A hybrid stent that is defined as having a central section that is balloon expandable and end sections that are self-expanding. The entire stent is mounted on a balloon of a balloon angioplasty catheter. One way to retain the self-expanding portion of the stent onto a balloon onto which it has been nested is to place a cylindrical elastomer tube around each of the self-expanding end sections of the stent. Another way to retain the hybrid stent onto a stent delivery system is to use a conventional sheath that is pulled back to initiate stent deployment

An intraocular-lens insertion device is adapted to deform a deformable intraocular lens into a smaller size and insert the intraocular lens into an eye via an insertion tube. An intraocular-lens guide is provided on the inner surface of the insertion tube. The guide may be a rail-shaped projection or a groove, which extends parallel to a direction along which the intraocular lens is pushed out. A stress release structure is provided on the insertion tube in order to release stress of the intraocular lens produced due to deformation thereof. Moreover, a frictional-resistance increasing structure is provided on the inner surface of the insertion tube to be located in the vicinity of the stress release structure. The frictional-resistance increasing structure increases frictional resistance between the inner surface of the insertion tube and the intraocular lens. The frictional-resistance increasing structure may be a roughened surface which completely or partially covers the inner surface of the insertion tube.

A system, apparatus, and method for local insertion of analog or digital material into a television broadcast signal. A central insertion control unit controls the insertion of additional material while a remote insertion control unit locally controls the insertion of the additional material.

The check valve according to the invention significantly reduces the generation of noise by producing an asymmetrical circulation around the closing body causing a force resulting from the flow and acting on the closing body to have a transverse component in relation to the opening direction, as a result of which increased friction and damping are generated in the closing body guide. The closing body may be asymmetrically embodied, or the housing wall encompassing the closing body may be provided with a conduit extending in the opening direction over at least a part of the travel path of the closing body.

An outer needle of a bone cement injection puncture needle has first side holes near the tip, and second side holes near the base. When an inner needle is removed from the outer needle and an inner tube is inserted into the outer needle in place thereof, a reduced-pressure passage is formed between the outer needle and the inner tube. When bone cement is injected into a bone, gas and liquid in the bone pass through the reduced-pressure passage and are discharged from the body, thereby preventing increased pressure in the bone. As a result, the bone cement can be prevented from leaking to outside of the bone.

A brachytherapy apparatus is composed of a tubular needle with forwardly protruding cutting edges at its tip, a holder supporting the needle and a driver for electromechanically causing the needle to undergo a continuous or oscillatory rotary motion around its axis and/or a reciprocating linear motion in the longitudinal direction such that its front opening at its tip can reliably reach a specified position inside a patient's tissue without being deflected or bowing when it encounters an obstruction such as a calcification or a small bone. Such motions may be provided by a piezoelectric hammer and a piezoelectric tamper. After the needle is thus correctly positioned, a brachytherapy device such as a radioactive seed or a reflector may be pushed through and out of the needle by means of a pusher as the needle is retracted to leave a track inside the tissue. A quickly hardening liquid may be thereafter injected through the needle to immobilize the deposited brachytherapy device. Another brachytherapy device may be deposited similarly after the needle is retracted by a specified distance. A plurality of brachytherapy devices may be preliminarily prepared as a unit having them linearly arranged inside a hardened liquid and mutually separated by specified distances such that they can be pushed together through the needle, or they may be injected together with a quickly hardening liquid.
