FASTENING DEVICE, IMPLANT DEVICE, LOCKING METHOD, AND OPERATION METHOD

TECHNICAL FIELD OF THE INVENTION

The present invention generally relates to a fastening device for an implant device and more specifically to a fastening device for an adjustable implant device connected to an implant device feed member. The present invention also relates to methods for locking and implanting a medical implant.

TECHNICAL BACKGROUND

Implant devices are devices that are adapted for being placed in e.g. human bodies or animals, and that e.g. replace body parts that have been damaged or removed e.g. due to cancer.

In order to keep the implant device in place so that it does not move freely within e.g. a human body cavity, it is known to fasten the implant device in position using a fastening device. A known fastening device is a band type device having two ends, where a first end has a hole, and a second end has a protruding part arranged to be placed in said hole in order to lock the two ends of the band type device together after having been looped around an implant device and a body part such as an intestine, thereby fastening the implant device in place. In order for the band ends not to be separated when e.g. a person carrying the implant moves around, the protruding part is of flexible material and has a ball shaped outer end of somewhat larger cross-section than the diameter of the hole, whereby the ball shaped end is elastically deformed when pushed through the hole and regains its shape when leaving the hole, thus keeping the band ends locked to each other.

DESCRIPTION OF PREFERRED EMBODIMENTS

Briefly described, the present invention provides a solution for enabling an easy and fully, i.e. 100%, reversible way of keeping an implant in place so that it does not move freely, by providing and placing a fastening device for an implant device into e.g. a body of a patient, where the “patient” is a living creature such as e.g. a human or an animal.

The invention is now described, by way of example, with reference to the accompanying drawings, in which:

FIG. 1 shows schematically a fastening device 2 for an implant device 4 according to one exemplary embodiment of the invention. The implant device is adjustable and the fastening device 2 comprises at least two fastening sections 6, 8 (only two fastening sections are shown in the figure), where a first fastening section 6 is arranged with a through hole 10, a second fastening section 8 is arranged with a protruding part 12, and where said protruding part 12 is in place in said trough hole 10 in a fastening device locking state (for the fastening device locking state, see FIG. 2, FIG. 1 shows an unlocked fastening device state). As can be seen from the FIG. 1, the protruding part 12 on the second fastening section 8 is arranged with a trough channel 14 having an inlet 16 and an outlet 18, said through channel 14 being arranged to receive an implant device feed member 20. The implant device feed member is arranged to be a locking member and for being involved in the adjustment of the implant device by feeding at least one of a hydraulic or pneumatic fluid, electrical energy and an electrical signal to the implant device, Also, the first and second fastening members are in contact with each other when locked in the locking state. The inlet 16 and the outlet 18 are accessible from the exterior 1, 3 of the fastening device 2 in said fastening device locking state, wherein the first fastening section 6 is detachably securely locked to the second fastening section 8 when, in said fastening device locking state, said implant device feed member 20 is in place in the trough channel 14 and protrudes from both the inlet 16 and the outlet 18 of said trough channel 14. The fastening device is adapted to be reversible in two steps, involving to remove said implant device feed member from the through channel and thereafter detaching the first fastening section from the second fastening section.

It is preferred that the implant feed device member 20 is arranged to be in contact with the first fastening section, when locked in said locking state.

Said trough channel 14 may be of any length, i.e. if the protruding part 12 is very thin, said trough channel 14 could be similar to a hole.

Said inlet 16 and outlet 18 are accessible from the exterior of the fastening device 2 in said fastening device locking state, i.e. said inlet 16 and/or outlet 18 may be accessible from one or more sides of the fastening device 2 in said fastening device locking state, e.g. from one of or from some of the following sides: the outer side, the inner side, or any other side not belonging to the outer side and the inner side, of the fastening device 2, see e.g. FIG. 8 showing an embodiment where said inlet 16 is accessible from the exterior of the fastening device 2 by being accessible from the inner side 1 of the fastening device 2 and where said outlet 18 is accessible from the exterior of the fastening device 2 by being accessible from the outer side 3 of the fastening device 2.

The first fastening section 6 of the fastening device 2, and the second fastening section 8 of the fastening device 2, may have any cross-section, e.g. a cylindrical, tubular or band shaped cross-section, where a band shaped cross-section is shown in the figure for both the first fastening section 6 and the second fastening section 8, and where the cross-section of the first fastening section 6 does not have to be the same as the cross-section of the second fastening section 8.

The first and the second fastening sections 6, 8 may be arranged on the same fastening unit or on separate fastening units, where an embodiment where the first and the second fastening sections 6, 8 are arranged on the same fastening unit 22, is shown in the figure.

None or at least one of the fastening units may be attached to the implant device 4, and the implant device feed member 20 may be or not be attached to a fastening unit, where an embodiment where no fastening unit 22 is attached to the implant device 4 by attachment means, e.g. by chemical or mechanical means such as adhesive or suturing, and where the implant device feed member 20 is not attached to a fastening unit 22, is shown in the figure.

The inlet 16 and the outlet 18 of the trough channel 14 arranged in the protruding part 12 on the second fastening section 8 may be arranged on the same side of the first fastening section 6 in the fastening device locking state, or on different sides of the first fastening section 6 in the fastening device locking state, where an embodiment where the inlet 16 and the outlet 18 of the trough channel 14 arranged in the protruding part 12 on the second fastening section 8 is arranged on the same side of the first fastening section 6 in the fastening device locking state, is shown in the figure.

The first fastening section 6 is preferably detachably securely locked to the second fastening section 8 when said implant device feed member 20 is in place in the trough channel 14 and protrudes from both the inlet 16 and the outlet 18 of said trough channel 14, by that it is possible to remove the implant device feed member 20 from the trough channel 14, where after it is possible to detach the first fastening section 6 from the second fastening section 8, this without any substantial effort and without having to deform any parts of the fastening device 2.

The implant device feed member 20 may or may not be detachably or non-detachably attached to the implant device 4.

The implant device feed member 20 may be arranged to feed hydraulic fluid, pneumatic fluid, or electrical energy or electrical signals between the implant device 4 and a remote unit 24, e.g. that the implant device feed member 20 is arranged to feed hydraulic fluid, pneumatic fluid, or electrical energy or electrical signals to and/or from the implant device 4.

As can be seen from the figure, the implant device 4 may be arranged to be fastened around a body part or another implanted device or member 26. Said body part may e.g. be at least one of a stomach or divided part of the stomach, an intestine, a closing sphincter and other part of the food passageway. Said body part may e.g. be at least one of an urethra and other part of the urinary tract. Said body part may e.g. be a blood vessel or heart. Said body part may e.g. be a vas deferens or uterine tube.
