[0001] The invention relates to an implantation device for inserting an implant into tissue, in particular into the eyeball, according to the preamble of claim 1 .

[0002] The implant device according to the present invention is preferably adapted to insert the implant into the tissue of a patient, in particular a human or an animal. In particular, the implant device according to the present invention is adapted for intravitreal insertion or injection of the implant. In other words, the tissue is preferably the patient's eyeball or a part thereof, in particular the vitreous body or the eye chamber, the anterior chamber and / or the posterior chamber of the eye. The implant is in particular an intravitreal implant and / or an implant for releasing a medicament or a drug or an active substance to the eye, in particular the vitreous body, over a longer time span (such as weeks or months, in particular a time span of up to 3 years). Background Art

[0003] Generally speaking, implantation devices for inserting implants into the eyeball are known in the art.

[0004] US2013 / 0158561A1 relates to an assembly for implanting an ocular implant into a mammalian eye. The assembly comprises a cannula having a curved distal end, an injector mechanism coupled to the cannula for linearly moving one or more implant segments in the cannula toward the curved distal end, and a rotator mechanism for rotating the cannula about its longitudinal axis. The device can be actuated by a user pressing a release button, which drives a plunger to push the implant segments along a needle with the aid of a compression spring.

[0005] US2014 / 0031833A1 relates to an intraocular syringe comprising an injection and washing body, one end of which is provided with an open cone, and a piston is provided in the body. A transparent implant holder having an inner cavity is aligned with the open end of the cone. Injection is performed through a needle with a bevel at the distal end. A plunger is fastened to the piston and can slide in the holder cavity and the needle cavity for injecting a solid intraocular implant into the eye. The plunger can be moved by pushing against a thumb pad arranged at the end of the plunger.

[0006] WO2009 / 061988A1 relates to an ocular implant device, which includes a housing having a longitudinal axis, a needle configured to receive an implant, and a plunger and a rod operably coupled together. The plunger and the rod are arranged in the housing and are movable in translation along the longitudinal axis of the housing. The rod is configured to be receivable in at least a portion of the needle so that the rod can move the implant through. The actuator is operably engaged with the plunger so that the actuator moves in a direction aligned with the longitudinal axis of the housing to cause the plunger rod to move in translation along the longitudinal axis of the housing so as to deliver the implant to a target position through the needle.

[0007] WO2013 / 120033A1 relates to a syringe device for delivering an implant. The device comprises a retracting element, a trocar and a plunger. The device may include a latch which, when actuated by a user, causes the retracting element to move the trocar away from a delivery site, allowing the plunger to eject the implant into the site. The device may be configured for intraocular drug delivery.

[0008] WO2016 / 040605A1 relates to an injector device for delivering a payload to an eye, the injector device comprising a housing, a cannula defining a lumen and having a proximal end received in the housing and a distal end extending from the housing, a hollow needle having a distal end with a tip for piercing tissue, a shifter for moving the needle from an extended position to a retracted position, and an actuator for advancing the payload from an initial position to withdraw from the distal end of the cannula. Summary of the invention

[0009] An object of the present invention is to provide an improved implant device which is easy to use and / or simple, intuitive and / or safe to use and / or simple in structure and / or simple to manufacture and / or inexpensive.

[0010] This object is achieved by an implant device according to claim 1. Advantageous further developments are subject matter of the dependent claims.

[0011] Implantation device according to the present invention is preferably adapted to hold implant and / or insert implant into tissue of patient (such as human or animal, particularly mammal).Particularly, implantation device is adapted to insert or inject implant into eyeball, particularly in vitreous body or vitreous cavity, anterior chamber of the eye and / or posterior chamber of the eye.

[0012] The implant device has a housing and a plunger, which is preferably at least partially received in the housing. The implant device preferably has a cannula or a hollow needle and / or a connecting device for connecting the cannula or the hollow needle to the housing. The needle and / or the connecting device are preferably arranged at an axial end of the housing. The plunger is axially movable relative to the housing, the needle and / or the connecting device. The hollow needle is generally simply indicated as "needle" hereinafter.

[0013] According to a first aspect of the invention, the implant device preferably has an actuator for moving the plunger relative to the housing, the actuator having or forming a lever mechanism. This allows simple and convenient use of the implant device, in particular one-handed use, wherein a simple construction of the implant device is simultaneously achieved.

[0014] According to another aspect, which may also be realized independently, the hollow needle is preferably freely rotatable about the longitudinal axis and relative to the housing. In other words, it is preferred that the needle can be positioned in any rotational position and / or that the needle is not limited to discrete rotational positions. In this way, the user can freely control or adjust the rotational angle between the needle and the housing and / or the actuator, allowing optimal control of the injection of the implant.

[0015] According to another aspect, which can also be realized independently, the implantation device preferably has a holding device for holding the implant received in the needle in position. By means of the holding device, the implant can be prevented from accidentally falling out of the needle before being injected into the tissue or the eyeball. Therefore, the use of the implantation device becomes easier and safer.

[0016] According to another aspect, which can also be realized independently, the implant device preferably has a cover configured to cover the needle, the cover comprising an implant lock for retaining the implant in the needle. In this way, the use of the implant device becomes easier and safer. The cover protects the needle against damage and protects the user from the needle. In addition, the cover maintains the sterility of the needle. By integrating the implant lock into the cap, on the one hand, it is prevented that the implant accidentally falls out of the needle before injection / insertion into the tissue or the eyeball, and on the other hand, the number of preparation steps before inserting the implant can be reduced, because the cap and the implant lock can be removed in one common step.

[0017] Preferably, the actuator has or forms a toggle joint. The toggle joint is in particular a lever mechanism of a particular type. According to the invention, the toggle joint has or consists of two rods or arms, which are connected by a joint arranged at the ends of the arms or rods. This facilitates a simple and cost-effective construction. The toggle joint allows a very precise application of the force for pushing the implant out of the needle and / or a very precise control of the position of the plunger. At the same time, the implant device, in particular the actuator or the actuating mechanism, can be manufactured very easily and is therefore cost-effective.

[0018] The actuator preferably has an arm forming a second-stage lever. The second-stage lever is in particular a lever mechanism of a particular type. In the second-stage lever, the resistance or load is between the force and the fulcrum. By means of the second-stage lever, the force required to activate the actuator is very small and the position of the plunger can be controlled very accurately. At the same time, the actuator can be manufactured very easily and is therefore cost-effective.

[0019] Preferably, the actuator has an arm with a first section and a second section. Here, the first section preferably forms a lever or rod of the toggle joint, while the second section forms the actuating section. In particular, the arm with the first section and the second section simultaneously forms a second-level lever. This facilitates simple and effortless handling or use of the implant device and at the same time allows a simple and cost-effective construction.

[0020] Preferably, the actuator has an arm which is configured and / or arranged to act directly on and / or move the plunger. The plunger is preferably moved when the actuator is actuated by the arm acting on the plunger. The movement of the plunger is in particular axial and / or towards the needle and / or the connecting device. The arm which is configured / arranged to act directly on the plunger preferably forms an arm of a toggle joint and / or is different from the arm which forms a one-sided lever and / or the arm having the first and second sections.

