ХИРУРГИЧЕСКИЙ ИНСТРУМЕНТ "ГАЛИВАТОР"

Изобретение относится к медицинским инструментам, используемым в косметологической, дерматологической и хирургической практике для удаления из пораженных участков кожи (акне, комедоны, милиумы, угревая сыпь и др.) секрета сальной железы, гнойной жидкости, спущенного эпителия, а также для удаления инородных тел из кожи. Целью изобретения является создание инструмента, обеспечивающего полное удаление содержимого из пораженного участка кожи с наименьшей травматизацией, а также высокую маневренность (возможно удаление в наиболее неудобных и малодоступных местах, например в ушах), соединяя в одном инструменте необходимые детали для всех этапов работы, связанной с чисткой пораженных участков кожи. Указанная цель достигается тем, что "Галиватор" выполнен в виде плоского дугообразного стержня с головкой полусферой и шейкой, плавно переходящей в расширенную часть стержня, являющуюся держателем, и плавно переходящего в игольчатое окончание, что обеспечивает два рабочих конца.

ХИРУРГИЧЕСКАЯ ИГЛА

Изобретение относится к медицинским инструментам, в частности к хирургическим иглам, и предназначено для ушивания ран после лапараскопии. Игла выполнена в виде спирали 1, на остром конце выбрано ушко 2 с прорезью 3, на противоположном конце иглы прикреплен барашек 4. Лигатура имеет на конце петлю с ершиком, снабженным эластичными лепестками. Петля надеваемся на конец иглы, а лигатура пропускается через ушко 2. Игла вкалывается или в стенку раны, или у ее края. Вращательными движениями с помощью барашка 4 игла погружается в ткани вокруг раневого канала, достигает нужной глубины вместе с лигатурой. При обратном вращении иглы 1 с помощью барашка 4 произойдет незначительное натяжение лигатуры, что приведет к расплавлению лепестков ерша и фиксации кончика лигатуры на этом месте. Дальнейшее обратное вращение иглы 1 приведет к извлечению иглы и удалению ее. Подтягивание за конец лигатуры, который спиралеобразно охватывает раневой канал, приведет к закрытию раны.

Energy based devices and methods for treatment of patent foramen ovale

Methods and apparatus for treatment of patent foramen ovale (PFO) provide for applying energy to tissues adjacent the PFO with a catheter device to substantially close the PFO acutely. Apparatus generally includes a catheter device having at least one energy transmission member at or near its distal end configured to apply energy to PFO tissues to acutely, substantially close the PFO. Applied energy may be monopolar or bipolar radiofrequency energy or any other suitable energy, such as laser, microwave, ultrasound, resistive heating or the like. Some embodiments of a catheter device fuirther include one or more tissue apposition members near the distal end for helping bring PFO tissues together, such as a PFO covering member, a vacuum applying member and/or the like. PFO closure via energy-based approaches of the invention may help prevent stroke, treat migraine headache, and possibly treat or prevent other medical conditions.
