Abstract

A method for tensioning incisions made in a target vessel during an anastomosis procedure is provided. After an incision is made in a target vessel, incision tensioners are placed within the incision in order to tension the incision. The incision is tensioned when the incision tensioners are pulled taut in order to stretch the incision to a predetermined length or a predetermined force. The tensioners allow for proper grafting of a graft vessel to the target vessel in an end to side anastomosis. In addition, the incision tensioners allow the incision to have a known geometry, thereby allowing precise grafting of the graft vessel to the target vessel during the anastomosis procedure. After the incision is tensioned, the graft vessel is grafted to the target vessel using clips, sutures, staples or other anastomosis devices. One example of anastomosis clips are configured to capture the graft vessel and the target vessel such that the graft vessel grafts with the target vessel.

Description

    BACKGROUND OF THE INVENTION
  • [0001]
    1. Field of the Invention
  • [0002]
    The present invention relates generally to preparing blood vessels for a vascular anastomosis procedure and more particularly to a system and method for forming and holding precise incisions in a target vessel.
  • [0003]
    2. Description of Related Art
  • [0004]
    Vascular anastomosis is a procedure where two separate blood vessels of a patient are surgically grafted together. The vascular anastomosis procedure is routinely performed during the treatment of a variety of conditions, including coronary artery disease, diseases of the great and peripheral vessels, organ transplantation and other types of trauma. When a patient suffers from coronary artery disease (CAD), an occlusion or stenosis in a coronary artery restricts blood flow to the heart muscle. In order to treat CAD, the area where the occlusion occurs is bypassed. The area is bypassed through rerouting blood flow by grafting a vessel in the form of either a prosthesis, a harvested artery or a vein. When the vessel is grafted to bypass the blocked coronary artery, the occlusion is avoided and adequate blood flow is restored to the heart muscle. This treatment is known as coronary artery bypass grafting (CABG).
  • [0005]
    When a CABG is performed, a large incision is made in the chest of a patient and the sternum is separated in order to allow access to the heart of the patient. Moreover, the patient is connected to a heart lung machine which circulates the blood of the patient. After the heart lung machine is connected to the patient, the patient's heart is stopped in order to perform the vascular anastomosis. However, stopping the patient's heart is very traumatic to the patient.
  • [0006]
    In order to minimize the trauma to the patient induced by the CABG, less invasive techniques have been used. These less invasive techniques include performing a series of small incisions in the patient's chest. Once the incisions are completed, surgery is performed with the aid of visualizing scopes. The less invasive techniques may be performed on a beating heart in order minimize trauma to the patient, thereby avoiding the need for cardiopulmonary bypass.
  • [0007]
    In both the conventional and less invasive CABG techniques, a surgeon makes an incision in a coronary artery in order to allow grafting of a graft vessel to the coronary artery. However, as the surgeon makes an incision in the coronary artery, an incision without a definable geometry results, as shown with respect to FIG. 1. FIG. 1 is a schematic of a top view of a coronary artery 102 after the formation of an incision by a surgeon in accordance with the prior art. During both the conventional and less invasive CABG techniques, a surgeon forms an incision 104 in the coronary artery 102 as shown with respect to FIG. 1. As those skilled in the art will appreciate, the incision 104 includes walls 104 a and 104 b which do not define a geometry. The imprecise geometry of the incision 104, as illustrated by the walls 104 a and 104 b, make grafting a graft vessel to the coronary artery 102 difficult.
  • [0008]
    In addition, as may be seen with respect to FIG. 1, the incision 104 is not held in place. Instead, the geometry of the incision 104 is dictated by the orientation of the coronary artery 102. To further illustrate, if the coronary artery 102 shifts during an anastomotic procedure, the geometry of the incision 104 changes, thereby making grafting even more difficult. As a result, suturing a graft vessel to the coronary artery requires a greater amount of time and surgical skill, thereby increasing the overall cost to perform an anastomotic procedure.
