A flexible direct vision fiberoptical viewing cable is placed within a urinary catheter with its tip located at a distal end of the catheter such that the surfaces of the distal end of both the viewing cable and the catheter are aligned so as to fit together in such a way as to form a composite smoothly curved surface to facilitate negotiating obstructions. The cable is maintained in this position within the catheter with the surfaces that comprise the tip of the instrument, maintained in alignment. The urethra is then viewed therethrough during all or part of the insertion procedure for observing and identifying obstructions that may be present and thereafter the fiberoptic cable is withdrawn while allowing the catheter to remain in place within the urethra.Another form of instrument includes a working sheath and an obturator. A method is also described for facilitating endoscopic examination and surgical procedures through the sheath.

A method is disclosed for introducing a spinal disc implant into an intervertebral space of a subject. The subject is placed in a lateral position, and the anterior face of the spinal disc intervertebral space is accessed, between the L5 and S1 vertebrae, from an anterior and lateral retroperitoneal approach. An operative corridor to the anterior face of the spinal disc space is established by introducing a retractor instrument anterolaterally to the spinal disc space between the anterior superior iliac spine and the anterior inferior iliac spine. The damaged spinal disc contents are removed from the intervertebral space through the operative corridor, and the implant is advanced into the intervertebral space at an oblique angle and pivoted to position the implant substantially laterally within the intervertebral space. Elongated retractor and insertion instruments, as well as a modified disc implant, are also disclosed for carrying out the method.

A system and method are disclosed for planning a percutaneous procedure and for guiding an instrument to engage a target within a patient's body. A patient 3-dimensional image data set is provided, within which a user selects a skin entry point and a target point.

An invertebral implant for replacing a damage invertebral disk within the spinal column can include a generally flat body having opposing surfaces and peripheral wall or surface that extends between the opposing surface. Protruding outwardly from the peripheral wall can be a shelf-like flange that has a reduced thickness compared to the thickness of the main body of the implant. The flange provides an object or structure that the surgeon can grasp with forceps during insertion between adjacent vertebrae. Because the protruding nature and reduced thickness of the flange, both the flange and the forceps placed thereon can fit within or adjacent to the intervertebral space between the adjacent vertebrae without interfering with orientation or placement of the main body between the vertebrae. Hence, the flange may simplify the surgical insertion procedure.

A method verifying the position of a surgically inserted orthopedic insert. A preoperative three dimensional image data set of the surgical site is generated, showing the bone into which the insert is to be inserted. During the insertion procedure, a series of intraoperative two-dimensional fluoroscope images are generated, each at a known pose relative to the bone, showing the insert during or after insertion into the bone. The 3-D position of the insert is determined in an intraoperative three dimensional image data set reconstructed from the series of intraoperative 2-D fluoroscope images. The reconstructed intraoperative 3-D image data set is registered with the preoperative three dimensional image data set, such as by comparison of imaged anatomical features. Once this registration is achieved, the determined 3-D position of the insert is used to implant a virtual image of the insert into the preoperative three dimensional image data set.
