摘要： PROBLEM TO BE SOLVED: To provide a catheter system and a method for introducing and implanting an expandable stent member in a body.
SOLUTION: This catheter includes a catheter member, the catheter member has first and second ends, the first end has an inflatable portion 2, the catheter has a lumen 5 in fluid communication with the inflatable portion 2 and the second end, and constitutes a means for inflating the inflatable portion 2. The expandable stent member 3 is capable of permanently deforming when expanded. At least a portion of the stent member is attached to the inflatable portion 2 by a bonding portion and whereby upon inflation of the inflatable portion 2 the bonding portion is released from the stent member to permit deployment of the stent member and removal of the catheter member. The bonding portion may be formed of the same or different material than the balloon surface 7.

摘要： PROBLEM TO BE SOLVED: To provide a method for introducing an external coil supporting member into an implantable tubular prothesis made of polytetrafluoroethylene. SOLUTION: A flexible implantable tubular device is formed from a porous cylindrical tube 12 made of extruded fluoropolymer. Fluoropolymer filaments 14 are wound spirally on the outer circumference of the tube 12. The filaments 14 are fused on the tube 12 for a single synthesized construction by heating the said wound tube 12 to a temperature above the melting point of the fluoropolymer. A composite of the tube 12 and fluoropolymer filaments 14 reinforces a flexible tubular prothesis suitable for implantation, particularly a blood vessel implant or an inner prothesis, in the radial direction.

摘要： PURPOSE: To provide improved biologically compatible fluoropolymer material which can be implanted. CONSTITUTION: Biologically compatible fluoropolymer material forms an extrusion feeding flow of the first fluoropolymer component containing perfluorosulfonate copolymer and the second fluoropolymer component containing a fluoropolymer and is prepared by extruding the feeding flow and forming an extrusion. The resultant biologically compatible fluoropolymer material is useful, for example, for an artificial blood vessel.

摘要： PURPOSE: To obtain a tender and pliable surgical mesh by having a latticed support formed from multi-filament yarns closed in within the substrate insensitive to infection and constructing so that a spatial gap between filaments of the yarn is surrounded within the substrate. CONSTITUTION: A latticed support is formed by overlapping multi-filament yarns (yarns) 22, 24 in lattice at crossing connection points 25. The latticed support is closed in within the substrate 26 where the substrate 26 continuously surrounds the outer part of the yarns 22, 24 and the spatial gaps 27 positioned between filaments 28 are formed from movable material such as polymer resin, for example, polyethylene, etc., in such a manner as to be surrounded; that is, the resin is coated on the yarns 22, 24 in such a manner as for the resin not to be infiltrated inside of the yarns 22, 24. Thereby, the spatial gaps 27 are surrounded within the continuous substrate 26 rather than being filled.

摘要： PROBLEM TO BE SOLVED: To provide an implantable prosthesis with excellent blood retaining performance and to promote a curing process by improving assimilation of the peripheral tissue of the prostheses. SOLUTION: An implantable prosthesis comprises: an expanded polytetraethylene member with a structure having nodes mutually connected by fibrils at intervals and pores between nodes and fibrils; and a biodegradable composition consisting of natural resources, which are contained in the pores. The biodegradable composition forms an insoluble part of a substrate for adhering tissue by forming precipitation to almost fill holes on condition of a selected temperature and pH. A process of preparing the prostheses is also disclosed. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To obtain an interluminal stent which exhibits a high compressive strength and which can suppress inner development of a tissue by forming a wire as a wave form continuing along a length of a tube and forming the wave form as a shape continuing along the longitudinal direction with a space and without overlapped. SOLUTION: A stent 20 made of flexible biocompatible metal is formed as an approximately slender cylindrical tubular shape that is laid along the central axis. The stent is also formed by winding a wire 12 formed as a wave shape 25 on core metal spirally in order to form a structure enlarging in the longitudinal direction. At that time, each of wires is aligned continuously in the longitudinal direction with a specified interval from the adjacent wire. The interval in the longitudinal direction between spiral wires of the tube is set at twice or below of the amplitude of the wave shape. Furthermore, there is formed an open surface between wires wound spirally. The surface area of the open surface is set 30% or below of the total surface area in a closed state.

摘要： PURPOSE: To use a stent in combination with a tubular prosthesis by installing positioned cuffs at one end of a tubular conduit, the diameter of which can be varied in the radial direction and forming the tubular supplementary formation by holding the stent having a variable diameter by the cuffs. CONSTITUTION: An implantable tubular prosthesis (prosthesis) 10 is formed from a tubular conduit 12 having the first end part 14 and the second end part 16 and a tubular groove 15 is formed between both end parts 14 and 16. The prosthesis 10 may be formed preferably from dilation material, for example, knitted fabric which can be dilatable in the radial direction for a secured arrangement. In the prosthesis 10 a pair of cuffs 20, 20 are formed with each of them adjacent to the end parts 14, 16. The cuffs 20, 22 may preferably be made as self-supporting cuffs by folding the end part of the tubular conduit 12 back to the outside. The cuffs 20, 22 form open end parts 20a, 22a which hold a stent 28 with a diameter variable in the radial direction.

摘要： PURPOSE: To reduce irritation to a urethra, and expand a prostate gland by arranging a prostate gland expanding balloon on a shaft by communicating with a single lumen among two pieces, and arranging an inspecting lumen to house an inspecting means of a near part of a balloon and a dissective target point. CONSTITUTION: An expansible expanding tool of an extensible balloon 31 installed on a shaft 51 is arranged in a catheter 300. In the balloon 31, the shaft 51 is thrust into along a guide wire 50 by a naked eye observation by an aiming equipment such as a fiber optical lens 40 arranged inside a lumen in the shaft 51. A guide wire lumen 36 extends up to the distant end from the near end of the catheter shaft 51, and an inspection part 53 of the shaft 51 houses a lumen 54, and the lens 40 slides through it. An expansive part 52 houses the guide wire 50 and an expansive lumen 35, and the expansive lumen 35 is liquidly communicated with an expansive port 35a, and offers liquid to expand the balloon 31.
