20130079580 | RADIATION CATHETER WITH MULTILAYERED BALLOON - A catheter device for irradiating tissue surrounding a body site within a body of a patient, includes an elongated shaft which has a distal portion configured to be deployed within the body site. A treatment location at the distal portion has one or more radiation guides configured to receive a radiation source to irradiate tissue at least in part surrounding the body site. An inflatable multilayered balloon is located to surround the treatment location with a wall thereof having at least two layers including a first layer separate from, inside, and in contact with a second layer around an entire periphery of the first layer, and each of the first layer and the second layer being secured to the distal portion of the elongated shaft. | 03-28-2013 |
20130079664 | BIOPSY DEVICE WITH FLUID DELIVERY TO TISSUE SPECIMENS - The invention is directed to a system and method for separating and collecting one or more tissue specimens from a target site within a patient and flushing the specimen to remove blood, debris and the like before the specimen is removed from the biopsy device. The flow of flushing fluid to the tissue collector is preferably controlled to coincide with delivery of one or more specimens to the collecting tray or basket of the device or after the receipt of the specimen within the tissue collector to ensure that the fluid is applied to a fresh specimen. The tissue tray or basket within the tissue collector has an open or foraminous portion to facilitate removal of fluid, such as the applied fluid and blood, and other debris from the tissue specimens on the tray. Vacuum is provided within the tissue collector, preferably under the tray to remove fluid and debris from the collector interior. | 03-28-2013 |
20130123829 | MRI DETECTABLE OBTURATOR - An obturator for marking an intracorporeal site includes an elongated shaft having an inner lumen, a proximal end, and a substantially closed distal end, the substantially closed distal end being formed of a penetrable membrane. A stylet has an MRI detectable distal shaft portion configured for removable insertion into the inner lumen of the elongated shaft to a location proximal to the penetrable membrane. The MRI detectable distal shaft portion is configured to not interfere with magnetic resonance imaging of tissue proximate thereto. | 05-16-2013 |
20130123831 | TEMPORARY CATHETER FOR BIOPSY SITE TISSUE FIXATION - Devices and methods are provided for temporarily maintaining access to a body cavity in a targeted tissue region within a patient's body. A catheter for temporarily at least partially filing a body cavity in a targeted tissue region within a patient's body includes a shaft having a distal end, a proximal end, and a cavity filling member on a distal shaft section configured to at least partially fill the body cavity. A proximal shaft section is configured to be folded so as to be subcutaneously deployed within the patient when the cavity filling member is disposed within the body cavity so as to prevent intrusion of bacteria. An anti-bacterial material is applied to or incorporated within a surface of the shaft and the cavity filling member so as to prevent bacteria growth. | 05-16-2013 |
20130138014 | BIOPSY DEVICE WITH APERTURE ORIENTATION AND IMPROVED TIP - A biopsy device includes an elongated probe having a central longitudinal axis, a proximal end, a distal end, and an aperture. A tissue penetrating tip includes a proximal base secured to the distal end of the probe. A sharp distal point distal to the proximal base lies on the central longitudinal axis. Each of a first, second and third concave surface is configured to extend from the base to the sharp distal point. The second concave surface is located to intersect the first concave surface to form a first curved cutting edge. A third concave surface is located to intersect the first concave surface to form a second curved cutting edge and is located to intersect the second concave surface to form a third curved cutting edge. Each curved cutting edge extends from the base to the sharp distal point. A tissue cutting device is coaxial with the probe. | 05-30-2013 |
20130144105 | MULTILUMEN BRACHYTHERAPY BALLOON CATHETER - The disclosure describes a device for asymmetrical irradiation of a body cavity or site, such as after removal of tissue, e.g. biopsy or lumpectomy. The device includes an elongated tubular shaft having an inner lumen and a tubular wall with a plurality of lumens extending within the wall which are configured for receiving a radiation source. The distal portion of the tubular shaft is cut into a plurality of longitudinally separated wall segments with a lumen extending within at least one of the wall segments. A support member is positioned within the separated wall segments to support and position the wall segments in a desired configuration for brachytherapy. An expandable member such as an inflatable balloon is mounted on the distal shaft portion about the separated wall segments wall which when inflated secures the distal shaft portion within a desired intracorporeal site for brachytherapy treatment. | 06-06-2013 |
20130144157 | MARKER DELIVERY DEVICE WITH RELEASABLE PLUG - A marker delivery device includes an elongated delivery cannula which has a distal end section, an inner lumen and a discharge opening in the distal end section in communication with the inner lumen. At least one elongated fibrous marker body is slidably disposed within the inner lumen of the elongated delivery cannula. The at least one elongated fibrous marker body includes a plurality of bioabsorbable polymeric strands. The strands are compressed to a compressed configuration and bound together in the compressed configuration with a polymer binding agent prior to insertion into the elongated delivery cannula. | 06-06-2013 |
20130184560 | GUIDE BLOCK FOR BIOPSY OR SURGICAL DEVICES - A guide block for an MRI device has a block body with a proximal face, a distal face, and a plurality of passageways extending between the two faces. A first guide passageway within the guide block is open along the body length, extends between the proximal face and the distal face, and is configured to receive a tissue-removing device. A second guide passageway within the guide block is open along the body length, extends between the proximal face and the distal face, and is configured to receive the tissue-removing device. A longitudinal opening extends between the first guide passageway and the second guide passageway, and is coextensive with the first guide passageway and the second guide passageway between the proximal face and the distal face. | 07-18-2013 |
