    摘要： The intrastromal corneal ring is adjustable in thickness and has an elongated, flexible, preferably transparent or translucent body which forms a circle. The intrastromal corneal ring is of a size such that it can be inserted into a human eye and is comprised of a material which is compatible with human ocular tissue. The thickness of the ring can be adjusted so that it is not necessary to stock a plurality of different rings of different sizes to be used in connection with a method of adjusting the shape of the cornea of the eye. A plurality of different embodiments of intrastromal corneal rings, including a spiral shaped intrastromal corneal ring, are disclosed each of which are adjustable in terms of their thickness. The thickness may be adjusted prior to the insertion of the intrastromal corneal ring into the cornea and may not be further adjustable after insertion. However, in accordance with preferred embodiments the intrastromal corneal ring is inserted at a thickness which is believed to be proper and may thereafter be further adjusted in order to precisely define the desired thickness and thereby more precisely adjust the shape of the cornea and focus the light entering the eye on the retina.

    摘要： Described herein are adjustable whole-nose nasal devices having a first passageway for communication with a first nasal passage and a second passageway for communication with a second nasal passage, an airflow resistor that inhibits expiration more than inspiration, and an adjustable connector. The adjustable connector may include one or more adjustable joints or regions that allow the whole-nose device to conform to the spacing between a subject's nostrils, and/or the orientation and angle of the subject's nostrils. Also described herein are whole-nose devices having a single airflow resistor communicating with both of a subject's nasal passages. Methods of treating a disorder using the whole-nose nasal devices are also described.

    摘要： This relates to restoring recoil or maintaining compression of an emphysematous or otherwise unhealthy lung and includes elastic members which contract or compress the lung tissue. The elastic member is secured to tissue of the lung either inside or outside of the lung to supplement the natural elasticity of the lung or maintain the tissue in a compressed state. The elastic member may include elastic patches, elastic bands, coil springs, covers or a combination of these elements.

    摘要： A disposable seal assembly for use with a reusable cannula, where the seal assembly is designed for use with the cannula during a single medical procedure and the cannula is designed for multiple uses (each time with a different seal assembly) during a number of medical procedures. The seal assembly includes both a flapper valve fluid seal (for sealing the cannula when no medical instrument is inserted through the seal assembly) and at least one instrument seal (for sealing the cannula when a medical instrument is inserted through the seal assembly). Preferably, the seal assembly has a body with a flange which can be snapped onto the cannula before use, and readily removed after use. Also preferably, the flapper valve has an over-centered hinge. In other embodiments, the invention is a seal assembly which includes at least one double instrument seal including a sacrificial flange and a sealing flange, and optionally also a flapper valve. The sealing flange seals the cannula when a medical instrument is inserted through the seal assembly even when the sacrificial flange has been cut during insertion of the instrument. In other embodiments, the invention is a system including a reusable cannula, and a disposable seal assembly of any of the described types which can be snapped onto the cannula before use and readily removed after use.
