Description
TECHNICAL FIELD
[0001] The invention relates to a supply device (Bereitstellungsvorrichtung) for storing and transporting catheters, in particular balloon catheters for percutaneous transluminal coronary angioplasty. BACKGROUND
[0002] Balloon catheters for percutaneous transluminal coronary angioplasty, also referred to as PTCA catheters, are used for the treatment of highly stenosed coronary arteries. For the treatment thereof, the balloon catheter is introduced into the coronary artery via a guide wire and is inflated.
[0003] The PTCA catheters currently available on the market are transported and stored in so-called "dispensers". Here, the dispenser is a long plastic hose which is longer than the catheter itself. The plastic hose is wound into a coil with the contained catheter and is secured against unrolling with a clip. The inserted catheter can be safely transported and stored in this packaging.
[0004] The problem of the described dispensers is on the one hand the cumbersome handling, in particular the taking out of the catheter, and on the other hand the environmental compatibility. The plastic hose which is used only as packaging accounts for the largest share of the plastic requirement of the entire product, namely approximately 95%.
[0005] From JP 2016-064089 A a holding device, in particular for medical equipment, is known. JP 2012-176101 A relates to a packaging for medical devices, in particular catheters. In WO 2019 / 171672 A1 a storage device for articles having a long extension is described. DE 43 33 073 A1 discloses a packaging for hose-shaped goods. From US 4,332,322 a folding packaging for holding a plastic tube reel with a clamp and a corresponding profile is known. US 5,131,537 relates to a packaging for medical catheters. In US 2005 / 0194276 A1 a packaging for elongated medical devices and a method for making and using the same is described. SUMMARY
[0006] It was therefore the task of the present invention to improve the supply device of the type described at the outset.
[0007] In a supply device of the type described at the outset, the task is thereby solved according to the application in that the supply device comprises a carrier and a holding device arranged or constructed at the carrier for holding a ring-shaped coiled catheter in a storage position, the holding device comprising at least three holding elements which engage with the catheter in the storage position and which are arranged or constructed at the carrier spatially separate from one another, the at least three holding elements being positioned along a holding circle which defines a holding circle center point, at least one of the at least three holding elements, in particular all of the holding elements, being constructed in the form of a holding tab, a free holding tab end of the holding tab being oriented pointing in the direction of a carrier center of the carrier, and the holding device comprising at least two stop elements for preventing a movement of the catheter in the storage position in the direction of the holding circle center point.
[0008] In particular, the proposed improved supply device achieves the holding of the coiled catheter at the carrier in a simple manner. For this purpose, at least three holding elements are used. In particular, only three holding elements can be provided. These holding elements serve to support the coiled catheter, for example, at three points or at three short abutment sections. Such an arrangement achieves, in particular, the handling of the catheter in a simple manner. In particular, both end portions of the catheter can thus be held freely accessible at the supply device or at the carrier thereof. In comparison with the known packaging device described at the outset, this significantly improves the handling of the supply device. In particular, depending on the specific arrangement of the holding elements, the catheter can be removed from the supply device as a whole, i.e. coiled. This is not possible in catheters stored in plastic hoses. In such hose storage, the catheter must first be pulled completely out of the hose in order to make both end portions freely accessible at the same time. The proposed improved supply device furthermore has, in particular, a significantly better environmental balance. The carrier can be configured very flat, so that on the one hand material for its manufacture is saved compared with plastic hoses and on the other hand the supply device with the catheter held at it, which can likewise be fitted maximally flat at the carrier, can even be configured flatter than the known hose packaging described. In this way, the space requirement of the product is significantly reduced. In this way, the manufacturing costs, the transport costs and the storage costs can be significantly reduced. The holding of the circularly coiled catheter at the carrier in a simple manner is achieved by the positioning of the at least three holding elements along a holding circle which defines a holding circle center point. In particular, the holding circle center point can be positioned in the region of a carrier center of the carrier by the corresponding arrangement of the at least three holding elements. It is advantageous if at least one, in particular all, of the at least three holding elements is configured in the form of a holding tab and the free holding tab end is oriented pointing in the direction of the carrier center of the carrier. The carrier center can in particular be the holding circle center point. The holding tab can be configured at the carrier in a simple manner, in particular by bonding or alternatively also by integral configuration from the carrier itself. This will be explained in more detail below. Furthermore, it is provided that the holding device comprises at least two stop elements for preventing a movement of the catheter in the direction of the holding circle center point in the storage position. In particular, in addition to the holding elements, the stop elements can further improve the storage of the catheter at the supply device. The proposed supply device is in particular advantageous for PTCA catheters. This catheter can comprise a guide wire which forms a kind of return device in the form of a spring-elastic element in order to stabilize the catheter in an elongated form. This is in particular advantageous when the catheter is introduced into the blood vessels of a patient. However, the guide wire can also cause an undesired springing out of the coiled position into its elongated basic position if the catheter is not fixed in an appropriate manner.To this end, the proposed supply device is in particular provided to remedy this, since the supply device can safely and definedly position the catheter in the storage position with at least three holding elements which engage the catheter in the storage position, at least one of which prevents movement of the catheter in the direction of the center point of the holding circle and at least one of which prevents movement of the catheter away from the center point of the holding circle, and can hold it at the carrier in the wound storage position. For so-called OTW catheters, which are flexible, such support is not necessary. OTW catheters do not comprise a stabilizing guide wire, so that such catheters cannot be easily sprung into the elongated basic position either as is the case with PTC catheters.
[0009] It is expedient for the supply device to be configured to disengage the wound catheter from the at least three holding elements without bringing the catheter into the stretched form. As already explained, the catheter can thus be removed as a whole, i.e. in the wound position, from the supply device. Both end portions of the catheter are then freely accessible.
