Control handle with device advancing mechanism
First Claim
1. A catheter comprising:
- a catheter body;
a tip section distal the catheter body;
a device extending through at least the catheter body;
a control handle proximal the catheter body, the control handle having an advancing mechanism comprising a threaded member having a threaded outer circumference defining a channel, an adjustment member surrounding the threaded member, and a guided member between the threaded member and the adjustment member, wherein the device is connected to the guided member, and wherein the adjustment member is configured to guide the guided member to move within the channel to wind and unwind the device in the channel to thereby advance and retract the device along the catheter body.

Abstract
A catheter having an internal advancing mechanism that can advance stiffening wires or other devices, has a catheter with a catheter body, a tip section distal the catheter body, a device extending through at least the catheter body, and a control handle proximal the catheter body, where the control handle has an advancing mechanism with a threaded member, an adjustment member, and a guided member to which the device is connected, and the advancing mechanism is configured to advance and retract the device along the catheter body as controlled by a user. Each of the threaded member and the adjustment member has a generally cylindrical configuration. The threaded member has an outer surface configured with a helical guide channel. The adjustment member is configured to guide the guided member to move within the helical guide channel to advance and retract the device. The adjustment member can be rotatable over the threaded member by the user to control advancement and retraction of the device. The device may be a stiffener wire, a needle or any other device suitable for advancement and retraction in a catheter.

18. A catheter comprising:
-
a catheter body having an outer wall, proximal and distal ends and at least one lumen extending therethrough; a tip section comprising flexible tubing having proximal and distal ends and at least one off-axis lumen, and optionally at least one additional lumen, therethrough, the proximal end of the tip section being fixedly attached to the distal end of the catheter body; a control handle comprising a threaded member having a threaded outer circumference defining a channel, an adjustment member mounted on the threaded member and a guided member situated therebetween; and a device connected to the guided member and extending distally therefrom through the control handle, the catheter body and the tip section, wherein the adjustment member is configured for rotation relative to the threaded member to thereby guide the guided member to move within the channel to wind and unwind the device in the channel to thereby advance and retract the device. - View Dependent Claims (19, 20, 21, 22)
