Various exemplary methods and devices are provided for manipulating and/or anchoring devices and body parts during surgical procedures. In one embodiment, an anchor member is provided for anchoring a device or body part to tissue, such as an internal wall of a body cavity. The device can be, for example, an endoscopic device, an accessory channel coupled to an endoscopic device, or a support member adapted to support or manipulate an organ. The anchor member can include or form an opening through which the device can be inserted. The anchor member or device can thus be manipulated relative to the tissue to control movement of and/or provide support to the device, tools inserted through the device, and/or organs grasped by the device or tools.

Devices and related methods are provided for the controlled delivery of a therapeutic to a targeted location within a body. More particularly, methods and devices are provided for controlling the rate of passage of an orally administered pill through a body, as well as for controlling the delivery of a therapeutic within the pill at a specific location within the body. Various types of devices, generally referred to herein as “catchers,” are provided that can actively catch a pill as it passes through a body. The catcher can hold the pill at a specific location within the body until a predetermined event occurs, such as partial or complete administration of a therapeutic within the pill. The catcher can then release the pill upon command and/or upon the occurrence of the predetermined event to allow the pill to pass out of the body. In other embodiments, various types of pills are provided that can actively engage a catcher and remain engaged with the catcher until a predetermined event occurs.

A method for regulating hormone production comprises placing at least one electrode in a gastrointestinal tract of a patient and recording an electrical signal during a preselected event produced by the gastrointestinal tract. The method further involves the steps of storing the electrical signal, and playing back the electrical signal by activating the electrode during the absence of the preselected event.

A positionable imaging device includes a body defining a first end and a second end. The body is configured to be received within an internal body cavity. An imaging device is located at the first end of the body. A releasable fastener is coupled to the body to removably attach the imaging device to tissue within the internal body cavity. A release mechanism is coupled to the releasable fastener to detach the imaging device from the tissue.

L-cells may be introduced in the gastrointestinal tract. L-cells are used in the digestive process to produce a more efficient and lasting means of regulating feelings of satiation in a patient. Desired metabolic effects may be achieved by manipulating L-cells via delivery sites, frequency of delivery, or type of biological substance delivered.

Methods and devices are provided for manipulating tissue in a body cavity, i.e., in vivo. In general, the methods and devices allow an end effector to engage tissue, be detached from a shaft used to control the end effector to engage the tissue, and then be moved to another location in the body cavity by a separate component, such as an external control unit. In some embodiments the end effector can include one or more deployable hooks that allow the end effector to remain at a surgical site independent of any shafts or external control units. Still further, in other embodiments the end effector can include a transverse bore to allow a second shaft to connect to the end effector to manipulate the tissue. Additional exemplary devices, kits, and methods related to manipulating tissue in vivo are also provided.

A laparoscopic surgical device comprises an elongate shaft defining a longitudinal axis, the shaft comprising a distal end and a proximal end. A plurality of arms project distally from the distal end of the elongate shaft, the arms each comprising a lateral notch. The arms are axially slideable relative the elongate shaft and are medially deflectable. An elongate pin is positioned medially relative the arms. The elongate pin is axially slideable relative the arms between a locked position preventing medial deflection of the arms and an unlocked position allowing medial deflection of the arms. A surgical end effector is selectively attachable in vivo and detachable in vivo to the mating feature of the arms, the surgical end effector comprising jaws that open and close in response to the axial movement of the two arms when attached to the surgical end effector.

An introducer for an internal magnetic camera is provided. The introducer may be arranged to enable the camera to be placed inside of a body cavity through an otomy or incision and then oriented next to the tissue of the body cavity opposite an External Control Unit (“ECU”) outside of the body cavity. The camera may be retained in the introducer by a magnet or a magnetic material, by a selectively engageable retainer, or by covering the camera within a cavity. The camera may be retained in the introducer by a latch. The camera may include a keyed surface that only can align with a matching keyed surface on the retainer in a single orientation. The introducer may include a spring to eject the camera from the introducer when the retainer is disengaged.
