Abstract
Medical devices that include a medical tool, a handle and a flexible cable bundle passing through the handle. The handles and cable routing therethrough are adapted to reduce noise within the cable.
Claims22
An ultrasound imaging catheter, comprising:
- an elongate shaft sized and configured to be advanced within a patient;
- a handle adjacent the elongate shaft sized and positioned to remain outside of the patient, the handle including an outer surface configured to be gripped by a user;
- a distal tip including an ultrasound transducer;
- an elongate cable bundle in communication with the ultrasound transducer, the elongate cable bundle passing through the elongate shaft and extending into the handle,
- wherein the elongate cable bundle passes through a ferrite bead that is secured within the handle, wherein the ferrite bead is configured to provide between 90 ohms and 102 ohms of impedance at a frequency in the range 5 megahertz (MHz) to 10 MHz, wherein the relationship between the impedance (X), frequency (f), and capacitance (C) is based on
- X
- =
- 1
- 2
-
- π
-
- fC
- ,
- and wherein a shield layer of the cable bundle is removed from the elongate cable bundle within the handle at a location such that the shield layer does not pass through the ferrite bead that is secured within the handle.

An ultrasound imaging catheter, comprising:
- an elongate shaft sized and configured to be advanced within a patient;
- a handle adjacent the elongate shaft sized and positioned to remain outside of the patient, the handle including an outer surface configured to be gripped by a user;
- a distal tip including an ultrasound transducer;
- an elongate cable bundle in communication with the ultrasound transducer, the elongate cable bundle passing proximally through the elongate shaft and extending into the handle comprising an electrical noise suppression member is configured to provide between 90 ohms and 102 ohms of impedance at a frequency in the range 5 megahertz (MHz) to 10 MHz, wherein the relationship between the impedance (X), frequency (f), and capacitance (C) is based on X=wherein the elongate cable bundle is folded upon itself in a folded region within the handle, and wherein a shield layer of the cable is removed from the cable bundle within the handle before the folded region such that the shield layer is not disposed in the folded region.
