Filed:

Mar 13, 1998

Appl. No.:

9/042270

Inventors:

John J. Jancsek - Blaine MN
Creighton R. Thompson - Chaska MN
Robert G. Lau - Anoka MN
Todd J. Mickley - Andover MN
Erik E. Emstad - Lauderdale MN

Assignee:

Hoffman Enclosures, Inc. - Anoka MN

International Classification:

A47B 4700

US Classification:

3122654

Abstract:

An electrical enclosure includes a frame and a seismic subframe. The seismic subframe includes vertical frame members interconnecting with braces at the top and bottom and opening at the front and rear of the enclosure. The assembly mounts to the rectangular frame of the enclosure. Grid straps extend from front to rear to connect the assemblies and provide additional bracing. Front and rear panels include gusset type braces at the corners mounted to the panels that engage inner edges of the framework to provide positioning as well as support.

Inventors:

- Austin TX, US
Erik Earl Emstad - Austin TX, US

International Classification:

A61F 2/44

Abstract:

An intervertebral spacing implant, including: a seat having an interior surface and an exterior surface; branches having an anterior end and a posterior end, the anterior end of the branches coupled to the seat and extending in a direction away from the seat, each of the branches having an interior surface and an exterior surface opposite the interior surface, the seat and the branches forming a cage, the exterior surface of the seat and the exterior surface of the branches defining an internal volume of the cage, the cage including fenestrations; a spacer configured to fit within the cage and move in the direction away from the seat and toward the posterior end of the plurality of branches, the spacer and the cage configured such that the branches will move from an unexpanded position to an expanded position when the spacer is urged in the direction away from the seat.

- Austin TX, US
Erik Emstad - Austin TX, US

International Classification:

A61F 2/44
A61F 2/30
A61F 2/46

Abstract:

An embodiment includes an expandable intervertebral body fusion device with two expansion wedges within a generally hollow main body. After implantation into the intervertebral disc space, the expansion wedges are simultaneously moved from the center of the device toward the ends, which flexes the arms of the cage and increases the size of the implant. This expansion stabilizes the device in the disc space and increases the disc height, thereby reducing foraminal compression of spinal nerves and creating a stable motion segment for eventual fusion. Other embodiments are described herein.

International Classification:

A61B 10/02
A61B 10/00

Abstract:

An embodiment includes a system comprising: a lower piston in a lower chamber and an upper piston in an upper chamber; a filter between the lower and upper pistons; at least one processor and memory to: move the lower piston away from the filter, while the upper piston is still, to draw bone marrow aspirate (BMA) into the lower chamber from an external container; move the lower piston towards the filter while simultaneously moving the upper piston away from the filter to advance BMA fluid of the BMA from the lower chamber across the filter and into the upper chamber and to locate BMA cells of the BMA adjacent the filter and within the lower chamber; move the lower piston toward the filter, while the upper piston is still, to advance the BMA cells out of the lower chamber and into one of the external container and another external container.
