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

An intravascular balloon catheter that may include, for example, a first elongate member having a proximal end, an opening at the distal end and a lumen therebetween, a balloon defining a cavity, the balloon having a proximal waist sealingly attached to the first elongate member proximal the distal end, a distal waist, and a tubular portion therebetween, a second elongate member having a proximal end, a distal end and a lumen therebetween, the second elongate member disposed in the first elongate member and sealingly attached to the balloon distal waist, and a stopper attached to the second elongate member and disposed in the balloon cavity distal the distal end of the first elongate member, the stopper having an outer profile that prevents movement of the first elongate member thereover the first elongate member having an inner diameter at the distal end large enough to permit the passage of fluid therethrough over the second elongate member.

Balloon catheters with increased column strength

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

The invention relates to an expandable marker device having a pre-delivery state, a delivery state and at least one active region. The at least one active region incorporates electroactive polymer material. In addition, the expandable marker includes at least one radiopaque material to enhance observation through a medical imaging device.

Electroactive polymer radiopaque marker

An electrically powered linear actuator having a thrust assembly, a motor with a rotor surrounding at least a portion of the thrust assembly and a rotary encoder with a rotation sensing member rotatable with the rotor.

Electric actuator

An expandable medical balloon having at least one static state, at least one expanded state, and at least one deflated state, the expandable medical balloon including at least one active region, the at least one active region including electroactive polymer.
