A balloon catheter including a dedicated contrast fluid lumen is disclosed. The contrast fluid lumen extends through the catheter shaft to a contrast fluid delivery port located proximate the inflatable balloon and is configured to deliver contrast fluid to a target location. The catheter shaft includes a joint located proximate the contrast fluid port formed between a distal end of a proximal outer tubular member, a distal end of an inner tubular member and a proximal end of a distal outer tubular member. A guidewire tube, defining a guidewire lumen, may extend through the lumen of the proximal and distal outer tubular members.

A bush main body having a circumferential part divided by a first virtual plane includes a first portion that is extended over a predetermined circumferential distance from the first virtual plane, a second portion that is disposed opposite the first portion with the first virtual plane sandwiched in between and is extended over a predetermined circumferential distance from the first virtual plane, and a third portion that is a portion other than the first and second portions. The inside diameter of the inner peripheral surface in a second virtual plane that includes an axial center and is perpendicular to the first virtual plane is set to be greater than the inside diameter of the inner peripheral surface in the first virtual plane while the first portion is in contact with the second portion in a no-load state before bonding to the stabilizer bar.

A stabilizer bush includes a bush main body, an annular lip, and an adhesive layer. The bush main body has a first inner peripheral surface and is formed of a cylindrical rubber elastic body. The first inner peripheral surface is to be attached to a stabilizer bar. The annular lip has a second inner peripheral surface contiguous to the first inner peripheral surface, is formed integrally with the bush main body, and is axially projected from the side toward the axial center of the axial end of the bush main body. The adhesive layer is formed of an adhesive that is applied to the first inner peripheral surface and to the second inner peripheral surface.

Method of making a balloon catheter includes melt-extruding a thermoplastic polymeric material into a tube, cooling the extruded tube, placing the extruded tube within a capture member and biaxially orienting the polymeric material of the extruded tube while simultaneously tapering at least a section of the extruded tube by radially expanding the extruded tube with pressurized media in the tube lumen and axially expanding the extruded tube with an external load applied on at least one end of the tube as an external heat supply traverses longitudinally from a first end to a second end of the extruded tube in the capture member, wherein an overall axial load on the tubing is varied as at least a section of the tube is heated. The method includes cooling the expanded tube to form a tapered biaxially oriented nonporous thermoplastic polymer tubular member and sealingly securing a balloon proximate a distal end of the tubular member.

An apparatus including a first hollow tube having an inner chamber and an outer peripheral surface, a cable having outer insulation and an inner conductor wire, and a hand held device for blowing hot air. The first hollow tube may have an inner diameter which is greater than an outer diameter of the cable so that the first hollow tube can be slid over the cable, so that a portion of the cable resides in the inner chamber of the first hollow tube in a first state. The cable may have a length which is substantially greater than a length of the first hollow tube. The hand held device for blowing hot air may be configured to blow hot air on the outer peripheral surface of the first tube, in the first state, to cause the first tube to shrink and become attached to the cable to repair a defect in the cable.

The invention relates to a sonotrode for an ultrasound welding system for welding workpieces (20, 30), comprising a pressure element (2) which has a contact surface, which pressure element can be applied to carry out the welding process with said contact surface on one of the workpieces (20) to be welded to each other, wherein the contact surface has an annular design. A centering pin axially projecting over the contact surface is arranged inside the annular contact surface. The invention also relates to a method for welding a connection element (20), in particular an adapter for a PDC sensor, to a component (30), in particular an exterior add-on part of a motor vehicle.

A maple sap line system and method for spin welding provides secure, unobstructed lines for collecting sap by creating a hermetically sealed connection between a lateral line and a mainline. A fitting connects the mainline to the lateral line. The fitting is spin welded to the mainline at a contact interface. The fitting comprises a protruding member that easily melts to create the frictional weld. The fitting has an elongated body comprising barbs that receive the lateral line. The fitting has a channel that enables fluid communication between the mainline and the lateral line. The flanges in the fitting register with a chuck to rotate the fitting against the main line at a high rpm. Molten debris formed in the channel is dislodged by drilling with a collared drill. The drilling provides fluid communication and creates a smooth inner surface in the mainline, and cuts off flanges from the fitting.

A composite camshaft is made by simultaneous through transmissive laser welding cams, bearing assemblies and load introduction parts to a fiber composite support tube.

A method for forming a connection between two tubular sections having a polymeric outer surface jacket, using electrofusion to fusion bond a casing of similar, non-crosslinked polymer to the outer surface of the tubular sections.

A device (20) for installing a tubular junction sleeve inside a pipe (1), having a mandrel (20a) of longitudinal axis (XX) supporting on its surface at least a first peripheral chamber (21) having a wall (21a) that is radially expandable by inflation. The first wall including at least one electrical connector (21b) suitable for being connected to one end of said heater wire. The connector being connected to an umbilical (24) including at least a compressed air feed duct for inflating said the first chamber and an electrical power supply duct connected to the electrical connector. The device being characterized in that the mandrel supports on its outer surface a second peripheral chamber (22) having a wall (22a) that is radially expandable by inflation, and also a weld inspection device (23) arranged in the longitudinal direction of the mandrel.
