Abstract

Surgical devices with integrated, visualization and cauterization are described herein where such devices include an elongate structure having a central lumen and an expandable space-creating structure having at least one expandable leaflet mounted in the vicinity of the distal end and is configured for placement within a mammalian body proximate to a therapeutic target. Also included is a proximal terminal having an actuator mounted in the vicinity of the proximal end and is configured to remain outside of said body and provide an actuation mechanism for actuating the space-creating structure. Additionally, at least one fluid connector and said central lumen is in fluid communication between an interior of the expandable space-creating structure and the at least one fluid connector.

Claims

1. A surgical device comprising:

an elongate structure comprising a distal end, a proximal end, and a central lumen;

an expandable space-creating structure mounted in the vicinity of the distal end and configured for placement within a mammalian body proximate to a therapeutic target, wherein the expandable space-creating structure comprises an optically transparent first leaflet;

a proximal terminal comprising an actuator mounted in the vicinity of the proximal end and configured to remain outside of said body and actuate the space-creating structure to cause the first leaflet to pivot relative to the elongate structure between a closed configuration and an opened configuration; and

an imaging device comprising an optical axis configured to extend through the first leaflet in the closed configuration,

wherein transitioning between the closed configuration and the opened configuration causes the imaging device to pivot so that the optical axis does not extend through the first leaflet, and

wherein the optical axis is substantially parallel to a longitudinal axis of the elongate structure in the closed configuration and wherein transitioning between the closed configuration and the opened configuration causes the optical axis to cross the longitudinal axis.

2. The surgical device of claim 1, wherein the imaging device is pivotably attached to the first leaflet.

3. The surgical device of claim 1, wherein the first leaflet comprises a first electrode and the second leaflet comprises a second electrode, and wherein the first and second electrodes are configured to connect to an energy source and cut or cauterize tissue of the therapeutic target.

4. A surgical device comprising:

an elongate structure comprising a distal end, a proximal end opposite the distal end, and a central lumen extending between the proximal end and the distal end;

an expandable space-creating structure extending from the distal end, comprising a first leaflet and a second leaflet, wherein the first leaflet and the second leaflet are configured to pivot relative to the elongate structure between a closed configuration and an opened configuration; and

an imaging device,

wherein the first leaflet is optically transparent,

wherein the imaging device is positioned between the first leaflet and the second leaflet in the closed configuration and comprises an optical axis that extends through the first leaflet in the closed configuration,

wherein transitioning between the closed configuration and the opened configuration causes the imaging device to pivot so that the optical axis does not extend through the first leaflet, and

wherein the optical axis is substantially parallel to a longitudinal axis of the elongate structure in the closed configuration and wherein transitioning between the closed configuration and the opened configuration causes the optical axis to cross the longitudinal axis.

5. The surgical device of claim 4, wherein the imaging device is pivotably attached to the first leaflet.

6. The surgical device of claim 4, where the second leaflet is optically transparent.

7. The surgical device of claim 4, wherein the first leaflet comprises a first electrode and the second leaflet comprises a second electrode, and wherein the first and second electrodes are configured to connect to an energy source and cut or cauterize tissue.
