Benefits of technology

The patent describes a surgical device that can be used to create small incisions in patient tissue. It is designed to be partially inserted into the patient and then inflated to create a larger space in the tissue. This makes it easier to perform minimally invasive surgeries.

Problems solved by technology

Currently, one of the most difficult portions of the human to repair and to protect during healing is the spinal column or spine.
Should one or more discs be damaged, a person may experience pain from a number of the modes.
In one mode, the annulus may be damaged so that the disc bulges and presses on the spinal nerve.
In another mode, the annulus may fail to provide sufficient support so that the portion of the spine in a superior position to the damaged annulus compress downwardly, which also compresses the spinal nerve.
Another mode is a damaged vertebra that results in pain or contributes to damage of portions of the spine.
While there are non-surgical treatments available for some pain originating from damage to the spinal column, such are typically limited to minor irregularities.
There are a number of difficulties with current designs and procedures for locating and implanting the variety of intervertebral implants.
This method and design puts a significant amount of stress on the implant itself, as it is the implant that is doing much of the work.
Such compression may damage the implant before the implant is ever disposed in the intervertebral space, and high frictional forces are exerted on the sides of the implant that are in contact with the arms.
Finally, as the implant is doing the work, manipulation of the implant to a desired purpose is hindered, particularly once the implant has passed beyond the arm distal portions so that it is in full and direct contact with the endplates.
Additionally, the implant must be located between the arms at the distal end of the distractor / implantor device prior to placing the device in situ, resulting in the spikes being exposed and seating of the implant being susceptible to being effected during the preliminary steps of interfacing the distractor device with the vertebrae.
For instance, none of the devices permits selection of an implant device after distraction has occurred.
The above-discussed devices do not permit such inspection without sequential insertion and removal of the distractor / implantor device, or another device (such as a sizer or spacer).
Similarly, none of the devices discussed herein allows for sequentially implanting a plurality of implant constructs, or components thereof.

Embodiment Construction

[0119]Referring initially to FIG. 1, a surgical device 10 is illustrated for distraction of adjacent vertebrae and implantation of artificial intervertebral implants. The surgical device 10 may be described as both a distractor and as an implantor; for convenience herein, the surgical device 10 is referred to as an IDD 10. In use, a leading or operative end 12 of the IDD 10 is initially inserted between adjacent vertebrae in a first orientation, the IDD 10 then being rotated to a second orientation to fully distract the vertebrae for receiving an implant therebetween. One or more implants are loaded into a central cannula 14 of the IDD 10 and then forced advanced through the cannula 14, out from the operative end 12, and into the intervertebral space.

[0120]In greater detail, a form of the IDD 10 includes an elongated insertion and distraction portion referred to herein as a barrel 20 having the operative end 12 distally located from a stock end 22. The barrel 20 includes a loading c...

Abstract

Various surgical devices and methods for facilitating distraction of adjacent vertebrae and / or insertion of an intervertebral implant material therebetween are disclosed. The devices include an elongated barrel having a cannula. Implant materials may be inserted through the cannula. The barrel is expandable to distract the adjacent vertebrae. In one embodiment, the barrel includes a first section and a second section. In one embodiment, an inner member is reciprocally positioned within the barrel. Advancement of the inner member within the cannula causes distraction of the barrel.

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of U.S. patent application Ser. No. 14 / 286,639, filed May 23, 2014, which is a continuation-in-part of U.S. patent application Ser. No. 12 / 434,328, filed May 1, 2009, which issued as U.S. Pat. No. 8,734,515 on May 27, 2014 and which in turn claims priority to provisional Application No. 61 / 051,036, filed on May 7, 2008, and all of which are incorporated by reference herein in their entireties.FIELD OF THE INVENTION[0002]The invention relates to surgical implants, and more particularly to devices for distracting two or more anatomical features and / or inserting an implant material, and to methods related thereto.BACKGROUND OF THE INVENTION[0003]Currently, one of the most difficult portions of the human to repair and to protect during healing is the spinal column or spine. In simple terms, the spine may be viewed as a series of vertebrae connected by and alternating with interstitial positioned spinal discs...
