OPEN LOOP POLYPECTOMY SYSTEM

Embodiments of this invention relate to endoscopic and laparoscopic surgical instruments. More specifically, embodiments of this invention relate to an open loop polypectomy system including a means for securely closing the loop. In some embodiments, the open loop polypectomy system comprises a snare wire and a capture mechanism wherein, when the snare wire is advanced, the snare wire extends from a distal portion of the open loop polypectomy system along a path passing through the capture mechanism. After the snare wire has advanced through the plane of the capture mechanism, retraction of the capture mechanism secures the snare wire, creating a formed loop around a target tissue. Retraction of at least one of the snare wire and capture mechanism contracts the formed loop, resecting the target tissue.

An apparatus and method of manufacture includes a helical wire coil and a core wire. The core wire has a first wire portion and a second wire portion. The first wire portion of the core wire extends through the helical wire coil. The second wire portion of the core wire is intertwined with the first helical wire coil to fixedly secure the core wire relative to the first helical wire coil. The core wire is formed from a first material that is non-extensible. The core wire is fixedly secured relative to a distal portion of the helical wire coil such that the core wire inhibits longitudinal elongation of the helical wire coil along a longitudinal coil axis.

Multi-shield spinal access system

An access device for accessing an intervertebral disc having an outer shield comprising an access shield with a larger diameter (˜16-30 mm) that reaches from the skin down to the facet line, with an inner shield having a second smaller diameter (˜5-12 mm) extending past the access shield and reaches down to the disc level. This combines the benefits of the direct visual microsurgical/mini open approaches and the percutaneous, “ultra-MIS” techniques.
