Abstract
A medical device, such as an electrophysiology catheter, has an elongate body including a wall. A reinforcing layer is encapsulated in the wall. The reinforcing layer includes one or more reinforcing fibers having glass cores and polymer claddings. In embodiments, the one or more reinforcing fibers are non-magnetically-susceptible and non-electrically-conductive, facilitating use of the medical device in connection with procedures such as magnetic resonance imaging (“MRI”).
Claims6
A shaft for a medical device configured for use in a human vasculature, the shaft comprising:
- an elongate structure comprising:
- a tubular inner layer;
- a braided reinforcing layer around an outer surface of the tubular inner layer, the reinforcing layer comprising a plurality of reinforcing fibers, wherein each reinforcing fiber of the plurality of reinforcing fibers comprises a glass core surrounded by a polymer cladding;
- and
- an outer layer bonded to the inner layer such that the reinforcing layer is encapsulated between a material of the outer layer and a material of the inner layer.
