Devices, methods, and kits for forming tracts in tissue |
摘要 |
Described here are methods and devices for forming tracts in tissue. Some of the devices feature an elongate member, a suction member coupled to a distal portion of the elongate member, and a tissue-piercing member slidably housed within the elongate member for forming a tract in tissue. Other devices feature more than one suction member. Methods for forming tracts in tissue are also described here. In some methods, a device is advanced adjacent tissue, where the device features one or more suction members and a tissue-piercing member. Suction is applied so that the tissue is drawn against the one or more suction members, and a tissue-piercing member is advanced in a first direction through the drawn tissue to form a tract in or through the tissue. Kits incorporating one or more of the devices described here, in conjunction with one or more tools or the like, are also described here. |

1. A device for forming a tract in tissue comprising:
an elongate member; a suction member coupled to a distal portion of the elongate member, the suction member defining a basal surface and an underside surface, the underside surface configured to support an adjacent tissue portion as the adjacent tissue portion is drawn against the underside surface by a suction load which may be applied to the suction member; and a tissue-piercing member slidably housed within the elongate member and configured to create a tract in across the adjacent tissue portion to accommodate passage of one or more tools for conducting a procedure through the tract, wherein the tissue-piercing member is configured to be advanced across at least a portion of the adjacent tissue portion such that the tract created is a self-sealing tract that generally seals without supplemental closure devices after the one or more tools have been withdrawn from the tract. |
