11. 11 . The system of claim 1 , wherein the expandable member further comprises an anti-infection material.
12. 12 . (canceled)
13. 13 . The system of claim 1 , wherein the expandable member is self-sealing.
14. 14 . The system of claim 1 , wherein the expandable member comprises an anti-bleeding and anti-coagulation material.
15. 15 . A method comprising: inserting a distal portion of an electrical lead of a medical device system into vasculature of a patient, wherein the medical device system comprises: an implantable medical device electrically connected to the electrical lead; an expandable member comprising: a first portion defining an inner volume; and a second portion connected to a proximal end of the first portion; navigating the distal portion of the electrical lead to a target location within the vasculature of the patient; implanting the distal portion of the electrical lead in tissue at the target location; disposing the implantable medical device and an excess portion of the electrical lead within the inner volume of the expandable member; disposing the second portion of the expandable member over at least a part of the first portion of the expandable member; and delivering electrical therapy to the tissue at the target location through the electrical lead.
16. 16 . The method of claim 15 , wherein reducing the length of the electrical lead to the desired length comprises: determining the desired length and the excess portion of the electrical lead; securing the excess portion of the electrical lead into a storage configuration; and storing the excess portion of the electrical lead in the inner volume of the expandable member in the storage configuration.
17. 17 . The method of claim 15 , wherein the expandable member isolates the implantable medical device and the excess portion of the electrical lead from the tissue of the patient.
18. 18 . The method of claim 15 , wherein disposing the implantable medical device and the excess portion of the electrical lead within the inner volume of the expandable member comprises rolling the expandable member over the implantable medical device from a distal end of the implantable medical device to a proximal end of the implantable medical device.
19. 19 . The method of claim 15 , wherein disposing the second portion of the expandable member over the first portion of the expandable member comprises: twisting the second portion relative to the first portion; and roll the second portion over the first portion from the proximal end of the first portion towards a distal end of the first portion.

TECHNICAL FIELD This disclosure relates to medical device systems and, more particularly, to medical device systems for delivery of electrical stimulation therapy. BACKGROUND In some situations, medical professionals may insert an implantable medical lead into the body of the patient to deliver various therapies. In some examples, the implantable medical leads may be temporary and may be removed from the patient after a period of time. In some examples, with respect to cardiac-related issues, a medical professional may insert a type of implantable medical lead also referred to as a temporary pacing lead into a heart of the patient and deliver temporary cardiac pacing to the heart. SUMMARY The devices, systems, and techniques of this disclosure generally relate to managing movement of an implantable medical lead within a patient. In some examples, the implantable medical lead may have an excess portion that may be placed near an implantable medical device connected to the implantable medical lead. A clinician may need to control movement of the implantable medical lead within the patient. In some examples, the clinician may need to remove the implantable medical device and the implantable medical lead from the patient. This disclosure describes devices, systems, and techniques for managing movement of the implantable medical lead within the patient and devices, systems, and techniques for facilitating removal of the implantable medical lead from the patient. In an example, the disclosure describes a system comprising: an electrical lead; an implantable medical device, wherein the electrical lead is configured to be electrically connected to the implantable medical device, and wherein the implantable medical device is configured to deliver an electrical therapy to tissue of a patient via the electrical lead; and an expandable member configured to be disposed over the implantable medical device and an excess portion of the electrical lead, the expandable member comprising: a first portion defining an inner volume configured to retain the implantable medical device and the excess portion of the electrical lead; and a second portion connected to a proximal end of the first portion, the second portion configured to be disposed over at least a part of the first portion of the expandable member, wherein the expandable member is configured to control a length of the electrical lead within vasculature of the patient.