  • [0009]
    Furthermore, once the surgeon makes the incision 104 in the coronary artery 102, the surgeon must suture a graft vessel to the coronary artery 102. Typically, the surgeon sutures the graft vessel to the coronary artery by hand sewing the vessel using a needle the size of an eyelash. As may be appreciated, this technique requires a great amount of skill on the part of the surgeon and a great amount of time. Thus, both the time and financial costs are greatly increased for the patient. In addition, during both the conventional techniques and the less-invasive techniques, the possibility of trauma to the patient is further increased due to the greater amount of time required to perform the surgery.
  • [0010]
    In addition to suturing, other methods used during an anastomosis to graft a graft vessel to a coronary artery involves the use of an automated anastomosis instrument. However, when an automated anastomosis instrument is used, accurate location of the tissue is important to achieve accurate and leak-proof grafting.
  • [0011]
    Accordingly, a need exists for a method to form and hold incisions having a definable geometry in order to allow precise grafting of a graft vessel to a target vessel. This new method should minimize the time associated with grafting a graft vessel to a target vessel, thereby decreasing the possibility of trauma to a patient resulting from a long anastomotic procedure. Also, the new method should minimize the time associated with grafting a graft vessel to a target vessel by providing both a method allowing precise incisions in a target vessel and a simplified method for attaching the graft vessel to the target vessel once the incision is made.
  • BRIEF SUMMARY OF THE INVENTION
  • [0012]
    The present invention fills the aforementioned needs by providing a method for tensioning incisions in a target vessel. The present invention also provides a system for tensioning incisions in a target vessel such that the incisions have a known geometry with a predetermined length.
  • [0013]
    In one embodiment of the present invention, a method for grafting a graft vessel to a target vessel during an anastomosis procedure is disclosed. The method comprises forming an incision in the target vessel and placing incision tensioners within the incision. Upon placement of the incision tensioners within the incision, the incision tensioners tension the target vessel by pulling the incision taut. Once the incision is tensioned, the graft vessel is grafted to the target vessel using any suitable technique, including welding, clips, staples, or the like.
  • [0014]
    In a further embodiment of the present invention, a method for forming an incision in a target vessel for an anastomosis procedure is disclosed. The method comprises inserting a first incision tensioner and a second incision tensioner through a wall of the target vessel. After the incision tensioners are inserted in the wall of the target vessel, the first incision tensioner is separated from the second incision tensioner. When the first incision tensioner is separated from the second incision tensioner, the incision is tensioned to a predetermined length having a known geometry.
  • [0015]
    In another embodiment of the present invention, a system for grafting a graft vessel to a target vessel having an incision formed therein is disclosed. The system comprises first and second incision tensioners, a tensioning device body and a tensioning mechanism. The first and second incision tensioners are configured for placement within the incision of the target vessel. In addition, the incision tensioners are configured to tension the incision to a predetermined length having a known geometry once the incision tensioners are placed within the incision of the target vessel. The tensioning device body connects to both the first incision tensioner and the second incision tensioner with the tensioning mechanism. The tensioning mechanism moves the first incision tensioner with respect to the second incision tensioner in order to tension the incision in the target vessel.
  • [0016]
    As may be appreciated, the present invention provides a method for tensioning incisions to a predetermined length in a target vessel. In addition, the present invention provides a method for maintaining a known geometry of the incision during an anastomosis procedure. Therefore, the prior art problems associated with the an incision having a non-definable geometry are avoided. Furthermore, the predetermined length and the known geometry of the incisions allow for precise grafting of a graft vessel to the target vessel in a time efficient and cost efficient manner.

  • DETAILED DESCRIPTION OF THE INVENTION
  • [0042]
    A method for tensioning an incision on a target vessel during an anastomosis procedure is disclosed. The incision is tensioned in a target vessel in order to facilitate grafting of a vessel to the target vessel during the anastomosis procedure. Furthermore, the tensioned incision allows for proper aligning of a graft vessel with a target vessel. As used herein, an incision is tensioned when the incision is pulled taut. In accordance with another embodiment of the present invention, the incision may also be tensioned by stretching the incision with incision tensioners. The incision is pulled taut when the edges of the incision are substantially straight and parallel to one another, as will be described in much greater detail with respect to accompanying Figures. In addition, as will be further described with reference to the accompanying Figures, the incision tensioners may be any device suitable for pulling an incision taut, such as hooks, pins or the like.
