Patent number: 9517305Abstract: Systems and methods for intelligently delivering fluid to a targeted tissue. The systems and methods may include directing a pump to distribute fluid to a targeted tissue and receiving one or more signals from an intracorporeal sensing system, where the one or more signals correspond to one or more sensed feedback parameters at the targeted tissue. The systems and methods may also include determining whether the one or more sensed feedback parameters are within an acceptable range. If the one or more sensed feedback parameters are not within the acceptable range, the systems and methods may include determining an adjusted velocity for the plunger necessary to adjust the pressure of the fluid in the pump so that the one or more sensed feedback parameters move within the acceptable range and directing the pump to distribute the fluid at the adjusted velocity.Type: GrantFiled: March 15, 2013Date of Patent: December 13, 2016Assignee: BAYER HEALTHCARE LLCInventors: Martin J.
