A method for reducing a dielectric constant of a cured film, includes: introducing a source gas at a flow rate of A, a porogen gas at a flow rate of B, an oxidizing gas at a flow rate of C, and an inert gas into a reaction space in which a substrate is place; increasing a ratio of B / (A+B) used as a parameter for controlling a dielectric constant of a cured film, by a degree substantially or nearly in proportion to a target decrease of dielectric constant of a cured film; applying RF power to the reaction space, thereby depositing a film on the substrate by plasma CVD; and curing the film to remove the porogen material, thereby forming pores in the cured film.

A knotless bone anchor and method for securing soft tissue, such as tendons, to bone, includes a plurality of discrete components. In one variation of the invention, the bone anchor includes a proximal toggle component, an intermediate plug component, and a distal sleeve component. Suture is looped around the plug component and once the anchor is actuated, the suture is compressed between the plug and the sleeve components. Advantageously, one or more of the components may be made of a biocompatible polymer. The polymeric components may be detachably joined to a drive shaft using a plurality of sacrificial fills. The sacrificial fills are broken or severed during deployment of the anchor. Related instruments and methods are also described.

Methods, devices and systems facilitate retention of a variety of therapeutic devices. Devices generally include an anchoring element, which has been designed to promote fibrotic ingrowth, and an anchored device, which has been designed to firmly engage the complementary region of the anchoring element. The anchoring element may be placed in a minimally invasive procedure temporally separated from the deployment of the anchored device. Once enough time has passed to ensure appropriate fixation of the anchoring element by tissue and cellular ingrowth at the site of placement, the anchored device may then be deployed during which it firmly engages the complementary region of the anchoring element. In this manner, a firm attachment to the implantation site may be made with a minimum of required hardware. Some embodiments are delivered through a delivery tube or catheter and while some embodiments may require laparoscopy or open surgery for one or more of the placement procedures. Some embodiments anchor devices within the cardiovascular tree while others may anchor devices within the gastrointestinal, peritoneal, pleural, pulmonary, urogynecologic, nasopharyngeal or dermatologic regions of the body.

Noise reduction sandwich panel, notably for an aircraft turbojet engine.In order to produce a noise reduction sandwich panel having a structure with two degrees of freedom, inserted separative components (20) are placed into the hexagonal cells (16) of the unique waffle core of the panel. More specifically, the separative components (20) have an substantially circular external peripheral edge, which allows them to be easily assembled, in spite of the deformations of the walls (18) of the cells (16) due to manufacturing tolerances and to the optional forming of the waffle core. Advantageously, several separative components (20) are supported by a same positioning unit (22), which then allows relative displacement between the separative components.
