摘要:
Medical systems, devices and methods are provided for engaging tissue, e.g. for clipping tissue, closing a perforation or performing hemostasis. Generally, the medical system including a housing, first and second jaws rotatable relative to the housing, first and second links attached to both the jaws and the housing, and a driver. The housing, first and second jaws, and first and second links form a linkage mechanism that allows the jaws to engage tissue and be left in vivo.

Medical systems, devices and methods are provided for engaging tissue, e.g. for clipping tissue, closing a perforation or performing hemostasis. Generally, the medical system including a housing, first and second jaws rotatable relative to the housing, a driver, and an elongate drive wire. The elongate drive wire may be disconnected from the driver, first and second jaws, and the housing, which are left in vivo engaged with the tissue.

Medical systems, devices and methods are disclosed for suturing a perforation in tissue, that may be employed endoscopically and/or laparoscopically, and that offer simple, reliable and controllable placement of suture around a perforation for complete closure thereof. One embodiment of the medical system generally includes an endoscope, an endcap, a needle, a suture, and first and second grip systems configured for relative translation to selectively pass the needle between the first and second grip systems.

Multi-luminal endoscopic systems for sterilely delivering deployable devices. The system comprises an outer catheter comprising a distal portion and a wall that encloses an outer lumen; an inner catheter movably disposed within the outer lumen and having an inner lumen; a balloon-tipped catheter movably disposed within the inner lumen and having a distal portion and a proximal portion, wherein the distal portion of the balloon-tipped catheter comprises a balloon; a deployable device within the outer lumen; an invertible sleeve within the outer lumen with a first section attached to the distal portion of the outer catheter and a second section attached to a push mechanism that is proximal to the deployable device; and wherein the balloon is expandable to contact the invertible sleeve to provide a seal to prevent bodily fluids from entering the outer lumen.

Medical devices, systems and methods are disclosed that serve to guide one or more medical devices through a port formed in bodily tissue to access a bodily cavity. One embodiment of the medical device includes a connection member, a rail, and a carrier. The connection member is structured for attachment to the port. The rail is attached to the connection member, and has a first portion extending distally through the port opening, and a second portion extending at an angle relative to the first portion. The carrier is structured to selectively connect to the first portion of the rail, and is slidable along the first and second portions of the rail.

A flexible mesh ablation device for ablating tissue in a body lumen. The flexible mesh ablation device includes a flexible mesh with at least one conductor on an exterior surface of the flexible mesh. When the flexible mesh is compressed axially it expands radially to contact the inner surface of the body lumen and conform to the shape of the body lumen. Power is applied to the conductor ablating tissue proximate the conductor.

Devices and methods are provided for accessing a bodily opening that, among other things, are safe, reliable and repeatable. One embodiment of a device for anchoring to tissue includes an elongated tube and a magnet. The elongated tube has a proximal end opposite a distal end, and defines a central axis. The magnet is attached to the distal end of the elongated tube and has a magnetic field attractive to the magnetic material in the tissue. The magnet has an annular shape defining an aperture through which the elongated tube extends.
