Abstract: A system for performing surgical repair of the spine includes a distractor and a permanently implanted bone plate system. A surgical repair methodology is also disclosed that employs an implanted bone plate system with a substantially void internal volume which is attached to adjacent vertebrae subsequent to the distraction and adjustment of curvature of the vertebrae and prior to the excision of disc and/or end plate tissue through the bone plate. The device further facilitates the subsequent delivery of an interbody repair device for the purpose of either fusion or dynamic stabilization, such as by disc arthroplasty. The plate may be permanently implanted, such as when a fusion between the attached vertebral bodies is desired, but it need not be permanently implanted.

Abstract: In an internal sinus manipulation procedure for augmenting bone of a dental patient between a bony floor of the patient's sinus and a raised portion of the patient's sinus membrane, employing a bone graft material condensing instrument comprising a longitudinally extending handle and a laterally extending distal head having an upper surface bounded by vertically extending substantially flat sides and a flat horizontally extending lower surface and placed within the raised portion of the patient's sinus membrane to condense a previously placed bone graft forming material upon a turning thereof.

Abstract: A number of orthopaedic surgical instruments are also disclosed. A method, apparatus, and system for fabricating such instruments are also disclosed.

Abstract: A laryngoscope adaptor cap for use with existing government issue military flashlights designed for use in night time battlefield conditions. A filter disc filters out visible light and a light seal design prevents leakage of visible light from an assembled laryngoscope. The adaptor cap is crush resistant, impact resistant, has a high melting temperature, is disposable and allows the attachment of conventional laryngoscope paddles. It allows for night time endotracheal intubation in conjunction with military issue night vision goggles in the absence of visible light.

Abstract: An instrument assembly for placing a guide pin in a femoral neck of a patient with reference to a medullary guide wire for use in resurfacing a femoral head. The assembly comprises a femoral neck clamp configured to define a femoral neck center. A pin guide attaches to the femoral neck clamp. A pin guide portion of the pin guide is configured to define a pin guide path passing through the neck center. The pin guide portion is linked to pin guide engagement portion of an adjustable goniometer. The goniometer maintains a specific angle between the pin guide engagement portion and the medullary guide wire, and in turn maintains the pin guide path at the specific angle.

Abstract: Apparatus for delivering stents to body lumens include a flexible catheter shaft, an expandable member, a tubular prosthesis selectively movable in an axial direction over the expandable member, and a stop member disposed on the catheter shaft near the distal end of the catheter shaft for stopping the prosthesis at a deployment position on the expandable member. A variety of different stop members are provided according to various embodiments, such as stop members disposed outside the expandable member, stop members disposed inside the expandable member, movable stop members, and the like. Methods of delivering stents are also provided.

Abstract: A releasably locking dilator and sheath assembly and methods for releasing the dilator from the sheath and longitudinally splitting the sheath are provided. The assembly includes a dilator having a dilator hub and a sheath having a sheath hub. The sheath hub has a valve and two opposing winged tabs, each tab having a perpendicular portion and an angled portion as well as a female threaded portion. The dilator hub has a male threaded portion designed to engage the female threaded portion of the sheath hub. The dilator is released from the sheath by rotating the dilator 90° in relation to the sheath and pulling the dilator out of the sheath. The sheath is longitudinally split by creating a couple on each of the winged tabs thereby forcing the sheath and the sheath hub to split longitudinally. With the sheath and sheath hub split longitudinally, the sheath is removed from around a catheter while leaving the catheter in place.

Abstract: The invention is directed to a system and method for releasably holding a surgical instrument (14), such as an endoscopic instrument configured for delivery through a small percutaneous penetration in a patient. The instrument comprises an elongate shaft (100) with a pair of mounting pins (116) laterally extending from the shaft between its proximal and distal ends. An instrument holder comprises a support having a central bore (202) and an axially extending slot (204) for receiving the instrument shaft and the mounting pins. A pair of locking slots (206) are cut into the support transversely to and in communication with the axial slot so that the mounting pins can be rotated within the locking slots. The instrument support further includes a latch assembly for automatically locking the mounting pins within the locking slots to releasably couple the instrument to the instrument holder.

Abstract: The present invention, in an exemplary embodiment, provides a stent, which combines many of the excellent characteristics of both silicone and metal stents while eliminating the undesirable ones. In particular, a principal objective in accordance with the present invention is to provide a family of stents where the relative hardness/softness of regions of the stent can differ from other regions of the stent to provide additional patient comfort and resistance to compression forces. Exemplary embodiments provide a stent that is covered so as to provide certain predefined characteristics. In particular, a covered stent is provided that is coated internally such that the outer scaffolding surface of the stent has enhanced friction points while the internal surface exemplifies certain characteristics.

Abstract: A flexible extension for a shape memory polymer occlusion removal device. A shape memory polymer instrument is transported through a vessel via a catheter. A flexible elongated unit is operatively connected to the distal end of the shape memory polymer instrument to enhance maneuverability through tortuous paths en route to the occlusion.

Abstract: A vaso-occlusive device includes a microcoil formed into a minimum energy state secondary configuration comprising a plurality of curved segments, each defining a discrete axis, whereby the device, in its minimum energy state configuration, defines multiple axes. In a preferred embodiment, the minimum energy state secondary configuration comprises a plurality of tangentially-interconnected, substantially circular loops defining a plurality of discrete axes. In an alternative embodiment, the minimum energy state secondary configuration defines a wave-form like structure comprising a longitudinal array of laterally-alternating open loops defining a plurality of separate axes. In either embodiment, the device, in its minimum energy state secondary configuration, has a dimension that is substantially larger than the largest dimension of the vascular site in which the device is to be deployed.

Abstract: A stent comprises at least one band of interconnected cells selected from the group consisting of S-shaped cells and mirror image S-shaped cells. Each cell has a top end and a bottom end. The top end of each cell is attached to the bottom end of an adjacent cell in the band. Adjacent bands may abut one another or may be joined by connecting members.