[0010] Advantageously, two of the at least three holding elements are positioned point-symmetrically with respect to the center point of the holding circle. If a third holding element is positioned between the two holding elements along the holding circle, a free area extending almost 180° is created between the holding elements which are positioned opposite one another with respect to the center of the holding circle. This is in particular achieved to safely hold the catheter at the supply device, in addition to which the catheter is also removed from the supply device in a wound manner. For this, only a small deformation of the wound catheter is necessary.
[0011] It is expedient for the at least three holding elements to define a holding area which corresponds to at least a 180° holding circumferential angle of the holding circle. In this way, the wound catheter can be safely held at the supply device.
[0012] It is advantageous for the holding circumferential angle to lie in the range between 180° and 240°. In particular, the holding circumferential angle can lie in the range from approximately 185° to approximately 200°. For reliable storage, it is advantageous for the holding circumferential angle to be greater than 180°.
[0013] According to a further preferred embodiment, it can be provided that the carrier has an outer carrier edge which surrounds the storage area, and that the catheter is arranged within the storage area in the storage position. This design is in particular achieved to hold the catheter in a protected manner at the supply device. Even when the user impacts the supply device with the catheter stored there at the carrier edge with an object, the catheter is still well protected from damage.
[0014] Advantageously, the holding tab is configured by a holding cut line configured at the carrier with two free end portions, the holding tab defining a holding tab base line connecting the two free end portions of the holding cut line, and a free holding tab length of the holding tab being defined by the distance of the free holding tab end portion from the holding tab base line. Thus, for configuring the holding tab, it is only necessary to configure the cut portion at the carrier such that the holding cut line has two free end portions spaced apart from one another. The holding tab can then be pivoted out of the carrier plane, in particular the carrier plane defined by the carrier, along the holding tab base line. It is also conceivable to bend or fold the holding tab along the holding tab base line. With such a holding tab, the catheter can be safely held at the carrier. For example, the bent-out holding tab forms a wedge-shaped recess in which the catheter can be held, optionally even in a clamped manner.
[0015] For simple handling, it is expedient for the holding cut line to be convexly curved in the direction towards the centre of the carrier. In this way, a holding tab can be configured with rounded holding tab end portions which keep the risk of damaging the catheter to a minimum.
[0016] Preferably, the holding cut line is at least section-wise curved, in particular configured in the shape of a circular arc section. Such a holding cut line can be configured in a simple manner by means of a punching cut.
[0017] For configuring a triangular or quadrangular holding tab, it is expedient for the holding cut line to comprise at least two, in particular three holding line sections. These holding line sections can be inclined to one another, for example.
[0018] It is particularly expedient for at least two holding line sections to be at least section-wise straight or substantially straight. In this way, a triangular or quadrangular holding tab can be realized in a simple manner.
[0019] Preferably, the holding tab base lines of at least two holding tabs run parallel or substantially parallel to one another. Such an arrangement results, for example, when the two holding tabs are positioned point-symmetrically about a holding circle centre point. In this way, the two holding tabs act at mutually opposite sides of the wound catheter in order to hold the catheter at the supply device.
[0020] Advantageously, the holding tab base lines of at least two holding tabs run transversely, in particular perpendicularly, to one another. Arranging the two holding tabs in this way ensures, in particular, that the wound catheter cannot be moved in the direction of the two holding tabs in order to remove it from the supply device. In particular, a reliable fixing of the catheter at the supply device is achieved in this way.
[0021] In order to be able to construct the carrier with a minimum size, it is expedient for the holding tab base line of the at least one holding tab to be at a distance from the carrier edge which is less than the free holding tab length thereof. In this way, the material input for constructing the supply device can be minimised.
[0022] It is advantageous for the at least one holding tab to be positioned in the vicinity of the carrier edge, and for the holding tab base line of the holding tab to run parallel or substantially parallel to the carrier edge. This design also achieves a minimisation of the size of the carrier, in particular.
[0023] It is expedient for at least one, in particular all, of the at least two stop elements to be constructed in the form of a stop tab, and for the free stop tab end of the stop tab to be oriented pointing away from the carrier centre in the radial direction. In this way, in particular, a wedge-shaped, radially pointing away from the carrier centre accommodation for accommodating a section of the coiled catheter can be constructed by means of the stop tab. In particular, the stop tab prevents movement of the coiled carrier towards the carrier centre or the centre point of the holding circle.
[0024] It is advantageous for the stop tab to be constructed by means of a stop cut line constructed at the carrier, having two free ends, for the stop tab to define a stop tab base line connecting the two free ends of the stop cut line, and for the free stop tab length of the stop tab to be defined by the distance of the free stop tab end from the stop tab base line. As explained, the stop tab can thus be constructed integrally with the carrier. For this, it is only necessary to construct the stop cut line, i.e. to construct the respective cut at the carrier. The stop tab can then be brought into the desired position by deforming it relative to the carrier, in order to form, in particular, a wedge-shaped accommodation for the coiled catheter.
[0025] It is expedient for the stop cut line to be concavely curved at least in sections towards the direction of the carrier centre, in particular in the shape of circular arc sections. In this way, a wedge-shaped accommodation which opens in the radial direction can be implemented by means of the stop tab in a simple manner.
[0026] It is advantageous for at least one, in particular all, of the at least two stop elements to be positioned between two holding elements having a maximum angular distance from one another along the holding circle. In this way, the stop elements do not significantly hinder the removal of the coiled catheter from the supply device. Preferably, the stop elements are positioned in the vicinity of the two holding elements such that the coiled catheter is optimally secured both towards and away from the centre point of the holding circle in the region in which the stop tabs and the holding tabs are arranged adjacent to one another.
[0027] According to a further preferred embodiment provision can be made for the supply device to comprise an adapter holding device for arranging or configuring a coupling adapter at the first end of the catheter. This design in particular enables the catheter to be left at the supply device in order to prepare it for a procedure. It is not mandatory to remove it. By virtue of the coupling adapter which is also held at the supply device, i.e. at the adapter holding device, the catheter can be easily flushed. Here, the catheter in particular can be retained in a wound-up manner at the supply device.
