US Patent:

20190167443, Jun 6, 2019

Filed:

Feb 5, 2019

Appl. No.:

16/267492

Inventors:

- Kalamazoo MI, US
Joshua Stein - Hoboken NJ, US

International Classification:

A61F 2/46
A61B 17/70
A61B 17/88

Abstract:

A bone graft loading system includes a loading funnel, syringe, cannula, plunger, and loading tool. The loading funnel includes an interior passageway to receive the cannula and a syringe docking portion. The syringe may be coupled to the syringe docking portion so that it extends along a longitudinal axis that is transverse to the longitudinal axes of the cannula and the loading funnel. A user may advance bone graft from the syringe to a holding area of the loading funnel. The user may then move the loading tool through the holding area and into the interior space of the cannula to load the cannula with bone graft. This process may be repeated until the cannula is fully loaded with bone graft. The cannula and the plunger inside the cannula may then be removed from the loading funnel and coupled to an injector assembly for use in surgery.

Appl. No.:

15/360083

Inventors:

- Kalamazoo MI, US
Joshua Stein - Hoboken NJ, US

International Classification:

A61B 17/70

Abstract:

A system for percutaneous spinal fusion may include two spaced apart blades connected together by a coupling such that the blades define a percutaneous pathway from a skin incision to an implanted pedicle fastener. The coupling may be c-shaped and may have at least one flexible tab for engaging one or more holes along the length of the blades. If one of the blades becomes disconnected from the pedicle fastener, a supplemental access device may be provided comprising a tubular body having a channel therein for receiving the other of the blades. If both of the blades become disconnected, a supplemental access device may be provided comprising a gripping member received within a locking member. The gripping member may have two legs engageable with the pedicle fastener, and the locking member may move along the gripping member to prevent the legs from disengaging the pedicle fastener.