[0021] The actuator is preferably designed as a one-piece component. In particular, the actuator has at least two arms, which are preferably formed as a one-piece. The two arms are preferably connected by film hinges and / or solid joints. This reduces the number of parts to be produced and also reduces the number of steps required for assembling the implant device.

[0022] The actuator is preferably configured to engage with the plunger when the plunger reaches or has reached the end position. The engagement preferably generates a tactile, visual and / or audible signal. Specifically, the engagement provides a tactile, visual and / or audible feedback to the user of the implant device, which in particular signals that the end position of the plunger has been reached and / or that the implant has been inserted into the tissue or eyeball.

[0023] The plunger is preferably locked in the initial position. Alternatively or additionally, the implant device is configured in the following manner: a force threshold must be exceeded to move the plunger out of the initial position and / or towards the needle and / or the connecting device. In particular, the locking of the plunger causes a force threshold to be exceeded when moving the plunger. In this way, accidental actuation or movement of the plunger can be prevented. In addition, it has been shown that the locking or force threshold improves the ease of use of the implant device, because the user feels comfortable when the plunger does not move directly when actuated, but first has to exceed the force threshold.

[0024] The implant device preferably comprises a grip which is rotatably connected or connectable to the housing and connected or connectable to the needle in a rotationally fixed manner, in particular such that the needle can be rotated relative to the housing by rotation of the grip. This allows the needle to be adjusted / positioned in a desired rotational position relative to the housing, which in turn makes the implant device comfortable to use and allows precise control of the insertion of the implant into the tissue.

[0025] The plunger and / or housing may be arranged and / or configured such that the movement of the plunger relative to the housing is hindered by friction. This has been shown to improve ease of use, and in particular the user of the implant device receives better feedback and / or a feeling of better control over the movement of the plunger. In particular, accidental movement of the plunger and / or accidental delivery of the implant may be prevented or the risk thereof may be reduced.

[0026] Preferably, the implant device comprises an air passage between the plunger and the housing. The air passage particularly allows air to leave the implant device from the side opposite to the needle, the implant and / or the connecting device. Thus, accidental injection of air into tissue or the eyeball can be prevented.

[0027] Preferably, the implant device has at least one fastening device, preferably at least or exactly two fastening devices. The (one or more) fastening devices are particularly arranged at the (axial) end of the implant device and / or opposite to the needle and / or the connecting device. Particularly preferably, the implant device has a first fastening device for preventing the plunger from moving axially towards the needle and / or the connecting device. Alternatively or additionally, the implant device has a second fastening device for preventing the plunger from moving axially away from the needle and / or the connecting device. Thereby, an unexpected movement and / or actuation of the plunger can be prevented or hindered. This improves ease of use and safety.

[0028] The implant device preferably has a blocking device for blocking the actuation of the implant device and / or the actuator, in particular the downward pressing of the actuator and / or its first arm, preferably wherein the blocking device is additionally configured to prevent the plunger from moving towards the needle and / or the implant. This is beneficial for safety and prevents accidental actuation. Furthermore, preferably, the assembly of the implant device is facilitated.

[0029] The housing may be at least partially translucent or transparent, in particular so that the plunger or a portion thereof is visible through the housing. This enables a user of the implant device to visually control the movement of the plunger and / or provide visual feedback to the user. This allows better and more precise control of the actuation and / or insertion process.

[0030] Alternatively or additionally, the implant device or housing may have an indicator for indicating the state and / or position of the retaining device and / or the implant, which indicator is preferably visible through an opening of the implant device and / or the housing and / or the connecting device. This enables the user of the implant device to visually control the implantation process and / or provide visual feedback to the user. This allows better and more precise control of the actuation and / or insertion process.

[0031] The implant device preferably comprises a pusher for pushing the implant out of the needle. Specifically, the plunger comprises the pusher, or the pusher is arranged at the plunger or connected to the plunger. The pusher is preferably in wire form and / or made of metal, particularly steel.

[0032] The holding device is preferably designed as an elastic element, in particular a spring.

[0033] Preferably, the implantation device comprises or is adapted to receive an implant. Particularly preferably, the implant is received or receivable in a hollow needle.

[0073] In use, the needle 5 is preferably connected to the housing 3 and / or the connecting device 6. However, the implant device 1 does not necessarily include the needle 5 in the delivery state. In the delivery state, the implant device 1 can also only include the connecting device 6 so that different needles 5 can be connected to the housing 3 and / or the connecting device 6.

[0074] The needle 5 is preferably welded to the connection device 5B, in particular by a laser welding process. Preferably, the needle 5 is formed in one piece with the connection device 5B, or the connection device 5B and the needle 5 form different sections of an integral component.

[0094] The second arm 11 is preferably connected to the first arm 10, in particular at the first end 11A of the second arm 11. The second arm 11 or its first end 11A is preferably connected to the first arm 10 via a solid joint 12. The solid joint 12 is in particular configured as a film hinge. The film hinge is in particular a thin section of the actuator 8 about which the second arm 11 can pivot.

[0095] The first arm 10 of the actuator 8 preferably has a fixed end 10A and a free end 10B.

In embodiments not shown in the figures, the first arm 10 can be configured to be parallel to the housing 3 and / or positioned parallel to the housing 3, in particular in the transport state of the implant device 1 and / or for safety space.

[0101] Figure 3 Shown in a very schematic representation is a lever mechanism 9 which is realized or formed in particular by the actuator 8 .

[0102] According to a preferred aspect, the lever mechanism 9 is or comprises a toggle joint 15. In particular, the actuator 8 has or forms the toggle joint 15.

[0103] A "toggle joint" in the sense of the present disclosure is preferably a mechanism, in particular a mechanical linkage, comprising or consisting of two rods, namely a first rod and a second rod, which are coupled to each other via a joint. Figure 3, a lever mechanism 9 is shown. The toggle joint 15 comprises a first rod 15A and a second rod 15B. The rods 15A, 15B are coupled to each other by a joint 15C located specifically at the ends of the rods 15A, 15B. The first rod 15A is fixed at a fulcrum 15D and can pivot about the fulcrum 15D. The second arm 15B can in turn pivot about the joint 15C. The end of the second rod 15B opposite the joint 15C is movable along a straight line, as shown in FIG. Figure 3 Schematically shown. When a force acts on the first rod 15A, the first rod 15A pivots about the fulcrum 15D, and the second rod 15B then pivots about the joint 15C relative to the first rod 15A. At the same time, the end of the second rod 15B opposite the joint 15C moves along a straight line, in particular to Figure 3 This move is made by Figure 3 The arrows and dashed lines indicate.

[0104] The first and second levers 15 , 15B of the toggle joint 15 preferably each form a lever of the lever mechanism 9 .

