Abstract
Embolic protection filtering devices and methods of making and using the same. The present invention may include an embolic protection filtering device including a filter cartridge that is slidable over medical devices, for example, guidewires. The filter cartridge may have a filter coupled thereto and may have desirable flexibility and trackability characteristics.
Claims28
A medical device, comprising:
- an elongate shaft having a proximal region and a distal region;
- the shaft including one or more stops coupled adjacent the distal region;
- a tubular cartridge slidably disposed over the shaft;
- the tubular cartridge including one or more notches defined therein;
- and
- a filter coupled to the cartridge.
An embolic protection filtering device, comprising:
- an elongate guidewire;
- a tubular filter cartridge slidably disposed over the guidewire, the cartridge having a length and a spiraling groove defined along at least a portion of the length;
- and
- an embolic protection filter coupled to the filter cartridge.
An embolic protection filtering device, comprising:
- an elongate guidewire;
- a tubular filter cartridge slidably disposed over the guidewire, the cartridge having a length and including a coil disposed along at least a portion of the length;
- and
- an embolic protection filter coupled to the filter cartridge.
An embolic protection filtering device, comprising:
- an elongate shaft
- a filter cartridge slidably disposed over the shaft;
- a filter coupled to the filter cartridge;
- and
- means for increasing the flexibility of the filter cartridge.
A method of manufacturing an embolic protection filtering device, comprising the steps of:
- providing a mandrel having an outer surface;
- disposing a filter cartridge material on the outer surface of the mandrel to define a filter cartridge;
- altering the flexibility of the filter cartridge;
- and
- coupling a filter to the filter cartridge.
A method of filtering embolic debris, comprising the steps of:
- providing a guidewire;
- providing a tubular filter cartridge having a filter coupled thereto, the filter cartridge including one or more notches defined therein to enhance the flexibility of the cartridge;
- coupling the filter cartridge to the guidewire;
- advancing the guidewire through a blood vessel to a target location;
- expanding the filter;
- advancing a therapeutic device over the guidewire;
- and
- filtering debris generated by the therapeutic device with the expanded filter.
