A device, preferably a micro-device, is molded from a plastic material by injection molding, compression molding or embossing. A microabrader can be molded having microneedles for abrading the stratum corneum of the skin to form an abraded site in the tissue for enhancing drug delivery. The micro-device is molded using a mold assembly having a silicon molding surface. The silicon molding surface can include a recess corresponding to the desired shape and length of the microneedles. The silicon molding surface enables micron and submicron size features to be molded from polymeric materials without the polymeric material adhering to the mold surface. Micro-devices having molded features having micron and submicron dimensions can be rapidly produced without the use of a release agent.

Suture clips and suture clip loading, delivery, locking and severing devices in both catheter and endoscopic embodiments are disclosed that permit the delivery and application of suture clips directly in contact with or in close approximation to sutured tissue. The catheter or endoscopic versions incorporate a collet cage with a plurality of flexible collet fingers that captivate a suture clip ring and a suture clip plug for assembly with a suture. An outer sliding sleeve constrains the collet fingers when distally advanced to minimize potential trauma during delivery and assembly of the suture clip in close proximity to the stitched tissue. Proximal retraction of the sliding sleeve coupled with the distal advancement of a pusher against cam surfaces on the inner walls of the collet fingers causes the collet fingers to open. The catheter is designed to hold and assemble the suture clip in a first position and release the suture clip and sever the suture ends proximal to the suture clip in a second position. Single pusher two-step embodiments and double pusher three-step embodiments are disclosed. Suture clip designs with plugs having heads for use with the suture clip delivery catheter are also disclosed. A suture clip loading device for loading suture clip components into the delivery system as well as a threader for threading sutures into the suture clip systems are also disclosed. A method of loading, delivering and deploying suture clips is further disclosed.

Techniques and apparatus inhibit, limit, or remove biofouling and certain inorganic accumulations, to increase the longevity of accurate in-situ oceanographic and other underwater measurements and transducing processes. The invention deters formation of an initial bacterial layer and other precipitation, without harming the environment. The invention integrates an ultrasonic source into a sensor or other device, or its supporting structures. The ultrasonic source vibrates one or more critical surfaces of the device at a frequency and amplitude that dislodge early accumulations, thus preventing the rest of the fouling sequence. The ultrasonic driver is activated for short periods and low duty cycles, and in some cases preferably while the device is not operating.

To realize an increase in lifespan and a reduction in cost in an interlocking mechanism that causes a driving scroll and a driven scroll to rotate synchronously, a through hole is drilled into a peripheral edge portion of a driving scroll side end plate, and a pin member is fixed to the through hole. A base is provided on a driven scroll side spiral projection that faces the through hole. A columnar recessed portion is carved into an opposing surface of the base, and an aluminum rotary body is loosely fitted into the recessed portion. An eccentric hole is drilled into the rotary body, and the pin member is loosely fitted into the eccentric hole. The interlocking mechanism is disposed in an odd number at equal intervals on an outer edge portion of the scroll end plate such that loads exerted on the rotary body act in an identical plane.

A method of cleaning a substrate within a controlled environment includes placing the substrate into a high pressure vessel. The high pressure vessel is then supplied with a dense fluid under pressure. The dense fluid is contacted with the substrate for a selected period of time to at least partially remove a contaminant contained on the substrate. After the selected period of time, the vessel is depressurized to at least partially convert the dense fluid into a vapor. The vapor is then subjected to an energy field to form a plasma within the vessel which is used to treat the substrate for a second selected period of time. The thus cleaned substrate is then removed from the vessel.

The frame is configured and arranged to be rotatably secured to a second end of the shaft for operably engaging a paint roller head and rotating the paint roller head about an axis. The protrusion extends in a second axial direction from the distal end of the frame so as to prevent a distal end of a paint roller head operably engaged upon the frame from contacting a surface perpendicular to the axis of rotation. The flexure joint is configured and arranged to be interposed between and connect the second end of the handle and the first end of the shaft. The functional element is configured and arranged to be secured to a second end of the shaft. The flexure joint includes a receiving member with first and second transversely spaced opposing arms defining a transverse gap between the arms, a spherical member positioned within the gap, a connector in communication with the arms for adjusting the transverse width of the gap occupied by the spherical member and a spacing adjustment mechanism also in communication with the arms for adjusting the transverse width of the gap occupied by the spherical member.

An object of this invention is to make it possible to suppress early-stage oxidation of a substrate surface prior to oxidation processing, and to remove a natural oxidation film. For this reason, a method is provided comprising the steps of loading a substrate into a processing chamber, supplying a hydrogen-containing gas and an oxygen-containing gas into the processing chamber, and subjecting a surface of the substrate to oxidation processing, and unloading the substrate subjected to oxidation processing from the processing chamber. In the oxidation processing step, the hydrogen-containing gas is introduced in advance into the processing chamber, with the pressure inside the processing chamber set at a pressure that is less than atmospheric pressure, and the oxygen-containing gas is then introduced in the state in which the introduction of the hydrogen-containing gas is continued.
