An implantable medical device for treating the back of a patient. Stimulation energy is delivered to muscles or joint capsules or ligaments or nerve fibers to improve the heath of the back.

Apparatus and method for stimulating neuromuscular tissue in the stomach. The neuromuscular stimulator stimulates the neuromuscular tissue by applying current-controlled electrical pulses. A voltage sensor detects the voltage across the neuromuscular tissue to determine if the voltage meets a predetermined voltage threshold. A control circuit adjusts the current-controlled pulse if the voltage is found to meet the voltage threshold, such that the voltage does not exceed the voltage threshold. A voltage-controlled pulse may also be applied to the tissue. A current sensor would then detect whether the current on the neuromuscular tissue meets a predetermined current threshold, and a control circuit adjusts the voltage-controlled pulse such that the current does not exceed the current threshold. A real time clock may be provided which supplies data corresponding to the time of day during the treatment period. A programmable calendar stores parameters of the stimulating pulse, wherein the parameters have a reference to the time of day.

Devices, systems, and methods are disclosed for relaying information from a cardiac pacemaker to an external device. Logic on the pacemaker modulates a heartbeat clock of the pacemaker to encode information onto a blood pressure sequence. This is accomplished by adding or subtracting a small subinterval to or from a pulse repetition interval of the pacemaker. A muscle stimulator beats the heart according to the modulated sequence. A monitoring device external to the body monitors the blood pressure to retrieve the encoded information, or message. The encoded information is then decoded to determine the information in the message. This information may concern the pacemaker as well as other devices within the body that are in communication with the pacemaker such as blood monitors, etc. Since the message is conveyed via simple modulation of the heart beat intervals, no separate transmitter is required in the pacemaker which would otherwise increase cost and decrease battery life.

A gait modulation system including: (a) a sensor device including a sensor adapted for associating with at least one lower limb of the patient, the sensor for transducing at least one parameter related to a gait of the patient, so as to obtain gait data related to the gait, and (b) a muscle stimulator including: (i) an electrical stimulation circuit, the circuit adapted to supply an electrical stimulation output to an electrode array for performing functional electrical stimulation of at least one muscle of the lower limb, and (ii) a microprocessor, operatively connected to the at least one sensor, the microprocessor adapted for: receiving a stream of gait information based on the gait data; processing the gait information, and controlling the stimulation output based on the processing of the gait information, and wherein the microprocessor is further adapted to identify a failure in the stream of gait information, and to consequently control the electrical stimulation circuit to deliver a fail-safe stimulation output over a portion of a duration of the failure.

A method and apparatus include a therapeutic or developmental apparel that includes hardware and / or software for stimulating a muscle. Such apparel may comprise, for instance, of: a glove, a uniform, a shoe, a sock, a vest, a sleeve, a shirt, a hat, a helmet, a brace, a suspender, eye wear, a pad, jewelry, a watch and pants. A muscle of a user may be stimulated by the garment as the user moves, such as a when a golfer practices her swing. Combining such muscle stimulation with the act of practicing the movement of the swing has a synergistic effect of training the muscle as it builds strength. Similarly, a partial paralytic may regain strength in their hand by wearing a vest or other garment configured to transcutaneously deliver a stimulating signal. Where desired, the garment may include at least one electrode configured to deliver a stimulating signal to the wearer. In another or the same embodiment, wired electrodes may extend from the garment or an adjacent signal generator to the wearer. This configuration may allow other, targeted muscles to be concurrently stimulated while the user wears the garment.

The invention discloses a low-power-consumption implantation type medical system and a method for lowering the operation power consumption of the medical system and belongs to the field of miniature medical instruments. An in-vivo implantation device of the implantation type medical system has at least three kinds of states which include the dormancy working state, the interception working state and the awakening working state. The system is formed by connecting the in-vivo implantation device and an in-vitro control device in a wireless communication mode, the in-vivo implantation device is in the dormancy working state once powered on, and a first wireless communication module in the dormancy working state is always in an off state; when a doctor needs program control, the state is manually switched through an in-vitro control magnet, so that the in-vivo implantation device enters in the interception working state, and normal communication is performed between the in-vivo implantation device and the in-vitro control device. Extra power consumption is greatly lowered because program control is not needed in most of time, the service life of the product is prolonged, extensive use is achieved, and the low-power-consumption implantation type medical system can be used for an implantation type cardiac pacemaker, a defibrillator, a nerve stimulator, a muscle stimulator, an electrocardiogram recorder, a medicine pump and others and has extremely high economic benefits and social benefits.

The invention discloses a deep muscle stimulator which comprises a housing and impact heads.