[0028] When the adapter holding device comprises at least two adapter holding elements, the coupling adapter can be held at the supply device in a secure manner.
[0029] Advantageously, the two co-acting adapter holding elements are configured in the form of adapter holding tabs, and the free adapter tab ends of the two adapter holding elements are oriented pointing towards one another. This in particular enables the coupling adapter to be held with its longitudinal axis oriented in a direction transverse to the adapter tab ends pointing towards one another, by means of the adapter holding tabs.
[0030] Suitably, the adapter tab ends pointing towards one another are spaced apart from one another in order to configure an adapter holding web at the carrier. In this way, the coupling adapter can be stably held at the supply device, in particular supported by means of the adapter holding web.
[0031] Advantageously, the adapter holding device defines an adapter holding longitudinal axis, and the adapter holding web extends parallel or substantially parallel to the adapter holding longitudinal axis. In this way, the coupling adapter can in particular be supportedly held at the supply device by means of the adapter holding web.
[0032] When the adapter holding device is configured symmetrically about the adapter holding longitudinal axis, the supply device can be configured in a simple manner.
[0033] Advantageously, the holding tab base line of the holding tab is oriented parallel or substantially parallel to the adapter holding longitudinal axis. In this way, the free end of the catheter, i.e. the first end with the coupling adapter, can in particular be guided without kinks from the holding tab to the adapter holding device when wound onto the supply device.
[0034] Suitably, an adapter recess is configured adjacent to the adapter holding device at the carrier, starting from the carrier edge in the extension of the adapter holding longitudinal axis. Such an adapter recess in particular enables the coupling adapter to be positioned such that a coupling element of the coupling adapter, which can for example be configured in the form of a luer lock coupling, can protrude from the supply device. This in particular enables the catheter to be coupled, for example to a flushing device for flushing the catheter, without the catheter, in particular the coupling adapter, having to be removed from the supply device.
[0035] According to a further preferred embodiment provision can be made for the supply device to comprise a balloon holding device for arranging or configuring an inflatable balloon in the region of the second end portion of the catheter. Such a balloon holding device in particular enables the catheter to be positioned and stored safely in the region of the inflatable balloon.
[0036] It is expedient for the balloon holding device to define a balloon holding longitudinal axis and for the balloon holding device to be configured asymmetrically with respect to the balloon holding longitudinal axis. In this way, the balloon or the second end portion region of the catheter can be reliably held at the supply device.
[0037] Preferably, the balloon holding device comprises at least two balloon holding elements. For example, the balloon holding device can comprise two balloon holding elements which can be configured in the form of tabs.
[0038] It is advantageous for the two co-acting balloon holding elements to be configured in the form of balloon holding tabs and for the free balloon holding tab end portions of the balloon holding tabs to point in the same direction in the undeformed initial position of the supply device. This design enables one of the two balloon holding tabs, for example, to be deformed or folded such that it supports the other balloon holding tab and can hold it in a position which is set back from the carrier. In this way, the catheter can be positioned optimally supported in the region of the balloon at the supply device.
[0039] It is expedient for each of the balloon holding tabs to be configured by a balloon holding cut line configured at the carrier with two free end portions, for the balloon holding tab to define a balloon holding tab base line which connects the two free end portions of the balloon holding cut line, and for the free balloon holding tab length to be defined by the distance of the free balloon holding tab end portion from the balloon holding tab base line. As already explained in the holding tabs, the balloon holding tabs for holding the catheter in the region of the inflatable balloon can thus be configured in a simple manner.
[0040] In order to keep the risk of damage to the catheter as low as possible, it is advantageous for the balloon holding cut line to be configured in a curved manner, in particular in the shape of a circular arc segment.
[0041] It is advantageous for the balloon holding tab base lines of the two co-acting balloon holding tabs to run parallel or substantially parallel to one another and parallel to the balloon holding longitudinal axis. In this way, the catheter section with the balloon can be held linearly by the co-acting balloon holding tabs.
[0042] It is expedient for the balloon holding cut lines of the two co-acting balloon holding tabs to be of different lengths and / or to have different radii of curvature. In this way, the balloon holding tabs can be configured differently large in a simple manner.
[0043] Advantageously, the two co-acting balloon holding tabs keep the balloon holding tab lengths of the balloon holding tabs the same or substantially the same. This can be achieved, in particular, when the balloon holding cut lines are not of the same length or have different radii of curvature. In this way, balloon holding tabs of different face sizes can be configured in a simple manner.
[0044] Suitably, the holding tab base line of the holding tab is oriented parallel or substantially parallel to the balloon holding longitudinal axis. This design achieves, in particular, the unbent deployment of the second free end of the catheter in the tangential direction from the holding circle and the holding with the balloon holding device.
[0045] According to a further preferred embodiment, it can be provided that a tip recess is arranged or configured at the carrier and that the second end of the catheter is positioned in the region of the tip recess in the storage position. Such a tip recess enables the user to grasp the free tip, i.e. the second end, of the catheter in a simple manner in order to start the stepwise unwinding of the catheter from the supply device from this end.
[0046] Advantageously, the tip recess is positioned adjacent to the balloon holding device in the direction of the balloon holding tab. This arrangement has the advantage, in particular, that the second end does not need to be supported itself, since it is reliably held adjacent to the balloon region at the supply device.
[0047] Suitably, the tip recess is configured in the form of a perforation of the carrier. Such a perforation can be configured in a simple manner, for example by punching. In particular, the perforation can be configured circularly.
[0048] For optimal operation of the supply device, it is advantageous if the tip recess is dimensioned in such a way that it enables the second end of the catheter held at the supply device to be grasped with two fingers. For example, this free end can be easily grasped and operated with the thumb and index finger of one hand.
