Definitions
- the present invention relates to an anastomosis device, more particularly, the SCREW-DEVICE is capable of anastomosing the end of a blood vessel to the side of another blood vessel (end to side—see FIG. 1 ) or the side of a blood vessel to the side of another blood vessel (side to side—see FIG. 2 ).
- PHARMICOTHERAPY and SURGERY have been practised.
- Pharmacotherapy is useful for treatment at the initial stage but not when there is further progression of the disease, leading to occlusion of the vessel and eventually to an infarct (of the heart, brain, kidney, etc.).
- stents which can expand the occluded vessel in heart surgery (coronary artery)and in vascular surgery (stenosis of the carotic artery); stents remodelling aneurysma of the aorta abdominalis ; and recently the brain stents remodelling fusiform aneurysma of the basilar artery.
- vascular surgery we have, secondly, the revascularisation operations, viz. anastomosis and bypass operations. These revascularisation operations are carried out when there is (risk of) ischaemia, (risk of) infarct (of the heart, brain, limb, etc).
- Bypass procedures in general vascular surgery in heart surgery (coronary bypass), and in neurosurgery want to bypass huge vascular malformations (giant aneurysmas).
- bypass operations want to avoid the risk of brain-infarct after and/or before removing the tumour.
- the graft can be an arterial graft (in the case of heart surgery it would be the lima, or rima; in the case of neurosurgery, it would be the temporal artery or the occipital artery), or a venous graft (v.s.m), or even prosthetic material.
- arterial graft in the case of heart surgery it would be the lima, or rima; in the case of neurosurgery, it would be the temporal artery or the occipital artery
- v.s.m venous graft
- the object was to invent a really easy and extremely quick way to perform vascular anastomosis.
- the present invention provides a device capable of anastomosing the side of a vessel to another vessel (side to side) or the end of a vessel to the side of another vessel (end to side) without use of a suture. As a result there is a perfectly smooth joint without any creases in the vessel wall.
- the SCREW-DEVICE is very easy to apply on the vessel wall, it takes only a few seconds to screw the SCREW-DEVICE into the vessel wall of the receptor vessel and to screw it into the donor vessel. This procedure can also be reversed, screwing the device into the donor vessel and screwing this onto the receptor vessel.
- the opening of the receptor vessel wall can be done without occlusion of the receptor vessel or with a temporary occlusion of the receptor vessel. It can easily be combined with existing laser technologies for opening the receptor vessel in a non-occlusive manner.
- Form There are five main forms.
- the sharp end is round, i.e., non-cutting but capable of perforating the vessel wall.
- the sharp, round point is bent inwardly and downwardly in an angle of 10 to 20 degrees (a) (see FIG. 3 a, 3 b, 3 c, 3 d ).
- this sharp, round, non-cutting point may bend downwardly in an angle of 90 degrees (a).
- the end resembles a corkscrew, but the end is not situated in the middle of the final winding but rather on the periphery.
- This device is a spring with four to six windings guaranteeing elasticity.
- the first three windings are closely adjacent, i.e., there is just the smallest space between them (the space enabling the SCREW-DEVICE to dig itself into the vessel wall).
- the DOUBLE-ENDED SCREW-DEVICE/RING-FORM takes the form of a ring with two sharp, round, non-cutting points, pointing in the same direction but 180 degrees apart from each other (see FIG. 4 a, 4 b, 4 c ). These two points are bent inwardly and downwardly in an angle of 10 to 20 degrees. Alternatively, these sharp, round, non-cutting points may bend downwardly in an angle of 90 degrees. In this case, they resemble a corkscrew, but the ends are not situated in the middle of the final winding but rather on the periphery.
- the other end of the DOUBLE-ENDED SCREW-DEVICE is blunt
- This device is a spring with four to six windings guaranteeing elasticity.
- the first three windings are closely adjacent. i.e., there is just the smallest space between them (the s p ace enablin g the SCREW-DEVICE to dig itself into the vessel wall).
