Patent number: 7976464Abstract: A device for retracting tissue provides access to a spinal location within a patient. The device includes an elongate body and a passage. The elongate body has a proximal portion and a distal portion. The elongate body defines a length between the proximal and distal portions along a longitudinal axis such that the distal portion can be positioned inside the patient adjacent the spinal location while the proximal portion is accessible. A transverse cross-section of the elongate body in the proximal portion has a first dimension that is longer than a second dimension. The first dimension is perpendicular to the second dimension. The passage extends through the elongate body between the proximal and distal portions. The elongate body is configured such that the proximal portion may be tilted with respect to the distal portion in a first direction generally aligned with the first dimension and in a second direction generally aligned with the second dimension.Type: GrantFiled: August 26, 2004Date of Patent: July 12, 2011Assignee: Zimmer Spine, Inc.Inventors: Alan E. Shluzas, Karl Dallas Kirk, III, Walter Stoeckmann

Patent number: 7691120Abstract: A device for provides access to a surgical location within a patient. The device has an elongate body that has a proximal portion, a distal portion, a first slot segment, and a second slot segment that is angled relative to said first slot segment. The elongate body defines a passage for accessing the surgical location with surgical instruments. The elongate body has a contracted configuration for insertion into the patient and an expanded configuration for providing access to the surgical location. The cross-sectional area of the passage at a first location of the elongate body is greater than the cross-sectional area of said passage at a second location of the elongate body. A movable tab is configured to extend into the second slot segment when the elongate body is in the expanded configuration to retain the elongate body in the expanded configuration.Type: GrantFiled: August 26, 2004Date of Patent: April 6, 2010Assignee: Zimmer Spine, Inc.Inventors: Alan E. Shluzas, Gene P. DiPoto, Gary L. Lowery, Karl Dallas Kirk, III, Walter Stoeckmann, Donald Van Royen

Patent number: 7179225Abstract: A retractor has an elongate body and an expandable shroud. The elongate body has an outer surface and an inner surface partially defining a passage. The elongate body also has a first longitudinal edge and a second longitudinal edge. The elongate body is capable of having an enlarged configuration when inserted within the patient. In the enlarged configuration the first longitudinal edge is spaced apart from the second longitudinal edge. The expandable shroud is configured to extend from the first longitudinal edge to the second longitudinal edge when the first and second edges are spaced apart. The shroud partially defines the passage. The cross-sectional area of said passage at a first location is greater than the cross-sectional area of the passage at a second location, wherein the first location is distal to the second location.Type: GrantFiled: August 26, 2004Date of Patent: February 20, 2007Inventors: Alan E. Shluzas, Karl Dallas Kirk, III, Walter Stoeckmann, Gene P. DiPoto

Patent number: 6226886Abstract: A tape measure having a housing that encloses a coiled tape rule retractably mounted therein. The housing is constructed with an outer coating of a generally soft, resilient, pliant material that extends over a substantial portion of the housing. The tape measure further provides a locking button that is slidably attached to the housing and is adapted to selectively prevent the tape rule from moving with respect to the opening in the housing. The locking button generally includes a central portion that is located adjacent to the peripheral wall and at least one side portion located adjacent to a side wall of the housing. The locking button further includes an outer surface with an outer coating thereon of a relatively soft, skid-resistant material. The tape measure further provides a tape clip attached to a terminal end of the tape rule that includes a friction member made of a generally soft, non-skid material attached to a clip portion of the tape clip.Type: GrantFiled: May 6, 1999Date of Patent: May 8, 2001Assignee: General Housewares CorporationInventors: Donald R. Lamond, Bert D. Heinzelman, Dylan Akinrele, Walter Stoeckmann, Richard Whitehall

Patent number: 5921967Abstract: The present invention is directed toward a plunger provided for use in a nozzle assembly. The nozzle assembly includes an internal chamber with an outwardly tapered portion at one end thereof. The plunger includes a plurality of outwardly curved prongs or legs which mate with an inwardly tapered portion of the internal chamber in order to allow the piston of the injector to be released from the plunger. As a result, the plunger may be removed from the injector when the nozzle assembly is removed therefrom. This plunger may include a frangible portion so that, upon firing, a first driving member of the plunger breaks away from a second driving member of the plunger. As a result of this frangible connection, the first driving member remains lodged in a distal portion of the chamber to prevent reuse of the nozzle assembly.Type: GrantFiled: December 24, 1996Date of Patent: July 13, 1999Assignee: Medi-Ject CorporationInventors: Peter L. Sadowski, David Schiff, Walter Stoeckmann, Paul Mulhauser

Patent number: 5875976Abstract: The present invention is directed toward a locking mechanism for aiding in the prevention of accidental or unintentional disengagement of the nozzle assembly from a needleless injection device. In one embodiment of the locking mechanism, a stud positioned on the nozzle assembly engages a recess in the injector to help to deter the nozzle assembly from rotating during firing of the injector. In another embodiment of the locking mechanism, a nib on the nozzle assembly engages a recess in the injector to deter the nozzle assembly from rotating during firing of the injector. A retaining element may be utilized within the injector to provide the recesses for engagement with the locking mechanisms.Type: GrantFiled: December 24, 1996Date of Patent: March 2, 1999Assignee: Medi-Ject CorporationInventors: Sheldon Nelson, David Schiff, Walter Stoeckmann

Patent number: 5769138Abstract: An injector nozzle which has a body defining a chamber. A portion of the body has an orifice which communicates with the chamber for allowing fluid to enter into or exit from the chamber. The nozzle body includes at least one depression which is configured and dimensioned to cooperatively engage a tab member of an associated component for coupling thereto. The depression is also configured and dimensioned to positively lock the body to the associated component. The body portion which contains the depression is spaced proximally from the orifice. Also, an adapter for coupling the nozzle to a fluid container. The adapter includes a tubular member having first and second ends and a wall therebetween. The wall includes a passageway therethrough with the first end being dimensioned and configured to cooperatively engage the nozzle. The orifice of the nozzle generally aligns with the wall passageway for fluid communication therebetween.Type: GrantFiled: April 1, 1996Date of Patent: June 23, 1998Assignee: Medi-Ject CorporationInventors: Peter L. Sadowski, Sheldon Nelson, David Schiff, Walter Stoeckmann
