Title:
ULTRASOUND ASSEMBLY FOR USE WITH A CATHETER
Document Type and Number:
WIPO Patent Application WO2003072165
Kind Code:
A3
Abstract:
An ultrasound catheter (1200) comprises an elongate tubular body (1201). The elongate tubular body has a proximal region (1204) and a distal region (1202) opposite the proximal region. The tubular body defines a central lumen (1251) having a central lumen diameter. The ultrasound catheter further comprises an elongate, hollow inner core (1402) extending through the central lumen. The elongate, hollow inner core has an inner core outer diameter that is less than or equal to the central lumen diameter. The ultrasound catheter further comprises an ultrasound radiating member (1404) positioned within the distal region of the tubular body and between the tubular body and the inner core. The ultrasound catheter further comprises at least two electrical conductors (1206, 1208) extending between the tubular body proximal region and the tubular body distal region. The at least two electrical conductors are positioned between the tubular body and the inner core. The at least two electrical conductors are electrically connected to the ultrasound radiating member. The at least two electrical conductors are wrapped around the inner core a plurality of times in a region between the ultrasound radiating member and the tubular body proximal region.
