Double ended intravascular medical device
An intravascular medical device including an elongated member configured to be advanced along a vascular path of a patient, the elongated member having opposite first and second ends, the first end and second ends both being adapted for intravascular insertion, and the first end having a different structure than the second end. The elongated member has sufficient flexibility to be advanced through a human vasculature. Preferably, the first and second ends are adapted to have different operating characteristics. Depending on the operating characteristics needed for a particular procedure, a physician can insert either the first end portion or the second end portion of the elongated member into the patient's vasculature.
1. A catheter comprising:
an elongated member configured to be advanced along a vascular path of a patient, the elongated member having opposite first and second ends and corresponding first and second end portions, the first end and second ends both being adapted for intravascular insertion, the elongated member having a length and the distance between the first and second ends being the entire length of the catheter, and the first end portion comprising a delivery sheath and the second end portion comprising a retrieval sheath, wherein the delivery sheath comprises first and second sidewall ports adapted for receiving wires, a distance from the first sidewall port to the first end being less than a distance from the second sidewall port to the first end, the elongated member further comprising a lumen between the first end of the elongated member and the first and second sidewall ports, the lumen having a first diameter at the first sidewall port and a second, reduced diameter at a point between the first and second sidewall ports.
2. The catheter of claim 1 , wherein the delivery sheath comprises at least one sidewall port adapted for receiving a wire, the catheter having a lumen between the first end and the at least one sidewall port.
3. The catheter of claim 2 , wherein the sidewall port is skived.
4. The catheter of claim 1 , wherein the sidewall ports are skived.
5. The catheter of claim 1 , wherein the retrieval sheath comprises a rolled tip.
6. An assembly comprising a guide wire and a catheter of claim 1 .
7. The catheter of claim 1 , further comprising a guide wire.
8. The catheter of claim 1 , wherein an embolic protection device is adapted to be delivered and retrieved by the elongate member.
9. The catheter of claim 1 , wherein an embolic protection device is a filter.
10. The catheter of claim 9 , wherein the filter is self-expandable.
11. The catheter of claim 1 , wherein an embolic protection device is disposed in a lumen of the elongated member.
