Filed:

Jun 5, 2009

Appl. No.:

12/479072

Inventors:

Christopher U. Phan - San Leandro CA, US
David M. Schummers - San Francisco CA, US

Assignee:

KYPHON SARL - Neuchatel

International Classification:

A61B 17/70
A61B 17/88

US Classification:

606248, 606279

Abstract:

Multi-level interspinous implants and methods of using the implants with the implants generally include a first member for placement in a first interspinous space and a second member for placement in a second interspinous space. An elongated connector extends from one of the members and is sized to fit in a slot in the other member. Each of the first and second members may include a distal wing, a body, and a proximal wing. The members may also be positioned in a closed orientation for insertion into the patient and a deployed orientation with the distal and proximal wings extending outward along lateral sides of respective spinous processes. The connector may extend outward from the proximal wing of one of the members and away from the other member when that member is in the closed orientation. The connector may be rotated and inserted into the slot where it is secured when that member from which is extends is moved to the deployed orientation.

International Classification:

A61B 17/70

US Classification:

606247

Abstract:

Implementations described and claimed herein provide a distal leading portion of a composite spinal implant for implantation in a spinal facet joint. In one implementation, the distal leading portion includes a distal leading end, a proximal trailing end, a first face, and a second face. The distal leading end has a distal surface generally opposite a proximal surface of the proximal trailing end. The first face has a first surface that is generally parallel with a second surface of the second face. The first and second faces extend between the distal leading end and the proximal trailing end, such that the first and second surfaces slope upwardly from the distal lead end to the proximal trailing end along a length of extending proximally. The first and second surfaces having one or more textured features adapted to provide friction with the spinal facet joint.

Abstract:

An object sizing system sizes an object positioned within a patient. The object sizing system identifies a presence of the object. The object sizing system navigates an elongate body of an instrument to a position proximal to the object within the patient. An imaging sensor coupled to the elongate body captures one or more sequential images of the object. The instrument may be further moved around within the patient to capture additional images at different positions/orientations relative to the object. The object sizing system also acquires robot data and/or EM data associated with the positions and orientations of the elongate body. The object sizing system analyzes the captured images based on the acquired robot data to estimate a size of the object.

Abstract:

A method is described for performing a percutaneous operation on a patient to remove an object from a cavity within the patient. The method includes advancing a first alignment sensor into the cavity through a patient lumen. The first alignment sensor provides its position and orientation in free space in real time. The alignment sensor is manipulated until it is located in proximity to the object. A percutaneous opening is made in the patient with a surgical tool, where the surgical tool includes a second alignment sensor that provides the position and orientation of the surgical tool in free space in real time. The surgical tool is directed towards the object using data provided by both the first and the second alignment sensors.

Abstract:

Systems and methods for performing concomitant medical procedures are disclosed. In one aspect, the method involves controlling a first robotic arm to insert a first medical instrument through a first opening of a patient and controlling a second robotic arm to insert a second medical instrument through a second opening of the patient. The first robotic arm and the second robotic arm are part of a first platform and the first opening and the second opening are positioned at two different anatomical regions of the patient.