[0105] In the actuator 8, preferably, the first section 10C of the first arm 10 realizes or represents the first rod 15A of the elbow joint 15, the second arm 11 realizes or represents the first rod 15B of the elbow joint 15, the solid joint 14 realizes or represents the fulcrum 15D of the elbow joint 15, and the solid joint 12 realizes or represents the joint 15C of the elbow joint 15.

[0106] In other words, preferably, the first section 10C of the first arm 10 forms the first rod 15A of the toggle joint 15 and the second arm 11 forms the second rod 15B of the toggle joint 15 .

[0107] According to another preferred aspect, the lever mechanism 9 is or comprises a second-stage lever 16. In particular, the actuator 8 has or forms the second-stage lever 16.

[0108] A "second class lever" within the meaning of the present invention is a lever in which, in particular, a resistance or a load is located between the working force and the fulcrum. Figure 3 1 and 2. The second stage lever 16 with the fulcrum 16A is specifically shown. The fulcrum 16A is located at the fixed end of the second stage lever. Specifically, the fulcrum 16A is formed by and / or is equivalent to the fulcrum 15D of the toggle joint 15. The resistance or load is specifically formed by the second rod 15B of the toggle joint 15.

[0109] The second-stage lever 16 preferably forms the lever of the lever mechanism 9 .

[0110] The first arm 10 of the actuator 8 preferably implements or forms the second stage lever 16. Thus, preferably, the force with which the user actuates the actuator 8 in the second section 10D represents the effort and the resistance of the second arm 11 acting on the first arm represents the resistance or load of the second stage lever 16.

[0111] exist Figures 1 to 6 In the first embodiment shown in , the lever mechanism 9 includes both the toggle joint 15 and the second-stage lever 16. Specifically, the actuator 8 includes or forms both the toggle joint 15 and the second-stage lever 16. Therein, the first arm 10 preferably forms the second-stage lever 16, while the first section 10A forms the first rod 15A of the toggle joint 15, and the second arm 11 forms the second rod 15B of the toggle joint 15. In addition, the solid hinge 12 preferably forms the joint 15C of the toggle joint 15, and the solid hinge 14 preferably forms the fulcrum 15D, 16A of the toggle joint 15 and / or the second-stage lever 16.

[0112] Next, we will combine Figure 4 , Figure 5 and Figure 6 The actuation and / or movement sequence of the implant device 1 according to the first embodiment is described in detail. Figure 4 In FIG. 1 , the implant device 1 is shown in an unactuated initial position. Figure 5 The implant device 1 is shown during actuation and / or in an intermediate position. Figure 6 The implant device 1 is shown in a final position and / or after actuation and / or ejection of the implant 2 .

[0113] In the initial position, the actuator 8, in particular its first arm 10, preferably protrudes from the housing 3 and / or is inclined relative to the housing 3. The second end 11B of the second arm 11 preferably contacts the plunger 4. In particular, the second end 11B rests against the stopper 17 of the plunger 4.

[0114] The stop 17 is preferably formed by an extension of the plunger 4 transversely (in particular perpendicularly) to the longitudinal axis A (in particular an undercut).

[0115] exist Figure 5 , the actuator 8 and / or the implant device 1 are in an intermediate position, wherein the actuator 8 has been (partially) actuated, in particular by pressing the first arm 10, in particular the second section 13D thereof. By actuation, the first arm 10 has been moved to or pressed downwards towards the housing 3. Via the solid joint 12 and / or the second arm 11, the force exerted on the first arm 10 during actuation is transmitted to the plunger 4 by the second arm 11 being placed against the stop 17, in particular causing the plunger 4 to move towards the needle 5. By the movement of the plunger 4, the pusher 7 is also moved and pushes against the implant 2 received in the needle 5.

[0116] exist Figure 6 In the final position, the actuator 8 has been fully actuated and / or pressed downward. Accordingly, the plunger 4 has moved further, in particular to the final position. In the final position, the plunger 4 is preferably placed against the stopper 18 of the housing 3. In addition, in the final position, the implant 2 has preferably been pushed out of the needle 5 by the pusher 7.

[0117] The actuator 8 preferably has coupling means 20 for coupling the actuator 8 to the plunger 4. Preferably, the plunger 4 has coupling means 21 corresponding to or complementary to the coupling means 20 of the actuator 8.

[0118] The coupling means 20 , 21 of the actuator 8 and the plunger 4 preferably form different sections of a coupling mechanism for coupling the actuator 8 to the plunger 4 .

[0119] The coupling mechanism and / or coupling device 20, 21 is preferably configured to secure or lock the actuator 8 and / or the plunger 4 in a final position and / or after insertion of the implant 2, in particular by latching.

[0120] Preferably, the coupling device 20 of the actuator 8 is arranged at the second arm 11 and / or the second arm 11 comprises the coupling device 20. In particular, the coupling device 20 is arranged at the second arm 11 laterally.

[0121] Particularly preferably, the coupling means 20, 21 of the actuator 8 and the plunger 4 are configured as or form a latching mechanism. Specifically, the coupling means 20 of the actuator 8 has or is formed by one or more latching cams, and the coupling means 21 of the plunger 4 has or is formed by one or more corresponding or complementary recesses, or vice versa.

[0122] The actuator 8 is preferably configured to snap into engagement with the plunger 4 when the plunger 4 reaches or has reached the end position. The snapping preferably generates a tactile, visual and / or audible signal, in particular a click or the like.

[0123] Particularly preferably, the snap-in and / or tactile, visual and / or acoustic signal is generated by coupling the actuator 8 to the plunger 4 via a coupling mechanism, in particular locking the coupling device 20 or the latching cam into the coupling device 21 or the recess.

[0124] In particular, in order to lock the coupling device 20 or the latching cam into the coupling device 21 or the recess, a force threshold must first be exceeded. This force threshold in particular forms a tactile signal. Furthermore, when the force threshold is exceeded, the coupling device 20 preferably snaps into the coupling device 21 with a rapid movement. Accordingly, when the coupling device 20 is locked with the coupling device 21, the first arm 10 preferably performs a rapid movement. This rapid movement of the first arm 10 is preferably a tactile and / or visual signal.

[0125] In the following, further aspects of the implant device 1, in particular its first embodiment, will be explained in more detail, again with particular reference to Figure 1 and Figure 2 .

[0126] According to a preferred aspect (which can also be realized independently), the needle 5 is freely rotatable, in particular around the longitudinal axis A and / or relative to the housing 3 and / or the actuator 8. In particular, the rotation angle or position between the needle 5 (in particular its bevel 5A) and the actuator 8 and / or the housing 3 is adjustable, in particular freely adjustable. This can increase the convenience of using the implant device 1 for the user and / or help to accurately and / or comfortably insert the implant 2 into the tissue or the eyeball.

[0127] In particular, the connecting device 6 may be particularly freely rotatable about the longitudinal axis A and / or the housing 3 .

