An assistance method for assisting a person in grasping or otherwise manipulating an object includes receiving video of a hand of the person and of an object. An intent to grasp the object is identified based on proximity of the hand to the object in the video or as measured by a proximity sensor, or using gaze tracking, or based on measured neural activity of the person. The object and the hand in the video are analyzed to determine an object grasping action for grasping or otherwise manipulating the object. An actuator is controlled to cause the hand to perform the determined hand action for grasping or otherwise manipulating the object.

According to an aspect, an implant includes a sheath defining a lumen, a cable member disposed within the lumen defined by the sheath, and a tensioner. The tensioner is configured to engage the cable to apply tension to the sheath.

An antibiotic delivery system including an intramedullary stem that is adapted to be removably mounted into a medullary canal of a bone. The stem includes a body having an inlet adapted to be in fluid communication with a source of liquid-borne antibiotic and a plurality of outlets disposed along the stem. A channel extends between the inlet and the plurality of outlets for delivering a fluid-borne antibiotic from the inlet to the plurality of outlets so as to distribute the antibiotic along the medullary canal in a controlled fashion. A method of treating an infected joint during a two-stage re-implantation of an orthopedic implant is also disclosed.

A conductive human interface has a fabric layer with an interior surface and an exterior surface. A soft coating overlies the interior surface of the fabric layer. An electrode or sensor is included to connect with a residual limb. A conductive path connects the electrode or sensor with an electrical connector which, in turn connects with a prosthetic or other assistive device. The conductive path includes a conductor having a section overlying the fabric layer. The overlying section of the conductor can be cord of conductive thread. A nonconductive support thread can extend through the fabric layer from the exterior surface to the interior surface, and further around the conductor to secure the overlying section of the conductor to the fabric layer.

Provided herein are cranial implant devices that include at least one acoustic, optical, and/or photoacoustic lens element comprising one or more electromagnetically translucent, electromagnetically transparent, sonolucent, and/or acoustically active materials. The cranial implant devices are structured for subgaleal scalp implantation within, beneath, and/or over at least one cranial opening of a subject and typically includes a substantially anatomically-compatible shape. In addition, the cranial implant devices permit transcranial therapeutic ultrasound, transcranial diagnostic ultrasound, photoacoustic imaging, electromagnetic wave diagnostic imaging, and/or electromagnetic wave therapeutic intervention of intracranial matter of the subject via the acoustic, optical, and/or photoacoustic lens element when the cranial implant device is subgalealy implanted within, beneath, and/or over the cranial opening of the subject. Other aspects are directed to various related systems and methods of obtaining diagnostic information from, and/or administering therapy to, a subject.

An implantable medical device for use as an artificial urinary bladder can include a collection container configured to be placed in a patient's abdominal cavity and a pump configured to be subcutaneously placed outside the abdominal cavity to allow the patient to perceive the need for urination and controls timing of the urination. Flexible tubing can connect the patient's ureters to the collection container, connect the collection container to the pump, and connect the pump to the patient's urethra, with unidirectional valves where needed, to allow for urination through the patient's natural urethra. The implantable medical device can optionally include a cleaning port and tubing connecting the cleaning port to the collection container for introducing a liquid cleaning agent into internal urination circuit of the device for cleaning, disinfection, and prevention of stone formation.

An intraocular lens system for implantation in an eye is provided. The intraocular lens system includes a ciliary body implant having a passive ciliary signal element, the ciliary body implant being implantable in the eye such that the ciliary signal element provides a ciliary signal in response to a movement of the ciliary muscle of the eye. The intraocular lens system also includes an intraocular lens having a sensor element for receiving the ciliary signal. The ciliary body implant and the intraocular lens are formed separately from each other and the intraocular system is configured to control a refractive effect of the intraocular lens that is dependent on the ciliary signal received from the sensor element.

A tunable implant, system, and method enables a tunable implant to be adjusted within a patient. The tunable implant includes a securing mechanism to secure the implant in the patient, a actuation portion that enables the implant to move and an adjustment portion that permits adjustment of the implant after the implant has been positioned within the patient. The method of adjusting the tunable implant includes analyzing the operation of the implant, determining if any adjustments are necessary and adjusting the implant to improve implant performance. The implant system includes both the tunable implant and a telemetric system that is operable to telemetrically receive data from the tunable implant where the data is used to determine if adjustment of the tunable implant is necessary. The system also includes an instrument assembly that is used for performing spinal surgery where the instrument assembly includes a mounting platform and a jig.
