Abstract:

A clip device for hemostasis includes an introducing tube (outer sheath) insertable into a body cavity. An operating wire is slidably inserted into an inner sheath, which in turn is separately advanceable and retractable within the outer sheath (introducing tube). The operating wire has a distal end portion and a retainer attached to the distal end portion of the operating wire. The clip device further includes a clip having a proximal end portion and at least three arm portions extending from the proximal end portion and provided with a tendency to open. A first retainer is attached to the distal end of the clip and is matingly received by a second retainer provided on the operating wire. A clip sliding ring is provided for closing the arm portions of the clip. Methods for delivering the clip and for causing hemostasis are also provided.

US Classification:

604509, 604510, 604104, 604 9601, 604264

Abstract:

A device for directing a wire guide into a bodily passageway such as a branch of the biliary tree or other difficult to access bodily passageway. The device includes a member, such as an inflatable balloon or a self-expanding basket, for obstructing a first passage. Once the balloon is inflated, or the basket expanded, the wire guide can be reliably directed or deflected into a preferred adjacent passageway in order to cannulate the preferred adjacent passageway. A procedure for cannulating a preferred passageway by obstructing a passageway in the natural flow-path of a wire guide is also provided.

International Classification:

A61B 17/08

US Classification:

606153, 604264

Abstract:

A medical system for approximating the esophageal sacs in an infant afflicted with esophageal atresia. The medical device includes an esophageal catheter and a gastric catheter. The distal end of the esophageal catheter, which includes a magnetic tip, is passed through the esophagus to the upper esophageal sac. The distal end of the gastric catheter, which also includes a magnetic tip, is passed through a gastrostomy and into the lower esophageal sac. The magnetic forces created by both magnets results in approximation of the esophageal sacs. Pressure-induced necrosis establishes a passageway between the esophageal sacs. A stent or stent-graft can be deployed within the established passageway to prevent re-synopsis of the esophagus.

Abstract:

An endoscopic cutting device is disclosed. The device comprises an inner catheter including an inner wall having an opening formed therethrough. The inner wall further has a cutting blade moveably disposed thereon and biasingly extends through the opening. The inner wall has a receiving member disposed thereon and is configured to cooperatively receive the cutting blade. The device further comprises an outer catheter including an outer wall moveably disposed about the inner catheter. The outer wall has an aperture formed therethrough. The aperture is configured to moveably align with the opening of the inner wall for allowing the cutting blade to biasingly extend through the opening and biasingly engage the cutting blade with the receiving member to cut.

Abstract:

Methods of packaging a medical device to orient at least a portion of the medical device and a medical device packaging assembly are provided. A method includes providing an elongate holder having a lumen extending through at least a portion of the holder and providing the medical device including an elongate shaft where the shaft includes a first cross-sectional area having a rotational orientation and a second cross-sectional area having a second rotational orientation. The method further includes aligning the first and second areas so that the first and second rotational orientations are aligned along a longitudinal region of the shaft and inserting at least a portion of the medical device into the lumen of the holder Radial rotation of the first area with respect to the second area is substantially prevented.

US Classification:

600102, 604174

Abstract:

A medical device for allowing a physician to unhand a scope or other instruments while maintaining control of the scope or other instruments during a medical procedure. The medical device includes at least one docks and a harness for attaching the dock to the physician's body. The harness can be adjustable, or sized to fit a specific physician. During a procedure, a physician outfitted with the medical device can place a scope and/or other instrument in the dock(s). Once the scope and/or other instrument is placed in the dock(s), the physicians hands are free to perform other procedures, while the physician continually controls the relative position of the scope with respect to the physician or the patient.

International Classification:

A61M 29/00

US Classification:

606192, 623 2365

Abstract:

A delivery system and method of use thereof for introducing a bundled intragastric bag into a gastric lumen are described. The delivery system includes a pushing mechanism movable between an unexpanded and expanded configuration. The pushing mechanism in its expanded configuration pushes each of the bundles of the bag into the gastric lumen. A suture strand is periodically pulled during the procedure to help create doughnut-shaped bundles. Another suture strand extends between a proximal button and distal button of the deployed assembly to maintain the doughnut-shaped bundle structure.