[0128] “Freely rotatable” in the meaning of the present invention means in particular that the freely rotatable segment (in particular the needle 5 and / or the connecting device 6) is continuously rotatable around the axis A and / or positionable in any desired rotational position or angle. This is in particular in contrast to a step-by-step rotation, wherein the rotatable segment can only be positioned in defined and / or discrete rotational positions or angles.

[0129] The implant device 1 preferably comprises a gripping member 19. The gripping member 19 is preferably arranged at an axial end of the housing 3, in particular the axial end 3A comprising the connecting device 6 and / or the needle 5.

[0130] The gripping member 19 preferably has an annular shape. Preferably, the gripping member 19 is (freely) rotatable relative to the housing 3 and / or the actuator 8 and / or around the axis A. Preferably, the gripping member 19 is rotationally coupled to the needle 5 and / or one or both of the connecting means 5B, 6, in particular such that the gripping member 19 is rotationally fixed relative to the needle 5 and / or the connecting means (one or more) 5B, 6 (not relatively rotatable) and / or the needle 5 rotates together with the gripping member 19. In particular, this facilitates the rotation of the needle 5 and reduces the risk of damage to the needle 5 or injuries during rotation.

[0131] The grip 19 preferably has a larger diameter and / or cross-section than the housing 3 and / or at least partially surrounds the housing 3. Therefore, the grip 19 preferably serves as a device against which the user can place one or more fingers when actuating or using the implant device 1. This allows comfortable use and / or actuation of the implant device 1 and facilitates accurate insertion and / or injection of the implant 2.

[0132] Preferably, the grip 19 and / or the housing 3 are configured in such a way that there is friction between the grip 19 and the housing 3 when the grip 19 is rotated. In other words, the rotation of the grip 19 relative to the housing 3 and / or about the axis A is preferably hindered by friction. Particularly preferably, the amount of friction between the grip 19 and the housing 3 is selected and / or adjusted so that: on the one hand, the grip 19 can be rotated freely and easily, and on the other hand, the grip 19 is firmly held in a selected or desired rotational position as long as the user does not actively rotate it. This facilitates easy and precise adjustment of the desired rotation angle or position of the needle 5 and / or the bevel 5A.

[0133] The implant device 1 preferably has a cap 22, which is configured to cover and / or protect the needle 5. The cap 22 is preferably connectable to the connection device 5B of the needle 5, the housing 3, the connection device 6 and / or the grip 19.

[0136] The implant lock 23 is particularly fixedly connected to the cap 22. This allows the cap 22 and the implant lock 23 to be removed from the needle 5 together and / or in a single step, thereby facilitating and / or accelerating the preparation of the implant device 1 before inserting the implant 2. The cap 22 and the implant lock 23 can be formed as a one-piece component, in particular by injection molding the cap 22 and the implant lock 23. However, other solutions can also be adopted here. For example, the implant lock 23 can be glued or welded to the cap 22, or fixedly connected to the cap 22 in any other way.

[0137] The implant lock 23 is preferably insertable into the needle 5. However, as an alternative or in addition, the implant 23 can also be configured as a sleeve or the like for receiving the needle 5 and / or for being pushed through the needle 5.

[0138] The implant device 1 and / or the needle 5 and / or the connecting device 5B preferably have a retaining device 33 for retaining the implant 2 received in the needle 5 in place.

[0146] Particularly preferably, the implant device 1 is configured for releasing the implant 2 from the holding device 33 , in particular automatically, when the plunger 4 is moved towards the needle 5 and / or the implant 2 .

[0147] For example, the retaining device 33 may be configured and / or arranged in such a way that it is released and / or moved away from the implant 2 at least partially or through one or more additional sections between the retaining device 33 and the plunger 4 and / or the pusher 7 .

[0148] exist Figure 7 In the example shown, the retaining device 33 is fixed to the needle 5, which is in place between the implant 2 and the pusher 7 and / or the plunger 4. Therefore, when the plunger 4 moves toward the needle 5 and / or the implant 2, the pusher 7 preferably first contacts the retaining device 33 or the spring, thereby pushing the retaining device 33 or the spring outward and / or away from the implant 2 and / or the axis A. Thereby, the retaining device 3 is removed from the implant 2 and / or the implant 2 is released. Then, when the plunger 4 moves further toward the implant 2, the pusher 7 preferably will contact the implant 2 and, in particular, finally push the implant 2 out of the needle 5.

The holding device 33 and / or the support 34 are preferably movable relative to the needle 5 and / or the implant 2. Figure 8 In particular, the holding device 33 and / or the support 34 are movable along the axis A.

[0151] Preferably, the support 34 surrounds the needle 5 and / or is at least substantially cylindrical.

[0152] The holding device 33 is preferably fixed to the support 34 and / or movable together with the support 34 .

[0153] The holding device 33 preferably comprises a holding section 33A. The holding section 33A of the holding device 33 is preferably configured to press the implant 2 and / or to hold the implant 2 in place in the needle 5.

[0154] exist Figure 8 In the embodiment shown, the holding device 33 is preferably designed as or formed by a wire that is, in particular, curved or bent. In particular, the holding section 33A is curved or curved. Preferably, the holding section 33A has at least substantially a U-shape or a V-shape. The holding section 33A preferably comprises two legs that are angled with respect to each other, the angle between the legs preferably being 30° or more, more preferably 40° or more, in particular 50° or more, particularly preferably 60° or more.

[0155] Furthermore, the holding device 33 preferably comprises a connecting section 33B for connecting the holding device 33 to the bracket 34. The connecting section 33B is preferably arranged at least substantially parallel to the longitudinal axis A and / or is fixed to the bracket 34.

The angle between the holding section 33A and the connecting section 33B is preferably at least 90°, preferably at least 95° or at least 100°.

[0157] The needle 5 preferably comprises an opening 5D, which is in particular arranged at the side of the needle 5. The opening 5D preferably allows the retaining means 33 to at least partially reach into the needle 5 and / or to contact the implant 2, in particular to exert pressure thereon.

[0158] The implant 2 is preferably held in place by a particularly radial pressure or force exerted by the holding means 33, particularly the holding section 33A, on the implant 2. The holding section 33A is preferably arranged or arrangeable in the opening 5D.

[0159] The implant device 1 preferably comprises an indicator 35 for indicating the status and / or position of the retaining device 33 and / or the implant 2. In particular, the indicator 35 is configured for indicating whether the implant 2 is (still) fastened or held in place by the retaining device 33. The indicator 35 is preferably an optical indicator.

[0160] For example, the indicator 35 may have a specific color or several different colors to indicate the status of the implant 2, and / or the indicator 35 may indicate the status of the implant 2 and / or the retaining device 33 through numbers, graphics, symbols, text, etc.

The (one or more) openings 36 can be designed as penetrations through the connecting device 5B or the housing 3, which can also have or be formed by a window, etc. Preferably, the indicator 35 and / or the retainer 34 are visible through the opening 36 or the window.

[0162] The presence of several openings 36 notably allows the indicator 35 to be seen or read in any rotational position of the needle 5 and / or of the support 34 .