[0049] According to a further preferred embodiment, it can be provided that a removal recess is arranged or configured at the carrier and that, in the storage position, at least two, in particular three, catheter sections of the catheter held wound at the carrier are positioned in the region of the removal recess. This design enables the user to safely grasp the catheter, i.e. two or more sections of it at a time, so that the risk of the catheter completely unwinding, i.e. transitioning into the stretched state, when it is removed from the carrier can be minimized. In this way, the user is facilitated in removing the catheter as a whole from the supply device.
[0050] Suitably, the removal recess is configured in the form of a perforation at the carrier. Such a perforation can be configured in a simple manner by punching. The perforation enables the wound catheter to be freely accessed.
[0051] Preferably, the removal recess is configured in the form of an annular segment. In this way, the removal recess can in particular be configured to follow the shape of the coiled catheter. This in particular improves handling of the supply device and the catheter.
[0052] Suitably, the center line of the annular segment has a curvature which substantially corresponds to the curvature of the coiled catheter held at the supply device in the storage position. In this way, the catheter can be well grasped by the user over the entire length of the removal recess in the circumferential direction about the center point of the holding circle and removed from the supply device.
[0053] Preferably, the annular segment extends over an angular range of approximately 30° to approximately 60°, in particular over an angular range of approximately 40° to approximately 50°.
[0054] Advantageously, the removal recess has a width in the radial direction about the center point of the holding circle which enables the catheter held at the supply device to be grasped with two fingers. In this way, the user can in particular reliably and without damaging the catheter remove the catheter from the supply device.
[0055] Preferably, the removal recess is positioned between two holding elements on the holding circle which have a maximum angular distance from one another. At the described position, the catheter can be gripped by the user and pulled off the carrier by the holding tabs or the like with minimal effort and without significant resistance, i.e. in particular in coiled form.
[0056] According to a further preferred embodiment, it can be provided that the supply device comprises a guide wire holding device for holding a free end of a guide wire which protrudes from an opening of the guide wire channel of the catheter pointing in the direction of the first end of the catheter. This design in particular enables the guide wire, which is usually used for transport purposes, to be held at the supply device in a targeted manner. In particular, the guide wire can in this way also be grasped by the user in a targeted manner. Preferably, the guide wire holding device is arranged or configured at the carrier in such a way that it is neither positioned on the holding circle nor on the adapter holding longitudinal axis. In this way, one free end of the guide wire can be held easily accessible separately from the coiled catheter and also independently of the first end of the catheter. Suitably, the guide wire holding device is arranged or configured in the region between the holding circle and the adapter holding device.
[0057] Suitably, the guide wire holding device comprises at least one guide wire holding element. With this guide wire holding element, the guide wire can be reliably held at the supply device in the desired orientation.
[0058] Advantageously, the at least one guide filament holding element is configured in the form of a guide filament holding tab, and a free guide filament holding tab end of the guide filament holding tab is oriented pointing in the direction of the carrier center. This design in particular achieves a reliable holding of the free guide filament end at the supply device. In particular, this orientation of the guide filament holding tab can prevent the free end from being pushed out, in particular beyond a carrier edge of the carrier.
[0059] Advantageously, the guide filament holding tab is configured by a guide filament holding cutout line configured at the carrier having two free ends, the guide filament holding tab defines a guide filament holding tab base line connecting the two free ends of the guide filament holding cutout line, and a free guide filament holding tab length of the guide filament holding tab is defined by the distance of the free guide filament holding tab end from the guide filament holding tab base line. Such a guide filament holding tab can be configured integrally with the carrier in a simple manner, as already explained above in connection with the holding tab.
[0060] When the supply device is configured from a flat material, the supply device can be implemented simply and cost- effectively. In this way, the dimensions, in particular the volume occupied by the supply device, can also be kept to a minimum.
[0061] Preferably, the flat material from which the blank forming the supply device is made is hardboard or cardboard. The supply device can be manufactured cost-effectively and simply from this flat material, for example by punching. Suitably, the flat material is coated with plastic. In this way, the supply device can be configured, in particular, to be waterproof, also when the flat material is not waterproof, for example hardboard or cardboard.
[0062] Suitably, the flat material from which the blank forming the supply device is made consists of plastic. This in particular achieves that the carrier is configured integrally from plastic. Such a supply device can be configured, in particular, to be waterproof. Furthermore, cutting edges at a flat material consisting of hardboard or cardboard can cause problems, because such paperboard always contains fibers, the ends of which can project freely. This can lead to an undesired loosening of fibers from the carrier, in particular in a sterile environment. As a result, the cutting edges of such a conductor consisting of hardboard or cardboard can need to be treated by additional processing steps, for example by coating or laminating the cutting edges and, if necessary, other areas of the carrier, or otherwise covering the partly exposed fibers or bonding them to the carrier. This problem does not occur with a flat material consisting of plastic. The flat material can be configured, in particular, in the form of a film or in the form of a plate.
[0063] In order to avoid as far as possible that a carrier configured from hardboard or cardboard is damaged by liquids, advantageously the carrier is provided with a liquid-proof coating. For example, the coating can be configured to be waterproof.
[0064] Preferably, the liquid-proof coating is constructed from plastic. In particular, the coating can be formed by a plastic film, which is laminated to the carrier.
[0065] Preferably, the plastic used for coating or constructing the flat material is or contains polypropylene (PP), high-density polyethylene (HDPE), polylactic acid (PLA, in particular PLLA), polyamide (PA), polyethylene (PE), low-density polyethylene (LDPE) and / or polyethylene terephthalate (PET). In this way, the supply device can be simply and cost- effectively constructed.
[0066] When the supply device is constructed in one piece, in particular monolithically, the manufacture of the supply device can be further simplified.
