Abstract

An introducer catheter device comprising a handle and an elongate shaft coupled to the handle and extending therefrom. The shaft defines a lumen therethrough, a longitudinal axis, and a first aperture in connection with the lumen. The shaft includes a movable deployment element configured for deploying an ancillary device from the first aperture at an angle relative to the longitudinal axis.

First claim

We claim:

1. An introducer catheter device comprising:
a handle; and
an elongate shaft coupled to the handle and extending therefrom, the shaft defining a lumen therethrough and a longitudinal axis, the shaft defining a first aperture in connection with the lumen, and comprising a movable deployment element configured for deploying an ancillary device from the first aperture at an angle relative to the longitudinal axis;
wherein the shaft comprises a weeping balloon encapsulating a shaft portion comprising a digital camera.

2. The introducer catheter device of claim 1 , wherein the deployment element comprises a slidable member and a rail member, the slidable member configured to slidably move along the rail member such that as the slidable member advances in a longitudinal direction either proximally or distally relative to the rail member, the slidable member articulates to a predetermined angle.

3. The introducer catheter device of claim 2 , wherein the predetermined angle of the slidable member ranges from about 1 degree to about 180 degrees.

4. The introducer catheter device of claim 2 , wherein the deployment element when in a fully deployed state, is positioned at an angle ranging from about 60 degrees to about 80 degrees relative to a longitudinal axis defined by the shaft.

5. The introducer catheter device of claim 2 , wherein the deployment element is configured to actuate into a fully deployed state when the slidable member is advanced a predetermined distance in the longitudinal direction proximal to the rail member.

6. The introducer catheter device of claim 5 , wherein the predetermined distance ranges from about 5 mm to about 10 mm.

7. The introducer catheter device of claim 2 , wherein the slidable member comprises a distal face defining an opening, the opening being sized to engage with a portion of the ancillary device received therein.

8. The introducer catheter device of claim 1 , wherein the deployment element comprises a deflectable shaft fully disposed within a cavity defined within the shaft when in a first configuration, and at least partially deflectable in a radially outward direction relative to the cavity in a second configuration.

9. The introducer catheter device of claim 8 , further comprising an actuator coupled to the handle, and a cable coupled to and extending from the actuator to the deflectable shaft, wherein the actuator is configured to apply tension to the cable to deflect the deflectable shaft into the second configuration.

10. The introducer catheter device of claim 8 , wherein the deflectable shaft deflects to a curve angle that ranges from about 45 degrees to about 180 degrees, or from about 30 degrees to about 270 degrees.

11. A system comprising:
the introducer catheter device of claim 1 ; and
a needle catheter device that includes a proximal end, a distal end, and an elongate shaft, the distal end comprising a needle tip, and the shaft of the needle catheter device configured for being received within the lumen of the introducer catheter device, the needle catheter device being extendable through the first aperture.

12. The introducer catheter device of claim 1 , wherein the shaft defines a second aperture in connection with the lumen, the second aperture comprising an elongate slot formed longitudinally along the shaft.