  • [0043]
    Now making reference to the Figures, and more particularly to FIG. 2, FIG. 2 is a top view of the target vessel 202 after the formation of the incision 204. The incision 204 is formed in order to allow the grafting of a graft vessel (shown in FIG. 13) to the target vessel 202 at the point of the incision 204 in an end to side anastomosis. The incision 204 is formed using any suitable technique, such as punching a hole, or slicing with a scalpel, knife, shears or the like. Once the incision 204 is formed, the incision 204 is pulled taut as shown with reference to FIG. 3A.
  • [0044]
    [0044]FIG. 3A is a schematic showing a perspective view of the target vessel 202 shown with reference to FIG. 2, where the incision 204 is tensioned with an incision tensioning system 200. In one embodiment of the present invention, the incision tensioning system 200 aligns a graft vessel (shown with reference to FIG. 13) with the target vessel 202. The incision tensioning system 200 includes tensioners 222, a bracket 216 and hooks 206 a. The tensioners 222 provide a force to the hooks 206 a such that the hooks 206 a tension the incision 204. In accordance with one embodiment of the present invention, the tensioners 222 may be any device suitable for providing a tensioning force on the hooks 206A such as a spring, a threaded fastener, or the like. The bracket 216 provides structural support for the tensioners 222 and the hooks 206 a such that the tensioners 222 provide a tensioning force to the hooks 206 a in order to tension the incision 204.
  • [0045]
    The hooks 206 a are inserted into ends of the incision 204, as shown with reference to the Figure. The hooks 206 a are configured to engage the ends of the incision 204 such that the hooks 206 a pull the incision 204 taut to form a known geometry in which the sides of the incision 204 are substantially straight and parallel, as shown with respect to FIG. 3A. In accordance with one embodiment of the present invention, the known geometry is defined as the ability of the geometry of the incision 204 to remain constant during an anastomosis procedure. As described with reference to the prior art of FIG. 1, the prior art incisions formed in a target vessel were not pulled taut and did not have a known geometry. Therefore, the geometry of the prior art incision changes as a surgeon performs an anastomosis procedure, as opposed to the present invention.
  • [0046]
    In accordance with an embodiment of the present invention, the incision 204 is taut when the incision 204 is tensioned to a predetermined length X. The predetermined length X of the incision 204 corresponds to a width of a compressed graft vessel (shown with reference to FIG. 13) to be grafted to the target vessel 202 during the anastomosis procedure. When the incision 204 is tensioned to the predetermined length X, proper grafting of the graft vessel to the target vessel 202 is ensured. In one embodiment of the present invention, the incision 204 is tensioned by preferably stretching in a range between about 2% of the length of the incision 204 to about 25% of the length of the incision 204. For example, if the incision 204 has a predetermined length of 0.200 inches, the incision 204 is tensioned when the hooks 206 a stretch the incision to a predetermined length of 0.220 inches. Additionally, in accordance with another embodiment of the present invention, the hooks 206 a may be pulled with a predetermined force as denoted by directional arrows Y and Z. In one embodiment of the present invention, the pre-determined tensioning force is in a range preferably of about 0.001 N to about 4.5 N and more preferably about 0.65 N. Incision tensioning is provided by pulling on the hooks 206 a until the incision 204 is tensioned to the predetermined length X. The incision may be measured using any suitable technique to ascertain the proper length.
