A tissue-manipulating system including a tissue-manipulating device having a tissue grasper assembly with at least one grasper arm movably coupled to a shaft to move between a closed configuration and an open configuration. The at least one grasper arm may be pivotably coupled to the shaft, such as via a collar. A tissue-manipulating device controller is coupled to the tissue grasper assembly to move the at least one grasper arm between the closed and open configurations. The tissue grasper assembly is positionable to move a distal tissue wall closer to a proximal tissue wall. The tissue grasper assembly may be deployable (such as by separating from the shaft) to remain in place holding the distal tissue wall and proximal tissue wall in apposition.

The invention provides systems, devices, and methods for the delivery, deployment, and positioning of magnetic compression devices at a desired site so as to improve the accuracy of anastomoses creation between tissues, organs, or the like.

Disclosed are methods, devices and materials for the in situ formation of an implant for treating a nerve. A treatment site on a nerve is positioned within a cavity defined by a form. A transformable media is introduced into the form cavity to surround the treatment site. The media is permitted to undergo a transformation from a first, relatively flowable state to a second, relatively non flowable state to form a protective barrier surrounding the treatment site. A hydrophilic characteristic of the media cooperates with a hydrophobic characteristic of the surface of the cavity to facilitate a rapid release of the implant from the cavity following the transformation. The implant may be a growth inhibiting nerve cap to inhibit neuroma formation following planned or traumatic nerve injury, a growth permissive conduit for facilitating reconnection of a severed nerve, or an anchor for stabilizing a pain management electrode with respect to a nerve. Access to the nerve treatment site may be open surgical or percutaneous.

Tissue anchors comprise a woven filament braid body having an elongated tubular configuration and a foreshortened configuration where proximal and distal ends of the body expand radially into double-walled flange structures while leaving a cylindrical saddle region therebetween. The tissue anchors are deployed through penetrations between adjacent tissue layers, where the flanges engage the outer surfaces of the tissue layers and the saddle region resides within the tissue penetrations.

A device for holding two anatomical structures in apposition. The device includes a first holding member, a second holding member, and a connecting member extending between the first holding member and the second holding member.

A method of percutaneously creating a fistula includes inserting percutaneously a medical instrument to a target location having a first blood vessel and a second blood vessel. A fastener is then deployed via the medical instrument to the target location. The fastener is in a first configuration before the deploying and a second configuration after the deploying. The fastener limits relative movement between the first blood vessel and the second blood vessel when in the second configuration. An anastomosis between the first blood vessel and the second blood vessel is percutaneously produced.

The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to a tissue traction device, e.g., for endoscopic tissue dissection. For example, a tissue traction device may include a first clip comprising opposable jaws. The device may include a traction band having a first end, a second end, a length therebetween and extending along a longitudinal axis. The band may have a first aperture at the first end. A second aperture may be at the second end of the band. A first jaw of the opposable jaws of the first clip may be disposed through the first aperture.

The present disclosure relates generally to medical devices and procedures for placement of a medical device between adjacent tissue structures. In particular, the present disclosure relates to endoscopic systems and methods for preventing or minimizing movement between tissue walls to facilitate placement of a stent therebetween.

Methods and apparatuses for applying tensile force to one or more tissue regions within a body. Illustratively, an implant ball including a spherical side wall is received within a tubular organ, and tensile sutures extend through the implant ball for applying a tensile force to facilitate elongation of the tubular organ.
