Intravascular implant systems and methods of positioning and detaching implants are described. One such system carries an implant by retaining an engagement member in a position proximal to an aperture at a distal end of the delivery system. The engagement member is retained proximal to the aperture by an elongate member that is coupled to the implant. Once the implant is in a desired implant position, the elongate member is released from the engagement member, and the implant is allowed to move away from the delivery system.

Provided is a method for manufacturing a gas sensor capable of securing airtightness without a chip in a sensor element. The method includes a step of obtaining an assembled body constituting the gas sensor, including steps of: causing one end of the sensor element to abut to a positioning member for positioning the sensor element; applying a force F1 to the annularly-mounted members including a powder compact annularly mounted to the sensor element under a state that the sensor element is positioned and thereby compressing the powder compact so as to fix the sensor element inside of the tubular body, applying a force F2 larger than the force F1 to the annularly-mounted members under a state that the sensor element is not positioned and thereby further compressing the powder compact, so as to hermetically seal inside of the tubular body.

A self-aligning swaging punch is provided for adjoining together a pin and a workpiece having a pinhole. The swaging punch comprises a shaft and a tip having an open-ended cavity. The shaft transfers an axial force from a press or hammer to the tip. The tip transfers the axial force from the shaft to a top surface of the workpiece near the pinhole. The tip may be spherical in shape for evenly deforming the workpiece near the upper edge of the pinhole. The open-ended cavity receives the pin therein and allows the pin to extend at least partially into the open-ended cavity while the tip contacts the workpiece. The open-ended cavity also ensures that the swaging punch is aligned with the pinhole and perpendicular to the surface of the workpiece when the pin is inserted into the pinhole such that the workpiece evenly deforms and presses against the pin.

A cheek plate for producing a non-detachable pipe joint having an upper cheek half and a lower cheek half, at least one swivel pin which pivotally mounts at least one cheek half, and a receiving region formed between the upper cheek half and the lower cheek half and having a receiving region axis, the at least one cheek half being able to pivot between an open position and a closed position substantially transversely with respect to the receiving region axis. The problem of providing a cheek plate such that the cheek plate permits pressing transverse to the receiving region axis and at the same time a reduction in workpiece size is permitted is solved in that at least one pushing unit is provided, the pushing unit being displaceable at least partially in parallel with the receiving region axis.

A crimping tool and method for reducing an external dimension of a compressible prosthetic device, the crimping tool comprising a first member comprising a first control surface collapsible between a first state and a second state, the first member having a first open end configured for introducing the prosthetic device when the first control surface is in the first state, and a second open end configured for allowing locking of the prosthetic device when introduced into the first member; an engagement portion that moves the first control surface from the first state to the second state; and an actuator portion for moving the first member along the longitudinal axis allowing the engagement portion to interact with the first member.

A fence includes first elongated tubular members, each one of which is configured to extend vertically from ends of the first elongated tubular members positionable proximate to a support surface (e.g., the ground). The fence also includes second elongated tubular members extending between the first elongated tubular members, each of which is configured to extend parallel to the support surface. The fence further includes receivers defined by apertures formed in the first elongated tubular members, each of which extends outwardly from respective first elongated tubular members so that each one of the second elongated tubular members can be fixedly attached to corresponding ones of the first elongated tubular members. In some embodiments, one or more of the first elongated tubular members and/or the second elongated tubular members can have a circular cross-section. The second elongated tubular members can be fixedly attached the first elongated tubular members with and/or without welding.
