PRODUCT BRIEFS: FDA okays 1/3-size cochlear implant
From BBI Newsletter, The, 8/1/98

A cochlear implant/processor combination to improve the hearing of severe to profoundly deaf adults, and profoundly deaf children who are very young, has been approved for commercialization by the FDA. The Nucleus 24 Channel Cochlear Implant, produced by Cochlear Corp. (Denver, Colorado), is an implant/processor combination one-third the size of other implants, enabling implantation in children as young as 18 months. Cochlear characterized the device as the "first true advance in cochlear implant technology in more than a decade, and one that com-bines the most sophisticated technology with the sim-plest, most cosmetically discreet external device avail-able." The implant is used in conjunction with the company's multi-channel ESPrit Ear Level Speech processor, about the size of a hearing aid worn behind the ear, and weighing less than half an ounce. Besides its small size, the Nucleus 24 offers a maximum num-ber of stimulation electrodes to enhance the user's chance of hearing sounds and interpreting speech. Cochlear estimates the potential market for the device to be about 200,000 adults and children cate-gorized as profoundly deaf. The cost of the devices and the implanting procedure will range from $30,000 to $50,000, according to a spokesperson for the com-pany. The Nucleus 24 takes cochlear implant technol-ogy "into the next century," said President and CEO Ronald West. "By optimizing the capabilities of the internal device and miniaturizing the external speech processor without sacrificing performance, we have developed the ultimate cochlear implant system. In doing this, we have expanded our base of potential candidates for the device, to those cochlear implant candidates who have delayed their decision due to their aversion to wearing the body-worn speech processor. Now, wearing a cochlear implant is as sim-ple as wearing a hearing aid." West noted also the particular advantages for those who receive the device at an early age. "We know from years of research that the earlier children are implanted, the more likely they are to develop speech and hearing at a rate more like that of their hearing peers," he said. Results of clinical trials have shown that the implanted device and processor pro-vide increased confidence "in school, sports, work and social situations," according to Noel Cohen, MD, professor and chairman of the Department of Oto-laryngology, New York University Medical Center (New York), one of the more than 30 medical centers that conducted product trials. The device has been approved outside the U.S. for more than a year and has been implanted in more than 2,000 individuals. The company is hoping to gain regulatory approval for the device in Japan sometime in 1998. Elsewhere in the product pipeline: * ArthroCare (Sunnyvale, California) has intro-duced three new wands expanding the company's line of instruments for removing or shrinking tissue during arthroscopic joint surgery. The CoVac wand adds suction to the existing functions of tissue removal and hemostasis, reducing loose or free-float-ing tissue. The Saber features a single, curved elec-trode that removes tissue along the full length of the electrode, not just at the tip. And the Eliminator has a broad, brush-like design and larger electrode surface for rapid tissue removal and enhanced coagulation. * Biolase (San Clemente, California) has received FDA 510(k) clearance to begin marketing of the Skin-Laser System, recently acquired from Laser Skin Toner (St. Louis, Missouri) in a stock deal. The Skin-Laser focuses laser energy to the underlayer of dermis to create skin tightening without significant damage, burning, or surface cuts. The system will become part of Biolase's Aesthetic Division, which includes the company's DermaLase, HydroKinetic System and Lazer ToothBrush products. * Bio-Plexus (Vernon, Connecticut) has received a patent for its Drop-It needle holder, designed for one-handed disposal of blood-collection needles by health care workers. It features push-button quick release and can be used with up to 100 Punctur-Guard or conventional needles.

Cardiac Science is the developer of the Powerheart Automat-ic External Cardioverter Defibrillator technology, a bedside defibrillator used to monitor hospitalized cardiac patients for life-threatening heart rhythms, delivering defibrillation shock without human inter-vention should a patient suffer cardiac arrest. * Cardima (Fremont, California) has received FDA approval for its Vueport balloon occlusion guid-ing catheter, a balloon catheter with a compliant bal-loon on its distal tip designed to allow access and enhance visualization of the coronary venous system for mapping of ventricular tachycardia. The device is designed to temporarily occlude the coronary sinus, which is the main draining blood vessel in the heart, allowing the physician to inject radiopaque dye which shows the vasculature of the heart during X-ray. Additionally, the company received 510(k) clear-ance for its minimally invasive Pathfinder Mini microcatheter for diagnosing ventricular tachycardia, a condition affecting an estimated 1 million people in the U.S. and the most common causes of sudden car-diac death. The device is the smallest available micro-catheter for VT diagnosis, thereby enabling the physi-cian to access areas of the heart currently inaccessible by traditional catheter technology. It is the size of a coronary guide wire and uses Cardima's technology to diagnose signals from within the heart wall rather than from within the heart chambers. * Computer Motion (Santa Barbara, California), a developer of robotic and computerized surgical sys-tems, has received FDA approval to market its voice-controlled laparoscopic insufflator, a device used to create operating space necessary to perform minimal-ly invasive surgery. The insufflator is the sixth voice-controlled device designed to work with the compa-ny's Hermes OR Control Center. * CryoLife (Marietta, Georgia) has been awarded the European CE mark for its CryoLife-Ross porcine heart valves, allowing unrestricted distribution in European markets. The valve is designed for use in car-diac reconstruction surgeries in children. The product line features a series of heart valve replacements appropriate to various stages in the growth cycle of infants and young children as they mature and out-grow implanted valves, thereby fulfilling a critical shortage in infant tissue heart valves. The product augments the company's CryoLife-O'Brien porcine valve line and the CE mark for both valves will be used to support FDA applications for approval. * Endocare (Irvine, California) has received FDA approval of its investigational device exemption appli-cation to initiate human clinical studies of the Horizon Temporary Stent for the relief of acute urinary reten-tion. The device provides temporary relief of bladder outlet obstructions in those suffering benign prostatic hyperplasia. Made of nitinol, the device features shape memory designed for quick and easy introduction and removal through a minimally invasive procedure. After placement, the device expands to open the pro-static urethra, providing up to 30 days of relief. With the approval, multi-site clinical studies are scheduled to begin by the end of summer. * Equidyne Systems, a subsidiary of American Electromedics (San Diego, California), has received two U.S. patents for its Injex needle-free medication injection technology. The system delivers medication painlessly through the skin without a needle. The product delivers a wide variety of physician- and self-administered medications, including insulin, vac-cines, anesthetics, inoculates, protein-based recombi-nants and other drugs. The Injex system has received FDA 510(k) marketing clearance. * FemRx (Sunnyvale, California) has received FDA510(k) clearance from the FDA to market its Mae-stro Fluid Management System, which integrates with the Flo-State Fluid Management System to provide simplicity and control in managing minimally-inva-sive surgical procedures inside the uterus.
