Implantable medical device for improved placement in the body
View Patent ↗An implantable port includes a bottom portion having a needle-penetrable region running continuously along a majority of a perimeter of the implantable port. A method for customized suturing of an implantable port also includes creating a port pocket, and advancing a suture needle through the needle-penetrable region. The needle-penetrable region could be a self-sealing elastomer, such as silicone. The method could include the step of determining suture locations after the port pocket is created.
1. An implantable port for fluid access to a target site within a body, the implantable port comprising:
a housing defining an entry site for the administration, withdrawal, or exchange of fluids with the target site, the entry site comprising a septum; and
a bottom portion comprising a needle-penetrable region running continuously along a majority of a perimeter of the implantable port;
wherein the needle-penetrable region is configured to allow complete penetration by a suture needle to attach a suture, and
wherein the implantable port is devoid of any preformed suture holes.
2. The implantable port of claim 1 , wherein the needle-penetrable region comprises a self-sealing elastomer.
3. The implantable port of claim 1 , wherein the needle-penetrable region comprises a flexible polymer.
4. The implantable port of claim 1 , wherein the needle-penetrable region further comprises silicone.
5. The implantable port of claim 1 , wherein the needle penetrable region extends continuously along a cross-section of a bottom surface of the implantable port, the cross-section defined by a perimeter of the bottom surface.
6. The implantable port of claim 1 , wherein the bottom portion further comprises a continuous annular needle-penetrable perimeter region.
7. A method for customized suturing of an implantable port within a port pocket, the implantable port comprising a housing defining an entry site for the administration, withdrawal, or exchange of fluids with the target site, the entry site comprising a septum, and a bottom portion comprising a needle-penetrable region running continuously along a majority of a perimeter of the implantable port, wherein the needle-penetrable region is configured to allow complete penetration by a suture needle to attach a suture, and wherein the implantable port is devoid of any preformed suture holes, the method comprising:
creating the port pocket within the body of a patient;
placing the implantable port within the port pocket; and
advancing a suture needle through the needle-penetrable region and into tissue comprising the port pocket.
8. The method of claim 7 further comprising:
repeating the step of advancing a suture needle through the needle-penetrable region and into tissue comprising the port pocket a plurality of times.
9. The method of claim 8 further comprising:
creating multiple sutures adjacent to each other on the needle-penetrable region.
10. The method of claim 7 further comprising:
determining a suture location on the needle-penetrable region after creating the port pocket.
11. The method of claim 7 further comprising:
determining a plurality of suture locations on the needle-penetrable region after creating the port pocket.
12. The method of claim 7 , wherein the needle-penetrable region further comprises a self-sealing elastomer.
13. The method of claim 7 , wherein the needle-penetrable region further comprises a flexible polymer.
14. The method of claim 7 , wherein the needle-penetrable region further comprises silicone.
15. The method of claim 7 , wherein the needle-penetrable region extends continuously along a cross-section of a bottom surface of the implantable port, the cross-section defined by a perimeter of the bottom surface.
16. The method of claim 7 , wherein the bottom portion further comprises a continuous annular needle-penetrable perimeter region.
