Abstract

Methods, devices, and systems for temperature management and ventricular defibrillation are disclosed. Methods, devices, and systems for positioning an electrode in the esophagus of a subject and managing the core body temperature of the subject are disclosed. The use of esophageal heat transfer devices to deliver an electrode for use in delivering an electrical shock to the myocardium is disclosed.

Core Innovation

The disclosed subject matter relates to temperature-management and ventricular defibrillation using an esophageal heat transfer device positioned within an esophagus of a subject. The esophageal heat transfer device includes a non-inflatable heat transfer region that transfers heat with the esophagus as heat transfer medium flows through the device, thereby managing core body temperature of the subject. The device architecture includes lumens defining a fluid path for flow of the heat transfer medium to enable heat transfer with the esophagus.

Electrical shock delivery is integrated with the esophageal temperature management by providing at least one electrode configured to deliver an electrical shock to a heart when positioned within the esophagus proximate to the heart. The electrode is coupled to the non-inflatable heat transfer region, enabling the electrode to deliver the electrical shock from within the esophagus simultaneously as the non-inflatable heat transfer region transfers heat with the esophagus for managing the core body temperature. An electrode lead wire includes a distal end coupled to the electrode to enable delivery of the electrical shock.

The system further includes an external reservoir capable of storing the heat transfer medium that provides heat transfer medium to the esophageal heat transfer device through a supply pathway and returns heat transfer medium to the external reservoir via an output return pathway. The esophageal heat transfer device is described with at least one lumen defining the fluid path and may include input ports and output ports for exchanging the heat transfer medium with an external heat exchanger interface.

Claims Coverage

The independent claims are directed to an integrated system that simultaneously delivers an electrical shock to a heart from within the esophagus and manages core body temperature using a non-inflatable esophageal heat transfer device with a heat transfer medium fluid path, with electrode coupling and external reservoir support. Across the independent claims, the inventive coverage includes 6 inventive features.

The independent claims collectively cover an esophageal system that uses a non-inflatable heat transfer region and a heat transfer medium fluid path to manage core body temperature while an electrode coupled to the non-inflatable heat transfer region is positioned within the esophagus proximate to the heart to deliver an electrical shock simultaneously. The claims further require electrode lead wire coupling for shock delivery and an external reservoir for storing the heat transfer medium.
