International Classification:

A61M 5/168
A61M 5/145

Abstract:

A system for delivering a medicinal fluid to a patient includes a variable volume pressure delivery chamber, a variable volume medication chamber, an optional medication reservoir, a movable delivery element, a fixed reference volume chamber, a pressure source, and a control sub-system. The variable volume pressure delivery chamber is configured to store pressure controllably. The variable volume medication chamber is fluidically isolated from the pressure delivery chamber and is configured to store medicinal fluid. The movable delivery element is disposed between the medication chamber and the pressure delivery chamber. The pressure source is coupled to the pressure delivery chamber. The control system is configured to selectively cause the pressure source to deliver pressure to the pressure delivery chamber causing the movable delivery element to apply pressure to the medicinal fluid in the medication chamber thereby causing the medicinal fluid to exit the medication chamber at an outlet along the fluid communication path to the patient.

International Classification:

A61B 8/00
A61B 8/08
A61B 1/00

Abstract:

An extension cable is adapted for use in an intravascular ultrasound system. It has a first connector, for connecting to a catheter and a second connector for connecting to a patient interface module. A cable arrangement provides power transmission, data transmission and data signal processing (amplification or regeneration) between the first and second connectors. The extension cable enables sterility to be maintained in a workflow in a time efficient and easy manner as the catheter to extension cable connection may remain in a sterile environment.

G16H 40/67
G16H 30/20

Abstract:

Medical devices, systems and methods are provided. In one embodiments, an intraluminal medical system includes a patient interface module (PIM) configured to selectively communicate with a first intraluminal device or a second intraluminal device different than the first intraluminal device. The first and second intraluminal devices are configured to obtain medical data associated with a body lumen of a patient while positioned within the body lumen. The PIM includes a first connector having a first plurality of pins respectively carrying a plurality of signals. The first intraluminal device includes a second connector configured to engage the first connector and the second intraluminal device includes a third connector configured to engage the first connector. The plurality of signals respectively carried by the first plurality of pins is configured to selectively allow electrical communication between the PIM and the first intraluminal device when the second connector engages the first connector, and between the PIM and the second intraluminal device when the third connector engages the first connector.
