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

A system for compressing body tissue including a clip having first and second tissue contacting surfaces. The clip is movable from a closed position to an open position wherein the clip receives tissue between the first and second tissue contacting surfaces to compress tissue between the first and second tissue contacting surfaces. A clip deployment device has a first clip engagement member and a second clip engagement member engageable with the clip, the first and second clip engagement members movable between first and second positions to controllably move the clip from the closed position to the open position.

Surgical clip and deployment system

A medical device for debridement can include a handpiece, a shaft extending through the handpiece and distally therefrom, a drive to manipulate the cutter, a handle slidably coupled to the elongate housing and extending distally therefrom, and at least one locking mechanism configured to fix the handle to the handpiece. The handle can be configurable to multiple positions along the length of the handpiece, and can be removed therefrom.

Adjustable locking handle design for debriders

A colpotomy device for performing a hysterectomy is provided. The device includes a flexible drive tube having a proximal end and a distal end and bendable therebetween. The device also has a rotatable cutting implement at the distal end of the flexible drive tube at a specified offset from a bendable longitudinal axis of the flexible drive tube. Furthermore, the device includes couplings located within the flexible drive tube and rotatable about the bendable longitudinal axis of the flexible drive tube. The couplings can be in a series that includes inter-coupling joints and transmits a rotational force between the proximal and distal ends of the flexible drive tube through a variable angle between the couplings. The variable angle can correspond to bending of the drive tube in order to drive rotation of the cutting implement at the specified offset about the axis of the flexible drive tube.

Flexible drive tube for laparoscopic device

A medical device for performing a hysterectomy is provided. The medical device has a tissue incision assembly that includes a first cup nested within a second cup. The tissue incision assembly also includes a spacer assembly between the first cup and the second cup in order to maintain a spacing between the first and second cups. The tissue incision assembly also has a cutting implement that has a portion extending between, and movable with respect to, the first and second cups. The cutting implement can provide a circular cut guided via the spacing between the first and second cups.

Colpotomy cup assembly

A knob locking assembly for a laparoscopic medical device is provided. The knob locking assembly includes a lock configured to engage the knob locking assembly with a drive tube housing of the laparoscopic medical device in extended and retracted positions where the knob locking assembly rotates but does not translate with respect to the drive tube housing when engaged. The knob locking assembly also has a biasing member that provides a biasing force for biasing the lock in each of the extended and retracted positions to lock out longitudinal translation of the rotatable drive assembly when the knob locking assembly is engaged with the drive tube. In addition, the knob locking assembly includes an actuator to counter the biasing force for disengaging the lock to permit longitudinal translation of the rotatable drive assembly via the knob locking assembly when disengaged.

Proximal locking mechanism for colpotomy device

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

Improved methods and devices for performing an endoscopic surgery including a system for performing minimally invasive procedures including a flexible catheter having a working space expanding system positioned at a distal portion, 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. A tissue retractor having an inner member positioned within an outer member has a plurality of closed loops at a distal portion forming a petal-like structure. The loops are positioned in a collapsed position within the outer member and are movable to an expanded position when exposed from the outer member.

System for a minimally-invasive, operative gastrointestinal treatment

A system for controlling operation of a radiofrequency treatment device to apply radiofrequency energy to tissue to treat tissue to create lesions without ablating the tissue. The system includes a first treatment device having a plurality of electrodes. The electrodes are maintained in axial alignment and fixed radial spacing in retracted and extended positions. The device includes a basket having a plurality of arms. The arms are maintained in a fixed radial spacing in the collapsed position of the basket.

Systems and methods for treating tissue with radiofrequency energy

Devices used to deliver a substance within a patient's body are disclosed. The devices may include a microcatheter configured to deliver the substance to a targeted site. The microcatheter may include an expandable member to temporarily restrict blood flow in a vessel, a flow restriction member to restrict flow of material out a distal end of the microcatheter, and a port disposed proximal of the expandable member.

Microcatheter occlusion embolization catheter

Implantable drug delivery devices are provided to have a deployment shape for implantation in the body and a retention shape for retention in the body. The device may have one or more elongated drug reservoirs containing a drug, and the drug reservoir may be formed from a deformable material. In one case, a first filament is attached to the first end of the drug reservoir and second filament is attached to the second end of the drug reservoir, wherein a fastener is positioned about the first and second filaments to permit shortening and prevent lengthening of the filaments with reference to the ends of the drug reservoir, as a means for transforming the device from the implantation shape to the retention shape.

Drug delivery devices for deployment in genitourinary sites

The present invention provides gastrointestinal devices for limiting transfer and contact of material across luminal walls along a segment of the gastrointestinal tract (e.g., at the duodenum and/or upper jejunum). Devices of the invention include a gastrointestinal sleeve, an anchor, and a flange for attachment to a luminal wall proximal to the pyloric orifice. The invention also provides methods of use associated with such gastrointestinal devices, including methods for delivery, removal, and treatment of metabolic disorders, such as type 2 diabetes, non-alcoholic steatohepatitis, non-alcoholic fatty liver disease, obesity, and related comorbidities thereof by implanting gastrointestinal devices.
