Abstract:
An active compression/decompression CPR device (10) includes two pressure members (18, 20) mounted on a common beam (12). When placed on the victim with one member (18) on the chest and the other (20) on the abdomen, pressure on one end (34) of the beam (12) causes compression of the thorax and decompression of the abdomen. Conversely, when pressure is applied to the other end (36) of the beam (12), the abdomen is compressed and the thorax is decompressed.
Abstract:
A pneumatic compressor (10) supplies both positive and negative pressure for operating a medical device (300). The pulsing sounds generated by the compressor are attenuated by connecting the inlet (224) of the positive pressure side (34) of the compressor and the outlet (124) of the negative pressure side (32) of the compressor to a common resonating chamber (30). A port (400) in the resonating chamber acts as an outlet for the discharge of excess air in the chamber and an inlet for the entry of make-up air. By adjusting the diameter of the port with respect to the volume of the resonating chamber, sound attenuation can be optimized. In a compact design, the compressor housing serves as the resonating chamber.
Abstract:
An active compression/decompression CPR device capable of providing both complete cardiopulmonary support and cardiopulmonary assistance includes two or more thoracic compressors, preferably inflatable bladders, positioned so that the chest can first be flattened and compressed, increasing the pressure in the chest, and then circularized and decompressed, decreasing the pressure in the chest. When inflatable bladders are used, they can be surrounded with a rigidifying vest which resists outward bladder expansion. Compression and decompression can be performed along with abdominal compression, and the device is capable of shifting between support and assist modes when the patient's condition so requires.
Abstract:
An insertion guide wire (10) with an anchor (24) formed in the distal end (22) for precisely locating a subcutaneous arterial wound and guiding a plug of hemostatic material (68) thereto. When the hemostatic material is properly placed, the anchor can be released and the guide wire removed, leaving no foreign object in the lumen (42) of the artery (44).
Abstract:
Injectable implant compositions for soft tissue augmentation comprise elastin and collagen and a biocompatible carrier. An injectable implant composition for soft tissue augmentation is derived from the ligamentum nuchae which has been treated to remove non-collagenous and non-elastinous proteins. Methods of making an injectable implant composition for soft tissue augmentation from the ligamentum nuchae are described.
Abstract:
Soft tissue implants (10) can be constructed by forming an outer membrane into a closed pouch (14) and filling material (16) in that pouch (14). A composition for use as a filler material (16) in such a soft tissue implant (10) may include elastin and collagen. The filling material (16) has collagen as a component thereof, and this collagen can be cross-linked. Methods of making such implants are described.
