Definitions
- the present invention relates to devices used during hole-forming in blood vessels. BACKGROUND OF THE INVENTION
- the operator measures the host vessel to determine its diameter and chooses an anastomotic connector of a corresponding size. He cuts a linear aperture along the longitudinal axis of the host vessel, exactly to the size of the connector. The operator then evaluates the incision length to ensure that it indeed has the precise length required.
- An improper host vessel size evaluation and/or aperture length can result in fatal consequences, or at least, in some cases, in the need to close up one incision and make another.
- a broad aspect of some embodiments of the invention relates to ensuring that an aperture formed in a blood vessel is of a desired length.
- a device in accordance with an exemplary embodiment of the invention assists in preventing over cutting of the aperture.
- a device in accordance with an exemplary embodiment of the invention is inserted into a blood vessel to begin an incision and may be removed while having caused only minimal damage to the vessel, which does not require stitching shut, for example, only a small puncture wound.
- An aspect of some embodiments of the invention relates to a cutter instrument that cuts an aperture in a blood vessel.
- the cutter comprises a post having a curved element with a sharp tip extending from the post, a portion of the convex aspect of the curved element comprising a sharp edge.
- the tip pierces through a host vessel wall, making an entry puncture.
- the tip makes a small cut rather than a puncture.
- the tip is optionally designed to prevent tearing and/or forming of a large aperture.
- the post is manipulated until the tip exits the blood vessel, making an exit puncture at a distance from the entry puncture while a portion of the element moves through the vessel lumen. As only the convex aspect of the cutter is sharp, no damage is caused to the blood vessel beyond these two cuts.
- the entry manipulation is assisted by the curved element being substantially an arc.
- the sharp convex edge cuts the portion between the entry and exit cuts, joining the two cuts into a single aperture.
- the cutter may be removed and/or manipulated so that a new exit puncture is made, at a correct distance.
- markings are provided on the cutter to assist in estimating the expected incision length.
- the convex edge comprises a first entry marking a first distance from the tip and a second entry marking at a second distance from the tip.
- an entry puncture into the vessel is made with the tip and the element is manipulated in the blood vessel until the entry puncture is aligned with either the first entry marking or the second entry marking.
- the post is manipulated until the tip exits the blood vessel, making an exit puncture in the vessel and the cutter is pulled away from the vessel to make an aperture joining the exit puncture with the entry puncture.
- an aperture of a first length results.
- an aperture of a second length results.
- the post and the opposing tip set the final length of the incision prior to completing the incision (when only two punctures, easily sealed, e.g., by simple pressure or a dab of adhesive, had been made). Any correction can be made by advancing the post so the opposing tip is retracted into the blood vessel and then repositioning the tip. Alternatively or additionally to setting the length, the post and tip set the exact layout of the incision (e.g., orientation).
- the use of a curved cutting edge allows focusing the cutting force on a small part of the vessel, if necessary.
- the use of a curved cutting edge simplifies the control of the position of the cutting edge, by rotating the post.
- the use of a curved cutting edge provides relative motion between the edge and the tissue being cut, as it slides on the edge, possibly assisting in cutting.
- the use of a curved cutting edge focuses the force on a relatively short section of blood vessel wall, when the post is pulled back with greater force.
- an aspect of some embodiments of the invention relates to a frame for controlling an incision length.
- the frame comprises a tip inserted into a blood vessel and a frame section that pinches a section of the blood vessel wall between the tip and the frame, thereby ensuring that cutting (e.g., with a scalpel) can be easily limited to the portion of the blood vessel pinched by the frame and/or bounded by the frame on at least one side.
- An aspect of some embodiments of the invention relates to a measurement device, optionally in the form of a slotted elongate ribbon that is used in evaluating the diameter of a host vessel and/or in evaluating an aperture length cut in the vessel.
- the ribbon comprises at least one first slot, having a first opening length, extending across a portion of the ribbon width and at least one first edge having a first dimension adapted for insertion into an aperture in a blood vessel.
- the at least one first slot is placed around the blood vessel to evaluate whether the vessel is, for example, smaller than the minimal size that can receive an anastomotic connector.
- an aperture length of an appropriate length for the anastomotic connector, is cut into the host vessel using, for example, the cutter described herein.
- the at least one first edge of the elongate ribbon is placed in or near the aperture to determine that the aperture has an appropriate length for the connector.
- the ribbon comprises multiple slots having different opening dimensions and the vessel is evaluated for reception of two or more anastomotic connectors, each having a different diameter.
- the ribbon comprises multiple edges having multiple lengths that are adapted to measure two or more aperture lengths in the host vessel.
- the measurement device includes a marker for indicating a desired incision length and/or position.
- the measurement device includes, at one or both of the incision measurement edges, a sponge (or a tissue adhesive) with ink.
- the measurement device includes a surface suitable for absorbing or accepting ink from a marker and then exuding said ink when in contact with tissue.
