  • Publication number: 20240009387
    Abstract: 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.

  • Patent number: 8628551
    Abstract: 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.

  • Publication number: 20070260124
    Abstract: 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.

  • Patent number: 5792046
    Abstract: A surgical support structure joint includes a shaft having an axis, a first support member rotatably supported about the axis of the shaft and a camming member coupled to the first support member. The camming member is movable between a first clamped position and a second unclamped position. In the first clamped position, the camming member applies greater force to the first support member than in the second unclamped position to prevent rotation of the first support member in the first clamped position and to permit rotation of the first support member in the second unclamped position.
