Publication number: 20110087257Abstract: Systems and methods for minimally invasive discectomy procedures are described herein. The systems include a bendable flexible cannula may have a straight configuration suitable for insertion and withdrawal into spinal tissue, and a curved configuration suitable for accessing certain areas of a vertebral disc that may be difficult to reach in the straight configuration. A cannula is straightened by inserting a straight stylet therethrough. The straight stylet may have a deflectable region that facilitates its insertion into the cannula. Removal of a straight stylet from a cannula may allow the cannula to assume its curved configuration. The systems may be used with tissue removal devices, and certain variations of tissue removal devices may comprise a collector for aspiration, as well as a travel limiter to restrict inadvertent motions of the tissue removal devices within a vertebral structure.Type: ApplicationFiled: April 2, 2010Publication date: April 14, 2011Applicant: Spine View, Inc.Inventors: John T.

Patent number: 7169140Abstract: A method of performing a medical procedure is disclosed which involves the use of a balloon catheter in combination with an angioscope to monitor an intravascular stent before, during or after deploying the stent. Specifically, the method may include the steps of (1) delivering an intravascular stent into the vasculature of a patient, (2) positioning a balloon catheter in the vasculature such that the inflatable balloon is adjacent the stent, (3) inserting an angioscope into the balloon catheter such that the distal end of the angioscope is adjacent an optically-transparent tube traversing the interior of the balloon, and (4) visually monitoring the stent before, during or after deploying the intravascular stent. The optically-transparent tube may define a guide wire lumen for use with a guide wire and the angioscope may be inserted into the guide wire lumen. The intravascular stent may be a balloon-expandable stent, a self-expanding stent, or a stent made of a photo-responsive polymer.Type: GrantFiled: September 5, 2000Date of Patent: January 30, 2007Assignee: Boston Scientific Scimed, Inc.Inventor: Stewart M.

Patent number: 6723082Abstract: Apparatus and methods for delivering an angiogenic agent to a site within the heart. Either using a percutaneous, intraoperative or minimally invasive approach, an elongated member containing an angiogenic agent is guided to a heart wall and the agent is dispensed into heart tissue. Additional fluids or substances can be dispensed in combination with the angiogenic agent to provide visualization and site mapping. In certain embodiments, the angiogenic agent is delivered adjunctively with the administration of energy, such as laser energy or RF energy which disturbs the heart tissue sufficiently to enhance the effects of the angiogenic agent.Type: GrantFiled: September 27, 1999Date of Patent: April 20, 2004Inventors: Sam G. Payne, Randy J. Kesten, Michael Aita, Stewart M. Kume, Stephen B. Pearce, Manuel A. Javier, Jr.

Patent number: 6599230Abstract: An intravascular radiation delivery system including a catheter, a radiation source disposed in an open-ended lumen in the catheter and a closed-ended sheath surrounding the radiation source so as to prevent blood and other fluids from coming into contact with the radiation source. Preferably, the open-ended lumen is centered in the balloon for uniform radiation delivery. The catheter may include a blood perfusion lumen under the balloon or around the balloon. The open-ended lumen in the catheter may have a reduced diameter adjacent the distal end of the catheter to prevent the radiation source from exiting the lumen. Methods of using the radiation delivery system are also disclosed. An alternative method of delivering radiation to a treatment site inside the vasculature of a patient using a gas-filled balloon catheter and a radiation source disposed in the balloon catheter. The treatment site is exposed to radiation, preferably beta radiation, through the gas-filled balloon.Type: GrantFiled: March 14, 2001Date of Patent: July 29, 2003Assignee: SciMed Life Systems, Inc.Inventors: Roger N. Hastings, Thomas R. Hektner, Stewart M. Kume
