Abstract

Embodiments include a system that facilitates placement of a rod through receiving portions of screws placed along the spine. The system includes a rod and a cable detachably connectable to the rod to pull the rod through the receiving portions of the screws. Some embodiments include methods and devices for inserting a rod into a plurality of screws and for ex situ templating of a rod. These can include connecting a cable to a rod, inserting the cable through the plurality of screws, and using the cable to pull the rod into position. The methods of ex situ templating of the rod can include contacting a templating member to each of the screws so that a portion of the templating members replicate the relative positioning of the screws and shaping a rod to match the relative positioning of the portion of the templating members.

Claims

1-4. -4. (canceled)

5. (canceled)

6-23. -23. (canceled)

24. A method of delivering a rod to a plurality of spinal screws, comprising:

advancing a penetrating member and cable through heads of each of a plurality spinal screws implanted into a plurality of adjacent vertebrae;

pulling the penetrating member and cable to advance a rod detachably connected to the cable through the heads of each of the screws, wherein the rod is detachably connected to a first end of the cable and the penetrating member is integral with or connectable with a second end of the cable; and

selectively engaging the penetrating member with one or more pass members to direct the penetrating member between adjacent spinal screws.

25. The method of claim 24, wherein a single portion of the cable is advanced into a patient through, along or at an angle to a first tower extending from a first spinal screw, through the heads of each of the spinal screws, and out of the patient through, along or at an angle to a second tower extending from a second spinal screw.

26. The method of claim 24, wherein the direction of the advance of the rod through the heads of the spinal screws is the same as the direction of the advance of the cable through the heads of the spinal screws.

50. The method of claim 24, further comprising a rod puller configured to engage the cable and facilitate pulling of the rod into position within the receiving portions of the screws.

51. The method of claim 24, further comprising a delivery tube having a curved delivery portion configured to direct delivery of the penetrating member into a receiving portion of a screw

52. The method of claim 24, further comprising a hook or deflecting member configured to be advanced into one or more of the extension sleeves to facilitate the advance of the penetrating member

53. The method of claim 24, further comprising a penetrating member removal device configured to redirect a penetrating member such that further advancement of the penetrating member moves the penetrating member out of the patient'"'"'s body.

54. The method of claim 24, wherein the cable comprises a plurality of regularly spaced markers.

27. (canceled)

28-49. -49. (canceled)

55. A method of delivering a rod to a plurality of spinal screws, comprising:

advancing a penetrating member and cable through heads of each of a plurality of spinal screws, wherein each spinal screw comprises a threaded shaft and a head having a receiving portion;

pulling the penetrating member and cable to advance a rod sized and shaped to be inserted into the receiving portions of the spinal screws, wherein the rod includes a first end detachably connected to a first end of the cable and the penetrating member is integral with or connectable with a second end of the cable;

selectively engaging the penetrating member with one or more pass members, wherein one or more pass members are configured to advance the penetrating member from a receiving portion of a first pedicle screw to a receiving portion of a second pedicle screw.

56. The method of claim 55, further comprising a rod puller configured to engage the cable and facilitate pulling of the rod into position within the receiving portions of the screws.

57. The method of claim 55, further comprising a delivery tube having a curved delivery portion configured to direct delivery of the penetrating member into a receiving portion of a screw

58. The method of claim 55, further comprising a hook or deflecting member configured to be advanced into one or more of the extension sleeves to facilitate the advance of the penetrating member

59. The method of claim 55, further comprising a penetrating member removal device configured to redirect a penetrating member such that further advancement of the penetrating member moves the penetrating member out of the patient'"'"'s body.

60. A method of delivering a rod to a plurality of spinal screws, comprising:

advancing a penetrating member and cable through a cannula configured to facilitate insertion of a rod through the receiving portions of a plurality spinal screws implanted into a plurality of adjacent vertebrae;

pulling the penetrating member and cable to advance the rod detachably connected to the cable through heads of each of the plurality spinal screws, wherein the rod is sized and shaped to be inserted into the receiving portions of the spinal screws and wherein the rod is detachably connected to a first end of the cable and the penetrating member is integral with or connectable with a second end of the cable; and

selectively engaging the penetrating member with one or more pass members to direct the penetrating member between adjacent spinal screws.

61. The method of claim 60, wherein the cannula is angularly positioned relative to the head of the screw

62. The method of claim 60, further comprising a rod puller configured to engage the cable and facilitate pulling of the rod into position within the receiving portions of the screws.

63. The method of claim 60, further comprising a delivery tube having a curved delivery portion configured to direct delivery of the penetrating member into a receiving portion of a screw

64. The method of claim 60, further comprising a hook or deflecting member configured to be advanced into one or more of the extension sleeves to facilitate the advance of the penetrating member

65. The method of claim 60, further comprising a penetrating member removal device configured to redirect a penetrating member such that further advancement of the penetrating member moves the penetrating member out of the patient'"'"'s body.

66. The method of claim 60, wherein the cable comprises a plurality of regularly spaced markers.