- the marker may be used to indicate a desired incision length prior to cutting, instead of or before testing the incision by inserting the measurement device.
- the ink marks the blood vessel when the marker is inserted into the incision, thereby marldng alongside the incision the actual length of the marker.
- a cap is optionally provided to protect the marker section of the measurement device, before use.
- a kit suitable for use during anastomotic surgical procedures comprises at least one blood vessel cutter and at least one blood vessel evaluator.

- Fig. 1 is an isometric view of a vessel evaluator 200, used in evaluating the diameter of blood vessel 810, (Fig. 3B) in accordance with an exemplary embodiment of the invention.
- Evaluator 200 comprises notches 210, 220 and 230 that are used to measure the diameter of blood vessel 810 and determine whether a larger or smaller aperture and corresponding anastomotic connector is appropriate.
- notch 220 having a diameter, for example of 3.5 millimeters, is placed around the blood vessel. If the vessel 810 diameter fits into notch 220, smaller notch 210 is placed around vessel 810. If vessel 810 is larger than smaller notch 210, vessel 810 has a diameter of between 2.0 and 3.5 millimeters, appropriate for an aperture and connector, for example, of 2.5 millimeters.
- vessel 810 does not fit into notch 220, larger notch 230 is placed around vessel 810. If vessel 810 fits into larger notch 230, it has a diameter between 3.5 and 6.0 millimeters and appropriate for an aperture and connector, for example of 2.9 millimeters.
- an anastomosis kit may be provided with only two (or other small number, such as three or four) sizes of connectors, small and large. Size small, uses vessels between the sizes of notches 210 and 220 and size large uses vessels between the sizes of notches 220 and 230. An incision evaluator described below may also be calibrated for these two sizes.
- Blood Vessel Cutter Fig. 2 is a side view of a blood vessel cutter 300 having an overall "J" shape that is appropriate for cutting an incision along a longitudinal axis of vessel 810 (Fig. 3D), in accordance with an exemplary embodiment of the invention.
- Cutter 300 comprises a post 346 from which a curved blade 302 with a sharp tip 306 project.
- a portion of curved blade 302 comprises a diameter formed around an origin 380 and a sharp convex edge 376. While a perfect arc is not required, for example a piece-wise section or a non-arc curve may be used, an arc section may have the advantage of easy manipulation as described below.
- Figs. 3A-3D demonstrate operation of cutter 300.
- Tip 306 is pressed against a surface of blood vessel 810 to make entry cut 340.
- the cut is actually a small puncture, possibly with no tearing beyond a pinprick.
- Blade 302 is rotated and/or manipulated, generally in a direction 310. In an exemplary embodiment of the invention, this rotation is assisted by blade 302 being arcuate and not having a cutting edge on its outer curve, as in some embodiments of the invention.
- Fig. 3C shows tip 306 making an exit cut (or hole) 330.
- an exit marking 334 near tip 306 is provided which can be visualized by the operator.
- Marking 334 allows the surgeon to determine that tip 306 has fully pierced blood vessel 810 and/or that cutter 300 will not displace inappropriately during cutting.
- cutter 300 is then pulled in a direction 312 so that sharp edge 376 cuts the distance between entry cut 340 and exit cut 330.
- a surgical kit is provided with a first cutter 300 having a first diameter, appropriate for creating an aperture of a first size and a second cutter 300 having a diameter appropriate for creating an aperture of a second size.
- a single cutter 300 is provided that can be used to create at least two apertures of different sizes.
- cutter 300 comprises exit marking 334, a first entry marking 342 a first distance 384 from marking 334 and a second entry marking 344 a second distance 386 from marking 334.
- blade 302 is manipulated, for example, so that a first entry marking 342 is aligned with entry cut 340.
- the operator manipulates tip 306 so it exits vessel 810, making exit cut 330 that he aligns with exit marking 334.
- aperture 222 of first length 384 for example 2.5 millimeters, is formed.
- exit marking 344 is aligned with exit cut 340 and entry cut 330 is aligned with entry marking 344.
- an aperture having a second length 386 results.
- a physician may intentionally stretch or compress the blood vessel, for example during manipulation (Fig. 3B), resulting a differently sized incision.
- a cutter with a suitably changed marking and/or geometry is provided.
- a radius 386 of the curve of blade 302 is, for example 2.9 millimeters, it could be as small as 2.6 millimeters for smaller host vessels and anastomotic connectors and as large as 3.9 millimeters for larger vessels and larger anastomotic connectors. While distance 384, including two widths of blade 302, is 2.0 millimeters, it could be as small as 1.4 millimeters, or less, such as 1.2 millimeters for smaller host vessels and anastomotic connectors and as large as 2.9 millimeters for larger vessels and larger anastomotic connectors.
- the thickness of blade 302 is, for example 0.4 mm and the blade may be smooth or serrated.
- tip 306 is rounded and needle like, so that it will not cause tears. Rounding can be achieved, for example, using electro-polishing.
