Abstract
Abstract A lesion location device suitable for marking a lesion in breast tissue comprises a wire 1, of which the first portion 2 which has been bent 4 to form a second portion 3 at an obtuse or acute angle to the first portion, a 180 DEG bend 5 and a third portion 6 which extends adjacent the second portion and continues beyond the bend 4 in a direction substantially opposed to that of the second portion. The bend 4 is resiliently pivotable and forms a spring mechanism to prevent ingress of the wire once in position in the lesion. Two graduated cannulas are also provided, one 7 with a pointed end 8 and one 9 with a blunt end 10, which are suitable for the wire 1 to be passed into them.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
88 words
A device suitable for marking a site in tissue comprising a barbed wire wherein the wire consists of an elongate first portion, a second portion which forms an angle with the first portion and which is resiliently pivotable about its point of junction with the first portion, and a third portion which extends adjacent the second portion for at least part of the length of the second portion and then continues beyond the said point of junction in a direction substantially opposed to that of the second portion.
Claim 2
Independent Claim
88 words
A device suitable for marking a site in tissue comprising a barbed wire wherein the wire consists of an elongate first portion, a second portion which forms an angle with the first portion and which is resiliently pivotable about its point of junction with the first portion, and a third portion which extends adjacent the second portion for at least part of the length of the second portion and then continues beyond the said point of junction in a direction substantially opposed to that of the second portion.
Claim 3
Dependent Claim
20 words
A device according to claim 1 wherein the first portion and the second portion are integrally formed with one another.
Claim 4
Dependent Claim
17 words
A device according to claim 1 wherein the angle between the first and second portions is obtuse.
Claim 5
Dependent Claim
75 words
A device according to claim 3 wherein the first portion, the second portion and the third portion are formed from a single piece of wire, a portion of the wire having been bent through an acute angle to form the second portion, a further portion then having been bent through approximately 180° at a point spaced from the said point of junction between the first portion and the second portion to form the third portion.
Claim 6
Dependent Claim
49 words
A device according to claim 3 wherein the angle between the second portion and the first portion is between 150° and 120° and the angle between the first portion and the part of the third portion which extends beyond the said point of junction is between 30° and 60°.
Claim 7
Dependent Claim
45 words
A device according to claim 5 wherein the angle between the second portion and the first portion is substantially 135° and the angle between the first portion and the part of the third portion which extends beyond the said point of junction is substantially 45°.
Claim 8
Dependent Claim
17 words
A device according to claim 1 wherein the angle between the first and second portions is acute.
Claim 9
Dependent Claim
55 words
A device according to claim 1 wherein the point of junction between the first portion and the second portion is sufficiently resiliently pivotable to allow the second portion to form an angle as close to 180° or 0° as possible with the first portion such that the wire may be placed inside a hollow cannula.
Claim 10
Dependent Claim
17 words
A device according to claim 1 wherein the length of the second portion is substantially 8 mm.
Claim 11
Dependent Claim
16 words
A kit comprising a device according to claim 1 and a hollow cannula marked at intervals.