  • [0047]
    It should be noted that the hooks 206 a may have any configuration suitable for engaging ends of the incision 204, as shown with reference to FIG. 3B. FIG. 3B is a side view of alternative embodiments of the hooks 206 a as shown with reference to FIG. 3A, in accordance with one embodiment of the present invention. Hooks 206 a, 206 b and 206 c include ends 206 a-1, 206 b-1 and 206 c-1. The ends 206 a-1, 206 b-1 and 206 c-1 are configured to engage the incision 204 once the hooks 206 a, 206 b and 206 c are inserted in the incision 204, as shown with reference to FIG. 3A. Therefore, after the hooks 206 a, 206 b and 206 c are inserted in the incision 204, the ends 206 a-1, 206 b-1 and 206 c-1 engage tissue to pull the incision 204 taut. In addition to the hooks 206 a, 206 b and 206 c, pins 208 a may also be used to pull the incision 204 taut, as shown with reference to FIG. 4A.
  • [0048]
    [0048]FIG. 4A is a side view of the incision 204 shown with reference to FIG. 3A, where the pins 208 a are inserted in the incision 204 to tension the incision 204, in accordance with one embodiment of the present invention. As described with reference to FIG. 3A, the pins 208 a tension the incision 204 by pulling the incision 204 taut using the tensioners 222 until the incision 204 is tensioned to the predetermined length X. Alternatively, the pins 208 a may be pulled with a pre-determined force along the directional arrows Y and Z, as described with reference to FIG. 3A. In addition to the pins 208 a, any pin having a configuration suitable for pulling the incision 204 taut may be used to stretch the incision 204 to the predetermined length X, as shown with respect to FIG. 4B.
  • [0049]
    [0049]FIG. 4B shows pins 208 a, 208 b and 208 c which may be used to tension the incision 204 to the predetermined length X, in accordance with one embodiment of the present invention. The pins 208 b and 208 c include ends 208 b-1 and 208 c-1. The end 208 b-1 includes a groove 208 b-2 which is configured to engage the incision 204 as the pin 208 b is inserted into the incision 204. The end 208 c-1 is configured to engage the incision 204 as the pin 208 c is inserted into the incision 204. In addition to the pins 208 a through 208 c, sutures 210 a may be used to tension the incision 204 to the predetermined length X, as shown with reference to FIGS. 5A and 5B.
  • [0050]
    [0050]FIG. 5A illustrates a side view of the incision 204 shown with respect to FIG. 4A, where the sutures 210 a tension the incision 204 to the predetermined length X. In this embodiment, the sutures 210 a include ends 210 a-1 which are attached to the ends of the incision 204 and knotted in a conventional manner as shown with respect to FIG. 5A. Once the sutures 210 a are formed, the sutures 210 a pull the incision 204 taut in order to tension the incision 204. In addition to the knotted sutures 210 a, unknotted sutures 210 b, as shown with respect to FIG. 5B, may also be used to tension the incision 204 to the predetermined length X.
  • [0051]
    [0051]FIG. 5B illustrates a side view of the incision 204 shown with respect to FIG. 4A, where the sutures 210 b are used to tension the incision 204 to the predetermined length X. In this embodiment, the sutures 210 b are formed such that the sutures 210 b stet through ends of the incision 204, as shown with reference to FIG. 5B. Once the sutures 210 b are secured to the ends of the incision 204, the sutures are pulled taut to tension the incision 204 to the predetermined length X. In addition to the sutures 210 a and 210 b, a balloon assembly 212 may be used to tension the incision 204 to the predetermined length X, as shown with respect to FIG. 6A.
  • [0052]
    [0052]FIG. 6A shows a side view of the incision 204 shown with reference to FIG. 5B, where the balloon assembly 212 tensions the incision 204 to the predetermined length X. The balloon assembly 212 includes a balloon 212 a rigidly coupled with a member 212 b, as shown with reference to FIG. 6B. When the balloons assemblies 212 are inserted into the incision 204, the balloons 212 a are in an uninflated configuration in order to facilitate placement within the incision 204. Once the balloons 212 a are placed within the incision 204, the balloons 212 a are inflated using any suitable technique. Upon inflation, the balloon assemblies 212 are used to tension the incision 204. The balloon assemblies 212 tension the incision 204 by pulling the balloon assemblies 212 taut within the incision 204 to tension the incision 204 into the predetermined length X, as shown with respect to FIG. 6A. It should also be noted that the balloon assemblies 212 may tension the incision 204 to the predetermined length X with the predetermined force, as previously described.
