Abstract
An embolic protection filtering device and method of making and using the same. The present invention comprises a filtering device including an elongate shaft and a filter that may be releasably attachable to the shaft. The filter may include a coupling member that may be used to secure the filter to the shaft.
Claims26
An embolic protection filtering device for coupling to an elongate shaft, comprising:
- a filter capable of being completed to the elongate shaft, the filter including an inflatable coupling member and an inflatable expansion member;
- and
- wherein the inflatable coupling member is adapted to shift between a first deflated configuration in which the filter is slidable along the longitudinal axis of the wire, and a second inflated configuration in which the position of the filter is substantially fixed relative to the shaft.
An embolic protection filtering device, comprising:
- an elongate shaft having a proximal end and a distal end;
- a filter coupled to the shaft, the filter including a proximal mouth region, a filter membrane region, a distal region, and an inflatable coupling member disposed at the distal region;
- and
- wherein the inflatable coupling member is adapted to shift between a first deflated configuration in which the filter is slidable over the shaft, and a second inflated configuration in which the position of the filter is substantially fixed relative to the shaft.
A medical device, comprising:
- a guidewire;
- a filter disposed adjacent the guidewire;
- and
- means for releasably attaching the filter to the guidewire.
A medical device, comprising:
- an elongate guidewire;
- a filter disposed adjacent the guidewire and including a distal coupling member;
- and
- the coupling member being adapted and configured to releasably secure the filter to the guidewire.
A medical device, comprising:
- an elongate shaft;
- a filter coupled to the shaft;
- a coupling member coupled to the filter, the coupling member including one or more gripping arms;
- wherein the gripping arms pivotable about a pivot point between a first position where the filter is slidable along the shaft and a second position where the arms secure the position of the filter relative to the shaft;
- an expansion member coupled to the filter and to the coupling member;
- and
- wherein radial expansion of the expansion member pivots the coupling member into the second position.
A method for coupling a filter to a guidewire, comprising the steps of:
- providing a guidewire;
- providing a filtering assembly, the filtering assembly including a filter having an inflatable coupling member attached thereto;
- advancing the filter assembly along the guidewire to a desirable position;
- and
- inflating the coupling member so as to secure the filtering assembly to the guidewire.
A method for filtering debris from a body lumen, comprising the steps of:
- providing a guidewire;
- providing a filtering assembly, the filtering assembly including a filter having an inflatable coupling member attached thereto;
- inflating the coupling member so as to secure the filtering assembly to the guidewire;
- advancing the guidewire to a target location within a body lumen;
- expanding the filter;
- and
- capturing embolic debris on the filter.