- the DOUBLE-ENDED SCREW-DEVICE/SPIRAL-FORM consists of two sharp, round, non-cutting points, the first coming from the end, the second coming from the beginning but bent in such a way as to align itself with the other sharp point (see FIG. 5 a, 5 b ). Again, these two points point in the same direction but stand 180 degrees apart from each other. They bend inwardly and downwardly in an angle of 10 to 20 degrees.
- these sharp, round, non-cutting point may bend downwardly in an angle of 90 degrees.
- the end resembles a cork-screw, but the ends are not situated in the middle of the final winding but rather on the periphery.
- This device consists of two to three windings, resembling a key-ring.
- On the one end there is a sharp, round, non-cutting point, bending inwardly and downwardly in an angle of 10 to 20 degrees. Alternatively, this point may bend downwardly in an angle of 90 degrees.
- the end resembles a cork-screw, but the end is not situated in the middle of the final winding but rather on the periphery.
- the other end is blunt. Where the two ends meet, there is a twist in the ring (see FIG. 6 a, 6 b ).
- This device consists of two basic parts, the removable head (with applicator) and a hollow screw of three windings, which remains in place (i.e., in the blood-vessel).
- the hole in the vessel wall can be made by traditional means—basically: the occlusive manner using a surgical knife, or the non-occlusive manner using a laser—or by means of a SCREW-CUTTER.
- This specially designed device operates in a non-occlusive manner. It takes the form of a hollow cylinder in which a long shaft with a handle on top moves up and down (see FIG. 8 a, 8 b ). This shaft ends in a screw consisting of three windings. The first two of these take the form of a cork-screw, so that the sharp point is in the middle.
- the third winding has its sharp edges pointing downward, whereas the first two windings are horizontal, like in an ordinary screw (see FIG. 8 c ).
- the diameter of the five SCREW-DEVICES may vary-from 1 millimetre to plus 2 centimetre.
- the SCREW-DEVICE is made of inox material, or titanium, or super-elastic materials such as nitinol, or synthetic materials, or even resorbable materials.
- the material may vary from 0.1 mm to any desirable thickness.
- the donor vessel is clamped and opened.
- the SCREW-DEVICE is screwed into and through the vessel wall, thus perforating the donor vessel with two windings.
- the SCREW-DEVICE can be used in an occlusive or non-occlusive manner, depending on the preferences of the surgeon.
- the SCREW-DEVICE can be manufactured commercially and be employed to anastomose two vessels of different or identical sizes. It can be used in all domains of vascular surgery, heart surgery, and neurosurgery.

Abstract
The present invention, the screw-device, is a mechanical device for anastomosing hollow tube-like structures in the human body, such as blood vessels, bowels and ureters. It is thus not restricted to (micro-)vessels. It can be used in every surgical operation dealing with anastomosis and bypass operations. It allows anastomosing end to side or side to side. The screw-device is very easy to apply onto the vessel wall. Screwing is a fast technique saving operating time and requiring only basic microsurgical skills. The manufacturing is easy. Another advantage is that the screw-device can be mounted onto the receptor vessel without first opening and/or occluding this vessel. Later on, the receptor vessel wall can be opened with laser or scalpel. It should be understood that the foregoing is illustrative and not limiting, and that modifications may be made by those skilled in the art, without departing from the scope of the invention.
Description
- This application is a continuation of PCT application no. PCT/BE2003/000126, designating the United States and filed Jul. 22, 2003; which claims the benefit of the filing date of PCT application no. PCT/BE03/00074, filed Apr. 28, 2003, both of which are hereby incorporated herein by reference.