  • [0053]
    In addition to the balloons 212 a, a member 214 may also be used to tension the incision 204 to the predetermined length X, as shown with reference to FIG. 7A. Once the incision 204 is made, the member 214 is placed within the incision 204 in order to tension the incision to the predetermined length X, as shown with respect to FIG. 7A. The member 214 includes an anvil 214 a (shown with reference to FIG. 7B) which is configured for insertion in the incision 204 in order to tension the incision 204 to the predetermined length X. Thus, upon placement of the member 214 within the incision 204, the anvil 214 a tensions the incision 204 to the predetermined length X.
  • [0054]
    As previously stated, the incision 204 is formed using any suitable technique, such as slicing with a scalpel, knife, shears or the like. Nonetheless, in accordance with another embodiment of the present invention, the incision 204 may be tensioned by a hook 206 a′ configured to include a cutting surface 206 a′-2, as shown with reference to FIG. 8. FIG. 8 is a side view of the target vessel 202 shown with reference to FIG. 5A, where the hook 206 a′ includes the cutting surface 206 a′-2, in accordance with one embodiment of the present invention. The cutting surface 206 a′-2 is configured to form an incision in the target vessel 202 in order to allow tensioning of the incision 204 to the predetermined length X. In one embodiment of the present invention, the cutting surface 206 a′-2 may be any sharpened surface suitable for forming an incision in the target vessel 202, including a blade or the like. Once the hooks 206 a and 206 a′ are inserted into the target vessel 202, the hook 206 a′ moves away from the hook 206 a to form the incision 204, as shown with reference to FIG. 9.
  • [0055]

  • [0061]
    As previously mentioned with reference to FIG. 3A, a predetermined force may form the incision 204 to the predetermined length X. In accordance with one embodiment of the present invention, a force controlled tension device 224, as shown with respect to FIG. 14A, applies a predetermined force to the target vessel 202 in order to form the incision 204 to the predetermined length X. The force controller tension device 224 includes tensioners 226 and 228. The tensioners 226 and 228 are configured to engage the target vessel 202 with hooks 226 a and 228 a, as shown with reference to FIG. 14A. It should be noted that the tensioners 226 and 228 may also be pins, or any other device suitable for engaging the target vessel 202, as described earlier. Additionally, the tensioners 226 and 228 include removable sections 226 b and 228 b which allow for precise placement of the graft vessel 220 to the target vessel 202. The removable sections 226 b and 228 b are removed once the graft vessel 220 is placed over the removable sections 226 b and 228 b and the graft vessel 220 is brought into contact with tensioners 226 and 228, as will be discussed more fully with respect to FIGS. 15A and 15B.
  • [0062]
    In accordance with one embodiment of the present invention, the tensioner 228 engages with the tensioner 226 via a notch 228 c. The notch 228 c is configured such that the tensioner 228 slidably attaches to the tensioner 226, as shown in the Figure. The force controller tension device 224 also includes a spring 230 which imparts a force on the tensioner 228 in order to separate the tensioner 228 from the tensioner 226 upon insertion of the force controller tension device 224 within the target vessel 202, as shown with reference to FIG. 15A. The spring 230 may be any spring suitable for separating the tensioner 228 from the tensioner 226, such as a compression spring or the like. In accordance with one embodiment of the present invention, the spring 230 imparts a force preferably in a range of about 0.001 N to about 4.5 N and more preferably about 0.65 N. It should be noted that alternative techniques may be used to separate the tensioner 228 from the tensioner 226 in addition to the spring 230 using any suitable force applying mechanism, such as a torque applying DC motor or the like.
