Abstract
An inferior vena cava filter (340) for use in the inferior vena cava (4) to capture thrombus (8) passing through the inferior vena cava (4) towards the heart and lungs to prevent pulmonary embolism comprises a proximal support hoop (302), a distal support hoop (312) and a plurality of support struts (303) extending between the proximal support hoop (302) and the distal support hoop (312). The filter (340) also comprises a plurality of capture arms (121) which are movable from a capturing configuration to an open configuration. The capture arms (121) are biased towards the open configuration. A biodegradable suture holds the capture arms (121) in the capturing configuration.
Claims19
A vascular filter comprising:
- a circumferential support frame having a first end region and a second end region;
- a plurality of arms having first ends connected to one of the first and second end regions and second free ends;
- and
- a biodegradable or bio-absorbable connection element connecting the second free ends of the plurality of arms to define an apex, wherein the apex is disposed between the first end region and the second end region;
- wherein the plurality of arms are movable from a capturing configuration to an open configuration, wherein in the capturing configuration, the second ends of the arms are connected to one another at the apex by the connection element to define a filter region, wherein upon degradation or absorption of the connection element, the second ends of the plurality of arms move to the open configuration in which the second ends of the arms are spaced apart.
A vascular filter, comprising:
- a circumferential support frame having a first end region and a second end region;
- a plurality of arms having first ends connected to one of the first and second end regions and second free ends;
- and
- a biodegradable or bio-absorbable connection element connecting the second free ends of the plurality of arms to define an apex;
- wherein the plurality of arms are movable from a capturing configuration to an open configuration, wherein in the capturing configuration, the second ends of the arms are connected to one another at the apex by the connection element to define a filter region, wherein upon degradation or absorption of the connection element, the second ends of the plurality of arms move to the open configuration in which the second ends of the arms are spaced apart;
- wherein the support frame includes a distal circumferential hoop, a proximal circumferential hoop, and a plurality of struts connecting the distal and proximal circumferential hoops.
A vascular filter comprising:
- an expandable circumferential support frame;
- a plurality of arms having first ends connected to the support frame and second free ends;
- and
- a biodegradable or bio-absorbable connection element connecting the second free ends of the plurality of arms to define an apex, wherein the apex is disposed between first and second end regions of the support frame;
- wherein the plurality of arms are movable from a capturing configuration to an open configuration, wherein in the capturing configuration, the second ends of the arms are connected at the apex by the connection element to define a filter region, wherein upon degradation or absorption of the connection element, the second ends of the plurality of arms move to the open configuration in which the second ends of the arms are spaced apart.
