| 20100145352 | HOOD METHOD AND DEVICE FOR ENDOSCOPIC SUBMUCOSAL DISSECTION - A medical device and a method of using such medical device for removing targeted tissue from a body lumen in a patient is presented. The method generally comprises placing the distal end of the device through a natural orifice in the patient to a location that is proximate to the targeted tissue; deploying a T-anchor fastened to a suture strand through the targeted tissue; deploying a loop anchor into the tissue of the body lumen spaced away from the targeted tissue, whereas the suture strand is slidably received by the loop anchor; applying tension to the suture strand; cutting the tissue at a predetermined depth around the periphery of the targeted tissue; and removing the targeted tissue along with the T-anchor from the body lumen. The tension applied to the targeted tissue maintains the targeted tissue in a raised position and/or allows the physician to manipulate the targeted tissue relative to the tissue that is proximate to it. | 06-10-2010 |
| 20090093823 | Devices, Systems and Methods Useable for Treating Sinusitis - Sinusitis and other disorders of the ear, nose and throat are diagnosed and/or treated using minimally invasive approaches with flexible or rigid instruments. Various methods and devices are used for remodeling or changing the shape, size or configuration of a sinus ostium or duct or other anatomical structure in the ear, nose or throat; implanting a device, cells or tissues; removing matter from the ear, nose or throat; delivering diagnostic or therapeutic substances or performing other diagnostic or therapeutic procedures. Introducing devices (e.g., guide catheters, tubes, guidewires, elongate probes, other elongate members) may be used to facilitate insertion of working devices (e.g. catheters e.g. balloon catheters, guidewires, tissue cutting or remodeling devices, devices for implanting elements like stents, electrosurgical devices, energy emitting devices, devices for delivering diagnostic or therapeutic agents, substance delivery implants, scopes etc.) into the paranasal sinuses or other structures in the ear, nose or throat. Specific devices (e.g., tubular guides, guidewires, balloon catheters, tubular sheaths) are provided as are methods for manufacturing and using such devices to treat disorders of the ear, nose or throat. | 04-09-2009 |

| 20090125036 | DEVICES AND METHODS FOR SELECTIVE SURGICAL REMOVAL OF TISSUE - Methods and apparatus are provided for selective surgical removal of tissue. In one variation, tissue may be ablated, resected, removed, or otherwise remodeled by standard small endoscopic tools delivered into the epidural space through an epidural needle. The sharp tip of the needle in the epidural space, can be converted to a blunt tipped instrument for further safe advancement. The current invention includes specific tools that enable safe tissue modification in the epidural space, including a barrier that separates the area where tissue modification will take place from adjacent vulnerable neural and vascular structures. A nerve stimulator may be provided to reduce a risk of inadvertent neural abrasion. | 05-14-2009 |
| 20130060258 | Endoluminal Surgical Instrument for Stapling, Cutting and Dividing - A device for cutting, stapling and dividing the bowel allowing surgery to be performed laparoscopically and associated method of use. The device is inserted transanally and positioned within the bowel, ligatures secure the bowel to the device. The bowel is then cut by the device while securing the open end to minimize spillage and the bowel stapled. The bowel can be re-attached using additional staples and further cuts made to allow the device to be removed. | 03-07-2013 |
| 20100049208 | APPARATUS AND METHODS FOR REMOVING LYMPH NODES OR ANCHORING INTO TISSUE DURING A TRANSLUMENAL PROCEDURE - The present embodiments provide apparatus and methods suitable for removing lymph nodes or providing a tissue anchor during a translumenal procedure. In one embodiment, an apparatus suitable for facilitating removal of a lymph node comprises an expandable device including at least one deployable member having contracted and expanded states. The deployable member may be delivered in the contacted state to a location distal to the lymph node using an insertion tool adapted to be disposed beyond the lymph node. In the expanded state, the deployable member comprises a configuration sized to at least partially circumferentially surround and engage the lymph node. In an alternative embodiment, the deployable member may anchor into an outer portion of a visceral wall to promote stabilization of a system during a medical procedure | 02-25-2010 |
| 20090287221 | Tissue Modification Device and Methods of Using the Same - The present disclosure is directed to a device for excising tissue including an outer hollow member having a lumen communicating with a distal opening. The device also includes an elongate member having a longitudinal axis and a distal end, the elongate member being longitudinally movable within the outer hollow member lumen such that the distal end of the elongate member can be moved from a first configuration distal to the outer hollow member distal opening and a second configuration more proximal to the outer hollow member distal opening. Further, the device includes at least one grasping member hingedly disposed about a distal portion of the elongate member along a generally longitudinal axis, wherein movement of the elongate member from the first configuration to the second configuration can cause displacement of the at least one grasping member about the generally longitudinal axis. | 11-19-2009 |
| 20100185208 | MECHANICAL PUMP FOR REMOVAL OF FRAGMENTED MATTER AND METHODS OF MANUFACTURE AND USE - Material transport catheters and methods for their use rely on rotation of an impeller within a catheter body and a clearing element for preventing buildup of materials at the opening of the catheter body. The impeller preferably comprises an inner tube or shaft having a helical rotor formed over an outer surface thereof. The clearing element may comprise a free end of a structure near the distal end of the catheter body for disrupting clot, wherein the free end of the structure extends into the distal opening of the catheter body to break up materials as the impeller is rotated. Alternatively, the clearing element may comprise a cutting member disposed at the distal opening of the catheter body. | 07-22-2010 |
| 20100331853 | INTRACORPOREAL GRASPING DEVICE - An intracorporeal grasping device includes a tubular member for entering a lumen of a human body and the tubular member having a distal end portion. An elongated core member is disposed within the interior cavity of the tubular member for rotational or slidable movement within the tubular member and the elongated core member having a proximal end portion and a distal end portion. The elongated core member includes a grasping configuration for capturing an object (e.g., clot or debris) therein. | 12-30-2010 |
| 20100262159 | Breast surgery method and apparatus - A surgical apparatus for cutting a tissue mass comprising an elongated housing having a distal portion, a rotatable shaft positioned in the elongated housing, and a plurality of flexible electrocautery cutting blades extending from the housing, wherein the plurality of cutting blades are radially expandable from a first position defining a first diameter to a second larger diameter and the blades are rotatable and transmit electrical energy to cut the tissue mass. | 10-14-2010 |
