Embodiments of the present invention provide an improved vascular occlusion device for occlusion of a passageway, cavity, or the like. According to one embodiment, a medical device for occluding a left atrial appendage is provided. The medical device includes a first portion having at least one plane of occlusion that is configured to be positioned outside of the left atrial appendage, and a second portion having at least one plane of occlusion that is configured to be at least partially positioned within a cavity defined by the left atrial appendage.

Percutaneous catheter directed intravascular occlusion devices

Embodiments of the present invention provide medical devices and methods for treating a target site within the body. For example, one embodiment provides a stent graft for treating a target site proximate to a bifurcated lumen, wherein the stent graft includes a first tubular structure having proximal and distal ends and a side wall extending therebetween. The first tubular structure includes an opening defined within the side wall and is configured to define a first portion having first and second ends and a second portion having first and second ends. The opening corresponds to the first ends of the first and second portions and the second ends of the first and second portions respectively correspond to the proximal and distal ends of the first tubular structure, and at least a portion of the first and second portions are configured to be positioned within respective branches of a bifurcated lumen.

Bifurcated medical device for treating a target site and associated method

A collapsible medical device and associated methods of occluding an abnormal opening in, for example, a body organ, wherein the medical device is shaped from plural layers of a heat-treatable metal fabric. Each of the fabric layers is formed from a plurality of metal strands and the assembly is heat-treated within a mold in order to substantially set a desired shape of the device. By incorporating plural layers in the thus-formed medical device, the ability of the device to rapidly occlude an abnormal opening in a body organ is significantly improved.

Multi-layer braided structures for occluding vascular defects

Embolic protection devices and systems capture and/or deflect emboli from entering one or more arterial branches of the aorta. An embolic protection device may include an anchor section that is positionable within an arterial branch of the aorta and a shield section that is operatively coupled to the anchor section. The shield section is positionable relative to one or more ostia of the aortic branches and is held in that position by the anchor section.

Embolic protection device

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 distal protection device for use in a body lumen. The device includes a functional element which may be a filler or an occlusive element. The device includes means for controlling the movement and placement of the functional element along a guidewire. Motion of the guidewire can be independent of the motion of the functional element.

Distal protection devices having controllable wire motion

In some embodiments, a medical device may include one or more of the following features: (a) a metal fabric formed of braided metal strands, (b) the medical device having a collapsed configuration for delivery through a channel in a patient's body and having a generally dumbbell-shaped expanded configuration with two expanded diameter portions, separated by a reduced diameter portion formed between opposed ends of the device and unsecured metal strand ends at the opposed ends, and (d) a thrombogenic agent located on the metal fabric.

Braided vascular devices having no end clamps
