摘要： An adjustable annuloplasty device is described. The device includes a body member comprising a shape memory material, the body member configured to be placed at or near a base of a valve of a heart. The device further includes a hysteretic material configured to undergo magnetic hysteresis in response to a first activation energy, the hysteretic material being in thermal communication with the shape memory material. The body member may have a first size of a body member dimension in a first configuration and a second size of the body member dimension in a second configuration. When the body member is in position in the heart, a change from the first configuration to the second configuration changes a size of a dimension of the annulus of the valve.

摘要： A prosthetic implant for treating a diseased aortic valve is described. The prosthetic implant includes a substantially tubular body configured to be positioned in an aorta of a patient, at or near the patient's aortic valve. The body includes a lumen extending through the body from a proximal end to a distal end of the body; and an adjustable frame surrounding the lumen. The prosthetic implant further includes at least one adjustable element located in or on the body and extending at least partially around a circumference of the lumen. The at least one adjustable element includes a shape memory material and is transformable, in response to application of an activation energy, from a first configuration to a second configuration, wherein the first configuration and second configuration differ in a size of at least one dimension of the at least one adjustable element. The at least one adjustable element may engage at least one of a root of the aorta, an annulus of the aortic valve, and the patient's left ventricle, when the at least one adjustable element is in the second configuration.

摘要： Disclosed is a device and method for accessing the lower esophageal sphincter through the esophagus. In one embodiment, a catheter is inserted through the mouth or nose of a patient and advanced to the region of the diaphragm. Under fluoroscopy or endoscopy, a hollow needle at the distal end of the catheter punctures the wall of the esophagus from the inside so that the distal end of the needle is positioned outside the esophagus. An implant is next advanced out through the hollow needle to the region outside the sphincter where it is deflected and coerced to bluntly dissect around the circumference of the esophagus, where the implant is left in place to heal. The hollow needle is removed and the esophageal wall is allowed to heal. Subsequent diametric adjustment of the implant allows for tightening or loosening of the sphincter to minimize gastric reflux. The device and method can also be used to treat the pyloric or other body sphincters, hollow organs, or ducts.
摘要翻译：公开了一种通过食道进入下食管括约肌的装置和方法。在一个实施例中，导管穿过患者的嘴或鼻插入并前进到隔膜的区域。在荧光透视或内窥镜检查下，导管远端的中空针头从内侧穿刺食道的壁，使得针的远端位于食道外部。然后将植入物通过中空针前进到括约肌外部的区域，在那里它被偏转并胁迫以在食道周围钝化解剖，植入物留在原位以愈合。取出空心针，食管壁被治愈。随后的植入物的直径调整允许收缩或松开括约肌以最小化胃反流。该装置和方法还可用于治疗幽门或其他身体括约肌，中空器官或管道。

摘要： Disclosed is an expandable transluminal sheath, for introduction into the body while in a first, low cross-sectional area configuration, and subsequent expansion of at least a part of the distal end of the sheath to a second, enlarged cross-sectional configuration. The sheath is configured for use in the vascular system and has utility in the performance of procedures in the left atrium. The access route is through the inferior vena cava to the right atrium, where a trans-septal puncture, followed by advancement of the catheter is completed. The distal end of the sheath is maintained in the first, low cross-sectional configuration during advancement to the right atrium and through the atrial septum into the left atrium. The distal end of the sheath is subsequently expanded using a radial dilatation device. In an exemplary application, the sheath is utilized to provide access for a diagnostic or therapeutic procedure such as electrophysiological mapping of the heart, radio-frequency ablation of left atrial tissue, placement of left atrial implants, mitral valve repair, or the like.

摘要： Disclosed is an expandable transluminal sheath, for introduction into the body while in a first, small cross-sectional area configuration, and subsequent expansion of at least a part of the distal end of the sheath to a second, enlarged cross-sectional configuration. The sheath is configured for use in the vascular system and has utility in the introduction and removal of implant delivery catheters. The access route is through the femoral arteries and the iliac arteries into the aorta. The distal end of the sheath is maintained in the first, low cross-sectional configuration during advancement to the arteries into the aorta. The distal end of the sheath is subsequently expanded using a radial dilatation device, which is removed prior to the introduction of implant delivery catheters. In an exemplary application, the sheath includes a supported proximal end, a supported distal end, and a collapsible center section. Certain configurations of the sheath are capable of being inserted in a first, small cross-sectional configuration, being expanded diametrically to a second, larger cross-sectional configuration, and then being reduced to a diametrically small size for removal.

摘要： Devices and methods are disclosed for achieving control and stabilization of bone fractures in mammals, most specifically humans. Stabilization and traction is often required to support fractured bones of the arms or legs. The devices and methods disclosed herein are especially useful in the emergency or military setting. The devices utilize a collapsible frame or inflatable member that may be expanded and locked into position. The frame or inflatable member is fabricated primarily from polymeric materials with low radiodensity. The limb contact regions are adjustable to fit a wide variety of limb sizes and fracture locations. The traction applied by the splint is adjustable, controllable and measurable. The traction splint is sufficiently compact that it will fit in a compartment of most ambulances and emergency rescue vehicles, thus making it more available for use than standard traction splints in use today. The traction splint is either a separate device or integrated into a backboard.