[0067] In order to keep the spatial requirements of the supply device as small as possible, it is advantageous if the carrier has a carrier thickness in the range of approximately 0.05 mm to approximately 1 mm, in particular in the range of approximately 0.2 mm to approximately 0.4 mm.
[0068] According to a further preferred embodiment, it can be provided that the supply device has a front side and a rear side, and the holding device is constructed for holding the catheter on the front side. In particular, all elements of the holding device as well as all other elements described above can be arranged or constructed at the supply device in such a way that the catheter can be reliably fixed on one side of the carrier, i.e. on the front side, in the storage position.
[0069] It is expedient if the supply device comprises at least one data storage element for storing characteristic data of the catheter, in particular length, diameter, inflation pressure and balloon diameter. The data storage element can in particular be an electronic data storage element. The data storage element can for example be read wirelessly with a corresponding reading device. In this way, in particular the documentation of the medical procedure can be simplified.
[0070] It is advantageous if the at least one data storage element is arranged on the front side or the rear side and is configured for visual reading. For example, the data storage element can be configured in the form of a bar code or a QR code. Alternatively, the characteristic data of the catheter can also be printed in the form of readable text in a spatially limited data area on the front side and / or the rear side, so that the user can directly read all data characteristic of the catheter itself without the aid of technical aids, such as a reading device.
[0071] According to a further preferred embodiment it can be provided that the supply device comprises a catheter, in particular a PTCA catheter. This catheter can in particular comprise a guide wire which forms a kind of a repositioning device in order to stabilize the catheter in an elongated form. This is advantageous in particular when the catheter is introduced into the blood vessels of a patient. The proposed supply device is in particular advantageous for such catheters since it positions the catheter safely and defined with at least three holding elements which engage the catheter in the storage position (of which at least one prevents a movement of the catheter in the direction towards the center point of the holding circle and at least one prevents a movement of the catheter away from the center point of the holding circle) and can hold it at the carrier in a wound storage position. For so-called OTW catheters (which are flexible) no support as proposed is necessary. OTW catheters do not comprise a guide wire so that such catheters cannot be easily sprung into an elongated basic position as in the case of PTC catheters either.
[0072] It is expedient that the catheter has a first end at which a coupling adapter is arranged or configured and a second end in the region of which an inflatable balloon is arranged or configured. With such a catheter it is in particular possible to treat a coronary stenosis as already explained above, i.e. by dilating the coronary vessel by means of the balloon.
[0073] In order to protect the conductor, in particular the balloon, it is advantageous that at the second end a removable protection sheath is arranged which wraps around the balloon.
[0074] In order to be able to inflate the balloon with gas in a simple manner, it is advantageous that the catheter comprises a fluid channel which fluidically connects the coupling adapter with the balloon.
[0075] It is furthermore expedient that the catheter comprises a guide wire channel for a guide wire and that the guide wire channel extends in a proximal direction from the second end up to an introduction opening which is arranged or configured at the catheter between the first end and the second end. Preferably, the introduction opening is arranged or configured closer to the second end than the first end at which the coupling adapter is arranged. The guide wire channel in particular enables the catheter to be guided to the coronary vessel in the case of a guide wire being used.
[0076] It is advantageous that the catheter comprises a guide wire which is arranged in the guide wire channel and which is longer than the guide wire channel. In this way, the guide wire, which is positioned in the guide wire channel for example for transport purposes, protrudes from the guide wire channel at one end so that it can be easily grasped and pulled out by a user.
[0077] It is expedient that the guide wire is configured in the form of a transport guide wire. This guide wire is used only for transport purposes, in particular in order to hold the catheter as shape-stable as possible at the supply device.
[0078] Advantageously, the catheter is held in the storage position at the supply device such that the first end portion and / or the second end portion is oriented transversely, in particular perpendicularly, to the carrier edge. In particular, the first end portion and the second end portion can be held at the supply device pointing towards the same side of the carrier. This in particular significantly improves the handling of the supply device. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION
[0080] In Figure 1A first embodiment of a supply device for storing and transporting catheters 12 is shown schematically in its entirety by the reference numeral 10. The catheters 12 are configured in the form of balloon catheters 14 for percutaneous transluminal coronary angioplasty.
[0081] The catheters 12 have a first end portion 16 and a second end portion 18. At the first end portion 16 a coupling adapter 20 with a so-called luer lock coupling 22 is arranged or configured. In the region of the second end portion 18 an inflatable balloon 24 is arranged or configured. A protective sheath 26 is pushed on from the second end portion 18, which protective sheath surrounds the balloon 24 in a protective manner.
[0082] The catheters 12 comprise a fluid channel, not shown in the drawing, which fluidically connects the coupling adapter 20 with the balloon 24.
[0083] Furthermore, a guide wire channel for a guide wire 28 is configured at the catheter 12. The guide wire channel, not shown in the drawing, extends in the proximal direction from the second end portion 18 up to an introduction opening 30, which is arranged or configured at the catheter 12 between the first end portion 16 and the second end portion 18. The introduction opening 30 is at a smaller distance from the second end portion than from the first end portion 16.
[0084] The guide wire 28 is positioned in the guide wire channel of the catheter 12. The guide wire is longer than the guide wire channel, so that a proximal end portion 32 pointing in the direction of the coupling adapter 20 protrudes from the introduction opening 30. The guide wire 28 is configured in the form of a transport guide wire, which is removed before the medical procedure is carried out.
[0085] The supply device 10 comprises a carrier 34, at which a holding device 36 is arranged or configured for holding the ring-wound catheter 12 in a storage position. The holding device 36 comprises at least three, in the embodiment shown in the drawing exactly three, holding elements 38a, 38b and 38c, which in the storage position engage with the catheter 12.
[0086] As is well visible in the drawing, the three holding elements 38a, 38b and 38c are arranged or configured at the carrier 34 spatially separated from one another. However, these holding devices jointly act for holding the catheter 12 at the carrier 34.
