A syringe pump configured to at least partially surround a syringe loaded into the pump. The syringe pump including a syringe pump housing defining a syringe receptacle shaped and sized to accept loading of the syringe, a plunger driver assembly configured to manipulate a plunger of a syringe loaded into the syringe pump, and a syringe housing including a syringe barrel shield pivotably coupled to the syringe pump housing configured to at least partially enclose a syringe loaded into the syringe pump within the syringe receptacle, and a syringe plunger tray and lid assembly operably coupled to the syringe pump housing and configured to at least partially enclose a portion of the plunger driver assembly.

Systems and methods for syringe handling

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.

A tunneling tool for implanting a medical device into body tissue is described. The tunneling tool comprises a first leg and a second leg. An intermediate portion of the second leg is shaped to nest a medical device therein. A hub connects the first and second distal leg ends together. A sheath providing a lumen extends from the hub to an open end distal of the first and second legs. The first and second legs are manipulatable to separate the hub and the sheath into two portions, a first split portion connected to the first leg and a second split portion connected to the second leg. When a medical device is nested in the tunneling tool, breaking the tunneling tool apart enables the first and second split portions to be removed from body tissue, leaving the implanted medical device behind.

An atherectomy device is disclosed, which is rotationally driven by an electric motor. In some designs, the device includes features unavailable on gas turbine-driven systems, such as the storing in memory of low/medium/high preset rotation speeds for particular models of handle, calculations of the amount of saline left in the IV and associated warnings when it gets sufficiently low, and automatic adjustment of the IV pump rate to a predetermined or calculated level when the rotational speed of the motor is changed. The electric motor has far more rotational inertia than a comparable gas turbine, so the system includes a control mechanism that helps prevent damage from excessive torque being applied to the distal end of the drive shaft. When an obstruction at the distal end is detected, by a drop in the motor rotational speed, the motor is released and is allowed to spin freely as a flywheel. The freely-spinning motor allows the large angular momentum of the system to dissipate rapidly and safely, without excessive torque to the drive shaft.

Rotational atherectomy device with electric motor

The invention provides a rotational atherectomy system, device and method comprising a flexible, elongated, rotatable drive shaft with an abrasive section within a pre-curved section of the drive shaft. The device may further comprise a concentric or eccentric enlarged diameter section that is at least partially covered with abrasive material to comprise the abrasive section. The abrasive section may further comprise an abrasive crown or burr mounted to the drive shaft. The pre-curved drive shaft allows smaller diameter and/or massive abrasive regions to be used while sweeping larger diameters during high-speed rotation. The pre-curved region is substantially straightened for insertion into vasculature and placement adjacent stenosis by insertion of the guide wire. Removal of guide wire proximally from the pre-curved region allows the drive shaft to return to its pre-curved form for ablation. Reinsertion of the guide wire beyond the pre-curved region straightens the drive shaft for ease of removal.

An assembly for exchanging retractor support arms within a retractor support clamp. The assembly includes a main body having a surface defining a cavity extending into the main body from a first end. A support arm having an end portion with a substantially complimentary configuration to the surface defining the cavity is positionable within the cavity. A retaining mechanism is disposed about the main body and in communication with the end portion where the retaining mechanism retains the end portion within the main body.

Surgical support arm docking apparatus

A clamping device which secures a retractor support apparatus to an operating table having a side rail. The clamping device has a first clamping member disposed between a side of the operating table and the side rail. The clamping device also includes a second clamping member disposed between the side rail and the first clamping member. A first securing mechanism operably connects the first and second clamping members such that a force provided by the first securing mechanism causes the first and second clamping members to move in opposing directions and frictionally engage the side of the operating table and the side rail.
