Abstract

The current invention describes methods of transesophageal access to the neck and thorax to perform surgical interventions on structures outside the esophagus in both the cervical and the thoracic cavity. It describes a liner device made of a complete or partial tubular structure, or a flat plate, the liner having means to facilitate creation of a side opening, which may include a valve. The liner with its side opening form a port structure inside the esophageal lumen. The port structure allows elongated surgical devices to pass through a perforation across the full thickness of the esophageal wall to outside location, in a controlled way. The elongated surgical devices can be diagnostic scopes, therapeutic scopes, manual elongated surgical devices, robotic arms or the like. After being deployed outside the esophagus, the surgical devices can access structures outside the esophagus, in the neck and thorax in 360 degrees of freedom around the esophageal circumference. These structures can be bony, cartilaginous, spinal, vascular, soft tissue, deep tissues, lymph nodal, cardiac, pulmonary, tracheal, nervous, muscular or diaphragmatic, skin and subcutaneous tissues of the neck, skin and subcutaneous tissues of the anterior chest wall, skin and subcutaneous tissues of the skin of the back, and skin and layers of the breast.

Claims

1. A method of performing transesophageal surgery, wherein the method comprises:

inserting a liner, having a first proximate end, a second distal end and a body portion connecting the first proximate end and the second distal end, through a mouth of a patient;

positioning the first proximate end such that the first proximate end is closer to the mouth of the patient and open to a body lumen, positioning the second distal end so that the second distal end is more distal from the mouth and so that the liner is proximate to tissue of the body lumen, wherein the act of positioning the liner further includes applying at least a portion of a longitudinal wall of the body portion of the liner to the tissue of the body lumen;

inserting a distal portion of a surgical instrument through the mouth of the patient and passing the distal portion of the surgical instrument by the first proximate end of the liner and adjacent to the longitudinal wall of the body portion of the liner; and

extending the distal portion of the surgical instrument through the longitudinal wall of the body portion of the liner and entirely through the tissue of the body lumen,

wherein the liner is placed in the patient'"'"'s esophagus, and the surgical instrument is passed entirely through the liner and the esophagus.

2. The method of claim 1, wherein the liner is a barrier and comprises a complete or partial opening to allow devices to go through an esophageal wall to a target outside the esophageal wall after the liner and the esophageal wall have been penetrated to create an opening.

3. The method of claim 2 wherein the longitudinal wall includes a side opening, and the method further comprises closing the side opening spontaneously upon withdrawal of an instrument.

4. The method of claim 1 wherein the method further comprises performing any one or more of:

tumor excision, tumor biopsy, placement of drugs, placement of tissues, placement of radioactive materials, bronchial biopsy, airway bypass, manipulation of great vessels of the thorax, and pulmonary artery bypass.

5. The method of claim 1 wherein the method further comprises performing a surgical procedure, wherein the procedure to be performed is one or more of disk surgery, vertebral column surgery, spinal cord surgery, nerve root surgery, spinal and paraspinal muscle surgery, vascular surgery, oncologic surgery, laser surgery, delivery of energy to tissue, delivery of tissue or genetic material, delivery of surgical devices, delivery of cardiac pacemaker or diaphragmatic pace maker, and performance of procedures affecting the esophagus itself including fundoplication, and stomach pacemaker implantation.

6. The method of claim 1 wherein the method further comprises performing a surgical procedure, wherein the procedure to be performed is one or more cardiac procedures including mapping, cardiac ablation, valve surgery, closure of septal defects, laser surgery, delivery of energy to the heart and related structures for pacing or to enhance contractility, delivery of drugs or genetic material, and delivery of surgical devices to the heart and related structures.

7. The method of claim 1 wherein the method further comprises performing a surgical procedure, wherein the procedure to be performed is one or more of procedures on the lungs, bronchi, nerves, lymphatics, great vessels of the thorax, bony or cartilaginous structures, diaphragm, phrenic nerve, gastroesophageal junction and on the esophagus itself, including the delivery of an esophageal band for satiety or an intra-esophageal valve for reflux.

8. A method for performing surgery in which at least one liner is placed in a tubular body lumen, including any one or more of the esophagus, the intestine, the genitourinary (GU) tract, the cardiovascular system, the pulmonary system, the canaliculi of the inner ear, and the lymphatic system, the method comprising:

inserting at least one liner having a first proximate end, a second distal end and a body portion connecting the first proximate end and the second distal end, and having at least one side opening, through a respective body opening of a patient;

positioning the first proximate end of the at least one liner such that the first proximate end is closer to an open end of the body lumen,

positioning the second distal end of the least one liner so that the second distal end is more distal from the open end of the body lumen and so that the liner is proximate to tissue of the body lumen,

inserting a distal portion of a surgical instrument through the respective body lumen of the patient and passing the distal portion of the surgical instrument by the first proximate end of at least one liner and adjacent to a longitudinal wall of the body portion of the at least one liner;

extending the distal portion of the surgical instrument through the longitudinal wall of the body portion of the at least one liner and entirely through the tissue of the body lumen;

generating more than one opening entirely through the body lumen through either at least one liner having more than one side opening or more than one liner having at least one opening; and

performing a surgical procedure on a body member that is separate and away from the body lumen.

9. A method as in claim 8 where said opening is sprayed or painted with sealant material to enhance closure of the perforation site.

10. A method as in claim 8 wherein the surgical instrument includes at least one of an operating scope that is a conventional scope, a therapeutic scope with custom made specifications, a robotic scope, and a remotely operated scope.
