Publication number: 20080125702Abstract: The present invention relates to an implantable infusion pump having a refillable infusate reservoir in fluid communication with a delivery site via a flow path. This flow path includes a flow resistance. The infusion pump includes a sensing device(s), positioned relative to the flow path, to provide data regarding a flow rate along the flow path. The infusion pump effects a division of a total flow period into at least a plurality of unit dose periods, each unit dose period effecting delivery of a unit dose of infusate. The cumulative effect of delivering the total number of unit dose periods is the delivery of a desired dose over the total flow period. The present invention permits a reservoir pressure to vary over any portion of total flow period but effects a constant-pressure state over each unit dose cycle.Type: ApplicationFiled: January 29, 2008Publication date: May 29, 2008Applicant: ADVANCED NEUROMODULATION SYSTEMS, INC.Inventors: Brian Blischak, John H. Erickson, Terry Daglow, Sandra Marie Hooper, Bruce David Wigness

Publication number: 20040065615Abstract: An implantable infusion pump to deliver stored infusate to a desired fluid delivery site. The pump includes a collapsible fluid chamber. The pump can include a multi-stage filtration system to filter micro-emboli as well as larger particles that are inadvertently introduced into the pump system. An external member can receive the pump and provide a medium to include additional, interactive components, e.g., a bolus port, as well as provide a versatile suture structure to enable the pump to be properly secured within an implantation site. To improve volumetric efficiency, the pump can further incorporate an outlet flow passage within a movable wall of the fluid chamber.Type: ApplicationFiled: October 7, 2003Publication date: April 8, 2004Applicant: Advanced Neuromodulation Systems, Inc.Inventors: Sandra Marie Hooper, Bruce David Wigness, Brian Russell Blischak
