Improved methods and devices for performing an endoscopic surgery are provided. Systems are taught for operatively treating gastrointestinal disorders endoscopically in a stable, yet dynamic operative environment, and in a minimally-invasive manner. Such systems include, for example, an endoscopic surgical suite. The surgical suite can have a reversibly-expandable retractor that expands to provide a stable, operative environment within a subject. The expansion can be asymmetric around a stabilizer subsystem to maximize space for a tool and an endoscope to each be maneuvered independently to visualize a target tissue and treat the target tissue from outside the patient in a minimally invasive manner.

Endoluminal device with retractor system

The present disclosure describes an intervertebral implant having a laterovertically-expanding shell operable for a reversible expansion from a collapsed state into an expanded state, the laterovertically-expanding shell having one or more connectors, and a pair of lateral extension elements that function to laterally expand the footprint of the implant within an intervertebral disc space.

Asymmetrically expandable cage

An expansion member for distributing graft material through a cage and into an intervertebral space is provided. The expansion member has a central beam with an entry port in fluid communication with an exit port for distribution of the graft material. The central beam is inserted into a cage having a reversible collapse from an expanded state into a collapsed state, the expanded state forming a graft distribution window. The expanded state, for example, can be configured to open the graft distribution window which at least substantially closes upon the reversible collapse.

Distributing graft material from an expandable cage

An intervertebral scaffolding system is provided having a laterovertically-expanding frame operable for a reversible collapse from an expanded state into a collapsed state, the laterovertically-expanding frame having a stabilizer that slidably engages with the distal region of the laterovertically-expanding frame and is configured for retaining the laterovertically-expanding frame from a lateral movement that exceeds the expanded state. The expanded state, for example, can be configured to have an open graft distribution window that at least substantially closes upon the reversible collapse.

Methods of stabilizing an intervertebral scaffolding system

Improved methods and devices for performing an endoscopic surgery including a system for performing minimally invasive procedures including a flexible catheter having a first lumen, a first flexible tube positioned in the first lumen, and a second flexible tube positioned in the first lumen. The first lumen defines a first space configured and dimensioned to receive an endoscope. The first flexible tube and second flexible tube are fixed at a proximal portion and configured to float within the first lumen of the catheter. First and second flexible guides are slidably positioned within the first and second flexible tubes and dimensioned to receive a first instrument for axial movement therein, the first and second flexible guides movable to an angled position with respect to a longitudinal axis. A working space expanding system positioned at a distal portion of the flexible catheter, the working space expanding system movable from a non-expanded insertion position to an expanded position forming an expanded region to expand the working space within the body lumen.

Tissue retractor for minimally invasive surgery

An intervertebral scaffolding system is provided having an expandable frame operable for a reversible collapse from an expanded state into a collapsed state, the expandable frame having a stabilizer, one or more tensioners, or a combination of the stabilizer with one or more tensioners. The stabilizer slidably engages with the distal region of the expandable frame and both the stabilizer and the one or more tensioners are configured for retaining the expandable frame from a lateral movement that exceeds the expanded state, and the stabilizer can include a locking element that engages with the expansion member to lock the expansion member to the stabilizer when the expansion member is fully inserted into the frame. The expanded state, for example, can be configured to have an open graft distribution window that at least substantially closes upon the reversible collapse.

Methods of stabilizing an inter vertebral scaffolding

The present disclosure describes an intervertebral implant having a laterovertically-expanding shell operable for a reversible expansion from a collapsed state into an expanded state, the laterovertically-expanding shell having one or more connectors, and a pair of lateral extension elements that function to laterally expand the footprint of the implant within an intervertebal disc space.

Improved methods and devices for performing an endoscopic surgery are provided. Systems are taught for operatively treating gastrointestinal disorders endoscopically in a stable, yet dynamic operative environment, and in a minimally invasive manner. Such systems include, for example, an endoscopic surgical suite. The surgical suite can have a reversibly expandable retractor that expands to provide a stable, operative environment within a subject. The expansion can be selectively asymmetric to maximize space for a tool and an endoscope to visualize a target tissue and treat the target tissue from outside the patient in a minimally invasive manner.

Devices, systems, and methods for minimally invasive surgery in a body lumen

The devices and methods generally relate to treatment of occluded body lumens. In particular, the present devices and method relate to removal of the occluding material from the blood vessels as well as other body lumens.

Atherectomy devices and methods

An intervertebral scaffolding system is provided having a laterovertically-expanding frame operable for a reversible collapse from an expanded state into a collapsed state, the laterovertically-expanding frame having a stabilizer, one or more tensioners, or a combination of the stabilizer with one or more tensioners. The stabilizer slidably engages with the distal region of the laterovertically-expanding frame and both the stabilizer and the one or more tensioners are configured for retaining the laterovertically-expanding frame from a lateral movement that exceeds the expanded state, and the stabilizer can include a locking element that engages with the expansion member to lock the expansion member to the stabilizer when the expansion member is fully inserted into the frame. The expanded state, for example, can be configured to have an open graft distribution window that at least substantially closes upon the reversible collapse.

Dual coil ablation systems are provided. Methods of using the systems to ablate tissue are also provided. The dual coil ablation systems can include a first guide needle and a second guide needle, and the methods can include securing the tissue and guiding the dual coil ablation system into the tissue for the ablation, the securing and the guiding facilitated by the first guide needle and the second guide needle. The dual coil ablation systems can also include a phase-offset between the coils to achieve a significant and surprising enhancement to the energy density provided by the systems, and the uniformity of ablation provided by the methods.
