Abstract

A guide wire arrangement, a strip arrangement, a method of forming a guide wire arrangement, and a method of forming a strip arrangement are provided. The guide wire arrangement includes a strip; a sensor being disposed on a first portion of the strip; a chip being disposed next to the sensor on a second portion of the strip, wherein the second portion of the strip is next to the first portion of the strip; wherein the strip is folded at a folding point between the first portion of the strip and the second portion of the strip such that the first portion of the strip and the second portion of the strip form a stack of strip portions.

Claims

1. A guide wire arrangement, comprising:

a strip;

a sensor being disposed on a first portion of the strip;

a chip being disposed next to the sensor on a second portion of the strip, wherein the second portion of the strip is next to the first portion of the strip;

wherein the strip is folded at a folding point between the first portion of the strip and the second portion of the strip such that the first portion of the strip and the second portion of the strip form a stack of strip portions.

2. The guide wire arrangement of claim 1,

wherein the strip is folded at the folding point such that the sensor faces away from the second portion of the strip and the chip faces away from the first portion of the strip.

3. The guide wire arrangement of claim 1,

wherein the strip is folded at the folding point by about 175 degrees to about 185 degrees.

4. The guide wire arrangement of claim 1,

wherein the strip is folded at a further folding point next to the chip and at the opposite side of the chip than the folding point such that the stack of strip portions is between the folding point and the further folding point.

5. The guide wire arrangement of claim 4,

wherein the strip is folded at the further folding point by about 85 degrees to about 95 degrees.

6. The guide wire arrangement of claim 1,

wherein the strip comprises:

a first isolation layer providing a first surface of the strip;

a second isolation layer providing a second surface of the strip;

a metal layer disposed between the first and second isolation layers;

wherein portions of the metal layer are uncovered by the first isolation layer to form metal contact pads.

9. The guide wire arrangement of claim 6,

wherein the sensor and the chip are disposed on the uncovered portions of the metal layer for electrically connecting the strip.

10. The guide wire arrangement of claim 6,

wherein the strip comprises at least one through-hole formed through the at least one metal contact pad and the second isolation layer.

11. The guide wire arrangement of claim 10, further comprising:

at least one first wire being disposed on the second surface of the strip and attached to the at least one metal contact pad via the through-hole;

at least one second wire being disposed on the first surface of the strip and attached to another metal contact pad.

12. The guide wire arrangement of claim 11,

wherein the at least one first wire extends through the through-hole.

14. The guide wire arrangement of claim 11,

wherein the at least one first wire and the at least one second wire are attached to the corresponding metal contact pads using conductive glue or solder material.

16. The guide wire arrangement of claim 11,

further comprising fixtures formed on the first surface and the second surface of the strip, wherein the fixtures form a guide for wire attachment to the strip.

18. The guide wire arrangement of claim 11,

further comprising a non-conductive layer being deposited on the at least one first wire and the at least one second wire.

21. The guide wire arrangement of claim 1,

wherein the sensor comprises a microelectromechanical system sensor.

22. The guide wire arrangement of claim 1,

wherein the sensor is any one of a group consisting of a force sensor, a pressure sensor, a temperature sensor, an acceleration sensor, an angular velocity sensor, an electronic compass, and an ultrasound sensor.

24. The guide wire arrangement of claim 1,

wherein the folded areas of the strip are secured using epoxy.

25. The guide wire arrangement of claim 1,

further comprising a housing, wherein a part of or whole of the strip is received in the housing.

27. The guide wire arrangement of claim 1,

wherein the guide wire arrangement is a minimally invasive intra-vascular medical device.

28. A method of forming a guide wire arrangement, the method comprising:

providing a strip;

disposing a sensor on a first portion of the strip;

disposing a chip next to the sensor on a second portion of the strip, wherein the second portion of the strip is next to the first portion of the strip;

folding the strip at a folding point between the first portion of the strip and the second portion of the strip such that the first portion of the strip and the second portion of the strip form a stack of strip portions.
