A method of treating an aneurysm, including determining a diameter associated with a vessel having the aneurysm; selecting one of a plurality of braided implants for treating the vessel, wherein each braided implant comprises a porosity substantially consistent over up to a 1 mm diameter range, each braided implant configured to provide consistent porosity over different diameter ranges; and treating the vessel with the one of the plurality of braided implants.

Systems and methods of using a braided implant

A vascular flow diverter includes a tubular mesh framework which includes a mesh cover and an opening. The tubular mesh framework is collapsible and configured to expand from a collapsed shape to a tubular shape when the vascular flow diverter is deployed. The mesh cover conforms to the shape of the tubular mesh, is surrounded by the tubular mesh framework, and is less porous than the tubular mesh framework. The opening is located within the mesh cover. A delivery wire passes through the opening in order to guide the flow diverter into place over an aneurysm.

Delivery and detachment system for an implantable intravascular treatment device, the system including an outer delivery tube and a proximal inner tube telescopically slidable within the lumen of the outer delivery tube. The proximal inner tube has a weld window radially inward cutout defined therein along an axial section between the proximal and distal ends. A securement wire disposed axially within the lumen of the proximal inner tube is secured to an inner wall of the lumen of the proximal inner tube via at least one supplemental connection point coinciding with the weld window. Also, the method for making the delivery and detachment system wherein one or more positioning wires threaded through the lumen of the proximal inner tube are manipulated to force the securement wire and the proximal inner tube in direct physical contact with one another along an axial section coinciding with the weld window.

A method is disclosed, including joining a balloon to a resilient inner body of a balloon assist device, the balloon comprising an axial length shorter than an axial length of the inner body; expanding a slit in the resilient inner body of the balloon assist device; inserting a catheter through the slit; and releasing the slit to contract the balloon assist device around the catheter.

A self-expanding braided stent includes at least a distal radial expansion ring added to a distal end of the stent body to increase a radial expansion force of the self-expanding braided stent in deployment of the stent, and to facilitate advancement of the stent through a delivery sheath by a core advancement wire. A proximal radial expansion ring is optionally added to a proximal end of the stent body to allow the stent to be recaptured following partial deployment by retraction of the core advancement wire, prior to full deployment of a proximal portion of the stent body.

Braided stent with expansion ring and method of delivery

A generally tubular braided flow diverting stent is formed of alternating round and rectangular elongated members, for treatment of aneurysms. The generally tubular braided flow diverting stent maintains a significant wall thickness while increasing area coverage of a vessel wall. Sliding of the round elongated members over the rectangular elongated members allows the stent to be crimped to very low diameters for delivery in narrow portions of the vasculature.

An occlusion device that includes an inner embolic element with a proximal section and a distal section, wherein the distal section has a first stiffness and the proximal section has a second stiffness. An expandable mesh is included that is capable of being transformed between a collapsed position and an expanded position, wherein the expandable mesh is disposed over a portion of the proximal section of the inner embolic device and the first stiffness is greater than the second stiffness.

Expandable vascular occlusion device with lead framing coil

A method of treating an aneurysm with an occlusion device having an inner embolic device with a proximal section and a distal section. The distal section has a first stiffness and the proximal section has a second stiffness. Further, the device has an expandable mesh capable of a collapsed position and an expanded position. The mesh can be disposed over, and attached to, a portion of the proximal section of the inner embolic device. The first stiffness is greater than the second stiffness and the inner embolic device comprises a preselected shape which assists in transforming the expandable mesh from the collapsed position to the expanded position.

A method for implanting a stent by providing an implantation system including a catheter, an expandable element, and a delivery wire, moving a first portion of the expandable element to exit the catheter, and maintaining a second portion of the expandable element within the catheter to establish a partially implanted configuration. Then moving the delivery wire independent of the expandable element in the partially implanted configuration, and enlarging a circumference of the expandable element in response to the moving the delivery wire.

Stent delivery with expansion assisting delivery wire

Methods of making an implant for medical use, having a body formed of a plurality of single strands of a first material. The body further includes at least one multi-strand of radiopaque material incorporated among the single strands, the multi-strand having at least two side-by-side filaments of radiopaque material that lie substantially contiguous to each other over substantially the entire length of the multi-strand.

Method of making a multi-strand implant with enhanced radiopacity

A system is provided to effectively position a stent within a vessel. The system includes a delivery catheter and a core wire extend through the catheter. The core wire includes an engaging surface region and a capture member disposed thereon, which cooperate to engage a stent such that the stent is able to be advanced or retracted with the advancement or retraction of the core wire. The engaging surface region and the capture member can generally be configured to engage the stent when a portion of the stent is disposed within the lumen of the catheter, and release the stent when no portion of the stent is within the lumen.

Stent delivery system and method

A capture tube mechanism for delivering and releasing a self-expanding stent includes a core wire on which a proximal portion of the stent is removably retained by a distal portion of a tubular capture sleeve. In one embodiment, one or more elongated members extending through corresponding apertures through the capture sleeve and out the distal end of the capture sleeve can be pulled to split the tubular capture sleeve to release the stent. In another embodiment, the capture sleeve can be pulled proximally over one or more stop members provided on the core wire to release the stent.
