Abstract: An orthopedic bone cutter for cutting bone and tissue is described. The orthopedic bone cutter comprises a cutting shell and a cutting insert that resides within an opening that extends through the apex region of the shell. A pin and slot mechanism positioned within the shell interior provides for independent axial and rotational movement of the insert within the shell. The shell comprises a partially hemispherical structure having a plurality outwardly extending and spaced apart shell cutting teeth. The insert comprises an annular sidewall that meets an end wall having a plurality of outwardly extending and spaced apart insert teeth. With the insert at a retracted position within the shell, the bone cutter is rotated in a first direction to cause the shell cutting teeth to cut, for example, an acetabular roof and labrum. Then, rotation of the shell in a second opposite direction causes the shell to stop cutting, but provides for the insert to extend outwardly to cut the acetabular floor and fossa.

Abstract: A method of displaying pain or stimulation experienced by a patient includes providing a graphical user interface configured to receive an input from a user and display a visual output to the user. A first map and a second map are concurrently displayed via the graphical user interface. The first map and the second map are each a pain map or a stimulation map. The pain map represents a body area of the patient experiencing pain. The stimulation map represents a body area of the patient experiencing electrical stimulation. A virtual control mechanism is displayed via the graphical user interface. Through the graphical user interface, an engagement of the virtual control mechanism is detected. In response to the engagement of the virtual control mechanism, respective visual emphases of the first map and the second map are simultaneously adjusted.

Abstract: A capacitor having at least two side-by-side anodes with a cathode current collector disposed between the anodes and housed inside a casing is described. Cathode active material is supported on the opposed major faces of the current collector and the current collector/cathode active material subassembly is housed in a first separator envelope. The first separator envelope is positioned between the side-by-side anodes and this electrode assembly is then contained in a second separator envelope. The two anodes can be connected in parallel inside or outside casing, or they can be unconnected to each other. There is also cathode active material supported on inner surfaces of the casing in a face-to-face alignment with an adjacent one of the anodes. That way, the second separator envelope also prevents direct physical contact between the anode pellets and the cathode active material supported on the casing sidewalls.

Abstract: A multilayer helical wave filter having a primary resonance at a selected RF diagnostic or therapeutic frequency or frequency range, includes an elongated conductor forming at least a portion of an implantable medical lead. The elongated conductor includes a first helically wound segment having at least one planar surface, a first end and a second end, which forms a first inductive component, and a second helically wound segment having at least one planar surface, a first end and a second end, which forms a second inductive element. The first and second helically wound segments are wound in the same longitudinal direction and share a common longitudinal axis. Planar surfaces of the helically wound segments face one another, and a dielectric material is disposed between the facing planar surfaces of the helically wound segments and between adjacent coils of the helically wound segments, thereby forming a capacitance.

Abstract: A wet tantalum capacitor of a dual anode design is described. The anodes are housed in their own casing compartments, which are separated from each other by an intermediate partition. Preferably, the casing comprises two clamshell-shaped members that house respective anodes. The clamshells face each other, but are prevented from direct contact by the intermediate partition. The clamshells are welded to opposite sides of the partition to hermetically seal the casing. Prior to sealing, however, cathode active material is contacted to inner face walls of the clamshells and the opposite sides of the partition. The cathode active material is aligned in a face-to-face relationship with major surfaces of the anodes. Preferably, a polymeric restraining device prevents the anode from contacting the case. The hermetically sealed casing is filled with electrolyte thru a port. The fill port is hermetically sealed to complete the capacitor.

Abstract: Tantalum powders produced using a tantalum fiber precursor are described. The tantalum fiber precursor is chopped or cut into short lengths having a uniform fiber thickness and favorable aspect ratio. The chopped fibers are formed into a primary powder having a controlled size and shape, narrow/tight particle size distribution, and low impurity level. The primary powder is then agglomerated into an agglomerated powder displaying suitable flowability and pressability such that pellets with good structural integrity and uniform pellet porosity are manufacturable. The pellet is sintered and anodized to a desired formation voltage. The thusly created capacitor anode has a dual morphology or dual porosity provided by a primary porosity of the individual tantalum fibers making up the primary powder and a larger secondary porosity formed between the primary powders agglomerated into the agglomerated powder.

Abstract: A retractor system, kit and method of use includes a plurality of retractors for use in retracting a wound during a minimally-invasive hip replacement surgery to define an access space to a surgical site is discussed. Each of the retractors comprises a handle portion configured to be held by a user, a curved bend portion distal of the handle portion, and a wound contact portion attached to the curved bend portion. The wound contact portion is configured to contact tissue of the wound when at least a portion of the retractor is inserted through a skin incision that defines the wound. Each retractor also has a distal portion disposed distally of the wound contact portion, wherein the wound contact portion has a generally curved cross-sectional profile perpendicular to its length that is configured to prevent necrosis of the tissue during retraction. In addition, the cross-sectional profile provides an improved line of sight during the surgical procedure. Furthermore, the cross-sectional profile prevents the jamming of a cutting device, such as a reamer inserted through the incision, while the retractors retract the wound.
