Devices, Systems, and Methods Providing Body Lumen Access
First Claim
1. An implantable port device for providing access through a tissue wall of a lumen of a patient'"'"'s body, comprising:
- a body comprising a first end having a first opening and an opposed second end having a second opening, and a channel extending from between and operably connecting the first opening and the second opening;
a first retaining member extending radially from the first end of the body; and
a second retaining member spaced apart from the first retaining member, the second retaining member being closer than the first retaining member to the second end of the body, and extending radially from the second end of the body,wherein the first retaining member and the second retaining member are configured to cooperatively engage opposing sides of the tissue wall about edges of an aperture through the tissue wall to secure the body within the aperture.

Abstract
Devices and methods are provided which include access port devices for implantation through a tissue wall of a lumen of patient'"'"'s body and for containing electrical leads therein. An implantable port device includes a body with a first end having a first opening and an opposed second end having a second opening, and a channel extending from between and operably connecting the first opening and the second opening; a first retaining member extending radially from the first end of the body; and a second retaining member spaced apart from the first retaining member, the second retaining member being closer than the first retaining member to the second end of the body, and extending radially from the second end of the body. The first retaining member and the second retaining member are configured to cooperatively engage opposing sides of the tissue wall about edges of an aperture through the tissue wall to secure the body within the aperture.

26. A method of implanting an access port device in a patient in need thereof, comprising:
-
penetrating a lumenal tissue wall using a guidewire, forming an aperture therein; attaching an access port device to the guidewire; pulling the guidewire through the tissue wall in a manner effective to pull the access port into a position within the aperture of the tissue wall; detaching the guidewire from the access port device; and removing the guidewire from the lumen of the lumenal tissue wall. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33)

34. A kit for implanting an access port device in a tissue wall of a lumen of a patient'"'"'s body, comprising:
-
an access port device comprising; a body comprising a first end having a first opening and an opposed second end having a second opening, and a channel extending from between and operably connecting the first opening and the second opening; a first retaining member extending radially from the first end of the body; and a second retaining member spaced apart from the first retaining member, the second retaining member being closer than the first retaining member to the second end of the body, and extending radially from the second end of the body; a guidewire for penetrating the tissue wall and forming an aperture therein, and/or for inserting the access port device through the aperture formed in the tissue wall; and a dilator for enlarging the aperture formed in the tissue wall.
