IMPLANTABLE MEDICAL DEVICE FOR IMPROVED PLACEMENT AND ADHERENCE IN THE BODY
A medical device comprises a flexible member that can be adhesively attached to a housing of the medical device, allowing implantation of the medical device into a body through an incision of reduced size. The flexible member can be attached to the housing either before or after implantation into the body. The flexible member comprises suture locations, including a permeable membrane or a suture hole, for suturing the medical device to tissue of the body. The suture holes can be filled with a substance penetrable by a suture needle, to minimize tissue ingrowth before or after suturing.
1 . A system comprising:
a vascular access port comprising a housing, a needle entry site, a surface opposite the needle entry site, and a needle-penetrable member configured to be sutured to a subcutaneous tissue; wherein the needle-penetrable member varies in thickness along the surface opposite the needle entry site, and the needle-penetrable member traverses the surface opposite the needle entry site;
a catheter to operatively couple to the vascular access port; and
at least one insertion tool.
2 . The system of claim 1 , wherein the needle-penetrable member is configured to couple with the housing.
3 . The system of claim 1 , wherein the vascular access port and the catheter are in fluid communication and are both configured for an administration, withdrawal, or exchange of fluids.
4 . The system of claim 1 , wherein the at least one insertion tool comprises any of the following: a suture, a syringe, or an insertion tool configured to create a pocket in the subcutaneous tissue.
5 . The system of claim 1 , wherein the needle-penetrable member is configured to stabilize placement of the vascular access port within the subcutaneous tissue.
6 . The system of claim 1 , wherein the needle-penetrable member is configured to stabilize the vascular access port within a pocket in the subcutaneous tissue when sutured to the subcutaneous tissue.
7 . The system of claim 1 , wherein the vascular access port further comprises a septum coupled to the needle entry site.
8 . The system of claim 1 , wherein the system further comprises a connection means configured to operatively couple the vascular access port and the catheter.
9 . The system of claim 7 , wherein the vascular access port, the catheter, the at least one insertion tool, and the connection means are configured to be packaged together as a kit.
10 . The system of claim 1 , wherein the needle-penetrable member is configured to flex during movement of the subcutaneous tissue.
11 . The system of claim 1 , wherein the needle-penetrable member is configured to enhance manipulation or placement of the vascular access port relative to the subcutaneous tissue.
12 . A system comprising:
an access port comprising a housing, a housing bottom surface, an entry site, and a needle-penetrable member comprising a region of variable thickness extending along the housing bottom surface, wherein the needle-penetrable member does not contact the entry site, and at least a portion of the needle-penetrable member is configured to be sutured to a subcutaneous tissue;
a catheter; and
a connection means configured to operatively couple the access port and the catheter.
13 . The system of claim 12 , wherein the access port is a venous access port.
14 . The system of claim 12 , wherein the access port is configured to be in fluid communication with the catheter.
15 . The system of claim 14 , wherein the access port and the catheter are configured for the administration, withdrawal, or exchange of fluids.
16 . The system of claim 12 , wherein the needle-penetrable member is configured to stabilize placement of the vascular access port within the subcutaneous tissue.
17 . The system of claim 12 , wherein the needle-penetrable member is configured to stabilize the access port within a pocket in the subcutaneous tissue when sutured to the subcutaneous tissue.
18 . The system of claim 12 , wherein the access port further comprises a septum coupled to the entry site.
19 . The system of claim 12 , wherein the needle-penetrable member is configured to flex during movement of the subcutaneous tissue.
20 . A system comprising:
a port comprising a housing, a needle entry site, a surface opposite the needle entry site, and a needle-penetrable member configured to be sutured to a subcutaneous tissue; wherein the needle-penetrable member varies in thickness along the surface opposite the needle entry site, and the needle-penetrable member traverses the surface opposite the needle entry site;
a catheter;
a connection means configured to operatively couple the port and the catheter; and
an insertion device.
21 . The system of claim 20 , wherein the needle entry site is in fluid communication with the catheter.
22 . The system of claim 20 , wherein the system is configured to be packaged as a kit.
23 . The system of claim 22 , wherein the kit further comprises written instructions on a method of using the port and the catheter.
24 . The system of claim 20 , wherein the port further comprises a septum configured to fluidly seal the needle entry site.
25 . The system of claim 20 , wherein the insertion device is configured to create a pocket in the subcutaneous tissue.
26 . The system of claim 20 , wherein the system further comprises a suture, a syringe, or a suture and a syringe.
27 . The system of claim 20 , wherein the needle-penetrable member is configured to stabilize placement of the port within the subcutaneous tissue.
28 . The system of claim 20 , wherein the needle-penetrable member is configured to stabilize the access port within a pocket in the subcutaneous tissue when sutured to the subcutaneous tissue.
29 . The system of claim 20 , wherein the needle-penetrable member is configured to flex during movement of the subcutaneous tissue.
