摘要： An implantable medication delivery apparatus (10) including a flow path (32) coupling a medication reservoir (24) to a device outlet port (16) where the flow path (32) includes a regulator means (36) for limiting the magnitude of pressure transferred downstream from the medication reservoir (24). The regulator means (36) is configured to respond to the reservoir pressure exceeding a certain threshold for closing a valve located downstream from the reservoir (24). The valve (36) closure functions to isolate the device outlet port (16) from further reservoir pressure increases which otherwise could induce unintended medication flow from the device outlet port (16).

摘要： A method and system for calibrating and controlling the withdrawal of a fluid, such as blood, from a fluid source, such as a blood vessel, includes a fluid pump (26), a pressure sensor (24), a flow rate sensor, and a microprocessor based flow control subsystem. The flow control subsystem optimizes the flow rate by sensing zero flow rate pressure within the subject, making a plurality of periodic flow path pressure measurements and extrapolating a calibration flow rate curve (110). A control curve (130) is generated by utilizing the zero-flow rate pressure point (100), the slope of the calibration curve (110), and an empirically predetermined pressure offset value (150). The blood pump (26) is then operated at a maximum speed that is limited by the flow control curve (130) to maximize flow without occlusion or collapse of the blood vessel during blood withdrawal. The method and system of the invention is particularly applicable to automated apheresis system.

摘要： Systems and methods for monitoring a bypass device for protecting an intestinal anastomosis are provided. The system includes a pump, one or more fluid inlet lines fluidicly coupled to the pump and to a negative pressure chamber of the bypass device, and one or more sensors configured to measure data indicative of pressure within the negative pressure chamber. A controller operatively coupled to the pump and the one or more sensors may be programmed to actuate the pump to generate a vacuum within the negative pressure chamber to thereby pull intestinal tissue towards the bypass device to anchor the bypass device at a target location upstream of the intestinal anastomosis. The controller further may compare the pressure within the negative pressure chamber with a predetermined pressure range and, if the pressure falls outside the predetermined pressure range, adjust the pump to maintain the vacuum within the predetermined pressure range.

摘要： The present invention provides a system for managing occlusions during phacoemulsification surgery. More specifically, the present invention provides a user of a surgical console an alert when a partial or full occlusion of a surgical tool causes the vacuum pressure to become greater than a predetermined pressure threshold setting and automatically reduces the vacuum pressure when the predetermined pressure threshold setting is exceeded.
