Abstract
A catheter for an ultrasound system can a marker disposed on the hub. The marker is optically or magnetically readable and, when read, identifies the catheter. A drive unit can include an optical or magnetic marker reader. Alternatively or additionally, a catheter may include an active memory arrangement that can be read by an appropriate reader on the drive unit.
Claims19
An intravascular imaging device, comprising:
- a catheter having a proximal end region;
- a hub coupled to the proximal end region, the hub being configured to be secured to a control module that includes a drive unit and a processor;
- an imaging core disposed within the catheter, the imaging core including a rotatable drive shaft and an imaging transducer coupled to a distal end of the rotatable drive shaft;
- wherein the rotatable drive shaft is configured to be coupled to the drive unit;
- a reader coupled to the processor;
- a marker coupled to the hub, the marker being configured to identify the catheter when read by the reader;
- and
- a housing disposed on and projecting from the hub in a direction that is parallel to a longitudinal axis of the catheter, the housing being disposed about the marker and being configured to axially align the marker with the reader by engaging and nesting with a projection disposed about the reader.

A catheter for an ultrasound system, the catheter comprising:
- a catheter sheath defining a lumen and a longitudinal axis;
- a hub coupled to the catheter sheath, the hub including a flanged region with a housing projecting from the flanged region in a direction parallel to the longitudinal axis of the catheter sheath;
- a drive unit configured to be attached to the hub;
- an imaging core slidable disposed within the catheter sheath, the imaging core include an ultrasound transducer, a drive shaft, and a conductor coupled to the ultrasound transducer and extending toward the drive unit;
- an active memory member disposed on the flanged region of the hub and within the housing projecting from the flanged region, wherein the active memory member is configured for transferring information that identifies the catheter;
- and
- wherein the housing projecting from the flanged region is configured to axially align with, nest with, and engage a corresponding projection disposed on the drive unit.
