Opposable surgical clamp members having opposable resilient pads with wedge-shaped and cylindrical protrusions extending from the surfaces of the pads and the use of such members for occluding vessels and other tubular body structures are described. The protrusions are arranged such that when the members are moved toward one another, the protrusions of one pad interdigitate with the protrusions of the other pad. Upon engagement with a vessel, portions of the vessel are forced into the interdigital spaces providing for improved gripping of the vessel. The protrusions also resist lateral or transverse movement of a clamped vessel relative to the pads. The existence of through holes under the pad surface alters the relative resiliency of the pad, allowing for an overall pad resiliency that minimizes trauma to a clamped vessel while allowing the local resiliency of the protrusions themselves to be of a hardness to avoid excessive deflection and retain the desired shape and gripping ability.

A microactuator assembly for a hard disk drive head suspension has an expandable base of stainless steel sheet material defining a negative lead affixed to the negative electrode on the bottom surface of a piezoelectric element, and a piece of stainless steel sheet material defining a positive lead attached to the positive electrode on the top surface of the piezoelectric element. The leads may be affixed directly to the piezoelectric element via conductive adhesive. The microactuator assembly can be assembled separately, and then laser welded into place on a suspension. A bond pad made of stainless steel sheet material extends from the flexible circuit, is electrically connected to the microactuator driving voltage conductor within the flexible circuit through a via, and is electrically isolated from the suspension substrate by an insulating film. The microactuator unit positive lead is mechanically and electrically connected to the bond pad via laser welding.

A method and apparatus for providing metal or non-metal vessels, including straight and curved pipes and various pipe connections, such as T's, elbows, swages, etc., and pressure containing vessels such as tanks, with an external composite lining of a webbing of biaxial or triaxial weave preferably composed of fiberglass which is pre-impregnated with a high temperature heat curable polymer composition capable of being heat cured at a temperature range of from about 275° F. to about 375° F. The vessel is prepared for bonding by abrasive cleaning and by solvent cleaning. Metal imperfections are then filled with an epoxy. A small amount a quick setting epoxy is employed to attach one end of the web to the external surface of the vessel in oriented position for wrapping of the web in intimate surface-to-surface contact with the vessel. During wrapping only enough tension is applied to the pre-impregnated webbing to eliminate any wrinkles. The number of layers of the impregnated webbing will be determined by the safe pressure containing capability of the pipe or vessel and its composite lining. An external heating element is then placed about the wrapping of pre-impregnated webbing material so as to be in substantially intimate relation therewith and is energized to apply sufficient heat for a sufficient period of time to completely cure the epoxy surface filler and to cure the polymer resin components of the pre-impregnated woven wrappings of webbing.
