Abstract
A filter system for temporary placement of a filter in an artery or vein is disclosed. The filter system includes a guidewire that is first positioned across a lesion within a vessel. The guidewire may include a distal stop. A slideable filter is then advanced along the guidewire using an advancing mechanism, typically an elongate member slideable over the guidewire and contacting the filter. A capture sheath may be disposed about the filter during advancement. Once the filter is positioned downstream of the lesion, the capture sheath is withdrawn, allowing the filter to expand. Further distal advancement of the filter is prohibited by the stop.
After expansion of the filter, the capture sheath and the advancing mechanism are withdrawn from the region of interest, and removed from the patient's vessel. The filter may then be retrieved using a capture sheath or exchanged for a second filter after removing the first filter.
After expansion of the filter, the capture sheath and the advancing mechanism are withdrawn from the region of interest, and removed from the patient's vessel. The filter may then be retrieved using a capture sheath or exchanged for a second filter after removing the first filter.
Claims (17)
1. A filter system, comprising:
a guidewire;
an elongate member having a distal region, the elongate member adapted to slideably engage the guidewire through a longitudinally extending groove in a body portion of the elongate member; and an expandable filter attached to the distal region of the elongate member, the expandable filter slideably engaging the guidewire.
a guidewire;
an elongate member having a distal region, the elongate member adapted to slideably engage the guidewire through a longitudinally extending groove in a body portion of the elongate member; and an expandable filter attached to the distal region of the elongate member, the expandable filter slideably engaging the guidewire.
2. The filter system of claim 1, wherein the filter further comprises a wire guide that engages the guidewire.
3. The filter system of claim 1, wherein the elongate member is a push wire.
4. The filter system of claim 1, wherein the elongate member is a catheter.
5. The filter system of claim 1, wherein the elongate member is a capture sheath.
6. The filter system of claim 1, wherein said expandable filter comprises a plurality of struts and a mesh disposed about the struts.
7. The filter system of claim 1, wherein the body portion has a C-shaped cross section.
8. The filter system of claim 7, wherein the elongate member further comprises at least one spiral-shaped region, the spiral-shaped region being adapted to coil about the guidewire.
9. The filter system of claim 8, wherein the wire guide comprises a ring-shaped structure.
10. The filter system of claim 1, wherein the filter has a proximal end, a distal end, and a tapered distal edge.
11. The filter system of claim 1, further comprising a sheath slideably disposed about the filter.
12. The filter system of claim 1, wherein the expandable filter is attached to the elongate member through a releasable interlock.
13. The filter system of claim 12, wherein the releasable interlock is a mechanical interlock.
14. The filter system of claim 13, wherein the mechanical interlock comprises a threaded portion on the elongate member adapted to threadably engage a matching threaded portion on the expandable filter.
15. The filter system of claim 12, wherein the releasable interlock is a magnetic interlock.
16. The filter system of claim 12, wherein the releasable interlock is an electromagnetic interlock.
17. The filter system of claim 13, wherein the mechanical interlock comprises first and second hooks and a sheath surrounding the hooks, wherein the hooks remain engaged while within the sheath, and wherein, during use, the sheath is withdrawn and the first hook is rotated out of engagement to release the filter.
