20090125009 | METHODS AND APPARATUS FOR TREATMENT OF HOLLOW ANATOMICAL STRUCTURES - One embodiment comprises an apparatus for applying energy to a hollow anatomical structure having an inner wall. The apparatus comprises an elongate shaft having a distal end and a proximal end opposite the distal end; and a capacitive treatment element located near the distal end. The capacitive treatment element is sized for insertion into the hollow anatomical structure and placement near the inner wall. The capacitive treatment element is configured to create an electric field that extends at least partially into the inner wall. Other devices and methods for treatment of hollow anatomical structures are disclosed as well. | 05-14-2009 |
20090187206 | Conformationally-Stabilized Intraluminal Device for Medical Applications - The invention relates to devices that are stabilized at an intraluminal residence site in the gastrointestinal tract by their conformation, including dimensions of length and curvature. The device as a whole corresponds to the conformation of the residence site; more particularly, the curved or angled portions correspond to the curved or angled portions of the residence site and do not conform to an immediately proximal or distal site. In some embodiments, the conformationally stabilized device may effect a change in the residence site shape that contributes to stability of the device. Some embodiments are directed toward curbing appetite and/or reducing food intake, other embodiments may be directed toward other therapeutic ends. Some embodiments of the device are designed to reside wholly in the duodenum; others reside principally within the duodenum but extend proximally into the gastric antrum, while other embodiments are designed to reside elsewhere within the gastrointestinal tract. | 07-23-2009 |
20090281379 | SYSTEM AND METHOD FOR TRANSLUMINAL ACCESS - A translumenal access system includes a translumenal access catheter, a trocar, and one or more guidewires. The trocar may be introduced through adjacent tissue layers, typically from an endoscope, and the translumenal access catheter introduced through the resulting penetration over the trocar. A balloon on the catheter may be used to dilate the penetration, and an enlarged distal portion of the balloon may be used to draw the tissue layers into apposition. The first stent may be exchanged for the trocar and a second stent may be introduced through a side port on the access catheter. The stents may be then used to introduced catheters or other interventional tools, optionally for delivering one or more stents to the enlarged tissue penetration. | 11-12-2009 |
20090281557 | TISSUE ANCHOR FOR SECURING TISSUE LAYERS - Tissue anchors comprise a woven filament braid body having an elongated tubular configuration and a foreshortened configuration where proximal and distal ends of the body expand radially into double-walled flange structures while leaving a cylindrical saddle region therebetween. The tissue anchors are deployed through penetrations between adjacent tissue layers, where the flanges engage the outer surfaces of the tissue layers and the saddle region resides within the tissue penetrations. | 11-12-2009 |
20110137227 | METHODS AND DEVICES FOR DELIVERING OR DELAYING LIPIDS WITHIN A DUODENUM - Devices are described that are adapted and configured for use within the duodenum of a mammal. One aspect of the device includes a spine having a proximal end and a distal end; an atraumatic feature positioned on at least one of the proximal end and the distal end of the spine; and a flow reduction element positioned along the spine and having a variable porosity along its length. In another aspect, there is a flow reduction device adapted and configured for use within the duodenum of a mammal having a spine having a length, a proximal end and a distal end; a first atraumatic feature positioned adjacent to the spine proximal end; a second atraumatic feature positioned adjacent to the spine distal end wherein the length of the spine is selected so that when the first atraumatic feature is in the stomach the second atraumatic feature is in the fourth portion of the duodenum; and a flow reduction element having a proximal end, a distal end, an interior portion, an exterior portion and a variable porosity between the proximal end and the distal end. Additionally or alternatively, some or all of the components of the device may be formed from or coated with a lipid-philic material. There is also provided a method for adjusting the passage of ingesta through the duodenum of a mammal. The method includes placing the distal end of a flow reduction device in the duodenum of a mammal; placing the proximal end of the flow reduction device in a stomach of the mammal; expanding within the duodenum of the mammal a variable porosity flow reduction element supported by the flow reduction device; and directing at least a portion of the flow of ingesta through the duodenum through the proximal end of the variable porosity flow reduction element and into an interior portion of the variable porosity flow reduction element. | 06-09-2011 |
20110264176 | HOT TIP VEIN THERAPY DEVICE - Methods and apparatus for generating vapor within a catheter are provided which may include any number of features. One feature is generating vapor with an electrode array within a catheter. Another feature is sensing an impedance of the electrode array, and adjusting the power delivered to the electrode array to fully generate vapor within the catheter. Another feature is delivering the vapor to a vein of a patient for vein reduction therapy. | 10-27-2011 |

20130178782 | METHODS AND DEVICES FOR DELIVERING OR DELAYING LIPIDS WITHIN A DUODENUM - Devices and methods described include a flow reduction device adapted and configured for use within the duodenum of a mammal having a spine, a first atraumatic feature, a second atraumatic feature, and a flow reduction element having a proximal end, a distal end, an interior portion, an exterior portion and a variable porosity between the proximal end and the distal end. One aspect of the device includes a spine having a proximal end and a distal end, an atraumatic feature positioned on at least one of the proximal end and the distal end of the spine, and a flow reduction element positioned along the spine and having a variable porosity along its length. | 07-11-2013 |
20130289417 | APPARATUS AND METHOD FOR ENDOVASCULAR DEVICE GUIDING AND POSITIONING USING PHYSIOLOGICAL PARAMETERS - Systems and methods for determining the position of an endovascular device within the body are provided. The system can include a catheter having a tip portion that can generate sound waves which can be detected by auscultation devices which allows the position of the catheter tip to be triangulated. The acoustic triangulation system can be used in conjunction with ECG and/or ultrasound information to further refine the location of the catheter tip. | 10-31-2013 |
