| 20090124927 | Endoscopic system for lung biopsy and biopsy method of insufflating gas to collapse a lung - An endoscopic biopsy system comprising a means for drawing a sample to be sealed, separated, and/or collected towards an instrument, such as a structure that includes one or more of: an extendable wire, an extendable mast, an extruded tube with at least one opening and a vacuum therein, a pivot point, a hinge, and a mounting block. The system should have a means to transfer energy to a sample after a sample is grasped, such as a conducting wire or an anvil. The system should also have an airtight means to remove a separated sample from a biopsy site for analysis, such as a collection bag or an internal vacuum suction system. The endoscopic biopsy system can be used in a method of obtaining a biopsy from the thoracic cavity that includes a step of insufflating gas to induce pneumothorax and collapse a lung. | 05-14-2009 |
| 20090270907 | Retrievable urethra sparing prosthetic stent and kidney stone intervention system - The present invention provides devices, a system, and a method for removing kidney stones from the urinary system of a patient with reduced pain and expenses. The system includes expandable, elongated balloon sheaths that deliver and retrieve forceps and a urethral sparing prosthetic stent. The stent is reconstrainable with interwoven nylon strands that are strategically positioned amongst the struts to ensure smooth collapse for removal. An atraumatic coating of PTFE or PET lining on the stent extends from the struts through the tip of the penis to assist patients in passing stones while the stent is in place at the bladder neck. The stent can stay in place for several days while permitting urine drainage. The basket-shaped forceps device has multiple curved, rigid arms to dilate the urethra and capture occluded or embedded stones with a built-in camera. The method is for removing stones through a protected urethral canal. | 10-29-2009 |

| 20080208230 | EXPANDABLE ROTATING DEVICE AND METHOD FOR TISSUE ASPIRATION - An apparatus and method for removing tissue and/or other material from a patient includes a shaft and a tissue disrupting mechanism operatively coupled to the shaft. The shaft may be coupled to a handpiece or a robotic or remote-controlled system. The mechanism may comprise a rotatable or other movable element having a distal portion with fixed or adjustable radial dimensions. The mechanism may have one or more tissue cutting, chopping, grinding, emulsifying or disrupting features with an adjustable outer diameter for removing substantial tissues. The apparatus may be configured to urge or draw substantial material into the device upon rotation or other movement of the shaft and/or tissue, and may optionally be coupled to sources of suction or aspiration. A radiofrequency or other energy source is optionally included for tissue ablation or other tissue remodeling effects, and/or to enhance coagulation. | 08-28-2008 |
| 20090062871 | BALLOON CANNULA SYSTEM FOR ACCESSING AND VISUALIZING SPINE AND RELATED METHODS - Balloon cannula systems may be used for accessing and visualizing the spine and related methods of treatment, including a forward-looking balloon system for creating a working space and the balloon system having atraumatic dissection capability to allow visualization in spine. The devices and methods described may be used, for example, to perform annulus repair, herniated disc excision, and denervation of neurological tissue; to dispense pharmacological agents and/or cell or tissue therapy agents; to diagnose disc degeneration and bony degeneration, spinal stenosis, and nucleus decompression, and to perform disc augmentation. | 03-05-2009 |
| 20090062872 | BALLOON CANNULA SYSTEM FOR ACCESSING AND VISUALIZING SPINE AND RELATED METHODS - Balloon cannula systems may be used for accessing and visualizing the spine and related methods of treatment, including a forward-looking balloon system for creating a working space and the balloon system having atraumatic dissection capability to allow visualization in spine. The devices and methods described may be used, for example, to perform annulus repair, herniated disc excision, and denervation of neurological tissue; to dispense pharmacological agents and/or cell or tissue therapy agents; to diagnose disc degeneration and bony degeneration, spinal stenosis, and nucleus decompression, and to perform disc augmentation. | 03-05-2009 |
| 20090216284 | BALLOON CANNULA SYSTEM FOR ACCESSING AND VISUALIZING SPINE AND RELATED METHODS - Balloon cannula systems may be used for accessing and visualizing the spine and related methods of treatment, including a forward-looking balloon system for creating a working space and the balloon system having atraumatic dissection capability to allow visualization in spine. The devices and methods described may be used, for example, to perform annulus repair, herniated disc excision, and denervation of neurological tissue; to dispense pharmacological agents and/or cell or tissue therapy agents; to diagnose disc degeneration and bony degeneration, spinal stenosis, and nucleus decompression, and to perform disc augmentation. | 08-27-2009 |
| 20100076476 | SYSTEMS AND METHODS FOR CABLE-BASED TISSUE REMOVAL - Systems and methods for treating disc herniation include surgical and endoscopic access and removal of disc tissue. The tissue removal devices that may be used include flexible elongate members, such as a cable, that may be inserted into a vertebral disc and rotated to pulverize the disc material and facilitate its removal. | 03-25-2010 |
| 20100191057 | PENETRATING MEMBER WITH DIRECT VISUALIZATION - Systems and methods for accessing the spine include tissue penetrating members with direct visualization capability that may be used to form an access pathway to a targeted treatment site. The direct visualization capability, which may be provided by fiberoptic illumination and imaging components, may be use to visualize the tissue as the access pathway is formed by the tissue penetrating member. The tissue penetrating members include catheters and cannulas with sharpened tips with integrated fiberoptic components and/or channels in which a fiberscope or miniscope may be inserted. Apertures and/or transparent materials are provided to permit imaging of tissue about the distal end of the tissue penetrating member. | 07-29-2010 |
