Bioresorbable inflatable devices and tunnel incision tool and methods for treating and enlarging a tissue or an organ or a tube or a vessel or a cavity. The device is composed of a hollow expanding pouch made of a resorbable material or a perforated material that can be attached to a filling element. The pouch can be filled with a biocompatible materials, one or more times in few days interval, after the insertion of the device. While filling the pouch every few days the tissue expands and the filling material if it is bioactive start to function. The tunnel incision tool composed of a little blade that emerges from the surface of the tool in order to make shallow incisions in the surrounding tissue therefore enabling easy expansion of the tissue. This device and method can be used for example for: horizontal and vertical bone augmentation in the jaws and the tunnel incision tool is used to make shallow incisions in the periosteum when using the tunnel technique, sinus augmentation when the device is placed beneath the Schneiderian tissue, vessels widening if the pouch become a stent, fixating bone fractures etc.

An apparatus and method for performing needle guided interventions and especially needle guided dilations of tissue to create a therapeutic conduit between two luminal organs or structures. The device is particularly useful for creation of an artificial lumen between two hollow body organs using the working lumen of an endoscope.

The invention provides systems and methods for tissue expansion. A tissue expander may have an implant portion which may be used to expand the tissue. A delivery / drainage system may be also be provided, which may be in fluid communication with a pocket surrounding the tissue expander. Various port configurations may be provided that may provide access to the implant portion and / or the delivery / drainage system. The tissue expander may advantageously help prevent or treat infection, or check the state of the pocket surrounding the tissue expander.

A device for maintaining or achieving soft tissue expansion applicable to any body region already temporarily expanded including: an adhesive element deformable and capable of adapting to the shape of this body region, and which can then itself become mechanically rigid enough to resist tendency of the expanded tissue to recoil or to which a second material can be applied to form a stent adapted to the shape of the body area to provide the necessary structural rigidity to prevent recoil of the expansion and thereby induce its retention of its expanded shape after the stent is removed.

Exemplary embodiments of the present disclosure provide method and apparatus for facilitating stretching of a biological tissue by forming a plurality of micro-slits in the tissue. Each micro-slit can be less than about 2 mm or less than about 1.5 mm long, or even less than about 1 mm, such that small gaps that can heal quickly can be formed when the tissue is stretched. The micro-slits can be formed using a plurality of cutting arrangements or an ablative laser. The micro-slits can be formed in various patterns, including staggered rows, circular or spiral patterns, or random patterns.

Non-fluidized tissue expanders, tissue expander systems, and methods of expanding tissue are disclosed. The tissue expanders, systems, methods of the present invention incorporate an expandable encapsulated body mass implantable within the patient and operative to selectively expand to promote growth of an enlarged area of skin and subcutaneous tissue. Such tissue expansion is accomplished utilizing internal one or more distraction mechanisms disposed within the tissue expanders that are operative to expand by mechanical or electromechanical means. The present invention omits any type of inflatable body requiring the injection of fluids to effectuate expansion of the tissue expander.

A surgical clip includes a pair of opposed arms joined at one end by an integrally formed flexible hinge. A male head element near the free end of one arm is configured to spread tissue when the male head element is urged towards a head mating element near the end of the opposite arm. The clamping side of an arm may include a protruding feature, such as a wedge shape elongated ridge, while the clamping side of the opposite arm includes a corresponding trough or aperture that receives the protruding feature. Clamping surfaces may include non-slip protrusions, such as ribs, ridges, cones or pins. An applicator holding feature, such as a boss, near the hinge prevents the clip from yawing and becoming askew during application. Rectangular alignment features are provided on the distal ends of the arms to maintain clip alignment during application.
