    摘要： A method and apparatus for caged stent delivery is provided herein. The device can be used to position and deliver any type of stent to a preselected treatment site within an intraluminal cavity. The device comprises a tubular portion, a plurality of arms attached to the distal end of the tubular portion, and a mechanism to open the arms. In operation, the caged device carries a stent in a constricted form to the treatment site for deployment. The arms of the cage are then opened, the stent released and deployed, and the device withdrawn. Several methods are provided to open the arms, including various pullwires, a piston, an electrolytic joint, and an activator. The arms may be constructed of a shape memory alloy and opened when shape memory behavior is effected. The device may be used with conventional catheters or used with a stent-loaded guidewire.

    摘要： A guidewire loaded stent for delivery through a catheter is described herein. The stent delivery assembly can deliver and place a stent within tortuous regions of the body which are accessible to guidewires but inaccessible to stenting catheters. The assembly comprises a guidewire covered in part by a retractable sheath and a radially expandable stent near or at the distal end of the guidewire. The whole assembly is advanced through conventional catheters or it may be used alone. In either case, when the stent is adjacent to a treatment site within the body, the sheath is retracted proximally to expose the stent for radial expansion into contact with the vessel wall. Radio-opaque marker bands are optionally located on either side or both sides of the stent on the guidewire body to aid in visual placement. The assembly can optionally include an expandable balloon on the guidewire for different treatment modalities.

    摘要： A long nose manipulatable catheter is described herein. The catheter generally comprises a flexible joint region defining a main lumen and an adjacent wire lumen. The wire lumen has an opening near or at a distal end of the flexible joint region and a push/pull wire can be pushed or pulled through the wire lumen. The catheter assembly may also comprise at least one radio-opaque marker band for securing the push/pull wire. The joint region has a predetermined length sized to affect a flexure of the joint and is generally located at the distal end of the catheter. The joint region itself may be varied to extend distally from where the braid terminates, or it may extend to encompass a portion of the braid. By varying a length of the joint region, the amount of curvature and flexure of the joint region can be controlled.

    摘要： The long nose manipulatable catheter includes a main lumen, a wire lumen with a push-pull wire therethrough, and a flexible joint region. The catheter section includes a control including a handle and a wire control member engaging the push-pull wire for manipulating the flexible joint region. The push-pull wire may be tapered, having a proximal portion of a first diameter and a smaller diameter distal portion. A coil may be placed around the smaller diameter to prevent buckling of the smaller diameter portion. A strapping coil may also disposed around the outside of the catheter, and an outer covering may be disposed around the strapping coil. An outer covering of a mesh may also be disposed around the distal tip of the catheter.

    摘要： Described herein are methods and devices that may be useful, for instance, in thrombectomy and embolectomy procedures, stent delivery procedures, and procedures for bridging the neck of an aneurysm. The bifurcated guidewire device described herein comprises a proximal end, a distal end, a length therebetween, and at least one bifurcation branching the guidewire into at least two arms. The arms are controllable, which may be accomplished, e.g., by providing arms constructed of a shape memory material, or by providing mechanical methods to control the arms. The guidewire may have any number of bifurcations branching the guidewire into any number of arms as practicable. The arms may or may not have radio-opaque markers thereon or be constructed of a radio-opaque material. The arms may have webbing or a semi-permeable sac disposed between them to help capture natural or foreign matter therein. The guidewire may be used with or without a catheter.
