A method of manufacturing a catheter includes providing an outer shaft having a lumen therethrough and at least one catheter component disposed at least partially within the lumen, placing an inner shaft within the lumen such that the at least one catheter component is located between the shafts, thereby forming a catheter assembly having an outer surface, and applying energy to the catheter assembly to melt at least the outer shaft to bond the outer shaft to the inner shaft. A unitary catheter shaft having the at least one catheter component substantially embedded therein results. The durometer of the outer shaft may differ from the durometer of the inner shaft, such that the catheter shaft varies radially in durometer. The durometer of the catheter shaft may also vary longitudinally. A shaping wire may be provided to form the distal end of the catheter shaft into a desired shape.

The invention relates to a surgical instrument for at least partially occluding a body conduit comprising a first jaw, a second jaw opposing the first jaw and moveable relative to the first jaw to occlude the conduit, and an insert being mounted by at least one of the first and second jaws with a length of the insert extending along at least one of the first and second jaws. One of the first and second jaws may further comprise a retention barb to provide a friction fit with the insert. The insert is flexible, disposable and may be formed by injection molding. The retention barb may be a three-sided or multiple-sided barb that is formed at the proximal end of at least one of the first and second jaws. The first and / or second jaws may be bent and / or curved. In another aspect, the insert comprises an outer wall and an inner wall for fitting over the jaw, and the inner wall further comprises a molded, rectangular raised ring formed at the proximal end to aid the retention of the insert over the retention barb of the jaw. The insert may be removed from the jaw by pulling the insert in a distal direction to overcome the friction fit of the retention barb. The insert may further include a soft tip covering the distal end of one of the jaws to minimize trauma during surgery. The distal ends of the jaw and the insert may be tapered to allow ease of installation and removal. In another aspect, the insert and jaws may be removably attached to one another in a snap-fit relationship where the jaws may include one or more holes and the insert may include one or more projections. It is appreciated that the holes and projections may vary in width, depth and height depending on application.

A stage tool operable with a plug is used for cementing a tubing string in a wellbore annulus. The tool can have a housing with a closure sleeve movably disposed in the internal bore of the housing. When pressure is applied downhole to the tool, a breachable obstruction on an exit port of the tool's bore opens and allows fluid such as cement slurry to communicate to the wellbore annulus. When cementing through the open tool finished, a plug deployed downhole lands on a seat in the closure sleeve, and applied fluid pressure in the tool's bore against the seated plug closes the closure sleeve relative to the housing's exit port. Rotational catches between the housing's bore and the closure sleeve prevent the closure sleeve from rotating. Preferably, an intermediate sleeve is used in the housing's bore and has rotational catches on each end. When the closure sleeve moves closed, the intermediate sleeve is also moved to engage between the catches on the end of the closure sleeve and the catches on a shoulder of the housing's bore. In further arrangements, a hydraulic mechanism on the tool can facilitate movement of the closure sleeve in response to a fluid pressure component.

An objective lens holder of the present invention includes: (i) a cavity, having an entrance and an exit, which guides, to an objective lens, an incident light beam entering the entrance, the exit being provided on a side of the cavity where the objective lens is housed; and (ii) an aperture having an opening for limiting, to an effective diameter of the objective lens, a beam diameter of the incident light beam passing through the cavity. The cavity is surrounded with internal wall surfaces facing each other so that space between the internal wall surfaces gradually increases from the opening of the aperture toward the entrance or the exit. This makes it possible to provide a highly rigid objective lens holder that allows high speed read / write operations.

A pressure bladder comprising a substantially cylindrically shaped interior chamber is formed from a pliable, yet chemically resistant material, for example a fluoropolymer, such as FEP (fluorinated ethylene propylene). The interior chamber of the pressure bladder is hydraulically sealed at a distal end and is hydraulically coupled to a pressure sensor at a proximate end. Both the pressure bladder and pressure sensor are filled with an inert, non-reactive, stable measurement fluid. Optionally, a support mandrel with a second, smaller substantially cylindrically shaped interior chamber is hydraulically coupled between the pressure bladder and the pressure sensor and also filled with the measurement fluid. The pressure sensor is electrically coupled to electrical conductors, as is an optional thermistor. The conductors are received within a conductor protective tubing. The pressure sensor is disposed within a protective isolation tubing which is hydraulically coupled to the conductor protective tubing and to either the pressure bladder or support mandrel.

A waterproof mechanism for a satellite antenna is to separate a waterproof cover of the known technology into two components of a fixing cover and a thin wall cap used for compressing an O-ring, cause the thin wall cap and the O-ring to be combined closely and stably on the upper end of a wave-guide tube, and enable the stability and the strength of the entirety to be increased. But, the thin wall cap is unnecessary to have a same thickness as the fixing cover. Therefore, the thickness of the thin wall cap can approximately be reduced to 3 mm. This can increase broadly the passing rate of satellite signal and allow a low noise block with integrated feed (LNBF) to have a better satellite signal receiving effect.
