeric body molded over the connector and the printed circuit board. The connector is configured to receive a medical lead and electrically and mechanically couple the lead to the printed circuit board. The connector comprises a housing and feedthrough assembly that includes a polymeric housing and a conductor. The housing defines a bore configured to receive the lead and defines a feedthrough opening through which the conductor extends. The housing and feedthrough assembly is sealed except for an aperture in communication with the bore. The connector further includes a contact disposed in the bore. The conductor electrically couples the contact with the printed circuit board. When a lead is properly received by the bore, the contact couples the lead to the printed circuit board via the conductor.

A device for use during cardiothoracic surgery around the heart of a patient. The device includes an angled drainage tube including a first portion having a plurality of drainage orifices and a second portion which is angled relative to the first portion. A flexible drainage tube extends from the angled tube and is in fluid communication therewith. A pair of pacing electrodes are disposed on a single aspect of the first portion of the angled drainage tube. The pacing electrodes are adapted to be in contact with the heart muscle for intrinsic rhythm sensing and pacing capability thereof. At least one electrical wire is connected to the pacing electrodes and extends along a portion of the angled drainage tube. The at least one electrical wire is connectable to a pacing box via a cable for powering and controlling the pacing electrodes.
