An infusion pump, including a housing, a user interface, a motor and a set of drive components, and a controller. The housing enables selective stacked attachment with other infusion pumps. The housing includes a top portion with a handle integrated into an outer surface that partially defines a generally U-shaped retaining feature. The housing also includes a bottom portion with a generally U-shaped projection that is contoured to selectively mate with the retaining feature of another infusion pump. The user interface provides a front side to the housing that receives commands regarding infusion pump operation. The motor and set of drive components are at least partially located within the housing and mechanically direct infusion of infusate. The controller is located within the housing and that controls operation of the motor and the set of drive components.

Housing arrangements for infusion pumps

Infusion pump interfaces providing simple and intuitive user experiences. A controller display subsystem for implementing infusion pump interfaces includes a processor, a memory, display logic, keypad I/O, and screen I/O. Display logic can command the processor via the memory to implement desirable displays on screen I/O.

User experience for infusion pumps

A medical device can be localized by providing at least three non-colinear localization elements (e.g., electrodes) thereon. Once placed in a non-ionizing localization field, three adjacent localization elements, at least one of which will typically be a spot electrode, may be selected, and the non-ionizing localization field may be used to measure their locations. A cylinder is defined to fit the measured locations of the selected localization elements. The cylinder is rotationally oriented using the measured location of a spot electrode. Location and rotational attitude information may be used to construct a three-dimensional representation of the medical device within the localization field. The electrodes may be provided on the medical device or on a sheath into which the medical device is inserted. The invention also provides systems and methods for identifying and calibrating deflection planes where the medical device and/or sheath are deflectable.

Devices and methods for catheter localization

An infusion pump includes a pumping mechanism having at least one sensor and a pump motor and a pump control subsystem configured to control operation of the pumping mechanism, the pump control subsystem including a processor, a memory, and a startup module configured to drive the pump motor at a first rate, receive input from the at least one sensor, and drive the pump motor at a second rate based on the input received from the at least one sensor. Startup algorithms command an infusion pump to reach a targeted delivery rate or steady state in minimal time without requiring priming of the pump line or otherwise engaging in known methods of pump startup analysis.

Pump startup algorithms and related systems and methods

An apparatus for imparting a tensile force to deflect a distal portion of a catheter while maintaining its exterior dimensions may include a handle grip including a cross-section of generally predetermined exterior dimensions, and a longitudinal axis. A flexible elongate member may include proximal and distal end portions, with the proximal end portion being coupled to the handle grip. An adjustment knob may include a cross-section of generally predetermined exterior dimensions, and is rotatably coupled to the handle grip around the longitudinal axis. An elongate deflection member may be operably coupled to the adjustment knob and to the distal end portion of the elongate member. Rotation of the adjustment knob may impart a tensile force to the deflection member thereby causing the distal end portion of the elongate member to deflect from a prior configuration while maintaining the generally predetermined exterior dimensions of the handle grip and the adjustment knob.

A medication safety device and method can include an infusion pump and a drug library in communication with the infusion pump. The drug library can have upper hard and soft limits and lower hard and soft limits associated with at least one drug. A graphical user interface can display a bar chart showing upper and lower soft limit bars for the at least one drug. The upper and lower soft limit bars can be grabbed and dragged on the graphical user interface in touch-screen fashion to new positions associated with new upper and lower soft limits. The graphical user interface and associated hardware and software can be configurable to responsively re-analyze data and compare a particular infusion to the new upper and lower soft limits.

A method of manufacturing a flexible tubular body for a medical device includes extruding an inner layer from a thermoplastic polymer, pulling it over a mandrel, and tightening it down. If wire lumens were not formed in the inner layer when extruded, polymer spaghetti tubes with wire lumens are laid along the outer surface of the inner layer. Deflection wires are fed into the wire lumens. A wire braid is placed over the inner layer (and spaghetti tubes, if present) and tightened down. The components are encased in an outer polymer layer and a heat shrinkable tube. Pressurized fluid is injected into each wire lumen to maintain the internal diameter thereof greater than the diameter of the deflection wire received therein. Heat is applied to the assembled components, causing the layers to laminate. Once the laminated body has cooled, the heat-shrinkable tube is removed.
