Method and apparatus for performing transesophageal cardiovascular procedures
An apparatus for performing a transesophageal cardiovascular procedure includes an elongated tubular main access device having a first lumen with an open proximal end and a distal side opening, and a second lumen with a rigid outer wall and a collapsible inner wall. The second lumen is adapted to receive an elongated probe or surgical device. The apparatus further includes an inflatable sealing component on the outside of the main access device above and below the side opening, and a first fluid conduit extending along the main access device for inflating the sealing component so that when the main access device is inserted into a patient's esophagus and the sealing component is inflated. The portion of the esophagus opposite the side opening is isolated from the remainder of the esophagus above and below the side opening.
1. A method of performing an intra-thoracic procedure, comprising:
inserting one or more surgical instruments into a patient's esophagus so that the one or more surgical instruments are positioned within the patient's thoracic cavity;
introducing a cutting device into the patient's esophagus so that a distal end of the cutting device is positioned within the patient's thoracic cavity;
forming an opening in an esophageal wall with the cutting device thereby providing access to the patient's intra-thoracic cavity from the esophagus;
establishing a seal around said opening to inhibit fluid leakage between the esophagus and the intra-thoracic cavity; and
performing a surgical procedure in the intra-thoracic cavity using the one or more surgical devices.
2. The method according to claim 1 , further comprising an act of passing a first monitoring device into the patient's esophagus to monitor the procedure.
3. The method according to claim 1 , wherein the act of introducing the cutting device includes an act of passing the cutting device through the one or more surgical instruments so that the distal end of the cutting device is positioned within the patient's thoracic cavity.
4. The method according to claim 1 , further comprising an act closing the opening in the esophageal wall upon conclusion of the intra-thoracic surgical procedure.
5. The method according to claim 4 , wherein the act of closing the opening includes an act of sealing the opening by performing at least one of: applying glue to the opening, suturing the opening, and applying a laser to seal the opening.
6. The method according to claim 1 , wherein the act of establishing the seal around the opening includes an act of inflating at least one inflation member to seal a portion of the esophagus.
7. The method according to claim 6 , wherein the act of establishing the seal includes inflating at least a second inflation member to provide an upper and lower seal in the esophagus.
8. A method for intra-thoracic surgery, comprising:
inserting a first surgical device through a mouth of a patient into an esophagus of the patient;
inserting an incising instrument into the esophagus through the first surgical device;
manipulating the incising instrument from outside the patient to form a perforation in an internal wall of the esophagus opening into a thoracic cavity;
moving a distal end of a second surgical device through said perforation;
performing a surgical operation on the intra-thoracic organ by manipulating the second surgical device;
closing said perforation; and
withdrawing the second surgical device, the incising instrument and the first surgical device from the patient's esophagus.
9. The method according to claim 8 , further comprising an act of establishing a seal around said opening to inhibit fluid leakage between the esophagus and the intra-thoracic cavity.
10. The method according to claim 9 , wherein the act of establishing the seal around said opening includes an act of inflating at least one inflation member to seal a portion of the esophagus.
11. The method according to claim 10 , wherein the act of establishing the seal includes inflating at least a second inflation member to provide an upper and lower seal in the esophagus.
12. The method according to claim 8 , wherein the act of closing the perforation includes an act of sealing the opening by performing at least one of: applying glue to the opening, suturing the opening, and applying a laser to seal the opening.
13. A method for performing a minimally invasive surgical procedure, the method comprising:
inserting a surgical device into a mouth of a patient;
positioning the surgical device within a thoracic cavity of the patient within an esophagus;
isolating a segment of the esophagus using the surgical device; and
generating access to the thoracic cavity, using the surgical device, through the esophagus within the isolated segment.
14. The method according to claim 13 , where in the act of generating includes an act of cutting an opening through the esophagus to generate access to the thoracic cavity.
15. The method according to claim 13 , further comprising an act of passing a second surgical device through the opening.
16. The method according to claim 13 , further comprising an act of performing surgery on an exterior or interior portion of a heart of the patient.
17. The method according to claim 13 , wherein the act of isolating the segment of the esophagus includes an act of inflating at least one inflation member to seal a portion of the esophagus.
18. The method according to claim 17 , wherein the act of isolating the segment of the esophagus includes an act of inflating at least a second inflation member to provide an upper and lower seal in the esophagus.
