    摘要： A catheter for accessing a target site along a tortuous, small-vessel pathway. The catheter includes a flexible distal segment which is composed of a flexible polymer tube and a low-friction internal tubular surface. The surface allows the catheter to be advanced over sharp bends and small-diameter loops in a guidewire, in advancing the catheter along a small-vessel pathway. Various embodiments of the catheter are disclosed wherein the internal tubular surface of a distal portion of the catheter include a variety of different constructions and are comprised of a variety of different materials so as to best avoid the jamming, sticking or locking of the distal end or any part of the guidewire against the surface. Braided sleeve-like constructions, surfaces embedded with a plurality of small particles and surfaces comprised of various anti-friction materials are used in order to obtain the object of the invention.

    摘要： A guide wire formed with a distal tapered segment and having a distal-end coil carried over a portion of the tapered segment. The strand forming the helical wrappings of the coil is reduced in thickness in the region of proximal attachment to the wire, to reduce the difference in diameter between the wire and the coil. Also disclosed is a method of producing the coil.

    摘要： The self-expandable endovascular apparatus for aneurysm occlusion of the invention comprises a deformable shape memory frame with at least a partial segment covering comprised of a matrix implant material. The device can be folded and/or stretched to adopt a narrow profile for loading into a coaxial delivery device and expands in place as it adopts its original shape on release from the device into an aneurysm. A method of treating an aneurysm, comprises the steps of: (a) providing the self-expandable endovascular apparatus inserted into a lumen of a delivery device comprising a proximal end and a distal end, the distal end having a distal tip; (b) advancing the distal tip of the delivery device into an opening in an aneurysm having an interior sac; (c) advancing the apparatus through the lumen into the opening; and (d) withdrawing the delivery device, whereby the apparatus expands into the sac and covers the opening.

    摘要： An artery, vein, aneurysms vascular malformation or arterial fistula is occluded through endovascular occlusion by the endovascular insertion of a platinum wire and/or tip into the vascular cavity. The vascular cavity is packed with the tip to obstruct blood flow or access of blood in the cavity such that the blood clots in the cavity and an occlusion if formed. The tip may be elongate and flexible so that it packs the cavity by being folded upon itself a multiple number of times, or may pack the cavity by virtue of a filamentary or fuzzy structure of the tip. The tip is then separated from the wire mechanically or by electrolytic separation of the tip from the wire. The wire and the microcatheter are thereafter removed leaving the tip embedded in the thrombus formed within the vascular cavity. Movement of wire in the microcatheter is more easily tracked by providing a radioopaque proximal marker on the microcatheter and a corresponding indicator marker on the wire. Electrothrombosis is facilitate by placing the ground electrode on the distal end of the microcatheter and flowing current between the microcatheter electrode and the tip.REEAXMINATION RESULTS The questions raised in reexamination request 90/007,231, filed Oct. 4, 2004 have been considered and the results thereof are reflected in this reissue patent which constitutes the reexamination certificate required by 35 U.S.C. 307 as provided in 37 CFR 1.570(e), for ex parte reexaminations, or the reexamination certificate required by 35 U.S.C. 316 as provided in 37 CFR 1.99(e) for inter partes reexaminations.

    摘要翻译： 动脉，静脉，动脉瘤血管畸形或动脉瘘通过血管内插入铂丝和/或尖端进入血管腔而通过血管内闭塞而闭塞。 血管腔填充有尖端以阻止血液流动或进入腔中的血液，使得腔中的血块凝块和形成闭塞。 尖端可以是细长的和柔性的，使得其通过在其自身上折叠多次来包装空腔，或者可以通过尖端的丝状或模糊结构来包装空腔。 然后将尖端机械地从线分离，或者通过电极将电极与线分离。 之后取出线和微导管，留下尖端嵌入形成在血管腔内的血栓。 通过在微导管上提供不透射线的近端标记物和线上的相应指示标记，更容易跟踪导线在微导管中的移动。 通过将接地电极放置在微导管的远端并在微导管电极和尖端之间流动电流来促进血栓形成。 审议结果2004年10月4日提交的复审请求90 / 007,231中提出的问题已被考虑，其结果反映在该重新颁发专利中，该专利构成了35U.S.C.所要求的复审证书。 根据第37 CFR 1.570（e）条规定，单方面复审或35 U.S.C.所要求的复审证书。 316，如第37 CFR 1.99（e）条所述，用于跨部门复审。