- 1. Technical Field
- The present invention relates to an anastomosis device, more particularly, the SCREW-DEVICE is capable of anastomosing the end of a blood vessel to the side of another blood vessel (end to side—see
FIG. 1 ) or the side of a blood vessel to the side of another blood vessel (side to side—seeFIG. 2 ). - Vital Cells (in brain, heart, muscles, organs) demand nutrition, oxygen, energy (glucose) at a constant supply. These components are found in the blood which runs in a healthy vascular system. As a pump system, the heart ensures the circulation of the blood(nutrients) through the body. When there is a discrepancy between demand of oxygen or nutrients to the cell and the delivery capacity of the bloodstream to the cell, there is cell damage or even cell death. in some vital organs this warm ischemia before cell death is very short. For brain cells, death occurs after 3 minutes. The reason for this insufficiency is mostly a vascular disease (arteriosclerosis), stenosis, occlusion of small or large vessels, or a heart problem (coronary disease). Most important risk factors of arteriosclerosis are: hypertension, elevated serum lipids, cigarette smoking, diabetes mellitus, decreased physical activity and obesitas (i.e., consuming more calories than those expended as energy).
- To treat a clogged or occluded blood vessel, PHARMICOTHERAPY and SURGERY have been practised. Pharmacotherapy is useful for treatment at the initial stage but not when there is further progression of the disease, leading to occlusion of the vessel and eventually to an infarct (of the heart, brain, kidney, etc.).
- The medical diagnostic tools and the technical developments available to the doctor have increased enormously, MRI-, MRA.-, CT- and CTA- scan. This has enabled an early diagnosis and a more successful treatment of patients with vascular diseases.
- In vascular surgery we have, firstly, the endovascular procedures, for example: stents, which can expand the occluded vessel in heart surgery (coronary artery)and in vascular surgery (stenosis of the carotic artery); stents remodelling aneurysma of the aorta abdominalis; and recently the brain stents remodelling fusiform aneurysma of the basilar artery.
- In vascular surgery we have, secondly, the revascularisation operations, viz. anastomosis and bypass operations. These revascularisation operations are carried out when there is (risk of) ischaemia, (risk of) infarct (of the heart, brain, limb, etc). Bypass procedures in general vascular surgery, in heart surgery (coronary bypass), and in neurosurgery want to bypass huge vascular malformations (giant aneurysmas). In tumor surgery, bypass operations want to avoid the risk of brain-infarct after and/or before removing the tumour.
- The graft can be an arterial graft (in the case of heart surgery it would be the lima, or rima; in the case of neurosurgery, it would be the temporal artery or the occipital artery), or a venous graft (v.s.m), or even prosthetic material. These highly complex operations require a competent surgical team, delicate instruments, advanced microsurgical equipment, magnifying loops, or—for neurosurgeons—an operating microscope.
- In microvascular surgery, ultra fine suture material is used to suture the blood vessels onto each other (anastomosis). This technique of suturing is time consuming and it demands extremely advanced microsurgical skills. Moreover, it never results in a completely smooth joint, the stitches producing microscopic creases in the vessel wall. Various methods have been developed to perform anastomosis with mechanical devices in a short time without suturing. Most of these devices are complex and time-consuming to apply (for example, in brain-surgery, a microvascular anastomosis takes on average, twenty to thirty minutes). During this time, there is a high risk of bleeding and infection in all forms of microvascular surgery mentioned above. Reducing this time is of the utmost importance for the well-being of the patient.
- The object was to invent a really easy and extremely quick way to perform vascular anastomosis.
- The present invention, the SCREW-DEVICE, provides a device capable of anastomosing the side of a vessel to another vessel (side to side) or the end of a vessel to the side of another vessel (end to side) without use of a suture. As a result there is a perfectly smooth joint without any creases in the vessel wall.
- The SCREW-DEVICE is very easy to apply on the vessel wall, it takes only a few seconds to screw the SCREW-DEVICE into the vessel wall of the receptor vessel and to screw it into the donor vessel. This procedure can also be reversed, screwing the device into the donor vessel and screwing this onto the receptor vessel.