[0087] The supply device 10, i.e. the carrier 34, is configured from a flat material which forms a carrier blank. In particular, cardboard and carton are suitable as flat material.
[0088] In an alternative embodiment, the flat material for configuring the carrier 34 is configured from plastic.
[0089] Optionally, the carrier 34 is provided with a liquid-tight coating 40, namely both on the front side 42 and on the rear side 44. The coating 40 is constructed from plastic. In particular, the coating can be realized in the form of a plastic film.
[0090] The flat material or the plastic coating the flat material is or comprises polypropylene (PP), high-density polyethylene (HDPE), polylactic acid (PLA, in particular PLLA), polyamide (PA), polyethylene (PE), low-density polyethylene (LDPE) and / or polyethylene terephthalate (PET).
[0091] The supply device 10 is constructed in one piece, namely integrally.
[0092] The carrier 34 has a carrier thickness 46 in the range of about 0.5 mm to about 1 mm. In particular, the carrier thickness 46 can have a value in the range of about 0.2 mm to about 0.4 mm.
[0093] The holding apparatus 36 is configured to hold the catheter 12 on the front side 42 of the carrier 34, as will be explained in detail below.
[0094] The three holding elements 38a, 38b and 38c are positioned along a holding circle 48, which is schematically drawn in dashed lines in Fig. Figure 7 The holding circle 48 defines a holding circle center point 50.
[0095] Two of the three holding elements 38a, 38b and 38c, namely the holding elements 38a and 38c, are positioned at the carrier 34 point-symmetrically with respect to the holding circle center point 50.
[0096] The three holding elements 38a, 38b and 38c define a holding region 52, which extends around the holding circle center point 50. The holding region 52 of the holding circle 48 defines a holding circle circumferential angle 54 of at least 180°. Preferably, the holding circle circumferential angle 54 has a value in the range between 180° and 240°. In the embodiment shown in the figures, the holding circle circumferential angle 54 is about 200°.
[0097] The carrier 34 has a circumferential outer carrier edge 56. The entire face of the front side 42 that is surrounded by the carrier edge 56 surrounds a storage region 58. The catheter 12 is arranged within the storage region 58 in the storage position, with the exception of the exceptional case that will be explained later.
[0098] The three holding elements 38a, 38b and 38c are constructed in the form of holding tabs 60. A free holding tab end 62 of the holding tab 60 is oriented pointing in the direction of a carrier center 64 of the carrier 34. In the embodiment shown in the figures, the holding circle center point 50 forms the carrier center 64.
[0099] The holding tab 60 is configured by a holding cut 66 configured at the carrier 35. The holding cut has two free end portions 68. A holding tab base line 70 of the holding tab 60 connects the two free end portions 68.
[0100] A free holding tab length 72 of the holding tab 60 is defined by the distance of the free holding tab end portion 62 from the holding tab base line 70. The holding cut 66 is convexly curved in the direction towards the carrier center 64. The holding cut has the shape of a circular arc segment.
[0101] The holding tab base lines 70 of the two holding tabs 60 forming the holding elements 38a and 38c run parallel to each other.
[0102] The holding tab base lines 70 of the holding tabs 60 forming the holding elements 38a and 38b run transversely, i.e. perpendicularly, to each other. The holding tab base lines 70 of the holding tabs 60 forming the holding elements 38b and 38c also run transversely, i.e. perpendicularly, to each other.
[0103] The holding tab base line 70 of the holding tab 60 forming the holding element 38b is at a distance 74 from the carrier edge 56 which is smaller than the free holding tab length 72 of the holding tab.
[0104] The three holding tabs 60 forming the holding elements 38a, 38b and 38c are each positioned in the vicinity of the carrier edge 56. The respective holding tab base line 70 runs parallel or substantially parallel to the carrier edge 56.
[0105] The carrier 34 has a substantially rectangular shape. Two adjacent corner portions 76 and 78 are rounded with a small radius, and another corner portion 80 adjacent to the corner portion 78 is rounded with a large radius. In the region of a fourth corner portion 82 defined between the corner portions 76 and 80, an adapter recess 84 is configured which shortens two straight carrier edge sections 86 and 88 of the carrier edge 56 (which define the corner portion 82).
[0106] Furthermore, the holding device 36 comprises two stop elements 90a and 90b. These stop elements are configured for preventing a movement of the catheter 12 in the storage position in the direction towards the holding circle center point 50.
[0107] The stop elements 90a and 90b are configured in the form of stop tabs 92. A free stop tab end portion 94 of the stop tab 92 is oriented in the radial direction away from the carrier center 64.
[0108] The stop tab 62 is configured by a stop cut line 96 at the carrier 34. The stop cut line 96 has two free end portions 98. The two free end portions are connected by a stop tab base line 100. A free stop tab length 102 of the stop tab 92 is defined by the distance of the stop tab end portions 94 from the stop tab base line 100. The stop cut line 96 is concavely curved in the direction towards the carrier center 64, i.e. curved in the shape of a circular arc segment.
[0109] The two stop elements 90a and 90b are positioned along the holding circle 48, i.e. between the two holding elements 38a and 38c having the greatest angular distance from each other. The angular distance between the holding elements 38a and 38b is about as great as the angular distance between the holding elements 38b and 38c, and is about 80° each. In contrast, the angular distance between the holding elements 38a and 38c is about 170°.
[0110] Furthermore, the supply device 10 comprises an adapter holding device 104 for holding the coupling adapter 20 arranged at the first end portion 16 of the conduit 12. The adapter holding device 104 comprises two adapter holding elements 106a and 106b.
[0111] The two co-acting adapter holding elements 106a and 106b are configured in the form of an adapter holding tab 108. The free adapter tab end portions 110 of the two adapter holding elements 106a and 106b are oriented pointing towards each other.
[0112] The adapter tab end portions 110 pointing towards each other are spaced apart from each other and thus form an adapter holding web 112 at the carrier 34.
