20080275495 | RETRIEVABLE MEDICAL FILTER WITH DIVERSE BASKETS - An elongated medical filter is radially expandable and compressible and is intended for placement inside a tubular body passage, such as a blood vessel, of a patient. In expanded form, the medical filter has a spine with a retrieval element and a pair of longitudinally spaced filter baskets, one of the filter baskets having a plurality of independent legs and the other of the filter baskets having a plurality of legs with interconnecting struts. | 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 |
20090099409 | MEDICAL SHEET - A medical sheet has an intricate pattern of loops, struts and bridges and is made of a super elastic alloy. The medical sheet includes a plurality of amorphic circles which provide rounded surfaces attached to the outer edges which made the medical sheet a-traumatic when implanted. When the medical sheet is cooled the molecular phase becomes martensitic which allows the medical sheet to be compressed for easier insertion into a patient. When the medical sheet is heated, the molecular phase changes to austenitic which causes the medical sheet to expand to a size suitable for implantation. The medical sheet can be secured within the patient by suturing through holes in the amorphic circles. | 04-16-2009 |
20120058012 | SENSORS FOR DETECTING SUBSTANCES INDICATIVE OF STROKE, ISCHEMIA, INFECTION OR INFLAMMATION - A system is disclosed that extracts bodily fluid to a reaction chamber for monitoring a substance or property of the patient fluid. In one embodiment, a pump is used to advance the sample of bodily fluid through a filter to produce a filtrate. Another pump advances filtrate into the reaction chamber, while another pump advances reactant into the reaction chamber. A sensor in communication with the reaction chamber determines a concentration of nitric oxide or one of its metabolic products. Methods are also disclosed. | 03-08-2012 |

20130184740 | LONG-TERM RETRIEVABLE MEDICAL FILTER - A medical filter has more than one pair of struts extending along an undulating path between a first and second end, which cooperate to define a first and second filter element having a plurality of cells, connected by a central portion with longitudinal strut sections. The struts extend between the first and second ends, and the struts tend to resiliently expand in radially outward directions from a compressed initial shape to an expanded deployed shape. In the expanded shape, the undulating path is defined by (i) a first portion of each pair of ribs extends substantially adjacent to each other for a distance from the first end, (ii) a second portion of each pair of ribs extends substantially adjacent to each other for a distance from the second end; and (iii) an intermediate portion of each one of a pair of ribs extends to curve away from each other. | 07-18-2013 |