- It can be used in every surgical operation dealing with vascular problems, like anastomosis or bypass operations done in vascular surgery, heart surgery and neurosurgery.
- The opening of the receptor vessel wall can be done without occlusion of the receptor vessel or with a temporary occlusion of the receptor vessel. It can easily be combined with existing laser technologies for opening the receptor vessel in a non-occlusive manner.
- Form: There are five main forms.
- 1. Single-Ended Screw-Device.
- This device is a spring with four to six windings guaranteeing elasticity. The first three windings are closely adjacent, i.e., there is just the smallest space between them (the space enabling the SCREW-DEVICE to dig itself into the vessel wall). On the one end of the SINGLE-ENDED SCREW-DEVICE there is an extremely sharp end, meant to perforate the vessel wall. The other end is blunt.
- The sharp end is round, i.e., non-cutting but capable of perforating the vessel wall. The sharp, round point is bent inwardly and downwardly in an angle of 10 to 20 degrees (a) (see
FIG. 3 a, 3 b, 3 c, 3 d). Alternatively, this sharp, round, non-cutting point may bend downwardly in an angle of 90 degrees (a). In this case, the end resembles a corkscrew, but the end is not situated in the middle of the final winding but rather on the periphery. - 2. Double-Ended Screw-Device/Ring-Form.
- This device is a spring with four to six windings guaranteeing elasticity. The first three windings are closely adjacent, i.e., there is just the smallest space between them (the space enabling the SCREW-DEVICE to dig itself into the vessel wall). On the one end the DOUBLE-ENDED SCREW-DEVICE/RING-FORM takes the form of a ring with two sharp, round, non-cutting points, pointing in the same direction but 180 degrees apart from each other (see
FIG. 4 a, 4 b, 4 c). These two points are bent inwardly and downwardly in an angle of 10 to 20 degrees. Alternatively, these sharp, round, non-cutting points may bend downwardly in an angle of 90 degrees. In this case, they resemble a corkscrew, but the ends are not situated in the middle of the final winding but rather on the periphery. The other end of the DOUBLE-ENDED SCREW-DEVICE is blunt - 3. Double-Ended Screw-Device/Spiral Form.
- This device is a spring with four to six windings guaranteeing elasticity. The first three windings are closely adjacent. i.e., there is just the smallest space between them (the space enabling the SCREW-DEVICE to dig itself into the vessel wall). The DOUBLE-ENDED SCREW-DEVICE/SPIRAL-FORM consists of two sharp, round, non-cutting points, the first coming from the end, the second coming from the beginning but bent in such a way as to align itself with the other sharp point (see
FIG. 5 a, 5 b). Again, these two points point in the same direction but stand 180 degrees apart from each other. They bend inwardly and downwardly in an angle of 10 to 20 degrees. Alternatively, these sharp, round, non-cutting point may bend downwardly in an angle of 90 degrees. In this case, the end resembles a cork-screw, but the ends are not situated in the middle of the final winding but rather on the periphery. - 4. Key-Ring Screw-Device.
- This device consists of two to three windings, resembling a key-ring. On the one end, there is a sharp, round, non-cutting point, bending inwardly and downwardly in an angle of 10 to 20 degrees. Alternatively, this point may bend downwardly in an angle of 90 degrees. In this case, the end resembles a cork-screw, but the end is not situated in the middle of the final winding but rather on the periphery. The other end is blunt. Where the two ends meet, there is a twist in the ring (see
FIG. 6 a, 6 b). - 5. Screw-Device With Removable Head.
- This device consists of two basic parts, the removable head (with applicator) and a hollow screw of three windings, which remains in place (i.e., in the blood-vessel).
