This invention relates generally to the electrical treatment of malignant tumors and neoplasms by applying a voltage to affected tissue. Devices and various adaptations therein are described for use in electrical therapy. Additionally, various chemotherapeutic agent and radiation therapies are described which may be advantageously used in conjunction with electrical therapy to ameliorate cancer.

Method and device for treating abnormal tissue growth with electrical therapy

Methods and apparatus for treating fibrillation utilize biphasic waveforms. A cardiac stimulator includes a defibrillation circuit that uses a pulse width modulated capacitive discharge to generate various biphasic waveforms, one or more of which may be delivered to the heart to treat the fibrillation.

Methods and apparatus for treating fibrillation and creating defibrillation waveforms

A method for the electrical treatment of malignant tumors and neoplasms by applying a voltage to affected tissue. Devices and various adaptations therein are described for use in electrical therapy. Additionally, various chemotherapeutic agent and radiation therapies are described which may be advantageously used in conjunction with electrical therapy to ameliorate cancer.

Method and device for treating cancer with electrical therapy in conjunction with chemotherapeutic agents and radiation therapy

An implantable electrical method and apparatus for the treatment of cancer tumors based on the usage of various levels of electrical fields and current to assist in specific ways to reduce tumor size. The appropriate voltage, currents, and time duration as well as the usage of adjunctive pharmacological therapy are taught.

Implantable device and method for the electrical treatment of cancer

This present embodiment relates generally to the electrical treatment of malignant tumors and neoplasms by applying a voltage to affected tissue. Devices and various adaptations therein are described for use in electrical therapy. Additionally, various ambulatory devices are described which advantageously increase versatility of the electrical therapy system. The ambulatory devices may include an internal and external power source and/or a first and second power source. The ambulatory devices may also include communication means for communicating between various portions of the device.

Partially implantable system for the electrical treatment of abnormal tissue growth

A tubular sleeve is provided for enabling a physician to impart a preselected shape in an implantable tubular device, such as a cardiac lead, a catheter or some other tubular structure. The sleeve may be deformed by the surgeon before or at the time of implantation to customize the shape of the tubular device to the particular anatomical structures to be encountered by the device. To retain the deformation imparted by the physician, the sleeve may be composed of a heat-sensitive shape-memory material or an elastomeric material provided with a plastically deformable rib.

Apparatus for imparting physician-determined shapes to implantable tubular devices

A method and apparatus for evaluating heart rate variability of the heart of a person in order to forecast a cardiac event. A cardiac stimulator receives heart beat signals from the heart and determines a measurement of heart rate variability based on statistical data derived from the heart beat signals and sensing data derived from a sensor. This measurement of heart rate variability is compared with previously stored heart rate variability zones defining normal and abnormal heart rate variability. These zones are modifiable after the occurrence of a cardiac event. Once a cardiac event is detected, a pathway is computed which extends from a generally normal heart rate variability condition to an abnormal heart rate variability condition. Subsequent measurements of heart rate variability are compared with this pathway. Selective therapy regimes are initiated depending on the measurement of heart rate variability.

Implantable medical device responsive to heart rate variability analysis

A tubular sleeve is provided for enabling a physician to impart a preselected shape in an implantable tubular device, such as a cardiac lead, a catheter, or some other tubular structure. The sleeve may be deformed by the surgeon before or at the time of implantation to customize the shape of the tubular device to the particular anatomical structures to be encountered by the device. To retain the deformation imparted by the physician, the sleeve may be composed of a heat-sensitive shape-memory material or an elastomeric material provided with a plastically deformable rib.