[0113] The adapter holding device 104 defines an adapter holding longitudinal axis 114. The adapter holding web 112 extends parallel to the adapter holding longitudinal axis 114.
[0114] The adapter holding device 104 is configured symmetrically with respect to the adapter holding longitudinal axis 114. The adapter holding tab 108 is defined by an adapter cut line 116 comprising three straight line segments, thereby configuring a substantially quadrangular adapter holding tab 108. The free end portions 118 of the adapter cut line 116 are connected to each other via an adapter holding tab base line 120. The two adapter holding tab base lines 120 of the two adapter holding tabs 108 are slightly obliquely inclined away from each other in the direction towards the adapter clearance, and thus not parallel to the adapter holding longitudinal axis 114. Alternatively and also preferably, the two adapter holding tab base lines 120 extend parallel to each other, in particular also parallel to the carrier edge segments 88.
[0115] The holding tab base line 70 of the holding tab 60 forming the holding element 38a runs parallel to the adapter holding longitudinal axis 114.
[0116] As already explained, the adapter recess 84 is configured adjacent to the adapter holding device 104 starting from the carrier edge 56. By providing the adapter recess 84, a portion of the carrier 34 is missing, which is limited by the extension of the carrier edge sections 86 and 88 in the direction of the corner 82.
[0117] Furthermore, the supply device 10 comprises a balloon holding device 122 for the balloon 24, which is arranged or configured in the region of the second end 18 of the catheter 12. The balloon holding device 122 defines a balloon holding longitudinal axis 124. The balloon holding device 122 is configured asymmetrically with respect to the balloon holding longitudinal axis 124. The balloon holding device comprises two balloon holding elements 126a and 126b.
[0118] The two jointly acting balloon holding elements 126a and 126b are configured in the form of balloon holding tabs 128a and 128b. In the undeformed initial position of the supply device 10, i.e. only when the cutouts for configuring the balloon holding tabs are provided at the carrier, the free balloon holding tab ends 130a and 130b of the balloon holding tabs 128a and 128b point in the same direction. This is schematically represented in Figure 7 The free balloon holding tab ends 130a and 130b point in the direction of the carrier edge section 88.
[0119] The balloon holding tabs 128a and 128b are configured by balloon holding cut lines 132a and 132b at the carrier 34. The free ends 134a and 134b of the balloon holding cut lines 132a and 132b are connected to each other by a balloon holding tab base line 136a or 136b. The free balloon holding tab lengths 138a and 138b are defined by the distance of the free balloon holding tab ends 130a and 130b from the respective balloon holding tab base line 136a or 136b.
[0120] The balloon holding cut lines 132a and 132b are configured curved, i.e. in the shape of a circular arc section.
[0121] The two balloon holding tab base lines 136a or 136b run parallel to each other and parallel to the balloon holding longitudinal axis 124.
[0122] The two co-acting balloon holding tabs 128a and 128b have balloon holding cut lines 132a and 132b which are not equally long and, in addition, have different radii of curvature. The balloon holding cut line 132a is longer than the balloon holding cut line 132b. In contrast, the balloon holding cut line 132b is more strongly curved than the balloon holding cut line 132a. Thus, the radius of curvature of the balloon holding cut line 132b is smaller than the radius of curvature of the balloon holding cut line 132a. Nonetheless, the two balloon holding tab lengths 138a and 138b of the two balloon holding tabs 128a and 128b are essentially identical.
[0123] In addition, the holding tab base line 70 of the holding tab 60 forming the holding element 38c is oriented parallel to the balloon holding longitudinal axis 124. In this way, the second end portion of the catheter 12 can be guided tangentially away from the winding region to the balloon holding device 122.
[0124] In addition, the supply device 10 comprises a tip recess 140. The tip recess is configured in the form of a perforation 142 at the carrier 34. The tip recess 140 is positioned adjacent to the balloon holding device 122 in the direction of the balloon holding longitudinal axis 124, i.e. in the region of the corner 76. The balloon holding longitudinal axis 124 is directed in the direction of the carrier edge section 86.
[0125] As Figure 1 is shown schematically, the second end portion 18 of the catheter 12 is positioned in the region of the tip recess 140 in the storage position.
[0126] In addition, the tip recess 140 is dimensioned in such a way that the user can grasp the second end portion 18 of the catheter 12 held at the carrier 34 with two fingers.
[0127] In addition, a removal recess 144 is arranged or configured at the carrier 34. In the storage position as shown schematically in Figure 1 , at least two (in the embodiment shown three) catheter sections or windings of the catheter 12 held wound at the carrier 34 extend in the region of the removal recess 144.
[0128] The removal recess 144 is configured in the form of a perforation 146 at the carrier 34. The removal recess is hole-shaped, i.e. is shaped in the shape of a circular segment 150.
[0129] The centre line 148 of the circular segment 150 has a curvature which approximately corresponds to the curvature of the wound catheter 12 held at the supply device 10 in the storage position, as shown schematically in Figure 1 .
[0130] The circular segment 150 extends over an angular range 152 of about 30° to about 60°. In particular, the angular range can be about 40° to about 50°. In the embodiment shown in the figures, the angular range extends over about 45°.
[0131] The removal notch 144 has a width 154 in the radial direction with respect to the center point 50 of the holding circle. The width 154 is dimensioned such that it enables the flat holding of the catheter 12 at the carrier 34 with two fingers, namely the thumb 156 and the index finger 158, as schematically shown in Figure 11
[0132] Furthermore, the removal notch 144 is positioned on the holding circle 48, i.e. between two holding elements 38a and 38c which have the greatest angular distance from one another, as already described above. The circular segment 150 can comprise a section of the holding circle 48.
[0133] Furthermore, the supply device 10 comprises a guide wire holding device 160 for holding the end portion 32 of the guide wire 28 which protrudes from the guide wire channel. In the embodiment shown in the figures, the guide wire holding device is positioned in the region between the holding element 38a and the adapter holding device 104.
