Abstract: The invention is to provide a medical treatment tool for tubular organ which can surely capture or pick foreign substances such as calculi, other living tissues, etc. generated in a tubular organ or a body cavity and which can discharge or collect those foreign substances, other living tissues, etc. smoothly. The medical treatment tool 10b for tubular organ includes: a tube 15; a wire 25 made of a shape memory alloy and inserted in the tube 15; a basket 30b formed into a cylindrical shape by knitting and/or braiding a plurality of metal wire rods 31, a base end portion thereof being bundled and connected to a tip end portion of the tube 15, a tip end portion thereof being bundled and connected to a tip end portion of the wire 25; and a handle portion 40 which holds a base end portion of the tube 15 and which holds a base end portion of the wire 25 to allow a relative movement to the tube 15.

Abstract: The present invention provides the filter from the wire elements only, which certainly traps the thrombus and others, and easily visualizes from extra-corporeal and trapping system. The solution set forth in the present invention involves an expandable trapping filter, which is consist of plural knitted metallic wires with elastic or shape memory nature. The filter has two bundled parts in the distal and proximal ends of plural wires. When this filter expands at the intended tubular cavity of body part, each wire flips over to form parasol shape moving proximal bundled to distal bundled to catch a thrombus and others. Trapping system is deliverable from the distal edge of sheath which is interiorly loaded and is able to move in and out by the shaft movement along the penetrating shaft with the of proximal bundle immobilization.

Abstract: A stent having a stent body and a embolic body is disclosed. The stent body is collapsible for insertion into a vessel or other lumen within a patient and is radially expanded at the site of an aneurysm so that the embolic body is received within the aneurysm to support and/or promote clotting within the aneurysm. The embolic body may also be collapsible and radially expandable.
