The core portion is coupled to the radiopaque element, and includes a first porous matrix defining a first controlled pore architecture. The shell portion is coupled to the core portion and includes a second porous matrix defining a second controlled pore architecture that is different from the first controlled pore architecture. | 03-03-2011 |
20120022380 | METHODS AND APPARATUS FOR ASSESMENT AND TREATMENT OF BODY CAVITIES - Methods and apparatus for detection, assessment and optionally treatment of the cancerous tissue in the natural and manmade body cavities. An expandable cavity assessment device that is coupled with cancer detecting elements is placed in a cavity in close proximity to the site of cancerous tissue. The cavity assessment device may receive an optical fiber, or other type of energy conduit and potentially a radioactive source for interstitial radiation therapy. The cavity assessment device may be equipped with a balloon member coupled with electro conductive elements. Further, a system facilitating substance communication with the internal surface of the cavity is provided. | 01-26-2012 |
20120035503 | METHODS AND DEVICES FOR CUTTING AND COLLECTING SOFT TISSUE - Devices and methods for cutting and collecting a specimen from a mass of tissue. The device may include an integrated cut and collect assembly. The integrated cut and collect assembly includes a cutting portion and a collection portion that includes a flexible membrane. The collection portion of the assembly is attached to the cutting portion thereof. The cutting portion is configured to cut the specimen from the mass of tissue and the collection portion is configured to collect the cut specimen and to encapsulate and isolate the cut specimen within the membrane to enable its safe retraction from the mass of tissue. | 02-09-2012 |
20120076733 | POST-BIOPSY CAVITY TREATMENT IMPLANTS AND METHODS - A post-biopsy cavity treatment implant includes a radiopaque element, a core portion and a shell portion. The core portion is coupled to the radiopaque element, and includes a first porous matrix defining a first controlled pore architecture. The shell portion is coupled to the core portion and includes a second porous matrix defining a second controlled pore architecture that is different from the first controlled pore architecture. | 03-29-2012 |
20120130489 | METHODS AND APPARATUS FOR IN SITU FORMATION OF SURGICAL IMPLANTS - Methods, devices and systems for in situ formation of an implant within a post-surgical cavity. A balloon is provided within the cavity and a gelling initiator such as a cross-linking agent is introduced into the balloon. A polymer susceptible to solidifying in the presence of the gelling initiator is then introduced into the balloon. The introduced polymer is allowed solidify through contact with the introduced gelling initiator to form the implant while the balloon isolates the solidifying implant from the cavity. The balloon is then ruptured and extracted from the cavity such that the formed implant remains within and directly contacts an interior surface of the cavity. | 05-24-2012 |
20120184874 | METHODS AND DEVICES FOR REMOVING TISSUE FROM A PATIENT AND PLACING A MARKER IN THE PATIENT - The device is used to remove tissue from a patient and to also place a marker in the patient. The device has an opening through which tissue enters the device. The tissue, which enters the opening is cut and the tissue is removed. The device may be used a number of times to remove a number of tissue masses. The device also includes a marker, which the user may release in the patient at the desired time. | 07-19-2012 |
20120296207 | POST-BIOPSY CAVITY TREATMENT IMPLANTS AND METHODS - An implant for filling a cavity created by an excisional procedure includes first and second portions. The first portion may include a first collagenous matrix that defines a first selected crosslinking density and the second portion may include a second collagenous matrix that defines a second selected cross-linking density that is different than the first cross-linking density. The first and second cross-linking densities may be selected so as to cause the first and second portions to swell in such a manner that the implant swells into a size and a shape that is similar to the predetermined size and shape of the cavity when the implant is implanted. An aqueous solution may be added to the cavity if the cavity is not sufficiently aqueous to cause the implant to swell. | 11-22-2012 |

20130289388 | POST-BIOPSY CAVITY TREATMENT IMPLANTS AND METHODS - An embodiment of a post-biopsy cavity treatment implant includes a first portion including a first porous matrix defining a first controlled pore architecture or crosslinking density, and a second portion coupled to the first portion. The second portion includes a second porous matrix that defines a second controlled pore architecture or a second crosslinking density that is different from the first controlled pore architecture or the first crosslinking density, causing the second portion to swell in a different manner than the first portion when the implant is placed in an aqueous environment. | 10-31-2013 |
20140378873 | METHODS, DEVICES AND SYSTEMS FOR INCREASING THE EFFECTIVENESS OF ULTRASOUND AND OTHER TISSUE TREATMENT MODALITIES - Embodiments isolate exposed surfaces to increase the effectiveness of different treatment modalities. Embodiments isolate hollow spaces within the body to increase the effectiveness of ultrasound energy and/or other treatments. Such hollow spaces within the body may include nasal surfaces, and recessed or sequestered surfaces, e.g. sinus cavity surfaces or other anatomical structures, such as upper and lower gastrointestinal tract, airways, uterine and vaginal cavities and the anorectal canal, for example. Isolating the area to be treated reduces the volume of the enclosed and delimited space and reduces the tissue surface against which the ultrasound and/or biologically active substances act. For example, isolating a hollow passageway within the body enhances the effectiveness of ultrasound within the isolated space, and constrains the biologically active fluid and/or the gel or fluid configured to conducts the ultrasonic energy from the emitter thereof (e.g., an ultrasound waveguide) to the surfaces to be treated. | 12-25-2014 |
