Abstract
The invention describes fluid-based lead systems. The fluid-based leads may be used for sensing from, and stimulating of, human tissue. The fluid-based leads can be used to transfer signals between two locations. The fluid-based leads offer advantages when communicating signals along their length since the leads may be safely used in magnetic environments and offer increased elastic characteristics which are less prone to breakage. The leads can be used externally or with implantable devices, such as those used to monitor, and deliver therapy during the treatment of medical disorders such as cardiac and neurological disorders.
Claims24
A lead for communicating electrical signals, comprising:
- a. a sheath;
- b. an electroconductive proximal lead connector;
- c. an electroconductive distal lead connector;
- d. at least a first compartment and a second compartment positioned serially within the sheath, said compartments configured for operating jointly to provide electrical communication between the proximal and distal lead connector.
A lead for communicating electrical signals, comprising:
- a. a sheath;
- b. an electroconductive proximal lead connector;
- c. an electroconductive distal lead connector;
- e. a conductive mixture contained within said sheath for providing electrical communication between the proximal and distal lead connector and for approximately conforming to the shapes which the sheath can assume;
- and,
- f. at least one support structure for deterring unwanted deformation of the sheath from occurring.
An elastic and conductive lead bridge for elastically connecting a lead to a target, comprising:
- a. a flexible sheath;
- b. an electroconductive proximal lead connector for connection to a conventional wire-based lead;
- c. an electroconductive distal lead connector for connection to a target;
- d. a conductive mixture contained within said sheath for providing electrical communication between the proximal and distal lead connector, that approximately conforms to the shapes which the sheath can assume.
