Abstract

Arrangements are disclosed in which proximal portions of a marker wire are effectively secured. In one embodiment, a proximal portion of the marker wire is positioned inside a tubular member that allows for slidable movement of the marker wire within the tubular member. In some embodiments, a proximal portion of the marker wire is coupled to a spring member. Some embodiments also disclose a movement-resisting member having flaps that contact the surface of the marker wire and resist movement of the marker wire in one or more directions.

First claim

What is claimed is:

1. A kit, comprising:
a packaging member retaining:
a marker wire having a distal end region arranged for securement in a desired location inside a patient and a proximal end region having a proximal wire portion; and
a wire-retaining member arranged to be secured to the patient and receive said proximal wire portion;
wherein said wire-retaining member slidably couples said proximal wire portion of said marker wire to the patient; and wherein the marker wire has withdrawal-resisting member at the distal end region.

2. The kit of claim 1 , wherein:
said wire-retaining member confines movement of said marker wire to a direction substantially along the length of said proximal wire portion.

3. The kit of claim 1 , further comprising:
an adhesive member on said wire-retaining member arranged to couple said wire-retaining member to the body of a patient.

4. The kit of claim 3 , wherein the adhesive member is located between the wire-retaining member and the patient when the wire-retaining member is secured to the patient.

5. The kit of claim 1 , wherein:
said wire-retaining member comprises a tube defining an internal lumen arranged to receive said proximal wire portion.

6. The kit of claim 5 , wherein:
said tube comprises a curved portion and a first opening communicating with said internal lumen and arranged to receive said marker wire.

7. The kit of claim 1 , wherein a length of the wire-retaining member defines a loop.

8. A marker wire retaining device, comprising:
a wire-retaining member arranged to be secured to a patient and defining a wire receiving region arranged to receive a proximal wire portion of a marker wire; and
an adhesive member arranged to couple said wire-retaining member to the patient, the adhesive member being located between the wire-retaining member and the patient when the wire-retaining member is secured to the patient and a marker wire having a withdrawal-resisting member at a distal end region arranged for securement in a desired location inside a patient and a proximal end region having a proximal wire portion;
wherein said wire-retaining member slidably couples said proximal wire portion to the patient.

9. The marker wire retaining device of claim 8 , wherein:
said wire receiving region defines a path having a curved portion.

10. The method of claim 9 , wherein said wire-retaining member comprises a ribbon shape.

11. The method of claim 9 , wherein said wire-retaining member comprises a coil shape.

12. The marker wire retaining device of claim 8 , wherein a length of the wire-retaining member defines a loop.

13. A method, comprising:
advancing a marker wire through a penetration site in skin of a patient to a desired location within the patient such that a distal end region of the marker wire secures in the desired location and said marker wire extends from the desired location proximally through the skin of the patient to a proximal end region having a proximal wire portion;
inserting said proximal wire portion of said marker wire into a wire-retaining member;
advancing said wire-retaining member towards the penetration site and not advancing said wire-retaining member through said penetration site; and
securing said wire-retaining member to the skin of the patient; wherein the distal end region of the marker wire is a arranged for securement in the desired location inside the patient; wherein the wire-retaining member is arranged to be secured to the patient and receive said proximal wire portion to slidably couple said proximal wire portion of said marker wire to the patient; and wherein the marker wire has a withdrawal-resisting member at the distal end region.

14. The method of claim 13 , wherein securing said wire-retaining member includes adhesively securing said wire-retaining member.

15. A marker wire retaining device, comprising:
a wire-retaining member including an elongate tube having a distal portion, a proximal portion, and a curved portion positioned between said distal portion and said proximal portion;
said elongate tube defining an inner lumen that extends from said distal portion, through said curved portion, and into said proximal portion;
wherein said distal portion and said proximal portion cross one another in a coincident region; and
wherein said distal portion defines a groove arranged to receive said proximal portion in said coincident region so as to decrease the height profile of the device in the coincident region.

16. The marker wire retaining device of claim 15 , wherein said inner lumen of said first portion communicates with said inner lumen of said second portion in said coincident region.
