Catheter system
First Claim
1. A catheter system comprising:
- a catheter having an elongate flexible shaft, the shaft having an outer surface defining an outer transverse cross-sectional dimension; and
a handle having a connector for connecting the catheter to the handle, the connector being generally tubular having a sidewall, an open front end, an open rear end and a channel extending longitudinally within the connector from the front end to the rear end thereof, the connector channel has an inner transverse cross-sectional dimension that receives the catheter shaft therein, at least a segment of the channel being configured such that the inner transverse cross-sectional dimension thereof is greater than the outer transverse cross-sectional dimension of the catheter shaft, said connector further having a port extending through the sidewall into fluid communication with said at least a segment of the channel, the port exposing the catheter shaft within said segment of the channel and permitting adhesive to enter the channel via the port and flow circumferentially about the outer surface of the catheter shaft within said segment of the channel, wherein, over a first segment of the connector channel, an inner surface of the sidewall is tapered such that the inner transverse cross-sectional dimension of the connector channel increases as the connector channel extends towards the front end.

Abstract
In a catheter system and method for assembly thereof, one end of a catheter shaft is inserted into a connector for a handle, with the connector being generally tubular and having a channel extending longitudinally therethrough. At least a lengthwise segment of the channel is sized in transverse cross-section greater than an outer cross-section of the catheter shaft. The catheter shaft is inserted into the channel of the connector such that the catheter shaft is spaced from the connector within the lengthwise segment of the channel. Adhesive is directed through a port in the sidewall of the connector into the lengthwise segment of the channel to flow circumferentially about the catheter shaft within the channel. The adhesive is allowed to cure and the connector (with the catheter adhered thereto) is retained on the handle.
