Abstract

Methods and products for treating capsular contractures of breast implants including (1) obtaining a platelet-rich plasma (PRP) or platelet-rich fibrin (PRF) fraction from a patient who exhibits capsular contracture of a breast implant; and (2) applying the PRP or PRF fraction to said capsular contracture, thereby relaxing the capsular contracture.

Claims (20)

1 . A method for treating capsular contracture of breast implant comprising (1) obtaining a platelet-rich plasma (PRP) fraction from a patient who exhibits capsular contracture of a breast implant; and (2) applying the PRP fraction to said capsular contracture, thereby relaxing the capsular contracture.

2 . The method of claim 1 , wherein the PRP fraction is applied to the capsular contracture by injecting the PRP fraction adjacent to the capsular contracture and spreading the injected PRP fraction under a patient's skin by manipulation to promote relaxation of the capsular contracture.

3 . The method of claim 2 , wherein acoustic sound waves or ultrasound waves are applied during the manipulation.

4 . The method of claim 2 , wherein the PRP fraction is a first PRP fraction and wherein a subsequent PRP fraction is obtained from the patient and the subsequent PRP fraction is applied to the capsular contracture by applying the subsequent PRP fraction to the patient's skin adjacent to said capsular contracture and inducing transdermal absorption of the subsequent PRP fraction into the skin through pulsed electrical currents, thereby relaxing the capsular contracture.

5 . The method of claim 1 , wherein applying the PRP fraction to said capsular contracture includes applying the PRP fraction to a patient's skin adjacent to said capsular contracture and inducing transdermal absorption of the PRP fraction into the skin with pulsed electrical currents, thereby relaxing the capsular contracture.

6 . The method of claim 5 , wherein a device placed proximally to the skin provides the pulsed electrical currents.

7 . The method of claim 5 , wherein the PRP fraction is a first PRP fraction and wherein a subsequent PRP fraction is obtained from the patient and the subsequent PRP fraction is applied to the capsular contracture by applying the subsequent PRP fraction to the skin by injecting the subsequent PRP fraction adjacent to the capsular contracture and spreading the injected subsequent PRP fraction under the skin by manual manipulation to promote relaxation of the capsular contracture.

8 . The method of claim 7 , wherein acoustic sound waves or ultrasound waves are applied during the manipulation.

9 . The method of claim 5 , wherein the PRP fraction is a first PRP fraction and wherein a subsequent PRP fraction is obtained from the patient and the subsequent PRP fraction is applied to the capsular contracture by applying the subsequent PRP fraction to skin adjacent to said capsular contracture and inducing the transdermal absorption of the subsequent PRP fraction into the skin through pulsed electrical currents, thereby relaxing the capsular contracture.

10 . The method of claim 1 , wherein the PRP fraction is a first PRP fraction and wherein a subsequent PRP fraction is obtained from the patient, and wherein a subsequent application of PRP is applied to the capsular contracture at least one week after the first PRP fraction is applied to the capsular contracture.

11 . The method of claim 1 , wherein the PRP fraction is a first PRP fraction and wherein a subsequent PRP fraction is obtained from the patient, and wherein a subsequent application of PRP is applied to the capsular contracture within a 25 day period of the first PRP fraction.

12 . The method of claim 1 , wherein the capsular contracture exhibits a Baker grade of 3-4 prior to application of the PRP fraction, and inhibition of the capsular contracture by at least one level Baker grade occurs within 30 days of the application.

13 . The method of claim 1 , wherein the PRP fraction is applied by injection in a first treatment session and transdermally in at least one subsequent treatment session.

14 . The method of claim 1 , wherein successive treatment sessions are separated by one week to 25 days.

15 . The method of claim 1 , wherein myofibroblasts and/or immune cells are obtained from the capsular contracture, and a severity of the capsular contracture is based on data determined from a biopsy of the myofibroblasts and/or immune cells.

16 . The method of claim 1 , wherein myofibroblasts and/or immune cells are obtained from the capsular contracture, and a treatment volume of the PRP fraction is determined based on data determined from a biopsy of the myofibroblasts and/or immune cells.

17 . The method of claim 1 , wherein fibrinogen and/or fibrin are obtained from fluid surrounding the capsular contracture, and a severity of the capsular contracture is based on data determined based on characteristics of the fibrinogen and/or fibrin.

18 . The method of claim 1 , wherein fibrinogen and/or fibrin are obtained from fluid surrounding the capsular contracture, and a treatment volume of the PRP fraction is determined based on data determined from a biopsy of the fibrinogen and/or fibrin.

19 . The method of claim 1 , wherein an application location for the PRP fraction is determined based on ultrasound data of the capsular contracture.

20 . The method of claim 1 , wherein a location at which said PRP fraction is applied to said capsular contracture is based on ultrasound data.
