    • A stent delivery and deployment system for use primarily with self-expanding stents, incorporating a traction tube extending over the length of the diametrically compacted and constrained stent and everting back over itself, with the outer everted portion of the traction tube preferably extending to the proximal end of the delivery system. A constraining sleeve is provided between the inner, non-everted portion and outer, everted portion of the traction tube, the constraining sheath extending over the length of the constrained stent prior to deployment and diametrically constraining the diametrically compacted self-expanding stent. The application of tension to the proximal end of the traction tube causes the constraining sheath to move in a proximal direction, freeing the constrained stent as it moves and allowing the stent to deploy against the wall of the body conduit within which it is located during the deployment process.

    • A deployment sheath for medical devices is provided that includes one or more pleats in its pre-deployment state that are allowed to open during deployment so as to facilitate easier device deployment and sheath removal. Preferably, the sheath is removed by everting it over itself during the delivery process. By orienting the pleats along the length of the sheath, preferably helically around the sheath, the sheath undergoes a predictable enlargement during deployment so as to relieve friction of the everted sheath sliding along itself during deployment. This allows the sheath to be removed with less tension than previous everting sheath constructions and assures more accurate device placement in a patient.
    • 提供了用于医疗装置的部署护套,其包括其部署前状态下的一个或多个褶皱,其在展开期间被允许打开,以便于更容易的装置展开和护套移除。 优选地,在输送过程中,通过将其自身除去,从而去除护套。 通过沿着护套的长度定向褶皱,优选地围绕护套螺旋地定向褶皱,护套在展开期间经历可预测的放大,以便减轻在展开期间沿着其自身滑动的外翻护套的摩擦。 这允许以比先前的护套构造更少的张力去除护套,并且确保在患者中更准确的装置放置。

    • An improved tubular structure adapted to increase in diameter upon application of axial force is provided. Increase in diameter is achieved by constructing the tube from multiple layers of material that move relative to each other during axial elongation of the tube. The tube of the present invention can be used both to avoid problems in “necking” found in many prior tube devices, and to provide additional benefits that increases in diameter of the tube during axial elongation can provide. As such, the tube of the present invention may be useful as a manufacturing aid, as a deployment sheath (for example, to deliver medical devices), and in other applications that may benefit from easier tubular sheath removal.
    • 提供了一种适于在施加轴向力时直径增加的改进的管状结构。 通过在管的轴向伸长期间通过相对于彼此移动的多层材料构造管来实现直径的增加。 本发明的管可用于避免在许多现有管装置中发现的“颈缩”问题,并且提供在轴向伸长可以提供的管的直径增加的附加益处。 因此,本发明的管可以用作制造辅助部件,例如作为部署护套(例如,用于输送医疗装置)以及可能受益于更容易的管状护套移除的其它应用。

    • A suture needle having, in sequence, a shaft portion, a tip portion, a conical point portion and a point. The shaft portion may be straight or curved, and cylindrical or tapered. The tip portion has at least two substantially flat surfaces. The conical point portion is of conical shape having a substantially round cross section adjacent to the point of the needle. A plane tangent to the surface of the conical point portion makes a greater angle with respect to the longitudinal centerline of the needle than does the angle formed by the intersection of a plane through a flat surface of the tip portion and the longitudinal centerline of the needle.
