## Abstract

In a general aspect, the techniques described herein relate to a medical device that includes a first elongated member that has an extruded outer jacket having an outer sidewall, where the extruded outer jacket includes a polymer material with a slip agent added to the polymer material.

## Claims

### Claim 1

A medical device comprising:
a first elongated member, the first elongated member including an outer jacket having an outer sidewall,
wherein the outer jacket includes a polymer material with a slip agent added to the polymer material.

### Claim 2 (depends on 1)

The medical device of claim 1, wherein the polymer material does not include PFAS.

### Claim 3 (depends on 1)

The medical device of claim 1,
wherein the first elongated member further includes a metallic wire disposed along an axis of the first elongated member, and
wherein the outer jacket is extruded around the metallic wire.

### Claim 4 (depends on 1)

The medical device of claim 1, further comprising:
a second elongated member having a lumen configured to receive the first elongated member, the slip agent reducing a frictional force between the second elongated member and the first elongated member when the first elongated member slides within the lumen of the second elongated member.

### Claim 5 (depends on 1)

The medical device of claim 1, wherein the slip agent includes a silicone oil.

### Claim 6 (depends on 1)

The medical device of claim 1, wherein the slip agent includes a fatty acid.

### Claim 7 (depends on 1)

The medical device of claim 1, wherein the slip agent includes a lecithin.

### Claim 8 (depends on 1)

The medical device of claim 1, wherein the slip agent includes a vegetable oil.

### Claim 9 (depends on 1)

The medical device of claim 1, wherein the slip agent is mixed into the polymer material before the polymer material is extruded to form the outer jacket.

### Claim 10 (depends on 9)

The medical device of claim 9, wherein the slip agent migrates from bulk material of the outer jacket to the outer sidewall of the outer jacket.

### Claim 11 (depends on 1)

The medical device of claim 1, wherein the slip agent migrates to the outer sidewall of the outer jacket after the polymer material is extruded to form the outer jacket.

### Claim 12 (depends on 1)

The medical device of claim 1, wherein the polymer material has a flexibility that increases by at least 10% as a temperature of the polymer material increases from 20° C. to 40° C.

### Claim 13

A method comprising:
applying a lubricant to an outer sidewall of a polymer outer jacket of a first elongated member, wherein the polymer does not include PFAS; and
inserting the first elongated member into a lumen of a second elongated member, wherein the lubricant reduces a frictional force between the second elongated member and the first elongated member when the first elongated member slides within the lumen of the second elongated member.

### Claim 14 (depends on 13)

The method of claim 13,
wherein the first elongated member further includes a metallic wire disposed along an axis of the first elongated member, and
wherein the outer jacket is extruded around the metallic wire.

### Claim 15 (depends on 13)

The method of claim 13, wherein the lubricant includes a silicone oil.

### Claim 16 (depends on 13)

The method of claim 13, wherein the lubricant includes a fatty acid.

### Claim 17 (depends on 13)

The method of claim 13, wherein the lubricant includes a lecithin.

### Claim 18 (depends on 13)

The method of claim 13, wherein the lubricant includes a vegetable oil.

### Claim 19 (depends on 13)

The method of claim 13, wherein the lubricant is mixed into the polymer as a migrating slip agent that migrates from bulk material of the outer jacket to the outer sidewall of the outer jacket before the polymer is extruded to form the outer jacket.

### Claim 20 (depends on 13)

The method of claim 13, wherein the polymer has a flexibility that increases by at least 10% as a temperature of the polymer increases from 20° C. to 40° C.
