Publication number: 20110295180Abstract: Methods and devices create an intestinal braking effect, are non-invasive or minimally invasive, and may be reversible. These methods and devices are accomplished via stabilized implantable systems, and ingestible pills. In one embodiment, the implantable system comprises a device delivering a therapeutic substance to a target location within the gastrointestinal tract of a patient in order to initiate an intestinal braking effect which would promote sensations of satiety and stimulate excess weight loss for the patient.Type: ApplicationFiled: May 11, 2011Publication date: December 1, 2011Inventors: Thomas E.

Patent number: 8066629Abstract: An apparatus is operable to communicate fluid. An exemplary apparatus comprises a housing and a fluid reservoir within the housing. An actuator is operationally engaged with the fluid reservoir. The actuator is operable to effect communication of fluid from or into the fluid reservoir. A sensor is in fluid communication with the fluid reservoir. The sensor is operable to sense a physical parameter of fluid that is in communication with the fluid reservoir as the fluid is communicated from or into the fluid reservoir. An indicator is in communication with the sensor. The indicator is operable to display the physical parameter sensed by the sensor. The apparatus may be used to inject fluid into or withdraw fluid from an implanted gastric band system or for a variety of other uses. Fluid pressure may be adjusted and sensed, and resulting data may be displayed, by a single, integrated instrument.Type: GrantFiled: February 12, 2007Date of Patent: November 29, 2011Assignee: Ethicon Endo-Surgery, Inc.Inventor: Daniel F.

Patent number: 8057492Abstract: Devices and methods for forming a restriction in a patient are disclosed. In one exemplary embodiment, a restriction system is provided including an implantable restriction device, an implantable port in fluid communication with the implantable restriction device, and an implantable pump in fluid communication with the restriction device. In general, the implantable restriction device is adjustable and configured to form a restriction in a patient, and the implantable port is configured to receive fluid from a fluid source external to the patient. The implantable pump is a micro-electro-mechanical systems (MEMS) device effective to create pumping action to move fluid through the pump.Type: GrantFiled: February 12, 2008Date of Patent: November 15, 2011Assignee: Ethicon Endo-Surgery, Inc.Inventors: Mark S.

Patent number: 8016744Abstract: An external pressure sensing system may include an attachment for a syringe. The attachment may comprise a connector positioned between the barrel and the needle of the syringe. A pressure sensor may be in fluid communication with the connector, such that the pressure sensor may sense the pressure of fluid within the connector as the syringe is used to add fluid to or withdraw fluid from an injection port. Where an injection port is a component of an adjustable fluid-based gastric band system, pressure data obtained with the pressure sensor may be indicative of the pressure of fluid within the gastric band. The pressure sensor may communicate pressure data to a display device. A user may adjust the pressure of fluid within the gastric band using the syringe while viewing the display device for pressure-related readings.Type: GrantFiled: March 7, 2006Date of Patent: September 13, 2011Assignee: Ethicon Endo-Surgery, Inc.Inventors: Daniel F.

Patent number: 8016745Abstract: An implantable restriction device is configured to provide a restriction in a patient as a function of the pressure of fluid. The implantable restriction device includes one or more pressure sensors configured to sense pressure of the fluid within the implantable restriction device. Pressure data obtained by the one or more pressure sensors may be communicated to a device located external to the patient, such as a data logger, using telemetry coils or other communicators. The data logger may store the pressure data, and may communicate the pressure data to a remote location via a network such as the Internet. A docking station may be provided to couple the data logger to a network and/or to recharge a cell in the data logger.Type: GrantFiled: April 6, 2006Date of Patent: September 13, 2011Assignee: Ethicon Endo-Surgery, Inc.Inventors: William L.

Publication number: 20110144531Abstract: A pressure sensor may be used to determine the pressure of fluid within an implantable gastric restriction device. An accelerometer may be used to measure movement of the patient in which the gastric restriction device is implanted, such that the movement may be accounted for when evaluating data from the pressure sensing system. For instance, movement data from the accelerometer may be used to identify pressure data that should be ignored. A display may annotate a pressure graph to show changes in pressure associated with patient movement; or may otherwise influence the display of pressure data based on patient movement. The pressure sensor and accelerometer may be incorporated into an adapter placed between a syringe and needle that are used to adjust the fluid pressure in the gastric restriction device. Upon examination of pressure data in relation to movement data, the implantable gastric restriction may be adjusted as needed.Type: ApplicationFiled: December 16, 2009Publication date: June 16, 2011Inventors: Amy L. Marcotte, Daniel F. Dlugos, JR.
