Catheter having a multi-section tubular member and method of making the same

A multi-section tubular member including a sleeve surrounding and bridging a joint between a first section and a second section of the tubular member, and a method of forming a multi-section tubular member are disclosed. A polymeric sleeve may extend over a portion of the first section and an adjoining portion of the second section. A length of heat shrink tubing may be placed over the sleeve and heated, thereby compressing the heat shrink tubing around the sleeve. The sleeve may then be thermally bonded to each of the first section and the second section. The heat shrink tubing may then be removed, leaving the sleeve securely joining the first section and the second section to form a multi-section tubular member.

Method for connecting plastic tubes by plastically deforming and widening connecting stub
09625069 · 2017-04-18 · ·

A method for coaxially connecting a first plastic tube (10, 110) to a second plastic tube (20, 120), said plastic tubes (10, 20) in particular being provided as part of a medical catheter (102), the two plastic tubes (10, 20) being connected by way of a tubular connecting piece (50), characterized in that the first plastic tube (10) and/or the second plastic tube (20) are integrally molded from the outside onto the tubular connecting piece (50) using a forming process such that an adhesive and/or positive connection is produced.

DUCT WITH SHAPE MEMORY MATERIAL, AND INSTALLATION METHOD

Ducting and/or duct couplings can be formed from shape memory polymer material, with the material for example being additively manufactured. The use of shape memory polymer material for one or more of the duct portions may allow for easier installation of the ducting, for example allowing the ducting to be warped and/or bent to fit into or through places that are hard to reach or hard to maneuver through, with the ducting then heated to cause it to return to a predetermined memory shape. The coupling of duct portions together may be accomplished by the duct portions including a shape memory polymer material, with for example ends of the duct portions fitted together, and then heated to use a shape memory property of the material to effect coupling. Heating of the shape memory polymer material also softens the material, allowing it to move to a previously set shape.

Method and device for splicing multifilament textile fibers

A method for splicing two bundles (1, 2) of multifilament textile fibers comprises: inserting an end portion of a first bundle (1) into a first end of a heat-shrinkable sheath (10) and an end portion of a second bundle (2) into a second end of the sheath, axially opposite the first end, until the ends of the end portions of the two bundles are facing each other; inserting a curable organic material inside the sheath (10) in a space separating the end portions of the bundles (1, 2); heating a portion of the heat-shrinkable sheath (10) surrounding a joining portion (9) to a predetermined temperature; curing the curable organic material; and removing the sheath (10).

20170055943 · 2017-03-02 ·

An imaging window of an imaging catheter includes a first imaging window section and a second imaging window section. The first imaging window section has a finite length and is formed from a first material having a flexural modulus. The second imaging window section has a finite length and is formed from a second material having a flexural modulus. The flexural modulus of the first material is different than the flexural modulus of the second material.

A catheter includes a balloon and a shaft having a coaxial portion including an outer tubular member having a bore, a transition neck, an access fitting adjacent the proximate end of the catheter shaft for directing a guidewire into the catheter shaft, an inflation port, a guidewire tubular member disposed coaxially in the outer tubular member, the outer tubular member and guidewire tubular member defining a first, annular inflation/deflation lumen fluid communication with the inflation port, at least one second inflation/deflation lumen separate from and non-coaxial with the guidewire tubular member and having a cross-sectional area less than the cross-sectional area of the first inflation/deflation lumen and opening at a proximate end into the first inflation/deflation lumen and at the distal end of the transition neck.

Mesh to flexible screen frame laminator

A mesh to flexible screen frame laminator includes a first table with a horizontal surface and an alignment fence, a second table that is lower than the first table and a first pair of selectively driven heater rollers which are shiftable between a raised position and a lowered position relative to the first table. A cradle is located adjacent the first table and above the second table and at least a portion of the cradle is shiftable between a raised position and a lowered position, the raised position being substantially coplanar with the first table. A second pair of selectively driven heater rollers is shiftable between a raised position and a lowered position relative to the second table and is oriented transversely to the first pair of heater rollers. A third table is located adjacent the second table and at a height substantially coplanar with the second table.
