Benefits of technology

This invention is a surgical device that combines a needle tip with a imaging device and a cryosurgical probe for precise tissue manipulation. The device has a rigid structure with a central lumen and lateral fenestration for fluid delivery and dissection. The needle tip can be connected to an imaging display for real-time visualization. This invention allows for improved precision and safety in surgical procedures.

Problems solved by technology

However, proper positioning of the cooling probe relative to the tissue may be difficult to achieve due to a number of factors such as limited space, lack of visual contact, anatomical obstructions, etc.

Embodiment Construction

[0056]FIG. 1 is an illustration of the central embodiment of surgical imaging probe 1 configured for accessing a distal surgical site within a patient by advancement between anatomical structures by atraumatic blunt dissection using image guidance for the purpose of performing a cryosurgical step. Surgical imaging probe 1 comprises probe shaft 2, non-coring optically transparent needle tip 3, probe handle 8, electrical lead 4, electrical connector 5 fluid tube 6 and fluid connector 7. Probe shaft 2 is between approximately 5 and 20 centimeters long, and between approximately 2.5 and 3.5 millimeters in diameter. Probe shaft 2 has a central lumen between approximately 2.3 and 3.3 millimeters in diameter. Probe shaft 2 may be fabricated from a stainless steel hypodermic tube, or may be fabricated from another metal used in surgical instruments such as titanium. Probe shaft 2 is substantially rigid and is capable of transmitting lateral, longitudinal, and torsional forces along its leng...

Abstract

A direct vision cryosurgical and methods of use are described herein where the device may generally comprise an elongated rigid structure with a distal end, a proximal end, and a central lumen. The distal end may comprise a non-coring optically transparent needle tip with at least one lateral fenestration in communication with the central lumen. The distal end may also house at least one imaging device configured for distal imaging. A proximal end of the device may comprise a handle with a means for connecting the imaging device(s) to an imaging display(s), and a means for accessing bodily tissue in the vicinity of the distal end with a cryo-ablation probe through the central lumen and the lateral fenestration(s) for diagnostic or therapeutic purposes.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to U.S. Prov. Pat. App. 61 / 858,104 filed Jul. 24, 2013, which is incorporated herein by reference in its entirety.FIELD OF THE INVENTION[0002]The present invention relates to cryosurgical probes and their methods of use. More particularly, the present invention relates to cryosurgical probes which are configured to be advanced into a body lumen while providing for direct visualization.BACKGROUND OF THE INVENTION[0003]Accessing and treating regions within a body lumen such as the nasal cavities are often performed by utilizing a probe which is cooled via a chilled fluid, a cryo-fluid such as Nitrous Oxide, or through some other cooling mechanism. The cooled tip can be placed into contact against the tissue region to be treated. However, proper positioning of the cooling probe relative to the tissue may be difficult to achieve due to a number of factors such as limited space, lack of visual contact, anatomic...
