Abstract: 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.

Abstract: A compact medical infusion pump includes a base unit and a compact pump mechanism coupled to the base unit. The compact pump mechanism also includes a carriage member shaped to support a medical syringe, is movable in a first linear direction relative to the base unit, and is fixed to a first guide rod arm. The mechanism further includes a plunger driver shaped to selectively engage a plunger portion of the medical syringe, is moveable in a second linear direction opposite the first linear direction, and is fixed to a second guide rod arm. The mechanism also includes a rotatable drive member that is centrally located with respect to the base unit and is driven by a drive train assembly. The rotatable drive member engages both the first guide rod arm and the second guide rod arm to translate the carriage member and the plunger driver in opposite directions.

Abstract: 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.

Abstract: The present invention is a handle for controlling the deflection of a distal end of a catheter body. The catheter body includes first and second deflection wires that extend through the catheter body from the distal end of the catheter body. The handle comprises a slide base, an adjustment knob, a first slide and a second slide. The slide base includes a first end, a second end, and a slide compartment longitudinally extending through at least a portion of the slide base. The adjustment knob is rotateably connected to the first end of the slide base and includes a hole extending through the knob, wherein at least a portion of an inner diameter of the hole includes an internal right thread and an internal left thread. The first slide is located in the slide compartment, is adapted to be coupled to the first deflection wire, and includes an external right thread. The second slide is located in the slide compartment, is adapted to be coupled to the second deflection wire, and includes an external left thread.
