摘要： The present invention is for a stent delivery guide catheter to be used in percutaneous transluminal coronary angioplasty (PTCA). The stent delivery guide catheter consists of a guide catheter body having proximal and distal ends with a cylindrical outer wall and a coaxial inner wall defining a inner lumen. A bladder is formed between the inner and outer walls and is in fluid communication with an inflation lumen. A radially expandable and compressible stent is located inside the guide catheter body and is removably attached to the inner wall in the area of the bladder. In use, a balloon catheter is slid inside the guide catheter with the balloon positioned under the stent. When the bladder is inflated, the stent is compressed radially inward and is deposited on the balloon catheter. The present invention can also be used without the stent to facilitate the exchange of an over-the-wire balloon catheter. The balloon catheter is pulled proximal to the inflatable bladder inside the guide catheter. The bladder is then inflated and compressed to hold the guidewire while the balloon catheter is exchanged.
摘要翻译：本发明涉及一种用于经皮腔内冠状动脉血管成形术（PTCA）的支架输送导管。支架输送导管由具有近端和远端的引导导管主体组成，其具有圆柱形外壁和限定内腔的同轴内壁。膀胱形成在内壁和外壁之间并且与膨胀腔流体连通。径向可膨胀和可压缩的支架位于引导导管主体内部并且可移除地附接到膀胱区域中的内壁。在使用中，气囊导管在引导导管内滑动，气囊位于支架下方。当膀胱膨胀时，支架被径向向内压缩并且沉积在球囊导管上。本发明也可以在没有支架的情况下使用来促进线上球囊导管的交换。气囊导管被拉近到引导导管内的可充气囊。然后在更换气囊导管的同时使膀胱充气并压缩以保持导丝。

摘要： A method and apparatus for a radially expandable stent for implantation within a body vessel, comprising a first and second wire having a series of alternating peaks and valleys. The valleys of the first wire are braided with the peaks of the second wire forming a braided region with the interwoven first and second wire being wound into a continuous helix having a hollow cylindrical shape. The peaks of the first wire of the continuous helix may be welded to the adjacent valleys of the second wire of the continuous helix. The peaks and valleys of the first wire may symmetrically intersect with the peaks and valleys of the second wire to form a uniform series of crossings thereby permitting even expansion of the first and second wires. The proximal end of the first wire may be attached to the proximal end of the second wire. The distal end of the first wire may be attached to the distal end of the second wire. A means within the interwoven first and second wires of the continuous helix may be included for expansion thereof.

摘要： A method apparatus for a radially expandable stent for implantation within a body vessel, comprising a first wire formed winding and a second wire formed winding. The first wire formed winding has a hollow cylindrical shape including a preformed pattern such as a sinusoidal wave form and being wound into a continuous helix the length of the stent. The second wire formed winding has a hollow cylindrical shape including a preformed pattern such as a sinusoidal wave form and being wound into a continuous helix the length of the stent. The second winding helix is opposite that of the first winding helix. The second winding has a greater inner diameter than the outer diameter of the first winding. The second winding is coaxial with the first winding, the pattern of the first winding symmetrically intersects with the pattern of the second winding to form a uniform series of crossings thereby permitting even expansion of the first and second windings. The proximal end of the first winding may be attached to the proximal end of the second winding. The distal end of the first winding may be attached to the distal end of the second winding. An expandable member within the first winding to expand the first and second winding is included.

摘要： The present invention is accomplished by providing a method and apparatus for a radially expandable stent for implantation within a body vessel, comprising a large wire formed winding segment and 2 small wire formed winding segments. The large wire formed winding segment has a hollow cylindrical shape including a preformed pattern such as a sinusoidal wave form being wound into a continuous helix the length of the stent. The second and third wire formed winding segments have a hollow cylindrical shape including a preformed pattern such as a sinusoidal wave form wound into a continuous helix. The uniform pattern of the first, second and third wire segments permit uniform expansion of the stent. The second and third winding segments have more wire per unit surface area than the first winding segment. The second winding segment proximal end is attached to the distal end of the second winding segment to form a ring. The second winding segment is attached to the proximal end of the first winding segment. The third winding segment proximal end is attached to the distal end of the third winding segment to form a ring. The third winding segment is attached to the distal end of the first winding segment. The first, second and third winding segments may be formed of a unitary wire or may be formed from two or more wires. A member within the first, second and third winding segments to expand the first, second and third winding segments is included.

摘要： A mounting and transfer device and method for installing a stent on a delivery device that inserts the stent into a body lumen. The device includes a generally cylindrical mandrel for receiving and frictionally holding a stent, a handle at a first end of the mandrel and a guide rod extending axially from the second of the mandrel. The second end of the mandrel has a conical recess surrounding the guide rod exit. In use, a stent is placed on the mandrel, the distal end of the guide rod is fully inserted into a guide wire lumen at an end a delivery system such as a catheter and the stent is slid from the mandrel onto the balloon and crimped in place. A tube of heat shrinkable material may be placed over the stent on the mandrel and heat shrunk to lightly press against the stent. The tube and stent are transferred to the balloon and crimped. The tube protects the stent against damage during transfer and crimping and is easily removed thereafter since crimping reduces the outside diameter of the stent to less than the internal diameter of the tube.
