One exemplary device includes a tubular structure having proximal and distal ends and at least one layer of braided material configured to facilitate thrombosis. The tubular structure includes an end section at the proximal or distal end having a cross-sectional dimension that is larger than that of an opening of the target site. The device also includes a stiffener wire coupled to the tubular structure, and the wire is configured to extend at least partially through the opening and facilitate securing the end section over the opening. The tubular structure and stiffener wire include respective preset, expanded configurations and are configured to be constrained to respective reduced configurations for delivery to the target site and to at least partially return to their respective preset, expanded configurations at the target site when unconstrained.

Medical device with stiffener wire for occluding vascular defects

A device and method for delivering a vascular device to a target site is provided that allows an orientation of the vascular device at the target site to be adjusted by a user. In general, the delivery device includes an outer tubular member, an intermediate tubular member within the outer tubular member, and an inner member that can move axially within the intermediate tubular member. Each of the members defines a proximal end and a distal end. The intermediate and outer tubular members are fixed at their respective proximal ends, but are not fixed at their distal ends. Thus, a torque applied to the proximal end of the intermediate tubular member is at least partially transmitted to the distal end of the intermediate tubular member, allowing the user to rotate an attached vascular device by rotating the proximal end of the intermediate tubular member.

Device and method for delivering a vascular device

A medical device includes a multi-layered structure comprising an inner layer disposed within an outer layer, wherein each of the inner and outer layers has respective inner and outer surfaces. The multi-layered structure further comprises at least offset located between the inner and outer layers or formed in the inner and/or outer layers to define at least one gap therebetween such that a majority of the outer surface of the inner layer is spaced apart from the inner surface of the outer layer. The multi-layered structure is configured to be deployed within a lumen such that at least a portion of the outer layer is configured to engage the lumen and the at least one gap is configured to promote thrombosis between the inner and outer layers.

Multi-layer device with gap for treating a target site and associated method

Embodiments of the present invention provide medical devices and methods for treating a target site within the body, such as for treating vascular abnormalities. For example, one embodiment provides medical device including a first tubular member that includes a first portion, a second portion, and a central portion disposed between the first portion and the second portion. Each of the first and second portions have a radius that is larger than that of the central portion, and the second portion has a preset, relaxed configuration in which a portion of the second portion has a partial discoid shape defined by an inversion of a portion of a discoid into itself.

Asymmetrical medical devices for treating a target site and associated method

A device for occluding a septal defect is provided. In general, the occluding device has a contracted state that allows the occluding device to be received within a delivery device for deployment to the site of the defect and an expanded state that is achieved when the occluding device is deployed from the delivery device. The occluding device has a proximal portion, which may be substantially circular, a distal portion, which may be substantially ovaloid, and a connecting portion extending between the two. The distal portion may define first and second outer parts at opposite ends of the major axis, which may be bent or curved. The configuration of the proximal and distal portions allow the occluding device to securely engage the septal wall and be kept in position at the septal defect without causing substantial interference with the functioning of adjacent heart structures.

Device and method for occluding a septal defect

A multi-piece head suspension assembly is manufactured from a semi-finished suspension product. The semi-finished suspension product includes a load beam having two side edges, a distal end, and a proximal end opposite the distal end. The semi-finished suspension product also includes a beam carrier strip connected to the proximal end by one or more tabs. Each tab includes a detaching region that has a lower shear strength than other regions of the tab. Rails are formed on the side edges of the load beam, and the semi-finished suspension product is attached to a hinge assembly at the proximal end of the load beam. A shear load is applied to the one or more tabs to cause the one or more tabs to fracture at the detaching region.

Full-rail suspension with shearing fracture detab

A method for manufacturing disk drive head suspension components includes supporting the components from carrier strips and/or other components by tab regions consisting substantially of a polyimide insulating layer. The components are detabbed by severing the insulating layer at the tab regions.

Polyimide tabbing method for manufacturing disk drive head suspension components

A disk drive head suspension, including a load beam formed from one or more layers of material, and a flexure mounted to the load beam. The load beam has an offset aperture and stiffening rails, and is characterized by a Z-height dimension between the one or more layers of material and the free end edges of the stiffening rails. The flexure has a slider-receiving region extending at least partially through the offset aperture and located within the Z-height dimension of the load beam. A load point structure is provided on the load beam and/or the flexure for restraining movement of the slider receiving region and for permitting slider-receiving region to pivot in under aerodynamic forces.

A flexure for attachment to a load beam in an integrated lead disk drive suspension assembly. The flexure includes a spring metal layer having slider mounting region, a first surface and a second surface opposing the first surface. A first group of conductive leads extends along at least a portion of the first surface and is separated from the spring metal layer by a first dielectric layer. A second group of conductive leads extends along at least a portion of the second surface and is separated from the spring metal layer by a second dielectric layer. A conductive interconnection extends between a conductive lead from the first group of conductive leads and a conductive lead from the second group of conductive leads. One or more leads from each of the first and second groups of conductive leads can be attached to a magnetic head.
