Abstract: In one embodiment according to the present invention, a stent is described having a generally cylindrical body formed from a single woven nitinol wire. The distal and proximal ends of the stent include a plurality of loops, some of which include marker members used for visualizing the position of the stent. In another embodiment, the previously described stent includes an inner flow diverting layer.

Abstract: A stent with varying porosity is described. The stent can be comprised of multiple stents attached together. A braided stent may have selected regions of increased thickness. The stent may be comprised of wires that are welded together at their ends in order to minimize vessel trauma. The stent may comprise a helically wound radiopaque wire wound through the stent.

Abstract: A system and method for quickly detaching an implant and for locating the detachment zone of a detachable implant. A sensor determines a sudden change in the local environment as the sensor passes from within a microcatheter to being exposed to the vasculature. The sensor may be a temperature sensor, ultrasonic sensor, pressure sensor or the like. If the detachable implant assembly uses a heater coil to detach the implant, the heater coil may be used as a sensor. Additionally, the implant itself may be used as a sensor if a change in electrical resistance is detectable as the implant exits the microcatheter and changes shape.

Abstract: Implant engagement mechanisms are disclosed for maintaining engagement with a stent until it has been fully deployed and expanded from a catheter or sheath. The apparatus, method and system involving these engagement mechanisms allow a physician to withdraw or retract a sheath prior to full deployment, thereby allowing for redeployment of the stent at a more desirable position.

Abstract: A system and method of delivering and detaching an implant within a body of a patient is described. A tether connects an implant with a delivery device. The delivery device includes a heater coil through which the tether passes. The inner diameter of the heater coil is about the same size or slightly larger than the outer diameter of the tether, allowing the tether to more efficiently break the tether during delivery.

Abstract: One embodiment according to the present invention includes an occlusion device in which the support structure or frame expands circumferentially within the lumen to secure an expansile plug or embolic material. Once in place, the expansile plug or embolic material expands, thereby occluding the target lumen. Another embodiment according to the present invention includes a radially expandable support structure having a closed portion for capturing subsequently delivered embolic material, such as embolic coils. For example, the structure may have a closed portion at its distal end or at its middle (forming an hourglass shape). Additionally, the closed portion may be formed from the support structure itself or from a discrete, second layer that is attached within the support structure.

Abstract: In one embodiment, the present invention relates to a mechanically releasable delivery system. More specifically, this embodiment includes an implantable device secured by tether at a distal end of the delivery system. The tether is fixed to the implantable device and looped around a selectively slidable mandrel. When the mandrel is retracted to expose its distal end, the looped tether slides off the mandrel, freeing the implantable device. Alternately, the tether can be fixed to the delivery system, wrapped around a portion of the implantable device and looped on to the slidable mandrel. Preferably, movement of the mandrel is controlled by an actuation control on the handle of the delivery system, allowing the user to selectively release the implantable device during a medical procedure.
