Polymer link hybrid stent

InactiveUS7455687B2Improve column strengthHigh strengthStentsSurgeryCoronary arteriesMetallic materials
The present invention is directed to an expandable polymer link hybrid stent for implantation in a body lumen, such as a coronary artery along with a method of making the stent. The stent generally includes a series of metallic cylindrical rings longitudinally aligned on a common axis of the stent and interconnected by a series of polymeric links. The polymer links are formed by applying polymer layers between the rings and laser ablating the excess material. The polymeric material forming the polymeric links, provides longitudinal and flexural flexibility to the stent while maintaining sufficient column strength to space the cylindrical rings along the longitudinal axis. The metallic material forming the rings provides the necessary radial stiffness.

Method of bending sheet metal to form three-dimensional structures

InactiveUS20020184936A1Bending stress to the metal is minimized and controlledMinimize distortionEngineeringMetal sheet
A method for bending sheet metal includes introducing to the sheet metal thinned regions which are positioned either along or immediately adjacent to a bending line. These thinned regions allow the metal to be easily bent along the bending line using conventional hand tools or non-specialized machines. The thinned regions may be shaped as slots having a specific width, length, end shape, spacing from each adjacent slot, and depth into the metal sheet. According to one embodiment of the invention, each slot is cut through the entire thickness of the metal sheet. Other related embodiments require that the slots be only partially cut or etched thereby having a depth that is less than the thickness of the metal sheet. The thinned regions may be any appropriate shape as controlled by the shape of the bend, the type of metal, the thickness of the metal, the ductility of the metal, the angle of the bend, and the application of the metal (e.g., load bearing, etc). According to a second embodiment, two generally parallel sets of thinned regions are formed adjacent and generally parallel to the bending line. In a preferred application, the two sets of thinned regions are slots (cutting through the metal) and are staggered or offset with respect to each other.

Track-plate carriage system

Translational bone fixation assemblies, kits containing such assemblies, and methods of use are described herein. The described assemblies may be used in spinal fusion procedures in which a damaged or diseased disc (or part of a disc) is removed from between a pair of vertebrae and a spinal fusion spacer is placed between the vertebrae. The assemblies may be applied to an anterior portion of the affected vertebrae to span the affected disc space, and may be fixed to the vertebrae using bone screws. The assemblies may function to maintain the vertebrae aligned during the initial period following fixation in which fusion of the spacer to the adjacent vertebrae occurs. The assemblies may also function to share some of the axial spinal load applied to the fusion spacer to prevent extreme subsidence of the spacer into the vertebral body, such as where the patient has poor bone quality. The assemblies may also act to prevent the spacer from being expelled from the disc space during the initial post-operative period. Finally, these assemblies may be used in other parts of the body where the advantages of the assemblies are desired or applicable.

To insert the electrode system into the cochlea, a stylet wire is inserted into the channel or lumen of the electrode array while the electrode array is held within the sheath. The sheath is then removed, and the electrode array is then gently guided and pushed through a cochleostomy into the cochlea by extending the stylet wire to a desired depth. As the electrode array is thus inserted into the cochlea, the stylet wire is retracted and the electrode array remains implanted within the cochlea.
