| 20090054924 | MEDICAL DEVICE - A collapsible filter element ( | 02-26-2009 |
| 20090099593 | EMBOLIC PROTECTION DEVICE - An embolic protection device has a collapsible filter element ( | 04-16-2009 |
| 20090099594 | FILTER ELEMENT WITH RETRACTABLE GUIDEWIRE TIP - A medical guidewire assembly comprises a guidewire having a flexible tip. A medical device such as a collaptible filter for use as an embolic protection device is mounted on the guidewire. The filter is advanced through a body lumen with the guidewire tip extending distally. At a first location the filter is advanced relative to the tip to a location which is distally advanced from the first location. Placement of the filter in an optimal distal location is thereby achieved. | 04-16-2009 |
| 20090112126 | STEPPED GUIDEWIRE WITH SHIM - A medical guidewire ( | 04-30-2009 |
| 20090112127 | NITINOL GUIDEWIRE - A medical guidewire ( | 04-30-2009 |

| 20090149881 | FILTER ELEMENT FOR EMBOLIC PROTECTION DEVICE - A collapsible filter element for a transcatheter embolic protection device comprises a collapsible filter body which is movable between a collapsed stored position for movement through a vascular system and an expanded position for extension across a blood vessel such that blood passing through the blood vessel is delivered through the filter element. A proximal inlet portion of the filter body has one or more inlet openings sized to allow blood and embolic material enter the filter body and a distal outlet portion of the filter body has a plurality of outlet openings sized to allow through-passage of blood, but to retain embolic material within the filter body. The filter body is at least partially of laminate construction comprising a membrane coated with a coating which is biocompatible, the thickness of the coating being from 4% to 40% of the thickness of the membrane. The coating may be of hydrophilic material. To facilitate retrieval of captured embolic material the distal portion and/or an intermediate portion of the filter membrane may be stretchable. The filter body may have regions of varying hardness or stiffness. | 06-11-2009 |
| 20090163612 | TISSUE ENGINEERING SCAFFOLD - A tissue engineering scaffold for cell, tissue or organ growth comprises a biocompatible porous polyurethane cellular material comprising a plurality of substantially spherical voids of diameter from 20 to 300 microns, preferably 80 to 200 microns, interconnected by generally elliptically shaped pores. The cellular material has a void content of from 85% to 98% and a surface area to volume of from 5 to 400 mm | 06-25-2009 |
| 20090209997 | MEDICAL DEVICE - A collapsible filter element ( | 08-20-2009 |
| 20090254115 | EMBOLIC PROTECTION SYSTEM - An embolic protection system comprises an embolic protection filter | 10-08-2009 |
| 20100331952 | METHOD FOR FILTERING EMBOLIC MATERIAL - The method comprises the steps of advancing a guidewire from a first intermediate location to a further intermediate location which is proximal of the treatment location and, subsequently, advancing a medical device over the guidewire toward the further intermediate location. The method may comprise repeating these steps for additional intermediate locations. In one case the treatment location is in the carotid artery. The treatment location may be at or adjacent to the carotid bifurcation. An intermediate location may be at or adjacent to the aortic arch. An intermediate location may be at or adjacent to the carotid take-off. The medical device may be delivered over the guidewire using a delivery catheter. The delivery catheter and the medical device may be advanced through the vasculature without the use of a guide catheter. | 12-30-2010 |
| 20110022164 | MEDICAL DEVICE FOR USE IN TREATMENT OF A VALVE - A medical device | 01-27-2011 |
| 20110054516 | EMBOLIC PROTECTION METHOD - An embolic protection filter for deployment in a vasculature, the filter having an inlet end and an outlet end, the inlet end having one or more inlet openings sized to allow blood and embolic material enter the filter, and the outlet end of the filter having a plurality of outlet openings sized to allow through passage of blood but to retain undesired embolic material within the filter. The filter is movable between a collapsed configuration for movement through a vasculature, and an outwardly extended configuration for deployment in a vasculature. The filter at least in the collapsed configuration was a guidewire lumen defined at least partially therethrough for passing the filter over a guidewire. The guidewire lumen is defined by a lumen-defining member which is spaced proximally of the distal end of the filter. | 03-03-2011 |
| 20110125182 | FILTER ELEMENT WITH RETRACTABLE GUIDEWIRE TIP - A medical guidewire assembly comprises a guidewire having a flexible tip. A medical device such as a collapsible filter for use as an embolic protection device is mounted on the guidewire. The filter is advanced through a body lumen with the guidewire tip extending distally. A variable thickness guidewire (having a recess or thinner segment between thicker segments) can be employed. At a first location the filter is advanced relative to the tip to a location which is distally advanced from the first location. Placement of the filter in an optimal distal location is thereby achieved. | 05-26-2011 |
