A vascular device is provided that includes a mesh structure formed of a plurality of spaced members. The structure has (i) a first, collapsed configuration, (ii) a second, expanded configuration, and (iii) a density of the plurality of members. The vascular device further includes an elastic member disposed along a region of the structure, the region having a proximal end and a distal end. The elastic member is configured to increase the density within the region by drawing at least one of the proximal and distal ends of the region toward the other of the proximal and distal ends when the structure is in the second configuration.

Methods and systems for increasing a density of a region of a vascular device

Systems and devices for endovascular treatment of intracranial aneurysms are described. Various configurations of coiled implants may be used as stenting devices or aneurysm coils. The implants include one or more filaments wound about a longitudinal axis to form a generally tubular shape. Lateral flexibility of the implants may be manipulated by, for example, adjusting a pitch between adjacent filaments, using different materials for the filaments, employing different filament cross-sectional shapes, grouping filaments into pluralities of varying flexibilities, and nesting inner coils within outer coils.

Aneurysm treatment coils

A stent delivery system includes an expandable stent, a catheter, and a sheath. The expandable stent includes proximal and distal ends, and a first interlock structure. The catheter includes an elongated member having a second interlock structure displaceably arranged about an outer surface thereof for engaging the first interlock structure of the stent. The sheath is mounted on the elongated member and is positionable in a transport position in which the sheath covers the stent mounted on the elongated member and a deploy position in which the stent is exposed.

Stent retaining systems

An implant delivery catheter enables permanent modification of the implant length in the vicinity of the treatment site prior to radial expansion thereof. The implant is releasable carried between inner and outer tubular members of the delivery catheter which, upon repositioning relative to one another using an actuator mechanism, impart any of tensile, compressile or torquing forces to the implant causing permanent modification of the implant length. In one embodiment, the circumference of the implant is substantially similar both before and after modification of the implant length. In another embodiment, the implant includes a plurality of strut sections interconnected by bridges which are capable of the deformation along the longitudinal axis of the implant.

Stretchable stent and delivery

A system for treating a patient is provided that includes an expandable vascular device having a body having a substantially uniform porosity that is adapted to change by adjusting an axial length of the body. The system also includes an expanding member positioned within a central lumen of the device, the expanding member configured to engage the body, as the body is radially expanded from a collapsed configuration, and to reduce a porosity of the body within a body region more than the body porosity is reduced outside the region.

Systems for attaining a predetermined porosity of a vascular device

A vascular device is provided that includes a mesh structure formed of a plurality of spaced members. The structure has (i) a first, collapsed configuration, (ii) a second, expanded configuration, and (iii) a density of the plurality of members. The vascular device further includes an elastic member disposed along a region of the structure, the region having a proximal end and a distal end. The Elastic member is configured to increase the density within the region by drawing at least one of the proximal and distal ends of the region toward the other of the proximal and distal ends when the structure is in the second configuration.

A method for manufacturing a vascular device that includes disposing a vascular device over an expanding member. The device includes a body having a substantially uniform porosity that is adapted to change by adjusting an axial length of the body. The method also includes adhering a portion of the body to the expanding member such that upon radial expansion of the expanding member, adherence between the body portion and the expanding member reduces a porosity of the body within the body portion more than the body porosity is reduced outside the portion.

Methods for attaining a predetermined porosity of a vascular device

An implant delivery system has one or more interlock assemblies which connect the implant delivery catheter to the implant, an improved inner tubular member and an outer tubular member. The interlock assemblies, improved inner tubular member and outer tubular member cooperate to place the implant in tension during deployment, thereby reducing implant deployment force.
