Abstract

Medical devices and methods of manufacturing medical devices. The medical devices include an elongate member having a proximal portion (14) and a dist al portion (16) and a connector assembly (12) disposed adjacent the elongated member to connect the proximal and distal portions, the connector assembly including a radiopaque marker (18a, 18b, 18c).

Claims (28)

1. A medical device comprising:
an first elongated member having a proximal portion and a distal portion;
an second elongated member having a proximal portion and a distal portion;
a connector disposed adjacent the distal portion of the first elongated member and adjacent the proximal portion of the second elongated member to connect the first and second elongated members; and a radiopaque marker disposed adjacent the connector for imaging the device.
2. The medical device of claim 1, wherein the connector comprises a tubular connector member disposed about the distal portion of the first elongated member and about the proximal portion of the second elongated member.
3. The medical device of claim 2, wherein the radiopaque marker is disposed within the tubular connector member, or the radiopaque marker is disposed about the distal portion of the first elongated member adjacent the connector, or the radiopaque marker is disposed about the proximal portion of the second elongated member adjacent the connector.
4. The medical device of claim 2, wherein the radiopaque marker is disposed within the tubular connector member between the distal portion of the first elongated member and the proximal portion of the second elongated member.
5. The medical device of claim 1, wherein the radiopaque marker is coupled to the connector.
6. The medical device of claim 1, further comprising one or more additional radiopaque marker disposed adjacent the connector for imaging the device.
7. The medical device of claim 1, wherein the connector comprises a tubular connector member disposed about the distal portion of the first elongated member and about the proximal portion of the second elongated member, and the radiopaque marker is disposed within the tubular connector member; and the medical device further comprises one or more additional radiopaque marker that is disposed about either the distal portion of the first elongated member adjacent the connector or disposed about the proximal portion of the second elongated member adjacent the connector.
8. The medical device of claim 1, wherein the device is a guidewire.
9. The medical device of claim 1, wherein the first elongated member comprises a first material, and the second elongated member comprises a second material different from the first material.
10. The medical device of claim 9, wherein the first material comprises a stainless steel alloy.
11. The medical device of claim 9, wherein the second material comprises a nickel-titanium alloy.
12. The medical device of claim l, wherein the device includes a connector assembly including the connector and the radiopaque marker, the connector assembly disposed adjacent the distal portion of the first elongated member and adjacent the proximal portion of the second elongate member to connect the first and second elongated members.
13. A method of manufacturing a medical device, the method comprising:
providing a first elongate member and a second elongate member, each having a proximal portion and a distal portion;
providing a connector assembly comprising a connector member and one or more radiopaque marker; and connecting the distal end of the first member and the proximal end of the second member using the connector assembly such that the one or more radiopaque marker is disposed adjacent the connector member.
14. The method of claim 13, wherein the connector member comprises a tubular connector member, and the connecting step includes disposing the connector member about the distal portion of the first elongated member and about the proximal portion of the second elongated member.

The medical device of claim 23, wherein the means for connecting comprises a connector assembly including a connector and a radiopaque marker, and the means for imaging comprises the radiopaque marker of the connector assembly, the connector assembly disposed adjacent the distal portion of the first elongated member and adjacent the proximal portion of the second elongate member to connect the first and second elongated members.
25. The medical device of claim 24, wherein the connector comprises a tubular connector member disposed about the distal portion of the first elongated member and about the proximal portion of the second elongated member, and the radiopaque marker is disposed within the tubular connector member, or the radiopaque marker is disposed about the distal portion of the first elongated member adjacent the connector, or the radiopaque marker is disposed about the proximal portion of the second elongated member adjacent the connector.
26. The medical device of claim 24, wherein the connector assembly further includes one or more additional radiopaque marker disposed within the tubular connector member, or disposed about the distal portion of the first elongated member adjacent the connector, or disposed about the proximal portion of the second elongated member adjacent the connector.
27. The medical device of claim 23, wherein the device is a guidewire.
28. The medical device of claim 23, wherein the first elongated member comprises a first material, and the second elongated member comprises a second material different from the first material, wherein the first material may optionally comprise stainless steel, and the second material may optionally comprise a nickel-titanium alloy.
