摘要:
A surgical or diagnostic camera system is disclosed that has a disposable cap-like device that is structured for removal of adhesions while under direct visualization with the camera. The adhesion removal device may have an electrode on the tip that can be activated to enhance separation of tissues and may be configured to securely snap on to the housing of the camera system.

Methods and devices create an intestinal braking effect, are non-invasive or minimally invasive, and may be reversible. These methods and devices may be accomplished via stabilized implantable systems and ingestible pills. In one aspect, a method of inducing satiety includes implanting an implant within a lumen of a gastrointestinal tract and retaining a portion of chyme that flows by the implant within a body of the implant. The method further involves re-releasing the retained chyme from the implant into the gastrointestinal tract at a predetermined rate slower than a rate caused by natural peristalsis.

A medical device comprises a handle comprises an actuator. A shaft extends distally from the handle. A first shaft segment extends proximally from the handle and has a proximal end and a distal end. A second shaft segment has a proximal end and a distal end and is pivotably supported with respect to the distal end of the first shaft segment at a position offset from a longitudinal axis of the shaft in a first offset direction. A third shaft segment has a proximal end and a distal end and is pivotably supported with respect to the distal end of the second shaft segment at a position offset from the longitudinal axis of the shaft in a second offset direction different from the first offset direction. A first member extends through at least a portion of the first shaft segment and is operatively associated with the actuator. A second member extends through at least a portion of the second shaft segment. The second member has a proximal end pivotably supported with respect to the distal end of the first member and a distal end pivotably supported with respect to the third shaft segment. The actuator is operative to provide substantially simultaneous compound articulation of the second and third shaft segments.

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.
摘要:
A staple having a crown, a deformable leg extending from the crown, and a spring extending from the crown configured to compress tissue between the spring and the deformable member. Owing to the flexibility of the spring, the staple can accommodate a wide range of tissue thicknesses while still compressing the tissue captured therein. As a result, a single staple design can be used in a wide variety of surgical procedures thereby reducing the amount of staple designs that must be provided to the surgeon. In at least one embodiment, the staple includes a crushable member. This crushable member can include a plastically deformable first portion and an elastically deformable second portion. The present invention can also include, in various embodiments, a crown, a first deformable member extending from the crown, and means for compressing the tissue against the first deformable member.
摘要:
A device for inducing satiety including an elongated device for insertion through a natural orifice and into a stomach of the patient. The distal end of the device includes a means for occupying space between the submucosal and muscularis layers adjacent a pyloric sphincter. The means has a collapsed state for delivery to a target site and an expanded state for implantation thereof.
摘要:
Methods and devices are provided for performing minimally invasive surgical procedures. In one embodiment, a surgical device is provided that includes an elongate shaft having a distal portion configured to be movable between a first configuration in which the distal portion of the shaft is substantially straight or linear and a second configuration in which the distal portion of the shaft is bent at a compound angle. The shaft's distal portion can be configured to be articulated in a wide range of compound angles and can be configured to be selectively locked in a fixed position anywhere within that range.
摘要:
Methods and devices create an intestinal braking effect, are non-invasive or minimally invasive, and may be reversible. These methods and devices are accomplished via stabilized implantable systems, and ingestible pills. In one embodiment, the implantable system comprises a device delivering a therapeutic substance to a target location within the gastrointestinal tract of a patient in order to initiate an intestinal braking effect which would promote sensations of satiety and stimulate excess weight loss for the patient.
摘要:
A method for inducing satiety using the steps of inserting an elongated device into a patient through a natural orifice and into a stomach of the patient, placing a distal end of the elongated device adjacent a treatment site within the stomach, and delivering at least one space occupying member through the elongated device adjacent the treatment site and implanting the at least one space occupying member between the submucosal and muscularis layers at the target site.
