US Patent:

6916330, Jul 12, 2005

Filed:

Oct 30, 2001

Appl. No.:

10/024221

Inventors:

Robert E. Simonson - Boca Raton FL, US

Assignee:

DePuy Spine, Inc. - Raynham MA

International Classification:

A61M029/00

US Classification:

606191

Abstract:

A non-cannulated dilator that is designed with a rigid elongated solid body and with a judiciously configured tip is utilized as the first dilator of a series of dilators which are inserted into the body of a patient for minimally invasive spinal surgery and is made from a solid elongated body, that could be round, ovoid or other cross sectional configuration whose diameter is greater than one and a half (1) millimeter, and that includes a tool engaging end portion at the proximal end is sufficiently rigid so as not to bend and has a pointed shaped insertion end portion at the distal end with the point of the pointed end being discreetly blunted and utilized in a surgical procedure as a replacement of the typical guide wire and is characterized as providing a “feel” to the surgeon as it penetrates through the tissue and muscle of the patient as it proceeds toward the target.

Appl. No.:

10/021809

Inventors:

Robert E. Simonson - Boca Raton FL, US

Assignee:

DePuy Spine, Inc. - Raynham MA

International Classification:

A61F 5/00
A61F 17/58

US Classification:

606 86, 606 99

Abstract:

A dilator retractor and the dilators that are used for minimally invasive spinal surgery or other surgery are configured to accommodate the anatomical structure of the patient as by configuring the cross sectional area in an elliptical shape, or by forming a funnel configuration with the wider end at the proximate end. In some embodiments the distal end is contoured to also accommodate the anatomical structure of the patient so that a cylindrically shaped, funnel shaped, ovoid shaped dilator retractor can be sloped or tunneled to accommodate the bone structure of the patient or provide access for implants. The dilator retractor is made with different lengths to accommodate the depth of the cavity formed by the dilators.

Assignee:

DepuY Spine, Inc. - Raynham MA

International Classification:

A61B 17/58

US Classification:

606 86A, 606190, 600203

Abstract:

A minimally invasive surgical method includes inserting a first port that defines a first pathway to a first vertebra, advancing a first anchor through the first port to the first vertebra, inserting a second port that defines a second pathway to a second vertebra, advancing a second anchor through the second port to the second vertebra, positioning a first end of a fixation element in the first port, and advancing the first end of the fixation element subcutaneously through an opening in the first port and an opening in second port to the second anchor. A surgical access port includes a proximal end, a distal end, and a sidewall defining a lumen extending from the proximal end to the distal end. The port may include a first opening formed in the sidewall that defines a passageway for medical hardware from the lumen to external to the port.

Appl. No.:

10/165991

Inventors:

Robert E. Simonson - Boca Raton FL, US

Assignee:

DePuy Spine, Inc. - Raynham MA

International Classification:

A61M 5/00

US Classification:

604117, 60416401, 604500, 606108

Abstract:

A relatively inexpensive cannula is sized by including indica on a cannulated dilator that is used to measure the depth of a body cavity, and in one embodiment with the use of a cuttable fixture inserted into an initially enlarged dilator retractor made from a cuttable material the excess of the dilator retractor is snipped by a commercial cutter. A tool engaging the end of the cannulated dilator provides leverage on the cannulated dilator for rotation as it is forced into the body cavity, a pusher tool provides leverage on the dilator retractor for inserting the dilator retractor into the body cavity. A clamp that fits the top of the dilator retractor serves to support the dilator retractor through an arm to a rigid structure. In an alternate embodiment one of a series of sized dilator retractors are selected commensurate with the measurement attained by the scaled cannulated dilator.
