Rapid exchange catheters and embolic protection devices
First Claim
1. A catheter comprising:
- an elongated member configured to be advanced along a vascular path of a patient, the elongated member having a proximal portion, a distal portion, a proximal end, a distal end, a housing portion adjacent to and proximal of the distal portion, and a sidewall exit port proximal of the housing section;
the distal end comprising a distal port;
the distal portion comprising an indwelling medical device delivery structure;
the housing portion defining an interior cavity and the housing portion comprising a housing member having an interior space dimensioned for housing an indwelling medical device;
the elongated member comprising a lumen extending at least from the exit port to the distal port, the housing member being disposed within the lumen, and the lumen being dimensioned in the housing portion to receive a guidewire outside of the interior space of the housing member.

Abstract
A catheter comprising a housing portion defining an interior cavity and the housing portion comprising a housing member having an interior space dimensioned for housing an indwelling medical device. The elongated member comprises a lumen extending at least from an exit port to a distal port, the housing member is disposed within the lumen, and the lumen is dimensioned in the housing portion to receive a guidewire outside of the interior space of the housing member. A medical device for filtering emboli from blood flowing in a blood vessel of patient comprising an elongate support member and an elongate side branch member connected to the elongate support member. The filter element is attached to the elongate side branch member by a proximal filter element slider, and the elongate side branch member is adapted to maintain the filter element centered in the vessel.

56. A medical device for filtering emboli from blood flowing in a blood vessel of patient comprising:
-
an elongate support member;
an elongate side branch member connected to the elongate support member; and
a filter element being expandable from a collapsed configuration when the filter element is restrained to an expanded configuration when the filter element is unrestrained, wherein the filter element comprises a material having pores, wherein the filter element has proximal and distal portions, the filter element having a shape in the expanded configuration which defines an interior cavity having a proximal facing opening, the filter element being attached to the elongate side branch member by a proximal filter element slider, the elongate side branch member being adapted to maintain the filter element centered in the vessel. - View Dependent Claims (57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79)