[0163] Preferably, the support 34 comprises an indicator 35 .

[0164] The plunger 4 is preferably configured to move the support 34 and / or the retaining device 33. When the implant device 1 is actuated or the plunger 4 is moved, the support 34 is preferably in contact with the plunger 4 or a part operatively connected thereto, so that the movement of the plunger 4 causes the support 34 to move along the axis A and / or toward the end of the needle 5 (i.e., toward Figure 8 By this movement of the support 34, the retaining device 33 is preferably also moved relative to the needle 5, so that the retaining device 33, in particular the retaining section 33A or its legs, slides along the edge of the opening 5D and / or is lifted from the implant 2, and the retaining device 33 or the retaining section 33A is moved out of the needle 5, so that the implant 2 is released from the retaining device 33 and / or is no longer fastened by the retaining device 33. Thereafter, the plunger 4 or the pusher 7 preferably pushes the implant 2 out of the needle 5.

[0165] The user preferably sees the movement of the retaining device 34 through the opening 36. During and / or after the movement of the retaining device 34, different sections of the retaining device 34 and / or the indicator 35 are preferably visible through the opening 36. This indicates in particular to the user whether the implant 2 is (still) held or fastened by the retaining device 33 or is not (any more) held or fastened by the retaining device 33. For example, the indicator 35 may have different colors and / or symbols, so that different colors / symbols are visible during the movement of the plunger 4 and / or the retainer 34, wherein the different colors or symbols and / or changes thereof indicate the status to the user.

[0166] exist Fig. 9 and Fig.10 In FIG. 1 , another embodiment of the holding device 33 is shown.

[0167] exist Fig. 9 and Fig.10 In the embodiment shown, the retaining device 33 is preferably in a fixed position along the axis A and / or relative to the needle 5. In other words, the retaining device 33 is preferably (axially) immovable relative to the needle 5. In particular, the retaining device 33 is fixedly or immovably connected to the needle 5 at least in the axial direction.

[0168] The implant device 1 preferably comprises a release device 37 for releasing the retaining device 33. The release device 37 is preferably at least partially arranged within the housing 3 or its interior 3C and / or the connecting device 5B.

[0169] The release device 37 is preferably movable within the housing 3, the connection device 5B and / or the interior 3C and / or relative to the needle 5 and / or the retaining device 33. In particular, the release device 37 is movable along the axis A.

[0170] The release device 37 preferably includes an indicator 35. The indicator 35 of the release device 37 is preferably designed to be combined with the front Figure 8 The illustrated embodiment depicts an indicator 35 of a retainer 34 .

[0171] In particular, the release device 37 is configured for releasing the retaining device 33 from the implant 2 , in particular by a relative movement between the retaining device 33 and the release device 37 and / or by lifting the retaining device 33 or moving the retaining device 33 away from the needle 5 and / or the implant 2 .

[0172] The release device 37 preferably has a contact area 37A for contacting the retaining device 33 or a section thereof, in particular the contact section 33C. The contact area 37 is preferably arranged at an axial end of the release device 37 and / or is inclined relative to the needle 5 and / or the axis A. In particular, the contact area 37 is at least substantially conical or similar in shape.

[0173] The holding device 33 preferably comprises a contact section 33C, which is particularly configured to be in contact with the contact area 37A of the release device 37. The contact section 33C is preferably arranged transversely, in particular vertically and / or radially to the needle 5 and / or the axis A. The contact section 33C is particularly arranged at an end of the holding device 33 and / or forms an end section of the holding device 33.

[0174] exist Fig. 9 and Fig.10In the embodiment shown, the holding device 33 preferably further includes a holding section 33A. The holding section 33A is preferably designed according to Figure 8 The holding section 33A of the holding device 33 of the embodiment shown. Therefore, the above description about the holding section 33A also applies to Fig. 9 and Fig.10 The holding section 33A of the illustrated embodiment.

[0175] Furthermore, the holding device 33 preferably comprises a connecting section 33B. The holding device 33 or the connecting section 33B is preferably connected to the needle 5, in particular such that the holding device 33 is in a fixed axial position relative to the needle 5. Preferably, the connecting section 33B comprises two straight sections, preferably at an angle to each other or formed thereby.

[0176] The holding section 33A is preferably arranged between the contact section 33C and the connecting section 33B.

[0177] The contact section 33C preferably extends transversely, in particular perpendicularly to a plane in which the holding section 33A and / or the connecting section 33B and / or the holding section 33A and the connecting section 33B lie.

[0178] The release device 37 preferably comprises a recess 37B for receiving the retaining device 33, in particular the connecting section 33B and / or the retaining section 33A. The recess 37B is preferably a slot or a cutout in the release device 37. Preferably, the recess 37B extends parallel to the axis A.

[0179] The plunger 4 is preferably configured to move the release device 37, in particular relative to the holding device 33 and / or the needle 5. When the implant device 1 is actuated and / or the plunger 4 is moved, the plunger 4 or a part operatively connected thereto preferably contacts the release device 37, so that the movement of the plunger 4 causes the release device 37 to move along the axis A and / or toward the needle 5 (i.e., to the position of the needle 5). Fig. 9 The release device 37 moves to the left side in the figure (as shown by the arrow). By this movement of the release device 37, the contact area 37A contacts the holding device 33, in particular the contact section 33C. When the plunger 4 and / or the release device 37 moves further, the contact section 33C slides along the moving contact area 37A, causing the holding section 33A and the contact section 33C to be lifted and / or moved away from the needle 5 and / or the implant 2. As a result, the implant 2 is released from the holding device 33 or the holding section 33A.

[0180] The release device 37 preferably comprises a spring section 37C. The spring section 37C is preferably formed integrally with the release device 37 or as one section.

[0181] The release device 37 and / or the spring section 37C are preferably formed from a flexible and / or elastic material, in particular plastic.

[0182] The spring section 37C is particularly compressible, particularly preferably along the axis A. As a result, the overall length or effective length of the release device 37, particularly along the axial direction and / or along the axis A, can be reduced. This allows in particular to first move the release device 37 relative to the retaining device 33 using the plunger 4, thereby releasing the implant 2, and subsequently to push the implant 2 out of the needle 5 by the pusher 7.

[0183] The spring section 37C preferably comprises or is formed by a preferably at least substantially hollow cylindrical skeleton having a plurality of openings or penetrations 37D. The spring section 37C or the skeleton preferably extends along the axis A and / or surrounds the axis A.

[0184] The spring section 37C or skeleton is preferably compressible due to the plurality of openings or penetrations 37D.

[0185] Specifically, when the plunger 4 moves toward the release device 37, the retaining device 33 is lifted, in particular from the implant 2, as described above. Then, the release device 37 preferably contacts the wall of the inner portion 3C, so that the release device 37 is not further movable. At this time, when the plunger 4 moves further toward the release device 37, the spring section 37C is preferably compressed, thereby allowing the plunger 4 to move further. Then, the pusher 7 will contact the implant 2 and eventually push the implant 2 out of the needle 5.

