TREATMENT OF A RUPTURE OF A BODY COMPONENT

Abstract

A fibrin adhesive for use in the minimally-invasive treatment of a rupture of a body component formed by hard connective tissue adhesively bonds to that body component. A suitable treatment method features locating the rupture, providing the fibrin adhesive, and supplying the fibrin adhesive at the body component to be treated.

Claims

1. A method comprising carrying out minimally-invasive treatment of a patient's ruptured body component, said body component being made of hard connective tissue, wherein treating said ruptured body component comprises using a fibrin adhesive adhesively bonding with the body component.

2. The method of claim 1, further comprising selecting the body component to be a meniscus.

3. The method of claim 1, further comprising partially filling a tear in said body component with said fibrin adhesive.

4. The method of claim 1, further comprising providing said fibrin adhesive as a liquid and injecting said liquid into said body component using a cannula.

5. The method of claim 1, further comprising, using an imaging system, at least temporarily locating said body component during said treatment.

6. The method of claim 1, further comprising applying a marking to said patient's skin, said marking serving as a zero point of a coordinate system, and injecting said fibrin adhesive is performed on the basis of said coordinate system.

7. The method of claim 6, further comprising defining a factor on the basis of said coordinate system, said factor being selected from the group consisting of a three-dimensional penetration angle of a cannula used for the injection, a penetration depth of said cannula, and a penetration point of said cannula.

8. The method of claim 1, further comprising rendering said body component immovable for a predetermined duration following injection of said fibrin adhesive.

9. The method of claim 1, further comprising obtaining said fibrin adhesive by mixing together a first component and a second component, wherein said first component comprises human fibrinogen having a concentration in the range of 80 mg/ml to 100 mg/ml], aprotinin having a concentration in the range of 2800 KIE/ml to 3200 KIE/ml, and polysorbate 80 having a concentration in the range of 0.6 mg/ml to 1.9 mg/ml and wherein said second component comprises human thrombin having a concentration in the range of 400 I.E./ml to 600 I.E./ml, and calcium chloride having a concentration in the range of 35 ?mol/ml to 45 ?mol/ml.

10. The method of claim 2, further comprising using between 1 milliliter and four milliliters of said fibrin adhesive to treat said damaged meniscus.

Description

BRIEF DESCRIPTION OF THE DRAWING

[0065] The invention and the technical environment will be explained in greater detail hereafter on the basis of the FIGURE. The FIGURE shows a particularly preferred embodiment. However, the invention is not restricted to this illustrated embodiment. In particular, the FIGURE and in particular the illustrated size ratios are only schematic.

[0066] FIG. 1 shows a schematic illustration of the treatment of a rupture of a body component.

DETAILED DESCRIPTION

[0067] FIG. 1 shows a patient 1 in an open magnetic resonance tomograph 3 having an excitation coil 4 that is placed around the knee of the patient 1. The main coil of the tomograph 3 is omitted for clarity. In the example, shown the tomograph 3 displays a body component 2 to be treated. The body component 2 is one formed by hard connective tissue. In the illustrated example, the body component 2 is a meniscus 12.

[0068] A rupture of the meniscus 12 is treated in a minimally-invasive manner by adhesively bonding the meniscus 12 using a fibrin adhesive. To carry this out, the open magnetic resonance tomograph 3 is used for locating the meniscus 12. The fibrin adhesive is then supplied, for example, as a solution. A useful method for providing the solution is to inject the solution into the meniscus 12 using an injection device 13 having at least one cannula 5. A particularly precise injection of the fibrin adhesive can be carried out by a coordinate system 9 having a first axis 7 and a second axis 8 perpendicular to the first axis 7. A marking 10 on the patient's skin 11 indicates the coordinate origin 6 of the coordinate system 9.

[0069] A rupture of a body component 2, for example, a meniscus 12, can be treated particularly well by adhesive bonding using fibrin adhesive. The foregoing minimally-invasive intervention permits such treatment with particularly low risk and a particularly short rehabilitation phase.
