Patent application numberDescriptionPublished
20090292322METHOD OF REHABILITATING AN ANULUS FIBROSIS - Systems for minimally invasive disc augmentation include an anulus augmentation component and a nucleus augmentation component. Both are suited for minimally invasive deployment. The nucleus augmentation component restores disc height and/or replaces missing nucleus pulposus. The anulus augmentation component shields weakened regions of the anulus fibrosis and/or resists escape of natural nucleus pulposus and/or the nucleus augmentation component. Methods and deployment devices are also disclosed. Methods of closing a defect in an anulus fibrosus of an intervertebral disc using a barrier are also provided.11-26-2009
20100057143INTERIOR AND EXTERIOR SUPPORT SYSTEM FOR INTERVERTEBRAL DISC REPAIR - Methods of reinforcing anulus fibrosis tissue within an intervertebral disc include the implantation of a repair device comprising one or more support members. The device may be anchored to the surrounding tissue. The device may be compressible and delivered in a minimally invasive manner.03-04-2010
20100204797ANULUS LESION REPAIR - Methods for repairing a damaged or weakened intervertebral disc are disclosed. According to one or more embodiments, a method comprises delivering a support member within an intervertebral disc having an anular defect, anchoring an anchor to a vertebral body adjacent the intervertebral disc, connecting the anchor to the support member, and pulling the support member toward the anchor using the connection.08-12-2010
20100217384Method For Replacing Native Valve Function Of A Diseased Aortic Valve - Methods for replacing native valve function of a diseased aortic valve are disclosed. In an embodiment, a method for replacing native valve function of a diseased aortic valve in a patient includes: (a) receiving an artificial heart valve assembly mounted about a first mounting position on a catheter system, (b) guiding the artificial heart valve assembly through the vasculature of the patient, (c) while the catheter system having the artificial heart valve assembly mounted thereto is in the patient's vasculature, mounting the artificial heart valve assembly about a second mounting position on the catheter system, (d) delivering the artificial heart valve assembly to the region of the diseased aortic valve, (e) expanding the artificial heart valve assembly in the region of the diseased aortic valve, and (f) withdrawing the catheter system from the patient's vasculature.08-26-2010
20100249921Cardiac Valve Procedure Methods and Devices - Devices and methods for performing intravascular procedures without cardiac bypass include embodiments of temporary filter devices, temporary valves, and prosthetic valves. The temporary filter devices have a cannula which provides access for surgical tools for effecting repair of cardiac valves. The cannula may have filters which prevent embolitic material from entering the coronary arteries and aorta. The valve devices may also have a cannula for insertion of the valve into the aorta. The valve devices expand in the aorta to occupy the entire flow path of the vessel and operate to prevent blood flow and to permit flow through the valve. The prosthetic valves include valve fixation devices which secure the prosthetic valve to the wall of the vessel. The prosthetic valves are introduced into the vascular system in a compressed state, advanced to the site of implantation, and expanded and secured to the vessel wall.09-30-2010
20100280540Intravascular Filter with Debris Entrapment Mechanism - Apparatus for filtering and entrapping debris in the vascular system of a patient, the apparatus including a filter to allow blood to flow therethrough and to restrict passage of debris, wherein the filter captures debris carried in a first direction of blood flow. The apparatus further includes an entrapment mechanism which allows passage of debris and blood therethrough, in the first direction of blood flow and prevents debris passage in a second direction. The entrapment mechanism and filter allow blood and debris therethrough in the first direction of blood flow. The entrapment mechanism prevents debris flow in the second direction of blood flow. A method for filtering and entrapping debris in the vascular system includes inserting the apparatus into the vascular system, allowing blood and debris carried therein to flow through the entrapment mechanism, and removing the apparatus and accumulated debris from the vascular system.11-04-2010
20100298837METHODS FOR DELIVERING AN IMPLANT AND AGENT IN AN INTERVERTEBRAL DISC - The present invention relates generally to devices and methods for delivering medical devices, such as implants, to desired tissue sites, such as the intervertebral disc. In one aspect, an intervertebral disc repair and diagnostic device that is minimally invasive and that provides precise access to the desired site is provided. In some aspects, the device and method are adapted to deliver, position and expand implants that are initially oriented and compressed for minimally invasive, yet precise and effective implantation.11-25-2010
20110118830System For Replacing Native Valve Function Of A Diseased Aortic Valve - Methods for replacing native valve function of a diseased aortic valve are disclosed. In an embodiment, a method for replacing native valve function of a diseased aortic valve in a patient includes: (a) receiving an artificial heart valve assembly mounted about a first mounting position on a catheter system, (b) guiding the artificial heart valve assembly through the vasculature of the patient, (c) while the catheter system having the artificial heart valve assembly mounted thereto is in the patient's vasculature, mounting the artificial heart valve assembly about a second mounting position on the catheter system, (d) delivering the artificial heart valve assembly to the region of the diseased aortic valve, (e) expanding the artificial heart valve assembly in the region of the diseased aortic valve, and (f) withdrawing the catheter system from the patient's vasculature.05-19-2011
20110118844METHODS OF REPAIRING HERNIATED SEGMENTS IN THE DISC - Systems for minimally invasive disc augmentation include an anulus augmentation component and a nucleus augmentation component. Both are suited for minimally invasive deployment. The nucleus augmentation component restores disc height and/or replaces missing nucleus pulposus. The anulus augmentation component shields weakened regions of the anulus fibrosis and/or resists escape of natural nucleus pulposus and/or the augmentation component. Methods and deployment devices are also disclosed. Method of supporting and augmenting a nucleus pulposus by inserting a flexible biocompatible material into the disc space using an anchoring means are also provided.05-19-2011
20110125271METHOD OF PERFORMING AN ANCHOR IMPLANTATION PROCEDURE WITHIN A DISC - Methods of performing procedures within an intervertebral disc are disclosed. The methods include performing procedures such as implant delivery, tissue manipulation, tissue diagnostics, and therapeutic and diagnostic agent delivery at selected locations within intervertebral discs. In one embodiment, a method includes delivering an anchor and an implant within a functional spinal unit using a surgical device having at least one depth stop.05-26-2011