[0186] As an alternative or in addition to the retaining means 33, the implant 2 can be retained in the needle 5 and / or in place by a particularly viscous fluid, paste or ointment. For example, the implant 2 can be retained in the needle 5 and / or in place by vaseline / petroleum jelly.

[0187] Preferably the implant device 1 is configured in such a way that a force threshold must be exceeded to move the plunger 4 out of the initial position and / or towards the needle 5 and / or the connecting device 6. In particular, the plunger 4 is locked in the initial position, preferably in order to provide the force threshold.

[0188] Therefore, the implant device 1 preferably comprises a latching mechanism 26 for locking the plunger 4 in the initial position and / or the final position. Preferably, the latching mechanism 26 is configured to lock the plunger 4 in both the initial position and the final position.

[0189] The latch mechanism 26 preferably has one or more notches 16A and one or more cams 26B, which in particular correspond to or are complementary to the notches 26A. Preferably, the plunger 4 comprises the one or more notches 26A, and the housing 3 and / or the actuator 8 comprises the one or more cams 26B, or vice versa. The (one or more) cams / cams 26B preferably protrude from the wall 3D of the housing 3 and / or protrude into the interior 3C.

[0190] Preferably, the latch mechanism 26 comprises a notch 26A and a corresponding or complementary cam 26B, which is configured to lock the plunger 3 in the initial position. Alternatively or additionally, the locking mechanism 26 preferably comprises a notch 26A and a corresponding or complementary cam 26B, which is configured to lock the plunger 3 in the end position.

[0191] Particularly preferably, the locking mechanism 26 comprises two notches 26A and two cams 26B, wherein the notches 26A and the cams 26B form two pairs, each pair comprising one of the notches 26A and one of the cams 26B. One pair is preferably configured to lock the plunger 4 in the initial position, while the other pair is preferably configured to lock the plunger 4 in the end position.

[0192] The force threshold that needs to be exceeded to move the plunger 4 out of the initial position is caused in particular by the locking of the latch mechanism 26 and / or the cam 26B when the plunger 4 is in the initial position.

[0193] The actuator 8, in particular the connecting section 13, preferably has one or more protrusions 13A. The protrusions 13A are preferably configured to fix the actuator 8, in particular the connecting section 13, to the housing 3, in particular in an interlocking manner. The protrusions 13A preferably reach through the wall 3D and / or may be arranged or arranged in a penetration 3E of the housing 3, which is configured to receive the protrusions 13A and / or fix the actuator 8, in particular the connecting section 13, to the housing 3. The protection piece 13A is in particular designed as a bolt extending from the connecting section 13.

[0194] exist Figures 4 to 6 In the embodiment particularly shown in FIG. 8 , each of the one or more cams 26B is preferably formed by a projection 13A of the actuator 8 , in particular of the connecting section 13 .

[0195] Thus, the projection 13A preferably has a dual function, on the one hand, fixing the actuator 8 to the housing 3, and on the other hand, forming part of the latching mechanism 26, in particular the cam 26B, for latching the plunger 4 in the initial position. In this way, a simple construction of the implant device 1 is achieved, and the number of sections is reduced.

[0196] However, it is not mandatory that the actuator 8 comprises or forms the cam 26B and / or the protrusion 13A forms the cam 26B of the latching mechanism 26. For example, the protrusion 13A may also be a protrusion 13A of the wall 3D itself.

[0197] The implant device 1 preferably comprises an air channel 27. The air channel 27 is particularly arranged between the plunger 4 and the housing 3, in particular the inner wall 3D. The air channel 27 is preferably configured to allow passage of air between the plunger 4 and the housing 3, in particular the inner wall 3D, and / or to allow air to be discharged from the implant device 1 or the housing 3. The air channel preferably extends along and / or at least parallel to the axis A. The air channel 27 is particularly configured to avoid an increase in pressure in the implant device 1, in particular an increase in pressure in the housing 3 and / or in the interior 3C, when the plunger 4 is moved towards the axial end 3A of the housing and / or the needle 5 and / or the connecting device 6.

[0198] The air channel 27 is formed in particular by the distance and / or free space between the plunger 4 and the inner wall 3D of the housing 3, in particular (radially) around the plunger 4. The air channel 27 is therefore preferably at least substantially annular.

[0199] The implant device 1, in particular the plunger 4 and / or the housing 3, is arranged and / or configured in such a way that a movement of the plunger 4 relative to the housing 3 is frictionally blocked. This can be achieved in various ways.

[0200] For example, in the first embodiment, the protrusion 13A of the actuator 8 or the connecting section 13 may be configured to contact the plunger 4 during the movement from the initial position to the final position, thereby generating friction. However, other solutions may also be adopted here. For example, the plunger 4 and / or the housing 3, in particular the inner wall 3D, may include one or more protrusions as an alternative or in addition to the protrusion 13A of the actuator 8 or the connecting section 13.

[0201] The implant device 1 preferably comprises an obstruction device 38 for preventing or blocking a (particularly accidental) actuation of the implant device 1 and / or the actuator 8 , in particular a downward pressing of the actuator 8 and / or the first arm 10 .

[0202] The blocking means 38 is preferably configured to prevent a movement of the pusher 7 and / or the plunger 4 towards the needle 5 and / or the implant 2 , in particular in addition to preventing an actuation of the actuator 8 .

[0203] Preferably, the obstruction device 38 can be arranged or at least partially arranged in the implant device 1 and / or the housing 3 and / or the interior 3C and / or between the plunger 4 and the connecting device 5B, in particular in the axial direction. In addition, the obstruction device 38 is preferably removable from the implant device 1 and / or the housing 3 and / or the interior 3C. The implant device 1 and / or the housing 3 preferably comprises an opening, wherein the obstruction device 28 is at least partially arranged or can be arranged.

[0204] The obstruction device 38 is preferably arranged or arrangeable between the actuator 8 (especially the first arm 10) and the housing 3 and / or the connecting device 5B, especially so that the obstruction device 38 prevents or obstructs the actuator 8 and / or the first arm 10 from being actuated or pressed downward.

[0205] The blocking device 38 is preferably connectable to the connecting device 5B, for example by an interlocking connection and / or a force fit. This facilitates assembly of the implant device, as will be described in further detail below.

[0206] The connection between the impeding device 38 and the connecting device 5B is preferably releasable, in particular without destroying or damaging the impeding device 38 and the connecting device 5B.

[0207] Preferably, the impeding means 38 has a groove 39. The groove 39 is preferably configured to receive and / or surround the pusher 7 and / or the needle 5.

[0208] exist Fig.11 and Fig.12 In the embodiment shown, wherein the implant device 1 comprises an obstruction device 38, the pusher 7 and the plunger 4 are preferably separate components. Specifically, the pusher 7 and the plunger 4 are connectable to each other by interlocking. To this end, the pusher 7 and the plunger 4 preferably have interlocking sections 40A, 40B, which correspond to each other.

