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

Disclosed herein is a delivery catheter for implanting a leadless biostimulator. The delivery catheter includes a shaft and a tubular body having a lumen and an atraumatic end. The atraumatic end includes at least one of a braided, woven or mesh construction configured to facilitate the atraumatic end changing diameter. When a distal portion of the shaft is coupled to a proximal region of the leadless biostimulator, at least one of distally displacing the tubular body relative to the shaft or proximally displacing the shaft relative to the tubular body causes the leadless biostimulator to be received in the volume of the atraumatic end and the atraumatic end to encompass the leadless biostimulator. Conversely, at least one of proximally displacing the tubular body relative to the shaft or distally displacing the shaft relative to the tubular body causes the leadless biostimulator to exit the volume of the atraumatic end.

Delivery catheter systems and methods

The present disclosure provides improved medical delivery devices for delivering a medical device into a subject. In one embodiment, the medical delivery device includes a non-porous composite inner layer constructed of a lubricious material having a plurality of pores and a thermoplastic elastomer reflowed into the plurality of pores. In other embodiments, the medical delivery device further includes a thermoplastic elastomer coated braided metallic member surrounding the nonporous composite inner layer to provide strength and structure to the device.

Medical delivery devices and methods of making and using same

A medical device is provided in which one or both ends of the device encourage the formation of tissue across substantially the entire area of the respective end that is exposed to the blood flow for reducing the risk of a thrombotic embolism. The medical device further includes stabilizing wires configured to engage tissue at a target site when the medical device is in an expanded configuration and to at least partially retract into the medical device when the medical device is in a collapsed configuration.

Percutaneous catheter directed intravascular occlusion devices with retractable stabilizing wires

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

A vascular occlusion, flow restriction, shunt or filter device is disclosed comprising the assembly of at least two, of a number of selectable discrete interconnectable, interchangeable components, at least one component being of the type fabricated from metal strands braided into a tubular metal fabric having an expanded preset configuration and an elongated, collapsed reduced diameter configuration for delivery through a catheter to a treatment site and the device shaped to create an occlusion, flow restriction or shunt when placed in an opening in a body organ or vessel, the woven metal fabric having a memory property whereby the medical device tends to return to the expanded preset configuration when unconstrained.
