Abstract: A system for controllably administering fluid to a patient. The system including a syringe, a pump, and a user input. The syringe including a plunger with a first mechanical interface and a syringe body for holding fluids. The pump includes a second mechanical interface which interfaces with the plunger via the first mechanical interface to advance the plunger relative to the body of said syringe to controllably administer fluid to the patient. The user input connects to the pump and allows the user to operate the pump to start and stop the translation of the plunger. The syringe includes a mechanical connector configured such that the syringe is attachable to and detachable from the pump and wherein when the syringe is detached from the pump, the plunger of the syringe may be operated manually by the user.

Abstract: Method and system for controllably administering and/or withdrawing fluid from a patient. In one embodiment, the system may include an infusion needle, a pump adapted to be operably coupled to the infusion needle for creating fluid flow through the infusion needle, and a hands-free switch for activating and/or deactivating the pump.

Abstract: Method and system for controllably administering and/or withdrawing fluid from a patient. In one embodiment, the system may include a needle assembly, an ultrasound imager, a fluid supply storage unit, a waste storage unit, a fluid pump, and a foot pedal assembly. A syringe may serve as the fluid supply storage unit and the waste storage unit. The pump may include a bi-directional motor and a gear coupled to the motor. The gear may be engageable with a rack on the syringe plunger to drive the plunger either for fluid aspiration or infusion. Depression of one portion of the foot pedal assembly causes the motor to drive the gear in one direction, and depression of another portion of the foot pedal assembly causes the motor to drive the gear the other direction. The system may include a control device to keep pressure in the fluid path from exceeding a limit.

Abstract: A composite guidewire comprising a proximal wire segment having a proximal end, a distal end and a longitudinal axis extending therebetween, the distal end being formed with a first flat planar bonding face which extends parallel to the longitudinal axis, the proximal wire segment having a first elasticity; a distal wire segment having a proximal end, a distal end and a longitudinal axis extending therebetween, the proximal end being formed with a second flat planar bonding face which extends parallel to the longitudinal axis, the distal wire segment having a second elasticity; wherein the first and second flat planar bonding faces of the proximal wire segment are formed complementary to one another; and further wherein the proximal and distal wire segments are joined together by bonding the first flat planar bonding face to the second flat planar bonding face in an overlapping manner and a method for forming a composite guidewire.

Abstract: A temperature-controlled actuator has a housing (12) with a proximal end and a moveable distal portion. A core-wire (16) extends along the housing, with its distal section anchored to the distal portion of the housing. The core-wire's distal section has an austenite state and a martensite state. The distal section moves the distal portion by transitioning between the austenite and martensite states in response to a temperature change along a thermometric section (22, 24) of the core-wire. A proximal section in mechanical communication with the core-wire's distal section transmits tension, provided by a tensioning element (20), to the distal section. The tensioning element, which is coupled to the proximal section of the core-wire, constantly applies a tensioning force to the core-wire.