[0209] Preferably, the pusher 7 comprises or forms an interlocking section 40A, and the plunger 4 comprises or forms an interlocking section 40B. The interlocking sections preferably form a male section and a female section of an interlocking connection. Particularly preferably, the interlocking section 40A forms a male section, and the interlocking section 40B forms a female section of an interlocking connection. However, other solutions can also be adopted here.

[0210] In the embodiment shown, the interlocking section 40A of the pusher 7 is formed by a section that is at least substantially conical. The conical section preferably widens toward the side or end of the pusher 7 facing the implant 2, and / or is received or adapted to be received in the needle 5. Preferably, the interlocking section 40A has an undercut 40C, which is preferably transverse to (particularly perpendicular to) the axis A, and / or is configured to interlock with the interlocking section 40B of the plunger 4.

[0211] The interlocking section 40A and / or the tapered section and / or the undercut 40C preferably have a larger cross-section than the groove 39, in particular so that the interlocking section 40A cannot be placed in the groove 39, and / or when the pusher 7 is received in the groove 39, the movement of the pusher 7 toward the groove 39 is hindered in the following way: the interlocking section 40A and / or the tapered section and / or the undercut 40C contact the obstruction device 38 or are blocked by it and / or do not fit into the groove 39.

[0212] The interlocking section 40B is preferably configured to receive the interlocking section 40A and / or is complementary in shape to the interlocking section 40A. Specifically, the interlocking section 40B is tapered and preferably widens toward the pusher 7, and is in particular a complementary tapered shape. Preferably, the interlocking section 40B has an undercut 40D, which is preferably transverse to, in particular perpendicular to, the axis A and / or is configured to interlock with the interlocking section 40A (in particular the undercut 40C) of the pusher 7.

[0213] The interlocking sections 40A, 40B are preferably configured to be non-releasably or irreversibly connected and / or cannot be separated from each other after being connected.

[0214] One problem in the assembly of the implant device 1 is to connect all the segments without damaging the implant 2 and / or other segments and without accidentally moving the implant 2 inside the needle 5 or even pushing the implant 2 out of the needle 5. The assembly of the implant device 1 is particularly facilitated by the combination of the implant device 1 with the blocking device 38 and the configuration of the pusher 7 and the plunger 4 as two separate parts that can be connected to each other.

[0215] The assembly of the implant device 1 and the blocking device 28 is preferably as follows:

[0216] The implant 2 is placed in the needle 5. Before or after the implant 2 is placed in the needle 5, the cap 22 with the implant lock 23 can be connected to the needle 5 and / or the connecting device 5B.

[0217] Then, preferably, the pusher 7 is inserted into the needle 5. Before or after the pusher 7 is inserted into the needle 5, the blocking device 38 is connected to the connecting device 5B and / or is placed above the needle 5 and / or the pusher 7 and / or between the pusher 7 (particularly the interlocking section 40A) and the connecting device 5B, in particular so that the pusher 7 and / or the needle 5 is received or arranged in the groove 39.

[0218] Afterwards, the other sections of the implant device 1 (particularly the housing 3, the plunger 4 and the actuator 8) are preferably connected to the assembly with the connecting device 5B, the pusher 7 and the blocking device 38. In particular, the connection is achieved by pushing the plunger 4 toward the pusher 7 to connect the plunger 4 to the pusher 7, so that the interlocking sections 40A, 40B are connected to each other (particularly by snapping or the like). In addition, when the pusher 7 and the plunger 4 are connected to each other, the housing 3 and the connecting device 5B are preferably connected to each other at the same time.

[0219] During assembly, the obstruction 38 preferably blocks or prevents the movement of the pusher 7 toward the implant 2 by receiving the pusher 7 in the groove 39. Specifically, the movement of the pusher 7 is prevented by the interlocking section 40A and / or the tapered section and / or the undercut 40C. Therefore, preferably, the obstruction 38 protects the implant 2 from being contacted, moved and / or damaged by the pusher 7 during assembly. This is particularly advantageous during the step of connecting the plunger 4 to the pusher 7.

[0220] In the following, particular reference will be made to Figures 13 to 16 A second embodiment of the implant device 1 is described.

[0221] Figures 13 to 16 A second embodiment of the implant device 1 according to the present invention is shown. Figures 1 to 6 The first embodiment shown in Figures 13 to 16 The main difference between the implant device 1 of the second embodiment shown in the figure is that the implant device 1 according to the second embodiment does not include an actuator 8. Apart from this, the implant device 1 according to the second embodiment preferably has the same features or at least most of the features as the implant device 1 according to the first embodiment, and vice versa. Therefore, if not explicitly indicated otherwise or it is obvious from the context, the features explained in connection with the first embodiment are also features of the second embodiment, and vice versa, even if this is not explicitly mentioned.

[0222] Fig.13 A perspective view of an implant device 1 according to the second invention is shown. Fig.14 A side view of an implant device 1 according to a second embodiment is shown. Fig.15 and Fig.16 Different cross sections of an implant device 1 according to a second embodiment are shown.

[0223] In the second embodiment, the plunger 4 is preferably movable by pushing against an axial end 4A of the plunger 4 , which is in particular arranged opposite the axial end of the plunger 4 facing or pointing towards the needle 5 and / or the connecting device 6 .

[0224] The axial end 4A preferably projects laterally from the plunger 4 and / or has a larger diameter than other sections of the plunger 4 and / or a cross section perpendicular to the axis A. Preferably, the axial end 4A comprises and / or forms an actuation section of the plunger 4A and / or is configured for actuating and / or moving the plunger 4.

[0225] Thus, in the second embodiment, the implant device 1 is actuatable or actuatable and / or movable or moved, preferably by pushing against the axial end 4A or the actuation section of the plunger 4 .

[0226] The implant device 1 preferably has at least one securing device 24, 25. Particularly preferably, the implant device 1 has at least or exactly two securing devices 24, 25. The securing devices 24, 25 are hereinafter referred to as "first securing device 24" and "second securing device 25".

[0227] The expression "first securing device 24" and "second securing device 25" does not imply the order or sequence of the securing devices 24, 25. Furthermore, the term "first securing device" does not necessarily imply the presence of a second securing device. Likewise, the term "second securing device" does not necessarily imply the presence of two securing devices or a first securing device. Thus, the implant device 1 may comprise only one of the first and second securing devices 24, 25.

[0228] Although described herein in conjunction with the second embodiment, the implant device 1 according to the first embodiment may further include the first fastening device 24 and / or the second fastening device 25 .

[0229] The first fastening means 24 is preferably configured to prevent or hinder the plunger 4 from moving away from the needle 5 and / or the connecting means 6 axially (ie, in the direction of Fig.15 and Fig.16 right side of the movement.

[0230] The first fastening device 24 is preferably designed as a clip or a clamp etc. Preferably, the first fastening device 24 is connected or connectable to the housing 3 and / or the plunger 4. Furthermore, the first fastening device 24 is preferably removable from the housing 3 and / or the implant device 1, in particular without destroying or damaging the first fastening device 24.

