    摘要： A device for clearing obstructions from a medical tube, such as a chest tube, is disclosed in various embodiments. The device features a shuttle member that is magnetically coupled to a guide wire within a guide tube, through the guide-tube wall, so that translation of the shuttle member induces a corresponding translation of the guide wire within the guide tube, without penetrating or compromising the guide-tube wall. In this manner, when the guide tube is coupled to a medical tube where obstructions have formed, the guide wire and clearance member may be inserted into and withdrawn from the medical tube, via actuation of the shuttle member, to engage and help clear such obstructions from the medical tube without compromising the sterile field. Methods of clearing a medical tube of obstructions are also disclosed.

    摘要： One aspect of the present invention relates to catheters that can be placed in or around bodily conduits to occlude or widen a biological lumen without imparting significant trauma to the lumen. In certain embodiments, the invention particularly relates to the use of a polymer composition which can be made to gel upon insertion into said balloon or skirt. In certain embodiments, the inflating viscous polymer composition is a liquid at room temperature and a gel at mammalian physiological temperature. In certain embodiments, the inflating viscous polymer composition comprises an optionally purified inverse thermosensitive polymer.

    摘要： A surgical retractor includes a “swivel” having a string extending from one end and a string extending from the midpoint between the two ends. The swivel is delivered by pushing it out of a tube which is inserted through a small incision between the ribs of the patient. After the swivel is deployed, the tube is removed and the string which is attached to the center of the swivel is pulled to lift the pericardium. When the procedure is complete, the swivel is removed from the patient by pulling the string attached to the end of the swivel. According to one embodiment, the swivel is a cylinder with a blunt conical end. According to another embodiment, the swivel has a sharp end which is covered by a spring loaded collar.

    摘要： Apparatus for reducing mitral regurgitation, including a bendable elongated body adapted to be inserted into the coronary sinus of a patient in the vicinity of the posterior leaflet of the mitral valve, the elongated body being adjustable between a first configuration adapted to be delivered into the coronary sinus and a second configuration adapted to exert a force onto the posterior annulus. The body includes a flexible spine having a proximal end and a distal end, and a flexible wire mounted on the spine and having a distal end fixed to the spine proximate to the distal end of the spine, and having a proximal portion extending from the proximal end of the spine. Axial movement of the wire causes a change in the spine from the first configuration to the second configuration to exert the force on the posterior annulus and thereby reduce mitral regurgitation.
