1 14 January 2010 Today s implantable stimulator market and prospective Worldwide, more than 500,000 permanent cardiac pacemakers are implanted each year. As the population ages and as indications for pacemakers expand, the number of implants continues to increase. Approximately 100,000 people worldwide have received cochlear implants, with recipients split almost evenly between children and adults. The vast majority are in developed countries due to the high cost of the device, surgery and post-implantation therapy. A small percentage of CI-recipients have bilateral implants, or one CI in each cochlea. Bilateral cochlear implants are a growing trend globally. Statistics for all other devices, are not available at this time, but there are many patients who received neuromuscular prostheses for DBS (Parkinson, epilepsy, depression, etc), artificial retina, respiration, motor (standing up, walking, foot drop), etc Overview Auditory system: Cochlear implant Visual system: Visual stimulator (visual prosthesis: cortical, retinal, etc) Central nervous system: Stimulators (DBS, Parkinson, epilepsy), multichannel sensors, closed loop prosthesis Vagus / Vacal nerve: Control and sensing inside the body Peripheral nervous systems: Various neuromuscular stimulators (bladder, bowl, foot drop, pain, paralysis, etc..) Cardiovascular system: Cardiac pacemaker, defibrillator, ECG sensors Gastrointestinal system: Ingestible sensors and stimulators Respiratory system: EMG and pressure sensors Movement disorders: Functional electrical stimulation. 1
2 Cochlear implants The first and, so far, most successful brain-machine interfaces (BMI) It is estimated that 27 million Americans have a significant hearing loss About 1 million have a severe to profound loss that would qualify for a CI, but only 20,000 Americans have CI (2004) About 45,000 children are eligible but only 9,000 have CIs Worldwide, over 100,000 patients from age 1 to 80 years old have received implants (2005) Miss America of 1995, Heather Whitestone, deaf since infancy received an implant in Cost of CI ~$60,000 each; Medicare can pay around $20K; some insurance companies may pay the rest, others will not Surprisingly, perhaps, the most resistance to implants comes from the deaf community. Advanced Bionics (Harmony) Cochlear implants Power and size reduction by minimizing digital stages. Aim was to offer improved aesthetics, reduction of practical limitations and improved perception. Advanced signal processing and circuit techniques. Integrated circuit for a cochlear implant, by Georgiou & Toumazou Cochlear implants: spectral resolution (number of channels) The limited number of channels affects pitch perception It is not possible to say for sure what a cochlear implant sounds like, and it differs from person to person. Number of channels (flexibility) play important role. Auria Processor - Advanced Bionics 2
3 Retinal implant Blindness due to light-sensing cell malfunction is addressed by retinal implants. The retinal prosthesis is designed to take over the function of the lost photoreceptors by electrically stimulating the remaining healthy cells of the retina. A retinal prosthesis can be placed either on the inner retinal surface ("epi-retinal") or below the retina in the area of damaged photoreceptors ("sub-retinal") to try to stimulate the remaining viable retinal cells. Electrical stimulation of the retinal cells evokes the sensation of discrete points of light (referred to as phosphenes"). Weiland & Humayun, A biomimetic retinal stimulating array, EMB. Mag., Cortical stimulator: Visual prosthesis The cortical approach incorporates a microelectrode array, which is placed either intracortically or on the cortical surface. By stimulating the visual cortex directly, this approach bypasses the retina and optic nerve. The Utah silicon micromachined microelectrode array. It has a large number of 1.5mm long electrodes that project out from a very thin (0.2 mm) substrate and that are separated from each other by 0.4 mm.

A brain pacemaker is implanted to electrically stimulate specific region of the brain. DBS in select brain regions has provided remarkable therapeutic benefits for otherwise treatment-resistant disorders. Several types of electrode arrays Thin electrode rods Subdural electrode grid.

6 Approaches to vagus nerve stimulation It is the only nerve that starts in the brainstem and extends down below the head, to the neck, chest and abdomen, where it contributes to the innervation of the viscera. Besides output to the various organs in the body, the VN conveys sensory information about the state of the body's organs to the central nervous system. Implantable stimulator Helix cuff interface VNS periodic, or manual Not yet fully understood how VNS works Battery needs changing after 6 years Partially successful and potential for improvement. Implantable cardiac pacemakers and defibrillators A pacemaker is used to treat bradycardia (the heart beats too slowly) or arrhythmias (abnormal cardicac rhythms). Types of pacemakers: Single-Chambered Pacemakers: Use only one lead placed into the right upper chamber of the heart (right atrium) or the right lower chamber (right ventricle). Dual-Chambered Pacemakers: Use two leads. One is placed in the right atrium, the other in the right ventricle. Cardiac Resynchronization Therapy : Use three leads. One is in the right atrium, one is in the right ventricle, and one is placed through the heart s veins to left ventricle. Rate-Responsive Pacemakers: can be programmed to increase or decrease heart rate to match patient s activities (i.e. resting or walking). Current State-of-the-Art of the Single and Dual Chamber Pacemaker. Medtronic, Lead IPG Anode ICs/Die Stack Cathode Feedthrough Battery Activity Sensor Spinal cord stimulation Chronic pain in back & legs Neurostimulators work by sending mild electrical impulses to the epidural space near the spine. These impulses replace pain with a tingling sensation (must be above the level of pain). For Complex Regional Pain Syndrome, a chronic pain condition that most often affects the arms, legs, hands, or feet. This condition is also known as reflex sympathetic dystrophy or causalgia. 6
7 Gastrointestinal remote sensor A microelectronic pill for in situ studies of the gastrointestinal tract. Combines microsensors and integrated circuits with system-level integration technology. The measurement parameters include real-time remote recording of temperature, ph, conductivity, and dissolved oxygen. The unit comprises an outer biocompatible capsule encasing four microsensors, a control chip, a discrete component radio transmitter, and two silver oxide battery cells. Photograph of the 4.75 x 4.75 mm ASIC control chip used in the pill. The prototype is 16 x 55 mm. Johannessen et al. Implementation of Multichannel Sensors for, IEEE TBME, V51, Gastrointestinal implantable devices Gastric Electrical Stimulation for Gastroparesis Gastroparesis is a stomach disorder in which food is digested more slowly than normal. With gastroparesis, the stomach muscles work poorly (or not at all), thus preventing the stomach from emptying properly. The Enterra neurostimulator from Medtronic received humanitarian device exemption (HDE) approval from the FDA in Humanitarian Device: The effectiveness of this device for this use has not been demonstrated. Chemical sensors Chemical sensors are used for identification and quantification. They need to be both selective and sensitive to a desired target species in a mixture of chemical species.
