摘要:
The invention relates to a method for discriminating cells of a cellular structure, notably of a cellular tissue, comprising the steps consisting in determining (12) a frequency spectrum of the impedance of the cellular structure; defining (22) at least one model of the impedance of the cellular structure including a constant phase element (30); determining (44) the impedance of the constant phase element (30) which optimizes the correlation of each model of the impedance of the cellular structure with the spectrum; and deducing (66), from the impedance of the constant phase element (30) or from the impedances of the constant phase elements (30), an item of information on the cells of the cellular structure. The invention also relates to a system for implementing the method for discriminating cells of a cellular structure.

The invention relates to a medical device (12) comprising an electrical measurement circuit (16), in which are connected at least two sensors (22) with variable impedance according to a physical magnitude detected, an electric energy source (18) for powering the electric measurement circuit (16), an antenna (18) for emitting an electromagnetic field in accordance with the impedance of the electrical measurement circuit (16), each of the sensors (22) being associated with a switch (24) so as to short-circuit the sensor (22) in said measurement circuit (16), the medical device (12) also including a system (26) for controlling the switches (24) in order consecutively to control the opening or the closing of the switches (24), according to predetermined configurations. In particular, the medical device (12) can be used on the human body or implanted in the human body.
摘要:
Connection transmitter for connecting a guidewire to a connector assembly (14), comprising: - a casing (16) surrounding at least partially the connector assembly, - a longitudinal connecting element (18) extending inside the casing along a longitudinal axis (X). The connecting element is translatable along a transversal axis, and receives the guidewire. The connector assembly comprises at least one connection blade extending along the transversal axis, and the connecting element comprises at least one transversal cavity (26) for receiving the guidewire, and cooperates with the connection blade. The connection transmitter presents: - a non-connecting configuration, in which the transversal cavity (26) and the connection blade are transversely disengaged, - a connecting configuration, in which the transversal cavity (26) and the connection blade are transversely cooperating by engagement. The connecting configuration enables to connect the guidewire with the at least connection blade.
摘要:
Embodiments described relate to a medical device including an invasive probe that, when inserted into a duct (e.g. vasculature) of an animal (e.g., a human or non-human animal, including a human or non-human mammal), may be used to aid in diagnosing and/or treating a lesion of the duct (e.g. a growth or deposit within vasculature that fully or partially blocks the vasculature). The invasive probe may have one or more sensors to sense characteristics of the lesion, including by detecting one or more characteristics of tissues and/or biological materials of the lesion.
