The housing 504 houses a needle cartridge 540. The needle cartridge 540 includes a plurality of needle slots 544 in which needles 546 are disposed. The needle slots 544 are preferably arranged parallel to each other and extend from a distal end to a proximal end of the needle cartridge 540. In the embodiment shown in FIG. 1, the needle cartridge 540 has three needle slots 544. The needle cartridge 540 is moveable within the housing 504 between at least a first and a second position. In one embodiment, the housing 504 includes a spring element 542, such as a leaf spring or other suitable spring element, that contacts the needle cartridge 540 so as to move the needle cartridge 540 within the housing 504 between at least the first and second positions. In the embodiment shown in FIG. 1, the spring element 542 contacts the needle cartridge 540 so as to move the needle cartridge 540 within the housing 504 between three positions. In a first position, the needle cartridge 540 is positioned such that a first needle slot 544 a is aligned with the central axis 532 a of the needle pusher channel 532 and with the central axis 510 a of the needle insertion lumen 510 of the proximal part 502. In a second position, as shown in FIG. 1, the needle cartridge 540 is positioned such that a second needle slot 544 b is aligned with the central axis 532 a of the needle pusher channel 532 and with the central axis 510 a of the needle insertion lumen 510 of the proximal part 502. In a third position, the needle cartridge 540 is positioned such that a third needle slot 544 c is aligned with the central axis 532 a of the needle pusher channel 532 and with the central axis 510 a of the needle insertion lumen 510 of the proximal part 502.
In one embodiment, the distal lumen 507 contains a valve 550 to prevent blood from flowing through the distal lumen 507 during insertion of the device into the puncture. Without a valve to prevent the flow of blood through the distal lumen 507 blood may escape through the distal lumen 507 while the device is being inserted into a blood vessel. Such excess blood could cause an undesirable condition such as hematoma. In the preferred embodiment, the valve 550 should be positioned in a distal end of the distal lumen 507 so as to not inhibit the ability of the distal lumen 507 to receive suturing needles 546.
FIGS. 13 a and 13 b show a suture device 1500 according to another embodiment of the present invention. The suture device 1500 includes a tube 1501 having a substantially circular cross-section. The suture device 1500 includes a distal part 1508 that defines a distal lumen 1507 having a central axis 1507 a, a proximal part 1502 that defines a needle insertion lumen 1510 having a central axis 1510 a, and a housing 1504 attached to a proximal end of the proximal part 1502. A suture removal slot 1513 extends along the surface of the proximal part 1502 and communicates with the needle insertion lumen 1510 so as to open an interior of the needle insertion lumen 1510 to the outside of the device 1500 along an entire length of the needle insertion lumen 1510. As described more fully above in connection with the suture removal slot 513 of the suture device 500 shown in FIG. 1, a width of the suture removal slot 1513 is less than a diameter of a needle inserted through the needle insertion lumen 1510 so that a needle received in the needle insertion lumen 1510 can not escape from the needle insertion lumen 1510 via the suture removal slot 1513.
The housing 1504 houses a needle cartridge 1540. The needle cartridge 1540 includes a needle slot 1544 in which needles 1546 are disposed. FIG. 13 b illustrates a cross-sectional view of the needle cartridge 1540. The needle slot 1544 extends from a distal end to a proximal end of the needle cartridge 1540. In the embodiment shown in FIGS. 13 a and 13 b, the needle slot 1544 is arranged vertically. However, according to various other embodiments of the present invention, the needle slot 1544 is not arranged vertically. Furthermore, the needle slot 1544 is shown having fives needles, e.g., the needles 1546 a to 1546 e, disposed therewithin. However, the present invention contemplates that the needle slot 1544 may be configured to include any number of needles 1546. The needles 1546 are moveable within the needle slot 1544 such that the needles are successively positioned in alignment with the needle pusher channel 1532 and the needle insertion lumen 1510. In one embodiment, the housing 1504 includes a spring element 1542, such as a leaf spring or other suitable spring element, that contacts at least one of the needles 1546 so as to move the needles 1546 within the needle slot 1544. For instance, as shown in FIG. 13 b, in one embodiment of the present invention, the spring element 1542 contacts lower needle 1546 e so as to bias all of the needles 1546 within the needle slot 1544 upwards, such that the uppermost needle 1546 a is aligned with the needle pusher channel 1532 and the needle insertion lumen 1510. Once the uppermost needle 1546 a is employed, e.g., pushed out of the needle slot 1544 during operation of the device, the spring element 1542 biases the remaining needles 1546 upwards so that the second uppermost needle, e.g., needle 1546 b, is automatically aligned with the needle pusher channel 1532 and the needle insertion lumen 1510.
It should be recognized that, while the operation described above illustrates the operation of the suture device 500 shown in FIGS. 1 and 2, a similar operation may be performed when the suture device 1500 shown in FIGS. 13 a and 13 b is employed. For instance, when the suture device 1500 shown in FIGS. 13 a and 13 b is employed, the suture device 1500 is placed in a first suture position within a puncture, e.g., positioned to insert a needle through a first side of a puncture. Advantageously, the needle slot 1544 of the needle cartridge 1540 has two or more needles 1546 disposed, e.g., pre-loaded, within the needle slot 1544. In the first position, the uppermost needle 1546 in the needle slot 1544, e.g., needle 1546 a, is aligned with the central axis 1532 a of the needle pusher channel 1532 and with the central axis 1510 a of the needle insertion lumen 1510 of the proximal part 1502. A first needle 1546 a has a suture 1528 attached at its proximal end. The needle pusher 1534 is moved distally within the needle pusher channel 1532 so as to push the first needle 1546 a out of the needle slot 1544 and through the needle insertion lumen 1510 of the proximal part 1502. The pointed distal end of the first needle 1546 a exits the needle insertion lumen 1510 and penetrates the lining of the blood vessel on a first side of the puncture. The first needle 1546 a is then advanced through the needle receiving opening 1522 until the entire first needle 1546 a is inserted within the distal lumen 1507. The needle pusher 1530 is then withdrawn back to its original, e.g., proximal-most, position in the needle pusher channel 1532.
FIGS. 14 to 16 illustrate another process for sealing a puncture in accordance with the present invention, which may be employed with either the suture device 500 shown in FIGS. 1 and 2 or the suture device 1500 shown in FIGS. 13 a and 13 b. For the purposes of illustration only, the process will be described in connection with the operation of the suture device 500 shown in FIGS. 1 and 2. As shown in FIG. 14, the suture device 500 is placed in a first suture position within a puncture, and the needle pusher 534 is moved distally within the needle pusher channel 532 so as to push the first needle 546 a such that the pointed distal end of the first needle 546 a penetrates the lining of the blood vessel on a first side of the puncture. The first needle 546 a is then advanced until the first needle 546 a is inserted within the distal lumen 507, and the needle pusher 530 is withdrawn back to its original, e.g., proximal-most, position in the needle pusher channel 1532. The first needle 546 a has a suture 528 attached at its proximal end. In this embodiment, the suture 528 has attached thereto a patch 560 of hemostatic agent. In one embodiment of the present invention, the hemostatic agent includes collagen and may have a sponge or compressed sponge form-however, the present invention contemplates that any type of hemostatic agent in any shape or form may be employed. In the embodiment shown, the hemostatic agent patch 560 has a first hole 560 a and a second hole 560 b through which the suture 528 is inserted, thereby attaching the hemostatic agent patch 560 to the suture 528. Various other attachment methods may alternatively be employed.
