Abstract
An orthopedic fixation system includes a sterile packaged implant kit and a sterile packaged instrument kit. The sterile packaged implant kit includes at least one surgical implant, an insertion device, and an implant package adapted to receive the at least one surgical implant and the insertion device therein. The implant package maintains the at least one surgical implant and the insertion device sterile after sterilization of the sterile packaged implant kit. The sterile packaged instrument kit includes one or more instruments necessary to use the sterile packaged implant kit and an instrument package adapted to receive the one or more instruments therein. The instrument package maintains the one or more instruments sterile after sterilization of the sterile packaged instrument kit.
Core Innovation
The orthopedic fixation system includes a first shape memory implant comprising a first leg and a second leg movable between an implanted position and an insertion position, and a first implant insertion device adapted to engage the first shape memory implant and hold the first leg and the second leg in their insertion position. A first drill guide is adapted for drilling holes into a first bone and a second bone, where the first drill guide includes a fixed separation distance substantially equal to a distance between the first leg and the second leg of the first shape memory implant in their insertion position. The system further includes a first package adapted to receive the first shape memory implant, the first implant insertion device, and the first drill guide.
In addition, the system includes a second shape memory implant comprising a first leg and a second leg movable between an implanted position and an insertion position, and a second implant insertion device adapted to engage the second shape memory implant and hold the first leg and the second leg in their insertion position. A second drill guide is adapted for drilling holes into the first bone and the second bone, where the second drill guide includes a fixed separation distance substantially equal to a distance between the first leg and the second leg of the second shape memory implant in their insertion position. A second package is adapted to receive the second shape memory implant, the second implant insertion device, and the second drill guide.
The orthopedic fixation system also includes a sizing device comprising first projections defining therebetween a first fixed distance and second projections defining therebetween a second fixed distance, with the first fixed distance different than the second fixed distance. The first fixed distance is substantially equal to the distance between the first leg and the second leg of the first shape memory implant in their insertion position, and the second fixed distance is substantially equal to the distance between the first leg and the second leg of the second shape memory implant in their insertion position. The partial content describes packaging for delivering the implant and associated drill guide and insertion device as sterile, sealable kits.
Claims Coverage
The partial content identifies three independent claims directed to an orthopedic fixation system using two shape memory implants with corresponding insertion devices and drill guides, and a sizing device with two different fixed distances. Across these claims, inventive features center on matching drill-guide fixed separation distance to implant leg separation in an insertion position, and a sizing device whose projection-defined fixed distances correspond to the respective implant leg separations.
Two shape memory implants with insertion position legs
A first shape memory implant comprising a first leg and a second leg movable between an implanted position and an insertion position, and a second shape memory implant comprising a first leg and a second leg movable between an implanted position and an insertion position.
Insertion devices holding legs in insertion position
A first implant insertion device adapted to engage the first shape memory implant and hold the first leg and the second leg in their insertion position, and a second implant insertion device adapted to engage the second shape memory implant and hold the first leg and the second leg in their insertion position.
Drill guides with fixed separation matching implant leg spacing
A first drill guide adapted for drilling holes into a first bone and a second bone, with a fixed separation distance substantially equal to the distance between the first leg and the second leg of the first shape memory implant in their insertion position, and a second drill guide adapted for drilling holes into a first bone and a second bone, with a fixed separation distance substantially equal to the distance between the first leg and the second leg of the second shape memory implant in their insertion position.
Packages receiving implant, insertion device, and drill guide
A first package adapted to receive the first shape memory implant, the first implant insertion device, and the first drill guide, and a second package adapted to receive the second shape memory implant, the second implant insertion device, and the second drill guide.
Sizing device with two different fixed distances matched to leg separation
A sizing device comprising first projections defining therebetween a first fixed distance and second projections defining therebetween a second fixed distance, wherein the first fixed distance is different than the second fixed distance, the first fixed distance is substantially equal to the distance between the first leg and the second leg of the first shape memory implant in their insertion position, and the second fixed distance is substantially equal to the distance between the first leg and the second leg of the second shape memory implant in their insertion position.
Sizing distances matched to drill-guide fixed separation distances
A sizing device comprising first projections defining therebetween a first fixed distance and second projections defining therebetween a second fixed distance, wherein the first fixed distance is different than the second fixed distance, the first fixed distance is substantially equal to the fixed separation distance of the first drill guide, and the second fixed distance is substantially equal to the fixed separation distance of the second drill guide.
Across the independent claims, the system is covered by two shape memory implants with legs movable between implanted and insertion positions, corresponding implant insertion devices holding the implant legs in the insertion position, drill guides whose fixed separation distances are substantially equal to the implant leg separation in the insertion position, packages receiving each implant set, and a sizing device with two different projection-defined fixed distances substantially equal to the respective implant leg separations.