[0231] Preferably, the first fastening means 24 is made of a flexible and / or elastic material, in particular plastic.

[0232] The first fastening device 24 is particularly designed to be removable from the implant device 1, the housing 3 and / or the plunger 4 by pulling it radially away from the longitudinal axis A. In particular, the first fastening device 24 has such flexibility that when the first fastening device 24 is pulled radially away from the longitudinal axis A, the first fastening device 24, in particular the first and / or (one or more) second gripping sections 24A, 24B are deformed, and thus can be easily removed from the housing 3, the implant device 1 and / or the plunger 4.

[0233] The first fastening device 24 preferably at least partially surrounds the housing 3 and / or the plunger 4 or is configured for this purpose.

[0234] The first fastening device 24 preferably has a first gripping section 24A. The first fastening device 24 and / or the first gripping section 24A are preferably designed to grip and / or at least partially surround the housing 3 .

[0235] Furthermore, the first fastening device 24 preferably has a second gripping section 24B. The first fastening device 24 and / or the second gripping section 24B are preferably designed to grip and / or at least partially surround the plunger 4 .

[0236] The first and / or second gripping section 24A, 24B preferably has a C-shape.

[0237] The implant device 1 and / or the housing 3 preferably comprises a flange 28, which is particularly arranged at an axial end of the housing 3 opposite to the axial end 3A. The flange 28 preferably projects laterally from the housing 3 and / or is arranged transversely, particularly perpendicularly to the axis A.

[0238] The flange 28 preferably forms a stop for the first fastening means 24 , in particular the first gripping section 24A. In particular, the flange 28 is designed to hinder or prevent movement of the first fastening means 24 , in particular the first gripping section 24A, away from the needle 5 and / or the connecting device 6 .

[0239] The plunger 4 preferably comprises a stop means 29. The stop means 29 is particularly configured for preventing movement of the plunger 4 away from the needle 5 and / or the connecting means 6. In particular, the stop means 29 cooperates or is designed to cooperate with the first fastening means 24, in particular the second gripping section 24B.

[0240] The stopper 29 is preferably designed as a flexible arm. In particular, the stopper 29 or arm comprises a longitudinal section 29A (in particular extending along the axis A) and a transverse section 29B (in particular extending transversely, in particular perpendicular to the axis A and / or the longitudinal section 29A). In particular, the transverse section 29B protrudes laterally from the plunger 4.

[0241] The stop means 29 or the transverse section 29B is in particular configured to rest against the first gripping means 24 , in particular against the second gripping section 24B.

[0242] In particular, the first fastening means 24, the flange 28 and the stop means 29 cooperate to prevent the movement of the plunger 4 away from the needle 5 and / or the connecting device 6. In particular, the movement of the plunger 4 away from the needle 5 and / or the connecting device 6 can be prevented by the stop means 29, in particular its side section 29B, abutting against the first fastening means 24, in particular its second gripping section 24B, wherein the gripping means 24 is simultaneously held in place by the first gripping portion 24A placed against the flange 28.

[0243] In other words, when the fastening device 24 is arranged at the housing 3 and / or connected thereto, the plunger 4 cannot move away from the needle 5 and / or the connecting device 6 because, during such (attempted) movement, the side section 29B is placed against the second gripping section 24B, and the second gripping section 24B does not move because the first fastening device 24 is held in place by the first gripping section 24A placed against the flange 28.

[0244] The stop means 29 is preferably flexible, in particular such that a movement of the plunger 4 towards the needle 5 and / or the connecting means 6 is allowed and / or is not blocked or hindered by the stop means 29 .

[0245] In particular, when the plunger 4 moves from the initial position toward the needle 5 and / or the connecting device 6, the stop device 29, in particular the side section 29B, will contact the housing 3. When the plunger 4 is subsequently moved further toward the needle 5 and / or the connecting device 6, the stop device 29 preferably flexes or bends or moves inwardly so that the contact between the side section 29B and the housing 3 does not prevent or hinder further movement of the plunger 4.

[0246] In particular, the housing 3 comprises a ramp 31. The ramp 31 and / or the stop 29, in particular the transverse section 29B, are configured such that contact of the stop 29 or the transverse section 29B results in an inward movement of the stop 29 and / or a sliding movement of the stop 29 and / or the transverse section 29B along the ramp 31.

[0247] The stop means 29 , in particular the longitudinal section 29A, is preferably formed and / or allows movement by a cutout 32 in the plunger 4 , forming or defining the stop means 29 or the longitudinal section 29A.

[0248] The second fastening means 25 is preferably configured to prevent or hinder the plunger 4 from moving axially (ie, toward) the needle 5 and / or the connecting means. Fig.15 and Fig.16 to the left in the image.

[0249] The second fastening means 25 is preferably arranged or arrangeable between the axial end 4A of the plunger 4 and the housing 3 (in particular the flange 28 ) and / or the first fastening means 24 (in particular the second gripping section 24B).

[0250] The second fastening device 25 is preferably designed as a clip or a clamp etc. Preferably, the second fastening device 25 is connected or connectable to the plunger 4. Furthermore, the second fastening device 25 is preferably removable from the plunger 4 and / or the implant device 1, in particular without destroying or damaging the second fastening device 25.

[0251] Preferably, the second fastening means 25 is made of a flexible and / or elastic material, in particular plastic.

[0252] The second fastening means 25 preferably at least partially surrounds the plunger 4 or is configured for this purpose.

[0253] The second fastening device 25 preferably has a gripping section 25A. The second fastening device 25 and / or the gripping section 25A are preferably designed to grip and / or at least partially surround the plunger 4.

[0254] The gripping section 25A preferably has a C-shape.

[0255] The second fastening device 25 preferably has a pick-up section 25B. The pick-up section 25B is preferably configured for gripping or picking up by a user, in particular in order to remove the second fastening device 25 from the implant device 1 or the plunger 4, in particular by pulling the second fastening device 25 radially away from the implant device 1 or the plunger 4.

[0256] The pick-up section 25B is preferably designed as a sheet or plate and is in particular flat. Preferably, the pick-up section 25B is thickened at the end opposite to the gripping section 25A.

[0257] In the second embodiment, the aforementioned friction between the plunger 4 and the housing 3 or the inner wall 3D is preferably generated by one or more, in particular two, O-rings 30. The O-ring 30 preferably surrounds the plunger 4 and in particular contacts the housing 3 or the inner wall 3D.

[0258] The O-ring 30 may also be present in the first embodiment, although not shown in the figure. In addition, as an addition or replacement of the O-ring 30, the second embodiment may also have the same means for generating friction between the plunger 4 and the housing 3 as described in connection with the first embodiment.

[0259] The O-ring 30 preferably has one or more grooves (not shown). The grooves preferably allow air to pass between the O-ring 30 and the housing 3 or wall 3D and / or form an air passage 27 or part thereof.