[0134] The guide wire holding device 160 comprises a guide wire holding element 162. The guide wire holding element 162 is configured in the form of a guide wire holding tab 164. A free guide wire holding tab end portion 166 of the guide wire holding tab 164 is oriented pointing in the direction of the carrier center 64.
[0135] For the configuration of the guide wire holding tab 164, a guide wire holding cut line 168 is configured at the carrier 34. The guide wire holding tab 164 defines a guide wire holding tab base line 170. The guide wire holding tab base line connects the free end portions 172 of the guide wire holding cut line 168 to one another. A guide wire holding tab length 174 of the guide wire holding tab 164 is defined by the distance of the guide wire holding tab end portion 166 from the guide wire holding tab base line 170.
[0136] Furthermore, the supply device 10 comprises a data storage element 176 for storing characteristic data of the catheter 12 held at the supply device 10. The characteristic data of the catheter are in particular its length, catheter sheath diameter, inflation pressure and balloon diameter, wherein the balloon diameter can be given depending on the inflation pressure.
[0137] The data storage element 176 is configured in the form of a printed data area 178, i.e. on the front side 42 of the carrier 34. The data storage element 176 is visually readable. The characteristic data are printed in Latin letters, such that the characteristic data can be directly read by the user.
[0138] The holding elements 38a, 38b and 38c extend over a circumferential angle 180 of approximately 10°. This circumferential angle is defined by the opening angle from the holding circle center point 50 to the free end 68 of the holding cut 66. In this way, the holding elements 38a, 38b and 38c can hold the coiled catheter 12 over a circumferential angle 180 of approximately 10°, respectively.
[0139] On the rear side 44, operating instructions 182 for using the supply device 10 and for operating the supply device and the catheter 12 are printed. Here, this is a graphic representation of the Figures 9 to 14
[0140] The special design of the supply device 10 enables three different options for taking the catheter 12 out of the carrier 34. Figure 9 A first variant is shown. Here, the user grasps the carrier 34 with his right hand in the area of the adapter holding device 104 and thereby also holds the coupling adapter 20. Now, the user can grasp the second end 18 of the catheter 12 with his other hand and take the catheter 12 turn by turn out of the carrier 34. In particular, the user can also leave the catheter 12 to such an extent on the carrier 34 that only the section of the catheter 12 comprising the guidewire channel is taken out of the carrier 34. Figure 10 It is shown how the coupling adapter 20 remains at the adapter holding device 104 but has been coupled with the flushing device. Furthermore, the protective sheath 26 can be pulled off the second end 18 in a simple manner when the second end 18 has been loosened from the carrier 34.
[0141] Furthermore, according to a second variant, the supply device 10 also enables the disengagement of the coiled catheter 12 from the three holding elements 38a, 38b and 38c without taking the catheter 12 into the stretched form. For this purpose, the user only needs to grasp the catheter 12 with two fingers (exemplarily shown in Figure 11 thumb 156 and index finger 158) in the area of the extraction notch 144. If the user holds the carrier 34 with his other hand in the area of the corner 78, the user can pull the coiled catheter 12 as a whole. In order to prevent the catheter 12 from uncoiling, the user now only has to wrap the first end 16 with the coupling adapter 20 twice around the coiled catheter 12 as schematically shown in Figure 12
[0142] In Figure 13 and Figure 14 A third option for taking the catheter 12 off the supply device 10 is schematically shown in Fig. 6. Here, the user grasps the second end portion 18 by reaching into the tip notch 140 with one hand. The user holds the coupling adapter 20 with the carrier 34 with the other hand. If the user pulls at the second end portion 18 in the direction of the arrow to the left, the catheter 12 unfolds and the user can hold the catheter 12 stretched straight between the two hands.
[0143] In the design variant described in the figures, the catheter 12 is held at the supply device 10 in the storage position such that the first end portion 16 and the second end portion 18 are oriented transversely, i.e. perpendicularly, to the carrier edge 56, i.e. the carrier edge section 86.
[0144] Optionally, the three holding elements 38a, 38b and 38c can each comprise a plurality of fold lines 184 running parallel to one another and parallel to the holding tab base line 70. This enables the holding tab 60 to be folded or bent along the fold lines such that the holding tab extends arched and arched overlaps the coiled catheter 12.
[0145] The two balloon holding tabs 128a and 128b are used as follows for holding the catheter 12 in the region of the balloon 24. The balloon holding tab 128b is folded over the balloon holding tab base line 136b in the direction of the balloon holding tab 128a, but the balloon holding tab is not folded or bent along the balloon holding tab base line 136b relative to the carrier 34. The balloon holding tab is pushed with the free balloon holding tab end 130b under the balloon holding tab 128a. Due to the slightly elastic properties of the material from which the carrier 34 is constructed, the balloon holding tab 128a is pressed slightly away from the front side 42, so that the balloon holding tabs 128a and 128b together span the balloon 24 arched, as this is schematically shown in Fig. 6. Figure 4
[0146] The described supply device enables the catheter 12 to be stored flat on the front side 42 of the carrier 34. In this way, inter alia, a maximum flat storage of the catheter 12 is achieved.
[0147] Furthermore, the supply device allows the three removal variants as described above.
[0148] If the second end portion is taken off the carrier 34, the protective sheath 26 and the guide wire 28 can be removed. The catheter 12 can be threaded onto the actual guide guide wire for the medical procedure and then introduced into the guide catheter.
[0149] A further advantage of the described supply device 10 is that the carrier 34 remains until the catheter 12 is finally taken up at the carrier 34, in particular until the coupling adapter 20 is removed from the adapter holding device 104, and the user can always see directly all information about the catheter 12 used by him, since the data area 178 continues to be coupled with the catheter 12 via the coupling adapter 20.
