General Hospital Devices and Therapeutic Products
Acapella chest physical therapy device
Device combines benefits of positive-pressure therapy and airway vibrations
Designed to mobilize pulmonary secretions, the Acapella chest physical therapy (CPT) device is intended for patients with lung disease and associated secretory problems. It is easier to tolerate and is less time-consuming than other CPT systems and facilitates the opening of airways. The vibratory positive-pressure (PEP) therapy system functions independently of gravity controls and meets the needs of patients with low-pressure and low-flow constraints. The device can be used with a standard mouthpiece, a mask, or a TheraPEP pressure port and gauge for precise measurements. It contains a one-way inspiratory valve that allows inhalation and exhalation without removing the product from the patient's mouth.

Implant and Tissue-Replacement Products
Ancure endograft system
Abdominal aortic aneurysm treatment is less traumatic
The Ancure surgical procedure uses a catheter to insert a sheath through the femoral artery in the leg, a less-invasive procedure that causes fewer traumas than traditional surgical techniques. The device's graft implant passes through a 5-mm aperture and is then positioned, deployed, and fastened remotely. The delivery technique involves removing the implant jacket, exposing the ipsilateral attachment system, using pull rings to release the implant, controlling its movement, and sealing it. Numbered safety tabs prevent out-of-sequence deployment. Stirling Design, Aptos, CA; Guidant Corp., Indianapolis.
Helex septal occluder
Prosthesis minimizes invasive closure of atrial septal defects
A permanently implanted prosthesis is composed of an implantable occluder that is premounted on a 9-F delivery system and a preshaped delivery catheter for access to atrial septal defects that eliminates the need for a long intruder sheath. Within the 9-F delivery catheter is a control catheter, which pushes the device during delivery, and an integral retrieval cord that allows device withdrawal during loading and retrieval. Both catheters are supplied with radiopaque markers at their distal tips for fluoroscopic visualization during device deployment. A cardiologist can reposition or remove a malfunctioning device without compromising patient safety. W. L. Gore and Associates, Flagstaff, AZ.
Nucleus 24 Contour cochlear implant
Implant benefits those with severe to profound hearing loss
The Nucleus 24 Contour is an implant with a permidiolar electrode array that safely places stimulating electrodes adjacent to the modiolar wall of the cochlear without the use of invasive bands or positioners. The implant operates by receiving sound through a speech processor, then transforming it into electrical impulses that are transferred through the electrode array to stimulate the ganglion nerve cells in the modiolus. To achieve optimal access to the auditory nerve, a conical cavity is drilled in the temporal bone with a tiny entrance that can accommodate insertion of the implant. Cochlear Ltd., Sydney, Australia.
In Vitro Diagnostics
Benchmark automated histology staining system
Automated system stains tissue samples on glass microscope slides
The Benchmark automates the labor-intensive steps required in baking, dewaxing, cell conditioning, and staining tissue for cancer and infectious disease diagnosis. The slides are processed with various reagents that remove embedded paraffin, pretreat tissue to expose targets, and bind and detect specific antigens or DNA and RNA sequences with localized color change or fluorescence. The system can control slide temperature and evaporation, minimize solvent exposure, control multiple instruments through a single user interface, and read patient sample and reagent bar codes. Ventana Medical Systems Inc., Tucson, AZ.
EScreen drugs-of-abuse testing system
A networked point-of-care system designed for drug testing
The eScreen includes eCup, a specimen cup with a smart lid, and an optical Internet appliance that scans, reads, and writes drugs-of-abuse test assay results and sends the results confidentially via a secure Internet connection. The fluid sample is transferred from the cup to the test chambers by means of a plunger that acts directly on a portion of the urine sample to force it between a double-walled stem to the lid and then distribute it into three test chambers. eScreen Inc., Los Angeles.
TravelMate female urinary device
A noninvasive female urinary device reduces need to self-catheterize prior to travel
TravelMate is an alternative to female urinals and traditional urinary catheters that is noninvasive and reduces the risk of urinary tract infection. It consists of a piece of polyethylene that conforms to shape variations in the area surrounding the urethral orifice. It creates a comfortable leak-free seal between the device and the body but is small enough to be easily positioned even while sitting in a wheelchair or standing.

Radiological and Electromechanical Devices
Beta-Cath interventional cardiology device
Prevents or treats restenosis following balloon angioplasty
To prevent vessel closure, the Beta-Cath delivers a prescribed dose of beta radiation to the coronary artery vessel wall from inside the coronary artery via a catheter-delivery system. The transfer device stores, shields, and delivers beta radiation through individual sealed sources that travel to the artery, then return to the device via a fluid-hydraulic delivery method. A small multilumen single-use delivery catheter allows radiation to reach the treatment site while preventing it from touching body tissues. Novoste Corp., Norcross, GA; Innovation Factory, Norcross, GA.
DirectView CR800 system
System facilitates wide electronic x-ray distribution
A radiographic digital image capture and processing system utilizes exam-room exposure sources and cassette-based techniques to create electronic records of patients' images for future reference. Typical imaging applications include chest x-rays, bone x-rays, and soft tissue images. The DirectView CR800 has a remote operations panel that allows multiple units to be placed throughout the imaging environment to improve workflow and patient care. Eastman Kodak Co., Rochester, NY.

Needle shafts are visible under ultrasound imaging
Ultrasound needles are coated to render the shaft visible with ultrasound imaging, enabling the devices to be used under ultrasound guidance during aspirations, biopsies, localizations, and amniocentesis procedures. Echo-Coat ultrasound coating is a layered polyurethane system when applied to 304-stainless-steel needles, the porous microstructure entraps tiny bubbles of air to enhance the echogenicity regardless of the needle angle relative to the ultrasound beam. STS Biopolymers Inc., Henrietta, NY.
Rehabilitation and Assistive-Technology Products
Claro and WatchPilot digital hearing instruments
Digital hearing aid system is remote controlled
uses two microphones to create digital response and digital perception processing
to emulate normal human hearing. An AudioZoom function
creates a directional response, allowing the user to increase sound levels of speech while decreasing background noise. The digital perception processing uses 20 overlapping and interdependent channels to process sound like the normal ear. A fine-scale noise canceller scans channel signals and identifies and increases speech signals and reduces other noises. Phonak, Warrenville, IL.
Helios personal oxygen system
High-efficiency liquid oxygen system designed for ambulatory use
A portable oxygen system consists of a 46-L reservoir and a pneumatic 4:1 conserver device, which allow for a good combination of duration and small size. The unit weighs 3.4 lb when full. The double-walled oxygen bottles have multilayered, glass paper and aluminum foil insulation contained in a vacuum to reduce heat transfer and cryogenic evaporative losses. The volume of oxygen supplied to the user is delivered in a pulse at the beginning of patient inspiration to maximize efficacy.

Applications include endoscopy, radiological procedures, and urologic, gynecologic, and cardiac interventions. LSI Solutions, Rochester, NY.
Mammotome handheld breast biopsy system
Multiple biopsy samples are collected with a single needle insertion
The Mammotone system is a minimally invasive, highly accurate mobile instrument for helping doctors diagnose breast cancer at the earliest stages. The probe is inserted once into the patient's breast via a small incision. Once inserted and positioned via ultrasonic imaging, it uses vacuum aspiration and an internal rotating cutter to collect multiple samples up to eight times the weight of those obtained using traditional spring-loaded biopsy equipment. A metal tissue marker can be deployed through the probe into the sampled biopsy making it easier to locate the lesion site for postprocedure mammographic diagnosis.
