    • A catheter guidewire having an elongate core wire, an elongate tube defining a tube lumen, the proximal end of the tube being affixed to the distal end of the core wire. The tube has a smooth exterior surface and one or more plug segments filling the tube lumen, each plug segment having a stiffness less than that of the core wire and less than that of the proximally preceding plug segment. The proximal end of the proximal most plug segment is affixed to the distal end of the core wire, the distal end of the tube is affixed to the distal most plug segment. A smoothly rounded distal tip extends beyond and is affixed to the distal end of the tube. The tube may be formed of a super-elastic metallic member or formed from a synthetic resin. The tube wall thickness is preferably between 0.002 inches and 0.005 inches.

    • A guidewire for use in a catheter comprising a unitary core wire, a distal tip and an elongate tube. The core wire has a body segment and a transition segment, the body segment being of substantially uniform outer diameter with a distal end serially disposed proximal to the transition segment proximal end, the transition segment being more flexible than the body segment, and progressively reduced in cross-section from the body segment. The smoothly rounded distal tip is affixed to the distal end of the transition segment. The elongate tube defines a tube lumen, the core wire transition segment extends longitudinally through the tube, the tube having a uniform outer diameter equal to the outer diameter of the body segment, the proximal end of the tube being affixed to the proximal end of the transition segment, the distal end of the tube being affixed to the distal tip. The tube may be formed of a super-elastic metallic member or formed from a synthetic resin. The tube wall thickness is preferably between 0.002 inches and 0.005 inches.

    • A rivet-like bone anchor has a floating washer at its head that can adapt to an angled bone surface and, thereby, better secure a tissue thereto. The anchor includes a rivet, an expandable sleeve, and a washer. The rivet includes a head and an elongate body having proximal and distal ends, the head being mounted on the proximal end of the elongate body. The expandable sleeve has an inner bore adapted to receive the rivet body. The washer “floats” at a proximal end of the sleeve. As the rivet is inserted into sleeve, the sleeve expands into an interference fit with the bone. The head of the rivet, moreover, forces the floating washer into contact with the tissue at an angle that conforms to that of the underlying bone surface. A deployment tool permits the anchor to be deployed without application of unnecessary counterforce. The tool includes an outer tube, the distal end of which can hold the anchor housing, e.g., via a screw fit. A rod, which is slidably disposed within the bore of the tube, can be used to push the rivet into the expandable sleeve so that the sleeve expands into the bone, so that the floating washer is forced into position against the bone surface, and so that anchor is broken away from the housing. This can be effected, for example, by squeezing the distal ends of the outer tube and the rod together, e.g., in the manner that the end of a syringe is squeezed.
    • 铆钉状骨锚在其头部具有浮动垫圈，其可以适应成角度的骨表面，从而更好地将组织固定到其上。 锚固件包括铆钉，可膨胀套筒和垫圈。 铆钉包括头部和细长体，其具有近端和远端，头部安装在细长体的近端上。 可膨胀套筒具有适于接收铆钉体的内孔。 垫圈在套筒的近端“漂浮”。 当铆钉插入套筒中时，套筒膨胀成与骨头过盈配合。 此外，铆钉的头部迫使浮动垫圈以与下面的骨表面相符的角度与组织接触。 部署工具允许锚定部署，而不需要不必要的反作用力。 该工具包括外管，其外端可以例如经由螺钉配合来保持锚固壳体。 可滑动地设置在管的孔内的杆可以用于将铆钉推入可膨胀套筒中，使得套筒膨胀到骨中，使得浮动垫圈被迫抵抗骨表面的位置，因此 那个锚被从房屋里拆掉。 这可以例如通过将外管和杆的远端挤压在一起，例如以注射器的端部被挤压的方式来实现。
