Abstract:
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.
Abstract:
An implantable restriction device (10) includes a belt (30) and a balloon (32) secured to the belt for engagement with tissue when the implantable restriction device is positioned about the stomach. A spacer (14) is associated with the belt for maintaining the restriction device in a spaced relation with a staple line employed during gastric reduction surgery.
Abstract:
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.
Abstract:
Various methods and devices are provided for accessing a body cavity. In one embodiment, a surgical access device is provided and includes an elongate member having a proximal support member configured to rest against an external tissue surface, a flexible elongate central portion extending distally from the proximal support member and configured to extend through tissue, and an inflatable distal portion coupled to a distal end of the central portion. The distal portion is movable between an initial configuration, in which the distal portion is configured to be passed through an incision in tissue, and an inflated configuration in which the distal portion is expanded such that the central portion forms a working channel through the tissue for access to a body cavity. The distal portion can include an opening such that gas delivered to the distal portion can flow through the opening to insufflate a body cavity.
Abstract:
A system and method to be used in ultrasonic or other types of lithotripsy of a stone in a ureter, the system including a catheter having a stone probe tip capable of transmitting stone reducing energy. The catheter can include an expandable funnel section adjacent to the probe tip, such that expansion of the expandable funnel section can dislodge a stone by pushing back on the ureter wall expanding it slightly. The funnel section also being capable of pooling some urine in the ureter to be used as an ultrasonic transmission media. The stone probe can be connected to a source of energy capable of driving the probe tip to deliver energy to break apart the stone.

Abstract:
A diagnostic device (10) for pathologies of tubular anatomical structures comprises a tubular elongated structure (12, 28) developing between a proximal end and a distal end and is suitable to be inserted in the tubular anatomical structure, means (22, 32) for locally dilating the walls of the tubular anatomical structure that are associated with the distal end of said elongated structure, said means for locally dilating being movable between a closed position for introducing the device and at least one open position for viewing and evaluating the pathology, and control means being associated with the proximal end of the elongated structure, said control means being operatively connected to said means for locally dilating, in order to move them between the closed position and the open position, and vice versa.
