| 20080275487 | REMOVABLE MEDICAL FILTER WITH STAND-OFF ARMS - A medical filter for placement in a tubular body passage. The filter has a main structure with a plurality of arms extending radially outwardly from the main structure to stand off the main structure from the wall of the tubular body passage. The filter is removed by first rotating the filter about its longitudinal axis to remove the stand-off arms from any endothelium attachments. | 11-06-2008 |
| 20080275488 | EXTENDED DURATION REMOVABLE MEDICAL FILTER - A medical filter intended for placement inside a tubular body passage of a patient has a generally longitudinally extending central spine with a retrieval element at one end; and a plurality of filter sections attached to and spaced along the spine, each of the filter sections having a plurality of radial arms attached to the spine and extending radially outwardly with parallel end segments extending axially generally parallel to the longitudinal axis, each of the end segments ending in a tip which extends radially inwardly. Each filter section may also have a graft band attached to the parallel end segments of the radial arms. | 11-06-2008 |
| 20080275489 | REMOVABLE MEDICAL FILTER - A medical filter intended for placement inside a tubular body passage such as a blood vessel of a patient, the medical filter having an end member at one end of the longitudinal axis of the filter. The end member supports a retrieval element and a plurality of struts defining a first filter cone proximate to the end member and a second filter cone distal from the end member. | 11-06-2008 |
| 20080275490 | MEDICAL FILTER WITH PARTIAL BASKETS - A medical filter intended for placement inside a tubular body passage such as a blood vessel of a patient, the medical filter having a plurality of truncated baskets positioned along a spine. Each of the baskets is rotated about the axis of the spine to be out of alignment with adjacent baskets and the spine carrying a retrieval element such as a hook. | 11-06-2008 |
| 20080275491 | REMOVABLE HELICAL MEDICAL FILTER - A medical filter intended for placement inside a tubular body passage such as a blood vessel of a patient, the medical filter having a plurality of arms radiating from an elongated spine in a helical pattern. | 11-06-2008 |
| 20080275494 | EXTENDED DURATION REMOVABLE MEDICAL FILTER WITH TISSUE BARRIER - A medical filter intended for placement inside a tubular body passage of a patient has a filter frame with a cell growth inhibiting sheet attached to the struts of the frame to prevent or minimize growth of cells over the frame after it has been implanted in a vessel or body passage of a patient. | 11-06-2008 |
| 20080275496 | CROSSOVER RETRIEVABLE MEDICAL FILTER - A retrievable medical filter which can be placed in a blood vessel or other body passage. The filter has improved structural features for enhancing its filter effectiveness and to facilitate its retrieval from the body passage. The filter has a longitudinal spine with struts extending from each longitudinal to form filter baskets. The ends of the spine to which the struts are attached may be rings with serpentine cuts in the rings to make them expandable. The struts can extend circumferentially as well as radially outwardly to provide a structure which can be radially compressed without bending the struts in a tight radius. | 11-06-2008 |
| 20090157115 | SYSTEM AND METHOD FOR RETRIEVAL OF A MEDICAL FILTER - A medical filter retrieval system for retrieval of a medial filter from placement inside a body passage of a patient has a medical filter with a ferromagnetic head at one end thereof and a retrieval catheter. Located coaxially within the retrieval catheter are an elongated central probe having a ferromagnetic end. The medical filter is retrieved from the body passage by bringing the magnetic end of the central probe into proximity of the filter head which attracts and aligns the probe end to the filter head and magnetically attaches the probe end and head. Optionally, a snare device can be coaxially located within the retrieval catheter to engage the filter after the probe has been aligned with the filter head. | 06-18-2009 |
