Patent application numberDescriptionPublished
20080306447Systems and methods employing a bite block insert for positioning and stabilizing external instruments deployed within the body - Systems and methods are provided for positioning and stabilizing an external instrument during insertion of the instrument through the oral cavity (e.g., insertion of a catheter through the oral cavity and into the esophagus or cardia for treatment of gastroesophageal reflux disease (GERD)). The systems and methods provide a gripping tool for association with a bite block, capable of selectively moving between an open position in which the instrument may be inserted or removed, and a closed position in which the external instrument is held in a fixed position.12-11-2008
20090012421Systems and methods for treating tissue regions of the body - Systems and methods deploy a therapeutic or diagnostic element into contact with a body tissue region. The systems and methods can sense position of the therapeutic or diagnostic element relative to a targeted tissue region without direct or indirect visualization, by sensing fluid pressure in a fluid path having an outlet located at or near the therapeutic or diagnostic element. The systems and methods can also inflate the therapeutic or diagnostic element during use, while taking steps to avoid over-inflation and/or while dynamically monitoring the pressure conditions within the expanded element.01-08-2009
20090043302Systems and methods for treating tissue regions of the body - Systems and methods deploy an electrode from a catheter assembly. The systems and methods provide a catheter handle having a trigger lever adapted to carry an actuator rod. The actuator rod is adapted to cause movement of the electrode between a retracted position and an extended position. A pinion is carried by the trigger lever for engagement with a rack carried by the actuator rod. Compression of the trigger lever moves the rack along the actuator rod between a first position corresponding to the electrodes being in the retracted position and a second position corresponding to either the primed electrode firing position or the electrodes being in an extended position.02-12-2009
20090082721Systems and methods for applying a selected treatment agent into contact with tissue to treat sphincter dysfunction - Systems and methods apply a selected treatment agent or agents into contact with tissue at or in the region of a dysfunctional sphincter (in the case of GERD, fecal incontinence, or other dysfunctional sphincter disorders) to affect improved sphincter barrier function and/or to disrupt abnormal nerve pathways. The treatment agent can include at least one cytokine and/or at least one tissue bulking agent and/or at least one vanilloid compound to evoke a desired tissue response. The systems and methods can be used a primary treatment modality, or applied as a supplementary treatment before, during or after a primary intervention.03-26-2009
20090118699Systems and methods for treating obesity and other gastrointestinal conditions - Systems and methods affect tightening of the pyloric sphincter and/or serve to mediate or moderate receptive relaxation of muscles in the stomach, to treat or mitigate various physiologic conditions, such as obesity, biliary reflex, GERD, and/or Barrett's esophagus. The systems and methods may be used as either a primary treatment modality, or applied as a supplementary treatment before, during or after a primary intervention.05-07-2009
20100004648Method to treat gastric reflux via the detection and ablation of gastro-esophageal nerves and receptors - A method of treating a sphincter provides a sphincter electropotential mapping device with at least one of a mapping electrode or a treatment electrode. The sphincter electropotential mapping device is introduced into at least a portion of the sphincter, the lower esophageal sphincter, stomach, the cardia or the fundus. Bioelectric activity causing a relaxation of the sphincter is detected and energy is delivered from either the mapping electrode or the treatment electrode to treat the bioelectric activity. A method of treating a sphincter provides a sphincter electropotential mapping device with at least one of a mapping electrode or a treatment electrode. The sphincter electropotential mapping device is introduced into at least a portion of the sphincter, the lower esophageal sphincter, stomach, the cardia or the fundus. Bioelectric activity causing a relaxation of the sphincter is detected and energy is delivered from either the mapping electrode or the treatment electrode to treat the bioelectric activity.01-07-2010
20100057080Devices, systems and methods for treating tissue regions of the body - Improved devices, systems and methods for treating a tissue region provide straightforward, yet reliable ways for installing diverse functional components within the confined space of a catheter-based instrument.03-04-2010
20100217197System and methods employing a bite block insert for positioning and stabilizing external instruments deployed within the body - Systems and methods are provided for positioning and stabilizing an external instrument during insertion of the instrument through the oral cavity (e.g., insertion of a catheter through the oral cavity and into the esophagus or cardia for treatment of gastroesophageal reflux disease (GERD)). The systems and methods provide a gripping tool for association with a bite block, capable of selectively moving between an open position in which the instrument may be inserted or removed, and a closed position in which the external instrument is held in a fixed position.08-26-2010
20100249775Systems and methods employing a guidewire for positioning and stabilizing external instruments deployed within the body - Systems and methods for treating a tissue region employ an expandable structure projecting beyond the distal end of a catheter tube. A distal tail projects beyond the far end of the basket assembly. The distal tail includes a guidewire lumen that accommodates passage of a guidewire without threading the guidewire through the catheter tube.09-30-2010
20110071468Systems and methods for applying a selected treatment agent into contact with tissue to treat sphincter dysfunction - Systems and methods apply a selected treatment agent or agents into contact with tissue at or in the region of a dysfunctional sphincter (in the case of GERD, fecal incontinence, or other dysfunctional sphincter disorders) to affect improved sphincter barrier function and/or to disrupt abnormal nerve pathways. The treatment agent can include at least one cytokine and/or at least one tissue bulking agent and/or at least one vanilloid compound to evoke a desired tissue response. The systems and methods can be used a primary treatment modality, or applied as a supplementary treatment before; during or after a primary intervention.03-24-2011
20110077550Systems and methods for treating tissue regions of the body - Systems and methods deploy a therapeutic or diagnostic element into contact with a body tissue region. The systems and methods can sense position of the therapeutic or diagnostic element relative to a targeted tissue region without direct or indirect visualization, by sensing fluid pressure in a fluid path having an outlet located at or near the therapeutic or diagnostic element.
