摘要:
Described herein are a method and apparatus for introducing instrumentation into the lymphatic system that can be used for physiological monitoring and/or delivery of therapy. Such instrumentation, for example, may include one or more sensors for measuring physiological variables and/or one or more instruments for delivering therapy that is adapted to be disposed within a lymphatic vessel.

Renal function may be modulated by an implantable device having one or more leads or catheters disposed near the kidney via the lymphatic system. In one embodiment, lymphatic drainage from the kidney is modulated to increase or decrease tubular reabsorption of salt and water. The renal function modulation therapy may be delivered in an open-loop or closed-loop fashion, with the latter dependent upon a physiological variable such as blood pressure or cardiac output.

摘要:
A technique utilizing an endolymphatically implanted lead having one or more electrodes that may be used for sensing cardiac activity and/or delivering cardiac electrical stimulation by an implantable cardiac device. An electrode disposed in the thoracic duct is in close proximity to the left ventricle and generates an electrogram especially suitable for ischemia detection and/or discriminating between ventricular tachycardias and supraventricular tachycardias.

摘要:
A device and method for controllably augmenting the flow of lymphatic fluid through one or more lymphatic vessels. The device may utilize various means of modulating the flow of lymph, including neural, mechanical and/or chemical stimulation and could be a stand-alone device or be incorporated into any cardiac, neuromodulation and/or drug delivery device.
摘要:
A respiratory monitoring system includes an implantable lymphatic sensor configured to be placed in a lymphatic vessel, such as the thoracic duct or a vessel branching from the thoracic duct, near the diaphragm. The implantable lymphatic sensor senses a signal indicative of respiratory activities. Examples of the signal include a diaphragmatic activity signal indicative of movement of the diaphragm and a transthoracic impedance signal indicative of pulmonary volume. In one embodiment, the respiratory monitoring system is incorporated into a cardiac rhythm management system that controls cardiac therapy delivery using the signal sensed by the implantable lymphatic sensor.
