Disclosed herein is a system for releasing a ligament. In one embodiment, the system includes a proximal handle, a tubular body, and a flexible body. The tubular body includes a proximal end and a distal end. The handle is coupled to the proximal end. The flexible body extends through the tubular body and includes a tissue cutting portion. The flexible body is longitudinally displaceable relative to the tubular body to move the tissue cutting portion between a non-deployed state and a deployed state.

According to the present invention, there is provided a method for preparing an optically active compound, characterized in that said method comprises permitting a mixture of optical isomers relative to the carbon atom in the β-position in relation to the carbon atom bound to an esterified hydroxy group of an enol ester to hydrolyse either one optical isomer preferentially in the presence of an enzyme and allowing the carbonyl compound resulting from such hydrolysis to enrich the proportion of its isomer having either one configuration in the β-position in relation to the carbonyl group or allowing the enol ester left non-hydrolyzed to enrich the proportion of its isomer having either one configuration on the carbon atom in the β-position in relation to the carbon atom to which the esterified hydroxyl group bonds.

Apparatus for creating an anatomic space in tissue in a body including an introducer device having a tubular member with a bore extending therethrough. A tunneling shaft assembly is slidably mounted in the bore of the introducer device. The tunneling shaft assembly includes a tunneling shaft having proximal and distal extremities. A blunt tip is secured to the distal extremity of the tunneling shaft. A balloon assembly is provided. The balloon assembly is removably secured to the tunneling shaft. The balloon assembly includes a deflated collapsed balloon. A sheath encloses the balloon and is carried by the tunneling shaft. The sheath has a weakened region extending longitudinally thereof permitting the sheath to be removed to release the balloon.

The described devices are useful in the treatment of spinal disorders and pain. In particular, the described devices are designed to stabilize a portion of the spine by restoring and maintaining spacing between two adjacent vertebrae. The devices are compressible spacers that may be situated between the spinous processes of those adjacent vertebrae. The described inter spinous process spacers also allow a range of spinal motion and mimic the motion of a normally functioning spine.

There are provided a microporous film for an electric storage device separator, which can increase energy density and power density when used in an electric storage device, and which is excellent in handling properties in a processing step to the electric storage device, as well as an electric storage device separator and an electric storage device, using the microporous film. Specifically, provided is a microporous film for an electric storage device separator, characterized by including a porosity of 70% or more, a strength of 40 MPa or more in a longitudinal direction, an average pore size of from 40 to 400 nm, anuclear pores, and exhibiting biaxial orientation.
摘要:
A through-panel connector, comprising a female connector (10) and a male connector disposed on one side and the other side of panel (50) and fitted to each other through a mounting hole (51) formed in the panel (50). The female connector (10) comprises a plurality of flexible holding ribs (11). The holding ribs (11) are formed on the outer peripheral surface (32) of the female connector (10) opposed to the mounting hole inner peripheral surface (53) of the panel (50) so as to be extended along the inserting direction of the mounting hole (51) and separated from the outer peripheral surface (32) while being extended from the base end part (12) to the tip part (13) of the female connector (10) along the mounting hole inner peripheral surface (53). The holding ribs (11) are biased and held on the mounting hole inner peripheral surface (53) with the female connector (10) fitted to the panel (50).
摘要:
A developing apparatus includes a developer carrying member for carrying thereon and conveying a developer to a portion opposed to an image bearing member; a first chamber having the developer carrying member disposed in an opening thereof; a conveying member disposed in the first chamber for conveying the developer; a second chamber to which the developer is supplied from the first chamber through a first communicating portion and which supplies the developer to the first chamber through a second communicating portion to the first chamber; an agitating and conveying member disposed in the second chamber and rotatable to thereby agitate and convey the developer, wherein the second chamber and the agitating and conveying member are disposed while being inclined with respect to a horizontal direction; and developer supplying means for supplying a developer to be supplied, from just above an area of the second chamber.

This description deals with a medical device, specifically a prosthetic intervertebral disc having a compressible core that is mechanically interactive with the prosthetic disc's end plates thereby providing excellent torque or twisting transmission between the end plates.
摘要:
A lever-fit connector, wherein a rotation prevention lock (12) preventing a lever (5) from being rotated when male and female connector housing are fitted (joined) to each other is installed in the inner wall (6A) of a lever insert hole (6) in a female housing (2). A rotation lock recessed part (58) in which the rotation lock part (12D) of the rotation prevention lock (12) is engageably stored is formed in the peripheral surface of the lever (5). The angle of the rotation lock part (12D) is set so that the rotation lock part (12D) is drawn to the lever (5) side in excessive rotation by bringing the rotation lock part (12D) into contact with the side wall surface (58B) of the rotation lock recessed part (58).
摘要:
In a connector lock structure 1 provided at female and male connectors which can be fitted together, the female connector 2 has an engagement portion 14, and a slide lock member 13 is supported on the male connector 3 so as to move at least in connector-inserting and connector-withdrawing directions. The slide lock member 13 includes a retaining portion 16 for engagement with the engagement portion 14, and urging member 36 for urging the slide lock member 13. When the engagement portion 14 reaches an engagement position where it is engaged with the retaining portion 16 at the time when the female and male connectors are completely fitted together, the slide lock member 13 is automatically moved by the urging member 36, so that the retaining portion 16 is engaged with the engagement portion 14.
