摘要:
A medical device having an imaging function includes a shaft main body portion having an image acquiring lumen and a guide wire lumen extending from a distal side to a proximal side of the shaft main body portion. A proximal portion of the shaft main body includes a first shaft proximal portion in which the image acquiring lumen is disposed, and a second shaft proximal portion in which the guide wire lumen is disposed, and which are bifurcated. A shaft distal portion has a common lumen in which the image acquiring lumen and the guide wire lumen converge, a first hub portion is interlocked with the first shaft proximal portion, a second hub portion is interlocked with the second shaft proximal portion, and a hub casing collectively covers the first shaft proximal portion, the second shaft proximal portion, the first hub portion and the second hub portion.

An imaging medical device includes a shaft main body portion having an image acquiring lumen and a guide wire lumen. The shaft main body portion includes a first shaft proximal portion in which the image acquiring lumen is disposed, and a second shaft proximal portion in which the guide wire lumen is disposed, with the two being bifurcated. First and second hub portions are interlocked with the first and second shaft proximal portions respectively, and a transducer unit is fixed to a drive shaft. Reference line X represents the axis line of the shaft main body portion, θ1 represents the inclination of the central axis of the first hub portion relative to the reference line, θ2 represents the inclination of the central axis of the second hub portion relative to the reference line, and the relationship of |θ1|>|θ2| is satisfied.

A spiral unit includes a base tube extended along a longitudinal axis and made of a first thermoplastic resin, and a fin disposed on an outer peripheral surface of the base tube along a fin axis spirally extended around the longitudinal axis and made of a second thermoplastic resin. The fin includes a strip portion provided in a state of being bonded to the outer peripheral surface of the base tube and spirally extended along the fin axis. The second resin being mixed with a magnetic material in the strip portion.

Methods and systems for no-glue pocketed spring unit construction. Rows of pocketed springs, preferably arranged into modules of more than two pocketed springs surrounding a central hole, are ultrasonically welded together when paired vibrating probes and anvils press layers of pocketed spring fabric from the rows of pocketed springs together and a welding pulse is transmitted to the vibrating probe.

A method of splicing together a first composite core and a second composite core can include: positioning a first flange of the first composite core adjacent to a second flange of the second composite core, applying an adhesive, and locating a first magnet and a second magnet to provide a pressure on the adhesive.

A method of manufacturing a core stiffened structure includes orienting the plurality of core wafers in a non-uniform pattern onto a first face sheet, the non-uniform pattern producing non-uniform spacing between adjacent core wafers; assembling a second face sheet onto the plurality of wafers; and curing an adhesive to create a bond between the plurality of wafers, the first face sheet, and the second face sheet.
摘要:
A panel former is provided for producing a panel that is formed from polymer tubing for solar collectors, heat exchangers, and other devices. The panel former can receive the tubing and continuously wrap the tubing around a drum so that support members can be welded to the tubing. After the support members are welded to the tubing, the tubing can be cut along a line substantially parallel to the support members to remove the tubing from the panel former and to form the risers in a panel.

The present disclosure is directed to a method of manufacturing a catheter wherein a dual lumen catheter body and at least one distal tip member are separately formed and the at least one distal tip member is subsequently assembled to the dual lumen catheter body. The components may be assembled using a heating process or, alternatively, using adhesives.

A catheter shaft bond arrangement includes a first catheter shaft defining a first lumen, a second catheter shaft defining a second lumen, and a first bonding member. The first bonding member is configured to bond with the first and second catheter shafts to create a molded bond upon application of heat to the first bonding member. The molded bond provides a fixed axial and radial orientation of the first and second catheter shafts relative to each other. The molded bond can be generated in some arrangements without the use of the first bonding member. In other arrangements, two or more bonding members can be used to create the molded bond.
摘要:
Methods of forming catheters are disclosed, together with methods of forming split tip catheters. In one aspect of the invention, the manufacturing methods can include the steps of: providing first and second catheter tubes each having a substantially D-shaped cross-section, and attaching at least a portion of longitudinal lengths of the first and second catheter tubes along flat surfaces of the first and second catheter tubes to form a dual lumen catheter assembly. The tubes can be fused along at least about 10%, preferably along at least about 50%, more preferably in some applications along at least about 70%, 80% or 90% of the longitudinal length.
