    摘要： A collapsible medical device for use, e.g., as a vascular filter. The device includes a mandrel having a distal end and a stop spaced proximally of the distal end. A proximal length of the mandrel extends proximally of the stop and a distal length of the mandrel extends distally of the stop. A functional element (e.g., a vascular filter) has a radially expandable body and includes a proximal slider and a distal slider. The proximal and distal sliders are slidable along the mandrel independently of one another such that the distance between the proximal slider and distal slider can be varied to effect different configurations of the functional element. In one method of using such a device, the functional element is urged distally to a treatment site by urging the mandrel distally. This causes the stop to exert a distal biasing force on the distal slider, which acts against a restorative force of the functional element to axially elongate the functional element and reduce friction between the functional element and a wall of the vessel.

    摘要： An embolic protection device for removing emboli from a blood vessel in a patient's body. The device comprises a mesh element being expandable from a collapsed configuration to an expanded configuration and an elongate tubular element having a proximal opening, a distal opening, and a lumen between the proximal and distal openings. The lumen has a diameter large enough to slideably accommodate a standard guidewire. The mesh element is disposed on the elongate tubular element.

    摘要： Devices and methods for delivering stents to target vessel regions, including stent delivery through microcatheters to narrow cerebral arteries. One stent delivery device includes a stent having the distal region everted over the distal end of a delivery tube, having the everted stent distal end captured by a distal element of a elongate release member disposed through the delivery tube. The delivery tube can have a distal taper to a small profile distal end. The everted stent distal region can be captured between the release member distal element and the surrounding delivery tube distal region walls. The captured and everted stent can be distally advanced to a target site, followed by manipulating the release member to free the captured stent. Some devices utilize distal advancement of the release member while other devices use proximal retraction of the release member to free the captured stent distal end. Once released, the stent is free to self-expand or be expanded against the surrounding blockage and/or vessel walls. In some methods, a guide catheter or microcatheter is also included and disposed about the everted and captured stent to advance the stent, delivery tube, and release member to a location near the site to be stented. The devices and methods provide stent delivery not requiring an enclosing delivery sheath about the stent. The everted stent can thus have a very small distal profile enabling small diameter vessels to be crossed and treated.
