Disclosed herein are intestine pleating attachable structures for use with endoscopes and methods for using said structures. The intestine pleating attachable structures may act in conjunction with a gastrointestinal endoscope and, optionally, a balloon to improve visualization during endoscopic procedures. The intestine pleating attachable structures are coupled to the endoscope shaft, and include at least one flexible appendage to enhance contact between the structure and the intestinal wall. When the endoscope is retracted, the flexible appendage assists in moving the intestinal wall relative to the imaging system. This movement causes the intestine to pleat. Pleating reduces looping, improves efficiency, and results in a less painful endoscopic procedure for the patient. The attachable structures may be used in conjunction with a dome-shaped balloon that is inflated at the distal, imaging end of the endoscope. The balloon is transparent, such that the intestinal wall may still be visualized through the balloon while intestinal matter is prevented from obscuring the image.

Gastrointestinal endoscopy with attachable intestine pleating structures

An endoscopic clip device for closure of a mucosal defect or transmural perforation in a gastrointestinal wall may include a sleeve and a clip disposed at least partially within and coupled to the sleeve. The clip may be configured for reversibly moving between an open configuration for positioning relative to the wall and a closed configuration for closing the defect or perforation. The clip may include a first clip arm configured for engaging the mucosal and submucosal layers of the wall and including a first needle extending to a distal end of the first clip arm and configured for advancing through the mucosal layer and into at least the submucosal layer, and a second clip arm disposed opposite the first clip arm and configured for engaging the mucosal layer. The device may be configured for advancing through an operative channel of an endoscope or overtube having a tortuous shape.

Endoscopic clip devices and related methods for mucosal defect and transmural perforation closure

The endoscopy tool and methods of use disclosed herein are used to move gastrointestinal tissue. The endoscopy tool includes an auxiliary gastrointestinal device, or a catheter, having a proximal region and a distal region. The endoscopy tool includes a non-conductive, polymeric loop coupled to and extending distally from the distal end of the gastrointestinal device. The surfaces of the loop are smooth such that the loop can move intestinal tissue without causing lacerations.

Endoscopy tools and methods of use

Insufflation is currently considered to be a necessary part of an endoscopic procedure. However, it introduces risks and costs that would be beneficial to eliminate. The endoscopic assistance devices and methods disclosed herein facilitate the performance of endoscopic procedures without insufflation. The devices attach directly or indirectly to the distal end portion of the endoscope. One or more resilient, curved bars extend from the attachment point around an internal void space to form a resilient, curved cage that spreads tissue gently during the advance of the endoscope. The resilient, curved bars define the windows of the cage that enable the visualization of the internal anatomy via a lens on the distal face of the endoscope and the passage of treatment devices from the operative channel of the endoscope.

Endoscopic assistance devices and methods of use

A balloon access device for use with an endoscope is disclosed. A transparent balloon attached to the distal end of the endoscope allows a user to both separate collapsed intestinal tissue and visualize the path of the endoscope without administering insufflation gas to the collapsed area of a patient. The attachment of the balloon to the endoscope is achieved by the various embodiments of the balloon access device disclosed herein.

Balloon access device with features for engaging an endoscope

Transparent domes useful for covering at least a lens located on a scope's distal face, taking the form of a single layer membrane affixed to the distal end of the scope, a solid cap attachable to and detachable from the distal end of the scope, or an inflatable and deflatable balloon having an exterior wall for contacting at least the lens at the scope's distal face. Methods for performing diagnostic or diagnostic and therapeutic procedures within bodily cavities including collapsed intestines using transparent domes and scopes.

Disposable and reusable complex shaped see-through endoscope

A material-fastening device and related fastener and methods for use, and more particularly, a device with segments of the fastener capable of being independently attached to different sides of a gap in the material.

Endoscopic stapling device, related staples, and methods for use

A system and method for gaining access to an internal bodily structure, such as the ampullae. The system includes an elongate catheter having a lumen extending there through. An elongate wire including a distal coil is movably extendable from the distal end of the catheter and is configured to engage the inner surface of the bodily structure. Proximal movement of the elongate wire flattens the inner surface of the bodily structure and aligns the passageway thereof with the longitudinal axis of the catheter.

Twist-in spring-skirt-like sphincterotome

Provided is a balloon access device having a cap coupleable to an endoscope and a balloon for sealing with the cap when expanded. The balloon access device allows a physician to both separate collapsed tissue and visualize the path of the endoscope without administering insufflation gas to the collapsed area of a patient.

Balloon access device for endoscope

A material-fastening device and related fastener and methods for use, and more particularly, a device with segments of the fastener capable of being independently exposed from a holding mechanism and independently attached to or placed in proximity to the material.

Dissecting-swatting surgical stapling device and methods of use

A catheter for inserting into a bodily structure. The catheter includes a primary lumen and a secondary lumen having a side hole for engaging under negative pressure with an inter-mural mucosa of the bodily structure. Methods of use of a catheter involving insertion of the catheter into a bodily structure and engaging the catheter under negative pressure with an inter-mural mucosa of the bodily structure.

Method and devices for selective endoscopic retrograde cholangiopancreatography

Apparatus and methods are provided for forming a gastrointestinal tissue fold by engaging tissue at a first tissue contact point, moving the first tissue contact point from a position initially distal to a second tissue contact point to a position proximal of the second contact point to form a tissue fold, and extending an anchor assembly through the tissue fold near the second tissue contact point.

Apparatus and methods for forming gastrointestinal tissue approximations

Disclosed is an introducer apparatus comprising an sleeve fixation mechanism or introducer member, such as a catheter, introducer, or ring-like structure, which is attached to a protective sleeve comprising a thin flexible material such a polymeric film. The sleeve is inverted into the passageway of a second member, such as a catheter, feeding tube, introducer, etc., that is advanced through the passageway of the introducer member and is introduced into a bodily passage of a patient, such as the bile duct, nasal passages, colon, etc. The sleeve everts from the passageway of the second member during its advancement to lay down a friction-reducing surface. The sleeve prevents frictional contact between the second member and delicate or sensitive tissues.
