Rapid exchange catheters and embolic protection devices
First Claim
1. A system comprising:
- a guidewire;
a catheter comprising;
an elongated member configured to be advanced along a vascular path of a patient, the elongated member comprising 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 portion, the sidewall exit port being dimensioned to receive the guidewire,the distal end comprising a distal port,the housing portion defining an interior cavity; and
a housing member contained within the interior cavity, the housing member having an interior space dimensioned for housing an indwelling medical device, and the housing member having a proximal end that is distal of the proximal end of the elongated member, andthe 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 encompassing the interior cavity of the housing portion,wherein the guidewire is configured to extend through the distal port, through a portion of the lumen in the housing portion, the portion extending between an interior surface of the housing portion and an exterior surface of the housing member, and through the exit port.

Abstract
A catheter compiling 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.
