Abstract

Surgical systems and methods for administering an ablation treatment and other therapeutic or diagnostic protocols to a patient tissue involve a flexible stabilizer mechanism having an inner recess and an ablation mechanism coupled with the stabilizer mechanism.

Claims (19)

1. A surgical system for administering a lesion forming treatment to a patient tissue, comprising:

a flexible stabilizer defining an inner recess;

a ribcage mechanism comprising a flexible spine with individual ribs extending therefrom defining a ribcage inner recess, the ribcage mechanism disposed within the inner recess of the flexible stabilizer; and

a lesion forming mechanism disposed within the ribcage inner recess,

wherein the lesion forming mechanism is switchable between a bipolar ablation mode and a monopolar ablation mode during a single lesion forming treatment, and

wherein the ribcage inner recess is configured to receive a portion of the patient tissue therein for administration of the lesion forming treatment to the patient tissue received within the ribcage inner recess.

2. The surgical system according to claim 1 , wherein the lesion forming mechanism comprises a member selected from the group consisting of a bipolar radiofrequency energy ablation mechanism, a monopolar radiofrequency energy ablation mechanism, a high voltage pulse mechanism, a microwave energy mechanism, an infrared laser mechanism, a cryo-thermal mechanism, an ultrasound ablation mechanism, a chemical ablation mechanism, and a radiation mechanism.

3. The surgical system according to claim 1 , wherein the flexible stabilizer is configured to deliver suction to a portion of the patient tissue, so as to draw the portion of the patient tissue into the ribcage inner recess, and into proximity with the lesion forming mechanism.

4. The surgical system according to claim 1 , wherein the flexible stabilizer comprises a pocket that channels a vacuum delivered by the stabilizer mechanism.

5. The surgical system according to claim 1 , further comprising a temperature sensor disposed along a central portion of the flexible stabilizer inner recess.

6. The surgical system according to claim 1 , further comprising a cinching mechanism configured to constrict the lesion forming mechanism about the patient tissue.

7. The system according to claim 1 , wherein the flexible stabilizer comprises a pod assembly coupled with the ribcage mechanism.

8. A method for administering a lesion forming treatment to a patient tissue, comprising:

placing a treatment assembly near the tissue of the patient, the treatment assembly comprising a flexible stabilizer defining an inner recess, a ribcage mechanism disposed within the inner recess of the stabilizer mechanism and defining a flexible spine with individual ribs extending therefrom defining a ribcage inner recess, and a lesion forming mechanism disposed within the ribcage inner recess,

delivering a vacuum through the flexible stabilizer and through the ribcage mechanism so as to draw a portion of the patient tissue into the ribcage inner recess; and

administering the lesion forming treatment to the tissue via the lesion forming mechanism to create a lesion in the tissue,

wherein administering the lesion forming treatment comprises switching between bipolar ablation and monopolar ablation during a single treatment.

9. The method according to claim 8 , wherein the lesion forming mechanism comprises a member selected from the group consisting of a bipolar radiofrequency energy ablation mechanism, a monopolar radiofrequency energy ablation mechanism, a high voltage pulse mechanism, a microwave energy mechanism, an infrared laser mechanism, a cryo-thermal mechanism, an ultrasound ablation mechanism, a chemical ablation mechanism, and a radiation mechanism.

10. The method according to claim 8 , wherein the flexible stabilizer comprises a pocket that channels the vacuum delivered through the stabilizer mechanism.
