Abstract

An article and method are presented wherein an implant member is provided that is expandable in at least one direction, the implant adapted for use within an area adjacent vocal folds of a patient, the implant member comprising two or more segments, and a subcutaneous access port providing access for injection of a bulking agent into the implant member.

Claims (23)

1. An article, comprising:

an implant member that is expandable in at least one direction;

the implant member comprising two or more segments, the two or more segments being adjacent to one another; and

two or more subcutaneous access ports for providing access for adjusting a mechanical stabilization mechanism within the implant member,

wherein a horizontal slice of the implant is wider at one end and narrower at the other end and a vertical slice is consistent along its length,

wherein the two or more segments are independently adjustable, and

wherein the implant member is adapted to support the vocal folds of a patient.

2. The article of claim 1 , wherein the mechanical stabilization mechanism consists of a spring-based support system.

3. The article of claim 1 , wherein the mechanical stabilization mechanism consists of a support system which is expandable by adjusting pressure, temperature, or addition of a fluid.

4. The article of claim 1 , wherein the implant member is made of a material that has an elastic limit beyond which the implant cannot expand.

5. The article of claim 1 , further comprising one or more channels between the two or more segments.

6. An article, comprising:

an implant member that is expandable in at least one direction, the implant adapted for use within an area adjacent vocal folds of a patient;

the implant member comprising two or more adjacent segments, the two or more segments being linked to each other at a minimum of one connection point; and

two or more subcutaneous access ports providing access for injection of a bulking agent into the implant member,

wherein each of the two or more adjacent segments are independently fillable,

wherein the two or more segments are independently fillable,

wherein the two or more subcutaneous access ports comprise a tubing pathway and a control mechanism connected to each of the two or more segments.

7. A method of implanting a vocal cord bulking system, comprising:

inserting an implant member with two or more adjacent segments adjacent vocal folds of a patient, wherein the two or more adjacent segments are independently adjustable;

inserting two or more subcutaneous access ports to access contents of the implant member through a neck of the patient; and

filling, draining, or otherwise adjusting the implant member through the subcutaneous access port to encourage improved phonation.

8. The method of claim 7 , further comprising adjusting the viscosity of bulking agents to meet a specific frequency response.
