Abstract
An intravenous ultrasound (IVUS) system can include a catheter and a translation mechanism for translating the catheter. Engagement between the catheter and the translation mechanism may be detected, and the translation mechanism can be placed in a connected or disconnected mode, accordingly. When in connected mode, certain IVUS operations may be enabled when compared to disconnected mode, wherein such operations may be disabled. Thus, some embodiments may ensure proper engagement between the catheter and the translation mechanism prior to allowing certain IVUS operations to be carried out.
Claims20
An intravascular ultrasound (IVUS) system, comprising:
- an IVUS catheter comprising:
- a sheath,
- a drive cable extending through the sheath being coupled to an IVUS transducer at a distal end,
- a connector at a proximal end of the IVUS catheter, the connector being coupled to a proximal end of the drive cable, and
- an anchor assembly positioned near a proximal end of the sheath, the anchor assembly being separate from the connector of the IVUS catheter;
- and
- a translation mechanism comprising:
- a catheter interface configured to electrically and mechanically interface with the connector of the IVUS catheter,
- an anchor port separate from the catheter interface and configured to receive the anchor assembly of the IVUS catheter in order to anchor the anchor assembly of the IVUS catheter to the translation mechanism, and
- a sensor positioned proximate the anchor port, the sensor outputting a signal representative of whether or not the anchor assembly of the IVUS catheter is anchored to the anchor port of the translation mechanism to enable a controller to place the translation mechanism in a connected mode if the anchor assembly is anchored to the anchor port or in a disconnected mode if the anchor assembly is not anchored to the anchor port, wherein
- the translation mechanism is configured to translate the catheter interface relative to the anchor port.

An intravascular ultrasound (IVUS) system comprising:
- an anchor sensor;
- an IVUS catheter having
- a sheath,
- a drive cable positioned within the sheath, the drive cable being coupled to an IVUS transducer at a distal end,
- a connector located at a proximal end of the drive cable, the connector being separate from the sheath, and

- a translation mechanism comprising a catheter interface and an anchor port separate from the catheter interface, the translation mechanism being configured to translate the catheter interface relative to the anchor port, and wherein the catheter interface being configured interface with the IVUS catheter via the connector of the IVUS catheter, and wherein the anchor port being configured to engage with the IVUS catheter via the anchor assembly of the IVUS catheter;
- and
- a controller in communication with the anchor sensor and configured to:
- measure a first output from the anchor sensor corresponding to engagement between the anchor assembly of the IVUS catheter and the translation mechanism;
- determine, via the first output, if the anchor assembly of the IVUS catheter is anchored to the anchor port of the translation mechanism;
- place the translation mechanism in a connected mode if the anchor assembly is anchored to the anchor port or in a disconnected mode if the anchor assembly is not anchored to the anchor port;
- and
- provide a signal to a user alerting the user if the translation mechanism is in the disconnected mode.
