Abstract
Abstract A method of bonding sections of a catheter body together in abutting relationship including the steps of providing a temperature resistance polymeric sleeve, which sleeve preferably has a spirally wound metallic wire imbedded between its inner and outer diameters. The sleeve is inserted into ends of tubing segments to be joined together to form a catheter body. Then heat is applied over the area including the sleeve to melt the tubing over the sleeve.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
128 words
A method of bonding first and second tubing segments together and to a temperature resistant sleeve to form a composite catheter body the temperature resistant sleeve having a polymeric body of material with a melting point which is substantially higher than the melting points of the first and second tubing segment, comprising: directing the first and second tubing segments together over the temperature resistant sleeve while heating the first and second tubing segments above their melting points but below the melting point of the polymeric body, so that the melting point of the material of the polymeric body is not attained to; whereby the segments flow together to bond the first and second tubing segments together and to the temperature resistant sleeve to provide a reinforced butt bond.
Claim 2
Independent Claim
128 words
A method of bonding first and second tubing segments together and to a temperature resistant sleeve to form a composite catheter body the temperature resistant sleeve having a polymeric body of material with a melting point which is substantially higher than the melting points of the first and second tubing segment, comprising: directing the first and second tubing segments together over the temperature resistant sleeve while heating the first and second tubing segments above their melting points but below the melting point of the polymeric body, so that the melting point of the material of the polymeric body is not attained to; whereby the segments flow together to bond the first and second tubing segments together and to the temperature resistant sleeve to provide a reinforced butt bond.
Claim 3
Dependent Claim
26 words
The method of claim 1, wherein the first and second tubing segments are placed within a capture tube while heating the first and second tubing segments.
Claim 4
Dependent Claim
27 words
The method of claim 2, wherein the capture tube, with the first and second tubing segments and the polymeric sleeve therein, is placed in a heating element.
Claim 5
Dependent Claim
19 words
The method of claim 2, wherein the first and second tubing segments are heated by applying hot air thereto.
Claim 6
Dependent Claim
15 words
The method of claim 1, wherein the polymeric sleeve includes a spirally wound reinforcement therein.
Claim 7
Dependent Claim
25 words
The method of claim 1, wherein the first and second tubing segments are heated to a temperature of between about 200° F. and 450° F.
Claim 8
Dependent Claim
19 words
The method of claim 1, wherein the polymeric sleeve has a melting point of at least about 700° F.
