An upper limb prosthetic device may comprise a hybrid-drive prosthetic device that includes one or more actuators fixed to a first arm portion and one or more cables extending from the one or more actuators along one or more cable paths defined through the first arm portion and a second arm portion to a terminal device/device assembly, where the one or more cables are configured to be actuated by the one or more actuators and are further configured to be actuated by pivoting the second arm portion toward the first arm portion, Alternatively, or additionally, the upper limb prosthetic device may comprise a modular prosthetic device that includes a modular terminal device assembly with removably coupled first, second, and third modular links configured to control the respective yaw, pitch, and roll of an end effector (e.g a prosthetic hand, a tool, an instrument or any other attachment).

An intravascular device for placement within an animal vessel, the intravascular device being adapted to at least one of sense and stimulate activity of neural tissue located outside the vessel proximate the intravascular device.

The invention relates to an automated hand, such as a prosthetic hand. In one form, the automated hand may be fluid compatible. In one form, the automated hand may comprise features to reduce the risk of harm to motors and/or other sensitive components of the hand when subject to an impact. In one form, the hand may comprise a wrist joint configured to allow the hand to curl and flex and/or to rotate. In one form, one or more digits of the hand may be individually controlled. In one form the hand may include a thumb rotation locking mechanism. In one form the hand may be provided with removable grip plates. In one form, the hand may be configured for use as a training hand.

An elbow joint rehabilitation system and an elbow joint rehabilitation method are provided. The elbow joint rehabilitation system includes a support member, a motor, a torque sensing unit, a first electromyography sensor, a second electromyography sensor and a motor control device. In the elbow joint rehabilitation method, the support member is configured to support an arm of a patient. Thereafter, the torque sensing unit is configured to sense the torque applied on the support member to obtain a sensed arm torque signal. Then, the first electromyography sensor and the second electromyography sensor are configured to sense the muscle activities of biceps and triceps of the patient to obtain electromyography signals. Thereafter, the motor is controlled to drive the support member to perform rehabilitation in accordance with the sensed arm torque signal, the electromyography signals and a current support member position provided by the motor.

Systems and methods for a wearable sensor system including a compressible material, a two-dimensional array of distance sensors, a support structure, and a controller. The compressible material is positionable relative to a tissue surface and the two-dimensional array of distance sensors is configured relative to the compressible material to detect compressive deformations of the compressible material. The support structure is configured to hold the compressible material in place relative to the tissue surface such that muscle movements at the tissue surface cause the compressive deformations of the compressible material and is also configured to restrict movement of the two-dimensional array during the muscle movements. The controller is configured to receive a signal from the two-dimensional array indicative of the compressive deformation of the compressive material at a location of each distance sensor

Various examples are provided for modular prosthetic devices and their use. In one example, a device includes a chassis assembly including a joint portion; and an interchangeable module that can be removably attached to the chassis assembly. The interchangeable modules can be configured for use in a wide variety of applications. The interchangeable modules can be quickly exchanged for different activities.

Features for a prosthetic wrist and associated methods are described. The wrist couples with a prosthetic socket and a prosthetic hand. The wrist may rotate the hand. The wrist includes features to prevent or mitigate undesirable separation of the wrist from the socket. The wrist may have an expanding coupling, such as an expanding ring, to better secure the wrist with the socket. An actuator may cause the coupling to expand outward to prevent or mitigate undesirable separation of the wrist from the socket. Alternatively or in addition, the wrist may include torque control features to prevent undesirable or premature separation of the hand from the wrist, for example when using a “quick wrist disconnect” (QWD) apparatus. A torque control method may tailor or limit multiple torques to be applied by the wrist to the hand based on operational requirements and phases, such as anticipated torque loads and operational timing.
