Bronchoscope-compatible catheter provided with electrosurgical device
First Claim
1. A catheter system comprising:
- an electrical adapter including a hollow adapter body having a longitudinally extending channel and an electrical terminal positioned within the longitudinally extending channel, the electrical adapter being configured to be electrically connected to an energy source; and
a catheter having a longitudinal length and being removeably insertable within the electrical adapter, the catheter including an elongated body having a proximal end portion and a distal end portion, the distal end portion defining a first diameter and including an electrosurgical cutting tip, the distal end portion being configured to be inserted into a proximal most end of the longitudinally extending channel and advanced through an entirety of the longitudinally extending channel during an electrosurgical procedure; and
an electrical connector coupled to the proximal end portion of the elongated body, the electrical connector forming an outer periphery of the catheter along a portion of the longitudinal length of the catheter, the electrical connector defining a second diameter larger than the first diameter, the electrical connector configured to be inserted in the channel of the hollow adapter body, wherein the electrical terminal and the electrical connector are configured to be electrically connected to each other when the electrical connector is advanced to an electrical contact position within the channel, and are configured to be electrically isolated from each other when the electrical connector is proximal of the electrical contact position.

Abstract
A catheter system can include an electrical adapter and a catheter. The electrical adapter includes a hollow adapter body having a longitudinally extending channel and an electrical terminal positioned within the channel. The electrical adapter can be configured to connect to an energy source. The catheter can include an elongated body having a proximal end portion and a distal end portion, and an electrical connector coupled to the proximal end portion. The electrical connector forms the outer periphery of the catheter along a portion of the longitudinal length of the catheter. The electrical terminal and the electrical connector contact each other when the electrical connector is advanced through the channel to an electrical contact position in the channel, and are isolated from each other when the electrical connector is proximal of the electrical contact position.

11. A method comprising:
-
inserting a distal end of an inner catheter having a first diameter into a proximal most end of a channel defined by a hollow electrical adapter body; and advancing the distal end of the inner catheter through the channel, through a lumen of an outer catheter that extends distally from a distal end of the channel of the hollow electrical adapter body, and to a first position at which the distal end of the inner catheter exits an opening at a distal end of the lumen of the outer catheter; wherein, when the distal end of the inner catheter is advanced to the first position, an electrical terminal, which is disposed in the channel of the hollow electrical adapter body and electrically connected to an energy source, contacts an electrical connector on a proximal end portion of the inner catheter and having a second diameter larger than the first diameter, and electrically connects the electrical connector to the energy source, wherein when the distal end of the inner catheter is proximal of the first position, the electrical terminal fails to contact the electrical connector and electrically connect the electrical connector to the energy source. - View Dependent Claims (12, 13, 14)