  • [0063]
    Turning to FIG. 15A, FIG. 15A illustrates the insertion of the force controller tension device 224 within the target vessel 202, in accordance with one embodiment of the present invention. Prior to insertion within the target vessel 202, the tensioners 226 and 228 are adjacent to one another to form a single unit as shown with reference to FIG. 14B. Upon insertion of the force controller tension device 224 within the target vessel 202, the spring 230 moves the tensioner 228 in the direction Z in order to form the incision 204 to the predetermined length X, as shown with reference to FIG. 15B. In one embodiment of the present invention, once the force controller tension device 224 forms the incision 204 to the predetermined length X, the graft vessel 220 is placed over the removable sections 226 b and 228 b. The removable sections 226 b and 228 b are then removed in order to allow grafting of the graft vessel 220 to the target vessel 202 as shown with reference to FIG. 15B.
  • [0064]
    Now making reference to FIG. 16, FIG. 16 illustrates a method 300 for tensioning an incision in a target vessel, in accordance with one embodiment of the present invention. In an operation 302, an incision is made in a target vessel. The incision allows for grafting of a graft vessel to the target vessel during an end to side anastomosis procedure. Once the incision is made in the target vessel, incision tensioners are inserted into ends of the incision in an operation 304. The incision tensioners may include any structure suitable for providing tension to an incision, including the previously described anvil, hooks, pins, balloons and clips. For example, making reference to FIG. 3A, an incision 204 is made in the target vessel 202 in the operation 302. Once the incision is made, hooks 206 a are inserted into the incision. After insertion of the hooks 206 a, an operation 306 is performed.
  • [0065]
    In the operation 306, the incision tensioners pull the incision taut. In one embodiment of the present invention, the incision tensioners are considered taut when the incision is tensioned to a predetermined length. It should also be noted that when the incision tensioners are pulled taut, the tensioners maintain a known geometry of the incision. Turning back to the example and FIG. 3A, the hooks 206 a are pulled taut until the incision 204 is tensioned to the predetermined length X. As previously stated, the predetermined length X allows for proper grafting of a graft vessel to the target vessel during an anastomosis procedure by matching the incision length to a graft vessel size. Turning back to the method 300, once the incision tensioners pull the incision taut, a graft vessel is grafted to the target vessel at the incision site during an anastomosis procedure in an operation 308. The performed anastomosis procedure which connects the graft vessel to the target vessel may include suturing, stapling, clipping and deploying an automatic anastomosis device. Furthermore, the performed anastomosis procedure may include RF tissue welding, laser tissue welding, adhesive application, or other connecting methods.
  • [0066]
    Referring back to the example and FIG. 13, in one embodiment, the graft vessel 220 is secured to the target vessel 202 using the incision tensioning clip 218, as shown with reference to FIG. 13. As described earlier, the incision tensioning clip 218 includes the tines 218 a and 218 b which engage both the graft vessel 220 and the target vessel 202. Also as described earlier, the tines 218 a and 218 b are configured to rotate once the tines 218 a and 218 b penetrate the vessels 202 and 220 in order to capture the target vessel 202 and the graft vessel 220, as shown with respect to FIG. 13. Additional securing mechanisms, such as staples, clips or tissue welding may be used to secure the edges of the incision to the graft vessel to complete the anastomosis procedure. After the operation 308 is performed, the method 300 is complete.
  • [0067]
    As may be appreciated, the present invention provides a precise method for aligning a graft vessel to a target vessel in a time efficient and cost efficient manner. The incision tensioners maintain a known geometry for an incision during an anastomosis procedure. Therefore, a surgeon may precisely graft a graft vessel to a target vessel containing the incision. The present invention is preferably used with a stapling anastomosis device or anastomosis clips, such as incision tensioning clips, which obviate the need for suturing during an anastomosis procedure. Therefore, both the amount of time required to graft vessels and the attendant costs are greatly decreased. Moreover, the present invention greatly reduces the possibility of trauma to the patient due to the reduced amount of time required to graft vessels.
  • [0068]
    The above are exemplary modes of carrying out the invention and are not intended to be limiting. It will be apparent to those of ordinary skill in the art that modifications thereto can be made without departure from the spirit and scope of the invention as set forth in the following claims.
