摘要： Embolic coil implant systems and methods whereby coils are mechanically detachable are disclosed. The coils include a retention element that may be releasably retained within the distal end of an implant tool. The implant tool may include a fulcrum configured to engage a first filament and prevent the release of the coil when the first filament is engaged. Alternatively, an urging means and aperture may be disposed within the sidewall of the implant tool, and a first filament may, in conjunction with the aperture and sidewall, releasably retain the coil until the first filament is withdrawn. The implant tool may also include an alignment member for aligning the first filament.

摘要： A vasoocclusive embolic delivery system for use in placement of an embolic coil at a treatment site within a vessel. The embolic coil includes an elongated stretch resistant fiber having its distal end bonded to the distal end of the embolic coil. The stretch resistant fiber extends through a central lumen of the coil and extends beyond the proximal end of the coil. Also included is a generally cylindrical stabilization bead, having a diameter slightly smaller than the diameter of the central lumen of the coil, mounted on the stretch resistant fiber within the lumen of the embolic coil. The stabilization bead serves to keep the stretch resistant fiber centered within the lumen of the embolic coil. Additionally, a headpiece is mounted on the proximal end of the stretch resistant fiber and serves to couple the embolic coil to the delivery system.

摘要： An intravascular implant delivery system carries an implant by retaining an engagement member engaging the implant in a position proximal of an aperture at a distal end of the delivery system. The engagement member is retained proximal to the aperture by a cord that obstructs the movement of the engagement member through the aperture. The engagement member is free to rotate and move within an area defined by the delivery system, allowing the implant to react to forces imparted to the implant by the movement of the delivery system and implant through a delivery catheter. Once the implant is in a desired implant position, the cord is moved away from an aperture and the engagement member is allowed to move away from the delivery system.

摘要： Vaso-occlusive devices for occluding a body cavity include an internal element located within a lumen of the device. The internal element may include an active element configured to stiffen the coil in-situ made from a material that can expand to a desired size, thereby inducing a radial stress to the coil to stiffen the occlusive device. Alternatively, the active element is secured to two points on the occlusive device, and is made from a material that contracts, thereby inducing a compression to stiffen the device. The internal element may additionally include an agent carrier that comprises a bioactive material capable of eliciting a biological reaction after the device is placed in-situ. For example, the bioactive material can be a part of a composition of the agent carrier, absorbed by the agent carrier, or coated as a layer on the agent carrier.

摘要： Vaso-occlusive devices are provided for occluding an aneurysm within the human vasculature. The vaso-occlusive device also includes a stretch-resisting member that extends through at least a portion of a lumen of the primary coil and is directly or indirectly attached to the primary coil at two locations axially separated from each other to prevent or minimize axial stretching of the primary coil. At one location, the stretch-resisting member is coupled to the primary coil via a flexible anchor assembly disposed within the lumen. The anchor coil is incorporated into the primary coil by disposing the anchor coil windings between the windings of the primary coil.

摘要： The present invention provides a flexible, low profile vascular occlusion device having large volume filling capability and high metal content for fast occlusion, of the type fabricated from braided tubular metal fabric having an expanded preset configuration and an elongated collapsed reduced diameter configuration for delivery through a catheter to a treatment site and shaped to create an occlusion of an abnormal opening in a body organ or vessel, the woven metal fabric having a memory property whereby the medical device tends to return to said expanded preset configuration when unconstrained. The device further includes a first shape formed from the braided tubular fabric consisting of a repeating pattern of expanded volume segments separated by small diameter articulation segments and a second overall device shape comprised of the first shape formed about itself in various shapes to occlude a vessel. In one embodiment a shaping wire contained coaxially within the tubular braid, provides or assists in the formation of the second overall device shape.

摘要： This invention is directed to implantable coils and, more particularly, to a coil implant having a stretch-resistant member internal to the coil. The implant of the invention is able to freely articulate and torque prior to delivery. Once delivered, the implant is no longer stretch resistant and is therefore able to substantially conform to the vascular site.

摘要： A vasoocclusive embolic device deployment system for use in the placement of an embolic coil at a treatment site within a vessel. The embolic coil includes an elongated stretch resistant fiber having its distal end attached to the distal end of the embolic coil. The stretch resistant fiber extends cylindrically around the outer surface of the coil and the proximal end of the stretch resistant fiber is attached to the proximal end of the coil. The stretch resistant fiber preferably takes the form of a loosely wound helical coil and may also be attached to the embolic coil at additional points between the proximal and distal ends of the embolic coil. Additionally, a headpiece is mounted at the proximal end of the embolic coil for coupling the coil to a coil deployment device.

摘要： The three-dimensional device is adapted to be inserted into a portion of a vasculature for occluding the portion of the vasculature for use in interventional therapy and vascular surgery. The device is formed from a multi-stranded micro-cable having a plurality of flexible strands of a shape memory material and at least one radiopaque strand. The flexible strands in a multi-stranded micro-cable of the device can be helically wound, or can be configured as parallel, longitudinal strands, and can also be formed to have a secondary, three-dimensional therapeutic configuration, such as helical, conical, spherical, or other geometric shapes. The strands can be made of a shape memory nickel titanium alloy, that is highly flexible at a temperature appropriate for introduction into the body via a catheter, and that after placement will take on the therapeutic shape. The device can also include a therapeutic agent, and can be bundled by an outer cover to constrain the strands of the micro-cable about a longitudinal axis to produce a composite banded cable. The radiopaque strand can have a core strand with a plurality of intermittently spaced apart enlarged radiopaque portions that may be a plurality of beads of radiopaque material spaced apart and mounted on the core strand, or a plurality of coils intermittently wound about and spaced apart on the core strand. A polyhedral occlusive device is also provided, adapted to be inserted into a portion of a vasculature for occluding a portion of the vasculature, for use in interventional therapy and vascular surgery. One or more therapeutic fibers can also be woven into the coil to enhance treatment of the side after placement of the device.
