Devices, methods, and systems provide a surgical access device comprising an internal retractor device integrated with or coupled to a body wall or wound retractor. The wound retractor retracts an opening in a body wall into a body cavity, while the internal retractor permits a user to control the positions of internal structures within the body cavity, thereby permitting a user to define a surgical field. Embodiments of the internal retractor are adjustable.

Surgical access device comprising internal retractor

A tissue retractor comprising an outer ring, an inner ring, and a flexible, metal sheath extending therebetween is described. Embodiments of the inner ring comprise a flat or wedge-shaped conformation useful for insertion between muscle layers. Other embodiments of the inner ring include variable diameter inner rings, where the diameter can be adjusted as required and optionally locked into place, and reshapeable inner rings that permit a user to conform the inner ring to the anatomy of the patient when placing the inner ring.

Multifunctional surgical access system

The invention primarily is directed to a medical tubing adapted for insertion into a body tissue or cavity and method of manufacturing different variations of the tubing along a length of the tubing. The tubing comprises a plurality of individual, discrete, generally ring-shaped elements arranged in series and fused or bonded together forming a continuous tubular structure. The ring-shaped elements may include a combination of flexible and rigid ring-shaped elements assembled along different portions or sections of the tubular structure. In another aspect of the invention, the medical tubing may further comprise a secondary lumen and a pull wire to control the tubular structure. In another aspect of the invention, the ring-shaped elements may vary in diameter and/or composition in different portions or sections of the tubular structure.

Medical tubing having variable characteristics and method of making same

An incrementally adjustable wound retractor (), having a first ring () with a diameter greater than the desired diameter of the wound incision, a flexible second ring (), having a lumen and a diameter greater than the desired diameter of the wound incision, and a flexible sleeve (), disposed in a generally cylindrical form between the first and second rings (), where the second ring may be rolled over itself to provide a sleeve with a radical retraction force sufficient to stretch the incision to the desired diameter.

Wound retractor

Medical tubing having variable characteristcs and method of making same

A tissue retractor comprising an outer ring, an inner ring, and a flexible, metal sheath extending therebetween is described. Embodiments of the outer ring comprise an outer ring rotatable around an annular axis thereof, thereby rolling the sheath therearound when retracting an incision or opening in a body wall. Embodiments of the sheath comprise a plurality of linked loops, a plurality of loops joined by a wire extending through adjacent loops, a braided wire, and a plurality of chains. Also described are kits comprising outer rings, inner rings, and sheaths, some or all of varying dimensions, which may be selected and assembled by the user for their intended use. Some or all of the kit components may be resterilized for reuse.

A surgical access system comprises a wound retractor comprising an outer anchor, an inner anchor, and a flexible, tubular sheath extending therebetween. Embodiments of the outer anchor comprise an outer ring rotatable around an annular axis thereof, thereby rolling the sheath therearound when retracting an incision or opening in a body wall. The sheath comprises a plurality of fibers or strands that improve the abrasion and puncture resistance thereof. Consequently, the surgical access system is useful in procedures in which damage to the sheath is likely, for example, orthopedic hip replacement, and spinal procedures. In some embodiments, the sheath tapers from the outer ring to the inner ring.

Multi-functional surgical access system

A method for manufacturing a kink-resistant tube having drainage holes is provided. A wire is coated with plastic material and wound around a mandrel forming a plurality of windings. The wound coated wire is heated until the plastic coating material melts and bonds the wire windings to form a wire-reinforced sheath having wire-containing sections and non-wire containing sections. Alternatively, a coated or non-coated wire is wound around a mandrel together with separate polymer filament material and then heated. A filament having an elongated cross-section may be employed with the major axis of the elongated cross-section substantially parallel to the longitudinal axis of the sheath. At least one non-wire containing section is identified by passing light through at least one wall of the wire-reinforced sheath. Image capture and analysis via an optical system and microprocessor automatically identify regions to target a drill for forming holes in the non-wire containing sections.

Method of making tubing have drainage holes

An efficient and cost-effective method of manufacturing a kink-resistant tube, wherein a coated wire is wound around a mandrel while simultaneously being heated to melt the coating, is provided.
