Publication number: 20120245695Abstract: A spinal implant which is configured to be deployed between adjacent vertebral bodies. The implant has at least one extendable support element with a retracted configuration to facilitate deployment of the implant and an extended configuration so as to expand the implant and effectively distract the disc space, stabilize the motion segments and eliminate pathologic spine motion. Angular deformities can also be corrected, and natural curvatures restored. Preferably, the implant has a minimal dimension in its unexpanded state that is smaller than the dimensions of the neuroforamen through which it typically passes to be deployed within the intervertebral space. The implant is provided with a locking system preferably having a plurality of locking elements to lock the implant in an extended configuration.Type: ApplicationFiled: June 1, 2012Publication date: September 27, 2012Applicant: COALIGN INNOVATIONS, INC.Inventors: Philip J.

Publication number: 20120130387Abstract: An insertion handle for medical implants includes a handle with an elongate shaft extending therefrom and connection means for the implant disposed at the end of the shaft opposite the handle. The connection means includes a pivotable attachment for the implant that is controlled remotely from the handle. Both angle of the implant with respect to the handle and shaft as well as the attachment may be separately controlled and adjusted. Remote angular adjustment facilitates insertion of implants in to small surgical sites because the orientation of the implant may be repeatedly, remotely adjusted as the implant is inserted. Connectors may also be provided at the engagement surface between the handle and implant in order to provide communication with the implant or surgical site. The connectors also may serve as torque bearing members to avoid the need for separate torque bearing means such as keyways and the like.Type: ApplicationFiled: April 15, 2010Publication date: May 24, 2012Applicant: COALIGN INNOVATIONS, INC.Inventors: Philip J.

Patent number: 7811293Abstract: A method and system are disclosed for rapid placement of tubes within a body cavity that includes placing a compliant cannula over a probe tip of a cutting device until the probe tip extends beyond the cannula, incising the tissue covering body cavity to create an opening therein, inserting the probe tip of the cutting device until the cannula placed thereon extends into the incision, removing the probe tip while leaving the cannula inserted within the incision, introducing a distal end or tip of a tube into the cannula a predetermined distance, and removing the cannula over the tube while retaining the tube in position within the body cavity. The device includes a sealing portion which attaches to the body without sutures and having an opening therethrough, and a tube which passes through the opening of the seal and mates thereto without sutures.Type: GrantFiled: February 2, 2004Date of Patent: October 12, 2010Inventors: Philip J.

Patent number: 6450948Abstract: A steerable probe with a deflectable tip. In one embodiment, the probe may include a cannula having a proximal end and a distal end and extending along a length therebetween, an exterior surface, an interior surface defining a lumen, an elongate flexible section extending along a first portion of the length and having a section proximal end and a section distal end. A pull wire for deflecting the flexible section in a first direction in a preferred bending plane may be substantially embedded in the cannula between the interior surface and the exterior surface and extending from the section proximal end to the section distal end. The pull wire may be secured to the cannula adjacent to the section distal end and freely passing through the section proximal end. Two longitudinal strengthening members may be embedded in and extend along the flexible section generally opposite each other about the preferred bending plane.Type: GrantFiled: November 2, 1999Date of Patent: September 17, 2002Assignee: Vista Medical Technologies, Inc.Inventors: David G.

Patent number: 6183461Abstract: A drug-infusing device is implanted into a body cavity such as a bladder. The device is implanted in an uninflated, low profile state. After insertion into the body cavity, the device is filled with a substance, such as a drug, and assumes an increased profile. After the device is filled, it is allowed to float freely within the body cavity. Alternatively, the device can be tethered to a wall of the body cavity. The device delivers the drug at a controlled rate over an extended period of time. In order to deliver the drug at a controlled rate, the device preferably has a pressure-responsive valving member. The flow resistance of the valving member is responsive to the pressure at which the drug is stored within the infusing device. The resistance of the valving member decreases as the pressure within the infusing device decreases, thereby providing a resultant controlled flow rate.Type: GrantFiled: September 14, 1999Date of Patent: February 6, 2001Assignee: Situs CorporationInventors: David G. Matsuura, Walter Dean Gillespie, John Patrick Greelis, Charles Lowell Parsons, Mikxay Sirivong, Paul F. Zupkas
