Flexible expandable treatment devices are disclosed herein. One aspect of the present technology, for example, is directed to an expandable tubular structure formed of an interwoven strand and configured to be positioned in a blood vessel. The interwoven strand may be arranged to form a plurality of cells and a plurality of joints between adjacent cells. At least one of the joints may include a first strand slidably interlocked with a second strand, and at least one of the first strand and the second strand may bend back on itself to form a restriction that limits disengagement of the first strand and the second strand at the joint.

Flexible intravascular treatment devices and associated systems and methods of use

Guidewires and methods of use of guidewires having improved atraumatic tips that can distribute force to lessen trauma as well as anchor the guidewire to facilitate improved catheter exchange.

Expandable tip medical devices and methods

A hollow guidewire with a shapeable distal end, for removing tissue from a body lumen, such as a coronary artery. The hollow guidewire comprises an elongate, tubular guidewire body that has an axial lumen. A tissue removal assembly, such as a rotating drive shaft, is positioned at or near a distal end of the tubular guidewire body and extends through the axial lumen. Actuation of the tissue removal assembly removes occlusive material in the body lumen.

Guidewire for crossing occlusions or stenoses having a shapeable distal end

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. In one embodiment, the anchor assembly may comprise an anchor coil and a link directly or indirectly coupled between the anchor coil and the stretch-resisting member. Alternatively, the anchor assembly may comprise a chain of twisted links.

Anchor assemblies in stretch-resistant vaso-occlusive coils

This is an implantable vaso-occlusive coil which is implanted using minimally invasive surgical techniques. It is a complex, helically wound coil made up of a primary helically wound coil which is then wound into a specific secondary shape. The secondary shape is itself a series of helical turns. At least a portion of the turns in the secondary shape form a cylindrical region and adjacent that region on at least one end is a conical region which tapers from a diameter approximating that of the central cylindrical region to a smaller diameter. The device is desirably self-forming upon exit from the distal end of a delivery catheter. Also, the conical tipped vaso-occlusive device may also utilize thrombus-enhancing filamentary material.

Vaso-occlusive coil with conical end

A device for occluding a space within the body, and particularly,the device usefle as a vaso-occlusive device. In partiular, the device typically comprises a metallic core or core member, and two polymeric conjuncts, often polymeric members, of differing thrombogenicity. Typically, the core member comprises a metallic helically-wound coil; the first polymeric member and second polymeric member are fibrous materials woven into a braid. The device may be placed at the desired site within a mammal to facilitate the formation of an occlusion. The device promotes the formation of scar tissue, healing tissue, or neocapillaries in vascular occlusions made by the device.

Vaso-occlusive device with attached polymeric materials

This is a device for bridging the neck of either a wide-necked or narrow-necked aneurysm as may be found in the vasculature. It may be used to stabilize the placement of vaso-occlusive devices such as helically wound coils in the aneurysm or may be used to, at least partially, close the aneurysm neck. The vaso-occlusive devices, commonly helically wound coils, are delivered by a core wire which is linked to the coils by an electrolytically severable joint. The core wire will often be insulated. The retainer assembly itself is also attached to another delivery device, such as a core wire, and desirably is severed from the core or delivery wire by the use of another electrolytically severable joint. The inventive neck bridge typically has a number of array elements which are intended to be resident within the aneurysm after the device is deployed from the distal end of a catheter. Central to this invention is the use of array elements having differing flexibility or constituent members of the array elements, e.g., wires making up the array elements, which are of differing flexibilities. After deployment of this retainer, the aneurysm may be at least partially filled with vaso-occlusive devices such as helically wound coils.

Detachable, varying flexibility, aneurysm neck bridge

This is a device for occluding a space within the body, and particularly, it is useful as a vaso-occlusive device. In particular, it typically comprises a metallic core or core member, and two polymeric conjuncts, often polymeric members, of differing thrombogenicity. Typically, the core member will comprise a metallic helically-wound coil; the first polymeric member and second polymeric member will be fibrous materials woven into a braid. These devices may be placed at the desired site within a mammal to facilitate the formation of an occlusion. The inventive device has been found to promote the formation of scar tissue, healing tissue, or neocapillaries in vascular occlusions made by the device.
