Appl. No.:

10/163770

Assignee:

SciMed Lifesystems, Inc. - Maple Grove MN

International Classification:

B32B031/26

US Classification:

Abstract:

For weld bonding polymeric components, a bond monitoring device is utilized to sense emissivity from a bonding site to preferably determine the temperature of the material at the surface of the bonding site, in order to provide feedback information to a current generator that controls the thermal energy that is transferred to the bonding site. The bond monitoring device preferably comprises an infrared detector or pyrometer that determines the temperature at the surface of the bonding site by sensing the infrared radiation, which information is used to control current generation. The current generation device preferably comprises a radio-frequency current generator, which RF current is controllably used to create a magnetic field within a magnetic flux concentrator. When used with an mandrel of magnetically permeable material that is positioned close to the magnetic flux concentrator, the mandrel can generate resistive heat based directly on the supply of RF current. The present invention is particularly applicable to weld bonding of tubular type components, such as may be used to make up a medical catheter lumen, because a heatable mandrel can be inserted within a plurality of components having at least adjacently positioned portions that are to be weld bonded together.

International Classification:

A61F 11/00

US Classification:

606108, 128898, 264230

Abstract:

A catheter can be formed from an elongate shaft and a distal tip. The catheter can be formed by flaring a proximal end of the distal tip to form a flared proximal end and positioning the distal tip such that the flared proximal end of the distal tip overlaps a distal end of the outer layer. Heat and pressure are applied to melt and flow together a portion of the outer layer proximate the distal end of the shaft and the overlapped portion of the flared proximal end of the distal tip, thereby forming a joint between the elongate shaft and the distal tip.

US Classification:

156/158000, 156/304500, 156/294000

Abstract:

A method of bonding a first tubular member to a second tubular member to form a catheter shaft. The method comprising the step of providing a first tubular member including a distal end, a proximal end, and a lumen extending between the distal end and the proximal end thereof. The method further including the step of providing a second tubular member including a distal end, a proximal end, and a lumen extending between the distal end and the proximal end thereof. The method further including the steps of inserting a joining portion of the first tubular member into a joining portion of the second tubular member and applying heat the joining portions.

International Classification:

B23K 11/16

US Classification:

219118

Abstract:

Disclosed are methods and structures for joining metallic members. A welding material can be used between two metallic members that comprise different metals. The different metals can normally form brittle intermetallic compounds when welded to one another, and the welding material can inhibit the formation of the brittle intermetallic compounds.

Abstract:

A covered mandrel that includes a mandrel and a covering. The mandrel has an outer surface and comprises a first material. The covering is engaged to the outer surface of the mandrel and comprises a second material different than the first material. At least a portion of the covered mandrel is configured to scatter light.
