An intraluminal device including an elongated structure formed of a plurality of wires may be provided. The intraluminal device may include a plurality of sets of looped wires longitudinally located at an intermediate area of the elongated structure. The sets of looped wires may be spaced circumferentially about the elongated structure and may be configured to cooperate with each other to form a plurality of clot entry openings. The intraluminal device may also include at least one grouping of woven wires that may be longitudinally located adjacent to the intermediate area and may be configured such that when an opening force is exerted on the elongated structure, the at least one grouping of woven wires may provide structural support to hold open first interstices between the plurality of sets of looped wires.

Woven wire intraluminal device

An intraluminal device may be provided including an elongated structure formed of a plurality of wires. The intraluminal device may include at least one expandable mesh segment configured to engage an obstruction in a body lumen, wherein the plurality of wires may be arranged into sets of looped wires that overlap to form the expandable mesh segment. The intraluminal device may also include at least one clot anchoring segment that may be configured to trap the obstruction to prevent downstream movement of the obstruction relative to the intraluminal device.

Controllable retriever with distal clot anchor

An intraluminal guide wire may include an elongated shaft extending between a distal and a proximal end. The guide wire may include a user actuation segment positioned proximal to the proximal end of the shaft and configured for movement relative to the shaft. The guide wire may include a core wire affixed to the user actuation segment and the distal end of the shaft. The guide wire may also include an inner member having a proximal end situated at least partially within and fixed relative to the user actuation segment and a distal end situated partially within the shaft, the core wire passing through the inner member. The guide wire may be configured with a distal segment of the inner member within the shaft exhibiting a friction-based restraint on movement within the shaft. The friction-based restraint on movement may be a frictional force between the inner member and the shaft.

Guide wire activation mechanism and proximal actuation mechanism

Endovascular and intravascular devices and methods of manufacturing endovascular and intravascular devices may be provided. In one implementation, an intravascular device including an elongated sheath and an elongated coil distal to the sheath may be provided. The coil may include a first coil segment formed from a plurality of wires helically-wound at a first coil angle; a second coil segment formed from a first subset of the plurality of wires that is helically-wound at a second coil angle that is different from the first coil angle; and a third coil segment formed from a second subset of the plurality of wires that is helically-wound at a third coil angle that is different from the first and second coil angles. The coil segments may be configured such that flexibility of the coil increases in a longitudinal direction toward the distal end of the coil.

Rotationally torquable endovascular device with variable flexibility tip

An intraluminal device and a method of removing a clot from a body lumen with an intraluminal device may be provided. The intraluminal device may include a hollow elongated shaft and a radially-expandable mesh segment situated distal to the elongated shaft. The elongated shaft may be secured relative to a first portion of the mesh segment. The intraluminal device may additionally include a core wire affixed to a second portion of the mesh segment and extending through the elongated shaft. The elongated shaft may be configured to radially expand the mesh segment by axially moving the first portion of the mesh segment relative to the second portion of the mesh segment. In addition, the core wire may be configured to radially expand the mesh segment by axially moving the second portion of the mesh segment relative to the first portion of the mesh segment.

Radial expansion control mechanisms for intraluminal device

Intraluminal and endovascular devices and methods of manufacturing intraluminal and endovascular devices may be provided. In one implementation, an intraluminal device may include a sheath having a flexible distal bending segment and a core wire arranged within the sheath. The core wire may include a distal end portion doubled back in a loop within the sheath such that the distal tip of the core wire is situated proximally from the loop. The intraluminal device may also include a movement restrictor within the sheath that is configured to limit axial movement of the distal tip of the core wire. Limiting the axial movement of the core wire distal tip may cause the loop of the core wire to buckle, resulting in a bend in the distal bending segment of the sheath, when a force is exerted on the core wire.

In one exemplary embodiment, an endovascular device may include a hollow shaft having a proximal end and a distal end, and sized for insertion into a blood vessel. The endovascular device may also include a control line having a proximal end and a distal end, and extending through the hollow shaft. The endovascular device may also include an actuatable working element located proximate the distal end of the hollow shaft, and configured to receive an actuation force transmitted via the distal end of the control line. The endovascular device may further include an actuator configured to exert the actuation force on the proximal end of the control line, to thereby cause relative movement between the control line and the hollow shaft and to actuate the working element. The hollow shaft may also include a cable formed of a plurality of wound wires and including a proximal segment, at least one transition segment, and a distal segment. The proximal segment, at least one transition segment, and distal segment may include different numbers of wires.

An endovascular device including a hollow shaft having a proximal end and a distal end, and sized for insertion into a blood vessel, may be provided. The endovascular device may also include a control line configured to extend through the hollow shaft and an actuatable working portion situated distally from the distal end of the hollow shaft and configured to receive an actuation force transmitted via the control line. The endovascular device may further include an actuator configured to exert the actuation force on the control line to cause relative movement between the control line and the hollow shaft and to actuate the working portion. The endovascular device may also include a rotation restriction barrier configured to substantially impede the control line from rotating relative to the working portion, while permitting relative axial movement between the control line and the hollow shaft.

Continuously variable transmission with auxiliary drive

A drive system for a high-inertia load, such as a motor vehicle including a fly-wheel, comprises a prime-mover for setting the high-inertia body into motion and for maintaining the motion thereof during the operation of the drive system, a driven device driven by the high-inertia body, a bi-directional variable speed unit coupling the high-inertia body to the driven device for controlling its speed during the operation of the drive system such that when the driven device is accelerating it draws energy from the high-inertia body, and when it is decelerating it returns energy to the high-inertia body, and a control system automatically controlling the prime-mover to supply sufficient energy to the high-inertia body to make up for losses. Two types of control systems are described, one being energy-responsive, and the other being power-responsive.
