20140221969 | Endoscopic Injection Needle Device - An endoscopic injection needle device includes a flexible elongate sheath attached to a handle. Disposed within the sheath is drive shaft having a lumen within and a needle at its distal end. The drive shaft is movable longitudinally within the sheath and is attached at its proximal end within the handle to an actuator. Advancing the actuator extends the needle from the distal end of the device. The actuator includes a locking mechanism that locks it in place with the handle when advanced a certain distance. The locking mechanism includes multiple locking positions wherein the exposed length of the needle corresponds to the distance advanced by the actuator at each locking position. Also included in the distal end of the sheath are a spring coil and a collar. The collar is positioned distal to the spring coil and includes a dome shaped distal end that extends beyond the distal end of the sheath. The drive shaft extends through the spring coil and, when retracted, the needle is housed within the collar. The spring coil and collar stabilize the distal end of the sheath, facilitating consistent deployment and retraction of the needle. | 08-07-2014 |
20140222014 | Surgical Snare Device - A surgical snare device for use in polypectomy procedures includes a snare loop capable of being deployed with a plurality of precise internal diameters. The device includes a handle with first and second handle assemblies and a collar. The first handle assembly has multiple numerical markings on a side. The second handle assembly is slidable along the first handle assembly to deploy the snare loop from an elongate tubular sheath attached to the distal end of the first handle assembly. When the second handle assembly is slid to a position such that it aligns with one of the numerical markings on the first handle assembly, the snare loop will be deployed with an internal diameter in millimeters that corresponds precisely to the numerical marking. For example, sliding the second handle assembly to a ‘10’ marking will deploy a snare loop having an internal diameter of 10 mm. The collar is positioned just distal to the second handle assembly and is also slidable along the first handle assembly. The collar functions as a depth stop and prevents further distal movement of the second handle assembly. | 08-07-2014 |
20140320617 | Video Processing In A Compact Multi-Viewing Element Endoscope System - The present specification is directed towards endoscopes, such as colonoscopes, that provide a broader field of view and allow extended access of surgical tools and also enable efficient packing of all necessary elements in the tip section, while maintaining their functionality. Also described are methods and systems for capturing and displaying still and video images using an endoscope corresponding to a left-side looking, a front-looking and a right-side looking viewing element of an endoscopic tip generated in a native aspect ratio. | 10-30-2014 |
20140333743 | Operational Interface in a Multi-Viewing Element Endoscope - The present specification describes an endoscopy display system including an endoscope with a distal tip having at least three image capturing components, and a handle with an actuator that, when activated, generates a video processing command; a controller including a video processing system adapted to transmit commands to the three image capturing components and receive an image feed from each of said three image capturing components; and a display system, including at least one monitor that concurrently receives and concurrently visually displays each of said processed image feeds, where the video processing system is adapted to process each of said image feeds in accordance with the video processing command to cause at least one of changing a position of, zooming into or out of; recording; freezing; highlighting; or superimposing a navigation indicator upon the at least one of the processed image feeds. | 11-13-2014 |
20150196192 | Compact Monitor Stand - The present specification provides an apparatus for supporting one or more monitors. The apparatus includes a base stand having one or more wheels for enabling movement of the apparatus; a first rigid frame having a top end and a bottom end attached with the base stand; a second extendable frame having a top end and a bottom end and telescopically movable within the first rigid frame; a monitor arm assembly removably coupled with the top end of the second frame and configured to receive a plurality of monitors. The apparatus is transformable from a first collapsed configuration for transport and storage into a second operational configuration by rotating or removing the monitor arm assembly and by moving the second extendable frame relative to the first rigid frame. | 07-16-2015 |
20150208900 | Interface Unit In A Multiple Viewing Elements Endoscope System - An interface unit is configured to functionally associate with an endoscope system which includes at least two simultaneously operating imaging channels associated with at least two displays, respectively. In a first configuration, the interface unit includes an image processor functionally associated with the at least two imaging channels which is configured to separately synchronize images and image data received simultaneously from the at least two imaging channels and send those discrete image streams to different displays. In a second configuration, the interface unit includes an image processor functionally associated with the at least two imaging channels which is configured to receive image streams, synchronize the image streams, and create a single image stream to send to a display. | 07-30-2015 |

20160081702 | Method of Attaching A Mesh to A Coated Loop Member of A Surgical Snare Device - There is provided herein, a method of attaching a mesh to a loop member, which includes covering a wire with a layer, manipulating the wire along with the layer to form the loop member, wherein the loop member has a shape, placing the mesh over the loop member, wherein portions of the mesh extend beyond a circumference of the loop member, transferring heat to the layer to cause it to partially melt and become tacky, allowing the mesh to fuse with the tacky layer and form a secure bond on cooling, and trimming portions of the mesh extending beyond the circumference of the loop member. A retrieval device formed by the method includes the loop member and attached mesh positioned and longitudinally movable within a tubular sheath. The loop member and mesh are deployed to capture a target object and partially retracted for removal of the object. | 03-24-2016 |