-
- 5.1. The head consists of two windings, and ends in the form of a cork-screw (see
FIG. 7 a, 7 b). This is, again, a round, sharp, non-cutting point. The head forms one whole with the applicator, i.e., a long, thin shaft with a handle used to drill the head into the vessel wall. Once the head is in place (i.e., in the middle of the vessel (seeFIG. 7 c), it is removed—together with the applicator—from the rest of the SCREW-DEVICE that stays within the vessel wall. - 5.2. The other part of the SCREW-DEVICE consists of three hollow windings attached to the head by means of internal, anti-clockwise windings (see
FIG. 7 d). Every winding is wider than the previous one, thus expanding the vessel wall and the opening in it made by the head. This opening is made in a non-occlusive way, i.e., the receptor vessel need not be temporarily occluded.
- 5.1. The head consists of two windings, and ends in the form of a cork-screw (see
- Additional Tool.
- In the fifth form, i.e., the SCREW-DEVICE WITH REMOVABLE HEAD, no additional tools are needed to open the vessel wall.
- In the other forms, the hole in the vessel wall can be made by traditional means—basically: the occlusive manner using a surgical knife, or the non-occlusive manner using a laser—or by means of a SCREW-CUTTER. This specially designed device operates in a non-occlusive manner. It takes the form of a hollow cylinder in which a long shaft with a handle on top moves up and down (see
FIG. 8 a, 8 b). This shaft ends in a screw consisting of three windings. The first two of these take the form of a cork-screw, so that the sharp point is in the middle. They keep the vessel wall in its place, whereas the third winding—forming a full circle of 360 degrees—actually cuts and removes the part of the vessel wall where the hole is to be made. The third winding has its sharp edges pointing downward, whereas the first two windings are horizontal, like in an ordinary screw (seeFIG. 8 c). - Diameter:
- Depending on the sort of blood-vessel, the diameter of the five SCREW-DEVICES may vary-from 1 millimetre to plus 2 centimetre.
- Substance:
- The SCREW-DEVICE is made of inox material, or titanium, or super-elastic materials such as nitinol, or synthetic materials, or even resorbable materials.
- Thickness of material:
- Depending on the diameter of the blood-vessel, the material may vary from 0.1 mm to any desirable thickness.
- Elasticity:
- Depending on the material.
- A. For the first four forms of the SCREW-DEVICE—that is: SINGLE-ENDED SCREW-DEVICE, DOUBLE-ENDED SCREW-DEVICE/RING-FORM, DOUBLE-ENDED SCREW-DEVICE/SPIRAL-FORM, KEY-RING SCREW-DEVICE—the technique is as follows:
-
- 1. End-to-side
- In the first step, the receptor vessel is exposed by means of the techniques current in vascular surgery. When a venous graft is used end-to-side, the SCREW-DEVICE is screwed into the graft (donor vessel) or sutured to the donor vessel.
- In the second step, the donor vessel containing the SCREW-DEVICE is screwed into the receptor vessel.
- Alternatively, the SCREW-DEVICE can first be screwed into the receptor vessel and then the donor vessel can be attached to it.
- The SCREW-DEVICE is turned into the vessel clock-wise and completes only one turn, that is: it is in its proper place after 360 degrees.
- In the third step, the wall of the receptor vessel is opened by means of existing techniques, such as laser or the surgical knife.
- 2. Side-to-side
- First, the donor vessel is clamped and opened. The SCREW-DEVICE is screwed into and through the vessel wall, thus perforating the donor vessel with two windings.
- These windings are then screwed into the receptor vessel (clockwise and 360 degrees).A hole is then made into the receptor vessel wall by means of existing techniques, such as laser or the surgical
- B. For the fifth form, that is the SCREW-DEVICE WITH REMOVABLE HEAD, the techniques mentioned sub A are applied in the same way, but they are followed by the removal of the head.
- In all these forms, the SCREW-DEVICE can be used in an occlusive or non-occlusive manner, depending on the preferences of the surgeon.
- The SCREW-DEVICE can be manufactured commercially and be employed to anastomose two vessels of different or identical sizes. It can be used in all domains of vascular surgery, heart surgery, and neurosurgery.
