Publication number: 20170216069Abstract: Feedback systems and methods enhance obstructive and other obesity treatments by presenting feedback regarding patients' actual eating. An ingestion restricting implant body can be deployed along the gastrointestinal tract. In some embodiments, ingestion alters the implant body, which, in turn, generates signals. The generated signals can be used to inhibit unhealthy ingestion by the patient. In other embodiments, the implant body can be altered by signals so as to selectable change the restriction imposed on the gastrointestinal tract, optionally in response to ingestion events, an eating schedule, or the like. The implant body may comprise a gastric band. Sensor signals may be processed to identify ingestion and/or characterize ingestion material, and the results may be displayed on a screen for a patient or coach to view.Type: ApplicationFiled: April 21, 2017Publication date: August 3, 2017Inventors: Ken Wong, John C.

Publication number: 20170035991Abstract: Various embodiments concern a force sensing catheter having a proximal segment containing a proximal hub, a distal segment containing a distal hub, and a spring segment that extends from the proximal segment to the distal segment. The spring segment comprises a plurality of struts connected to both of the proximal and distal hubs. Each strut includes a preformed bend. The struts mechanically support the distal segment in a base orientation with respect to the proximal segment, flex at the preformed bends when the distal segment moves relative to the proximal segment in response to a force, and resiliently return the distal segment to the base orientation once the force has been removed. The catheter further comprises a plurality of sensors configured to output signals indicative of relative movement between the proximal and distal segments for determining a magnitude and direction of the force.Type: ApplicationFiled: August 5, 2016Publication date: February 9, 2017Inventors: Darrell L.

Publication number: 20120316451Abstract: Medical, diagnostic, and/or patient monitoring methods, systems and devices enhance ingestion-related health, often by screening and/or treating patients with eating disorders. Optionally, a gastric electric stimulation (GES) therapy system monitors changes in an obese patients' autonomic balance associated with a stimulation event and/or a meal event by analyzing heart rate variability (HRV) of the patient. These event-based changes in autonomic balance may be used to determine which patients will likely respond to GES therapy, and/or to control the GES therapy administration.Type: ApplicationFiled: December 8, 2011Publication date: December 13, 2012Applicant: IntraPace, Inc.Inventors: Rose Province, Mike Hedman, Matthew Hills, John C.
