A septal defect occluder is provided having first and second occluder panels. Each occluder panel includes a fabric support structure and fabric suspended therefrom. The occluder panels are conjoined at a plurality of discrete points which are located within an area bounded by each perimeter of the fabric support structures, as well as on the fabric, to thereby form a defect conforming region for the occluder. In an alternate embodiment, each occluder panel includes a cambered fabric support structure and fabric suspended from a perimeter thereof, the occluder panels being arranged in cooperative cambered opposition such that the perimeters of the cambered fabric support structures impart a clamping force upon tissue adjacent a tissue defect interposed there between when the occluder is deployed for tissue defect occlusion.

Tyco Healthcare Group LP - Mansfield MA
International Classification:
A61M 29/00
US Classification:
606200, 604269, 604104
Abstract:
The present invention provides for a drug delivery mechanism for use with a protection device. The protection device has an expandable filter. The drug delivery mechanism automatically delivers a drug to the filter without requiring the intervention of the operator of the protection device. The drug delivered to the filter facilitates continued filter patency during the medical procedure.

International Classification:
A61M 29/00
US Classification:
606200, 623 115
Abstract:
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.

International Classification:
A61M029/00
US Classification:
606/200000
Abstract:
A tissue opening occluder comprising first and second occluder portions, each occluder portion including a frame structure and an attachment structure to attach one portion to the other portion. The frames may be utilized to constrain the tissue between the two portions enough to restrict the significant passage of blood therethrough. The frame portions may be covered by a fabric suspended from a perimeter thereof. The occluder portions are conjoined at least one point on each portion.

US Classification:
600435000, 600433000
Abstract:
A system and method for sizing and imaging of cardiovascular defects generally are disclosed capable of producing model images or forms that mimic the shape of defects such as openings or breaches in cardiac septum walls, so that remedial devices of the correct size and shape can be administered to occlude defects. The system uses a three-dimensional open wire imaging structure which is flexible, easy to position and does not occlude blood flow and when expanded, can be measured in situ.