- a section of non-cutting area, for example 0.5 mm, 1 mm or 2 mm is optionally provided between the tip and the cutting area, to prevent inadvertent cutting when tip 306 exits for the vessel wall.
- evaluator 200 (Fig.l) comprises a first end edge 212 having a first measurement 213 of 2.5 millimeters and a second end edge 222 having a second measurement 223 of 2.9 millimeters.
- end 212 is placed into aperture 222 and a snug fit indicates that aperture 222 is 2.25 millimeters (size "small”). For an aperture of 3 millimeters (size "large”), end 212 is placed into aperture 222 and a snug fit indicates that aperture 222 is of an appropriate length.
- end 212 is placed into aperture 222 and a snug fit indicates that aperture 222 is of an appropriate length.
- aperture 222 is shorter than necessary, it must be lengthened. If aperture 222 is longer than necessary, it must be closed to forgo, for example, anastomotic connection at this site.
- handle 240 has a length 292 of 9 centimeters and a width 260 of 6.0 millimeters.
- handle 240 could have a length of between 6 and 12 centimeters and width 260 of 4-8 millimeters depending on the vessel being evaluated and/or whether the procedure entails a fully exposed surgical field or a closed surgical field accessed, for example, through a small incision. Additionally, large or smaller lengths are contemplated based upon, for example, the procedure location and the access technique.
- a first end 212 and a second end 222 have a projection distance 242 of 1.5 centimeters and offsets 216 and 214 of 2.0 millimeters each. Again, depending upon the size of the vessel being evaluated and/or whether the surgical field is open or closed, these measurements may be varied up or down.
- Notches 210, 220 and 230 have, for example, a "u" shape, appropriate for receiving blood vessel 810.
- evaluator 200 and/or cutter 300 comprise materials that are compatible with biologic tissue, for example titanium. Alternatively or additionally all edges are smoothed to prevent trauma to tissue associated with sharp edges. Marking evaluator
- FIG. 5 is a schematic illustration of a marking end 501 of a marking evaluation gauge 500, in accordance with an exemplary embodiment of the invention.
- a marking area 504 is adapted to apply ink to a wall of vessel 810 (e.g., Fig. 4).
- marking area 504 is used as a contact stamp to mark the prospective incision with ink.
- a marker is used to apply ink to a suitably treated section of gauge 500, so that it will later release the ink.
- area 504 is a sponge or adhesive, or is rough, and ink is applied, for example with an ink pad or by running a marker on it.
- area 504 For some markers and/or ink types, no special preparation of area 504 is required. In another embodiment, area 504 already contains the ink and is optionally protected before use by a cap 508. While a solid marking area is shown, in some embodiments, a different pattern is useful, for example, a set of ruled lines.
- area 505 is a marker area, forming a front edge 502 of end 501 and/or on one side thereof. Optionally, area 505 is V shaped, with its apex pointed towards edge 502.
- end 501 is inserted into a formed incision and marking area 504 indicates on the outside of the vessel, the width of end 501, for easier comparison.
- marking area 504 indicates on the outside of the vessel, the width of end 501, for easier comparison.
- the forward surface of end 501 is flat edge 502, with sharp corners 506 such that it has a rectangular shape. Alternatively, corners 506 are rounded. Alternatively or additionally, edge 502 is V shaped.
- Cutting Frame Figs. 6A and 6B illustrate a cutting frame 600, used for controlling a length of incision in a target vessel 620, in accordance with an exemplary embodiment of the invention.
- Frame 600 comprises a penetration section 602 which is inserted into blood vessel 620, forming a puncture therein and having a puncture lip 622.

- cutting frame 600 includes a frame 608 which can be arranged in a desired manner with respect to penetration section 602, as will be described with reference to Fig. 6B.
- frame 608 is attached to penetration section 608 using a hinge 614.
- a back section 618 of frame 608 is optionally closed to limit rotation of frame 608 in one direction.
- cutting frame 600 provides one or both of the following functions: (a) a forward section 612 serves as a stop for a cutting instrument cutting along slot 606; and (b) frame side sections 610, which optionally couple forward section 612 to hinge 608 lock a section of vessel 620, by pinching it between at least a portion of one or both of sides 610 and shaft 616, adjacent penetration tip 602, so that the locked section does not change and the cutting is exact.
- one or more markings 619 are provided adjacent slot 606, so that the final length of an incision can be estimated before cutting is started.
- an end of the slot serves as a marking for insertion depth of the penetration tip into the blood vessel, optionally, different length slots are provided for different desired lengths. Then, in use, a knife can be inserted in the middle of the slot and used to cut both ways, towards the end of the slot and towards the penetration tip.
- frame 608 can be released from penetration section 602 and penetration section 602 advanced into or retracted from vessel 620, as needed, and then frame 608 locked again to penetration section 602, to prevent inadvertent changes in the incision configuration.
