摘要:
Tissue securement fibers of reduced cross sectional area and methods of making them are disclosed. The fibers comprising reduced cross sectional areas provide higher degrees of flexibility by providing discrete bending zones most useful in applications when the fiber is bent at an included angle less than 180°, more particularly when the included angle is less than 90°.

An implant for treating obstructive sleep apnea includes a first chamber containing an incompressible fluid, a second chamber containing a compressible fluid, and a flexible diaphragm separating the first and second chambers. The incompressible fluid is in communication with the compressible fluid via the flexible diaphragm. The first chamber has a first volume that remains constant in response to an external force applied upon the implant and the second chamber has a second volume that is changeable when the external force is applied upon the implant. The flexible diaphragm is extendible into the second chamber for reducing the second volume of the second chamber and compressing the compressible fluid within the second chamber. The compressible fluid within the second chamber provides less resistance to flexing during initial flexing of the implant and more resistance to flexing during further flexing of the implant.
摘要:
An insertion device and method of use for treating obstructive sleep apnea. The device includes an outer tubular element with a tissue penetrating end and a side opening, an inner tubular element positioned partially within the outer member and movable longitudinally relative to it, a grasping device fixedly coupled to the inner element, and a central shaft extending through the inner tubular element and movable longitudinally relative to the inner and outer tubular elements. The central shaft is slidably coupled with the grasping device. The inner tubular element is further movable between a retracted position wherein the grasping device is positioned entirely within the outer tubular element, and an extended position wherein it extends outwardly therefrom through the side opening. In the extended position, the grasping device is adapted to grasp a filamentary element positioned external of the outer tubular element and in proximity thereto.

A magnetic implant for treating sleep disorders includes a first anchor, a first magnet coupled to the first anchor, a tongue anchor, a second magnet coupled to the tongue anchor, and a support for aligning the first and second magnets so that a repelling force is generated between the magnets for urging the second magnet away from the first magnet. In one embodiment, the support aligns a magnetic pole of the first magnet with a repelling magnetic pole of the second magnet, guides movement of the first and second magnets relative to one another, and maintains the first magnet at a fixed distance from the first anchor. In one embodiment, the repelling force urges the second magnet toward the first anchor. The first anchor may be connected to bone or soft tissue.

A system for treating obstructive sleep apnea includes a body implantable in a soft palate, and a fastening element at a proximal end of the body for connecting the body with a hard palate. In one embodiment, the body is curved and has a convex top surface and a concave bottom surface. The curved body is adapted to support and/or change the shape of the soft palate for minimizing the likelihood of airway obstructions during sleep. The fastening element, secureable to the hard palate, includes at least one barb adapted to engage the hard palate for anchoring the body to the hard palate. In one embodiment, the body has a surface adapted to promote tissue in-growth. The implant body may be made of materials including nitinol, stainless steel, biocompatible polymers, temperature-sensitive materials, and shape memory materials.
摘要:
Obstructive Sleep Apnea (OSA) may be caused by a collapse of the pharyngeal wall as a result of increasing negative airway pressure. This invention is directed to systems and methods to resist collapse of the pharyngeal wall by minimally invasive upper pharyngeal airway surgery.
摘要:
An implantable tissue suspension device and its method for use. The device includes first and second filamentary elements bonded together only at a central connection region such that first and second leading and trailing legs of the respective first and second filamentary elements extend outwardly from the central connection region. The method includes implanting the device such that the central connection region extends laterally across a patient's tongue and the first and second leading and trailing legs of the first and second filamentary elements extend through the tongue such that ends thereof are positioned external to the genioglossus muscle.

摘要:
A composition for reducing pain at a surgical wound site or trauma site comprising oxidized regenerated cellulose and a non-steroidal anti-inflammatory drug or pharmaceutically acceptable salt or ester thereof, where the non-steroidal anti-inflammatory drug is an acid having a secondary amine group; and a method of reducing localized pain at a surgical wound site or trauma site.
