Stabilized elongate implantable vascular access device
First Claim
1. A subcutaneous port for providing access to a body lumen, the port comprising in combination:
- an elongate body having a hollow interior extending between ends thereof;
a head adjacent one of said ends of said body;
said head including a chamber communicating with said hollow interior of said elongate body;
a septum coupled to and in contact with said head and adjacent said chamber, said septum adapted to be penetrated by a needle passing through the skin;
said elongate body adapted to be coupled, at least indirectly, to a body, lumen; and
a rigid wing affixed to and in contact with said elongate body and movably coupled to said elongate body, said wing having at least one tip, said tip having at least two positions including a first position and a second position relative to said body, said first position closer to said body than said second position.

Abstract
A vascular access port is described that is elongate in form. A distal end is coupled to a tube which leads into a body lumen. A proximal end has a head thereon with a septum which can be repeatedly penetrated by a needle and reseal, for repeated administration of medications or other compositions through the port and into the body of the patient. A wing is attached to the body that has two positions including a streamlined first position for implantation and a wider second position for stabilization of the port after implantation. A stay is preferably also provided to abut the wing when in the second position to keep the wing in the second position when fully deployed.

9. A method for reliably and repeatedly accessing a body lumen through a subcutaneous port, the method including the steps of:
-
providing a port having an elongate body having a hollow interior extending between ends thereof, a head adjacent one of the ends of the body, the head including a chamber communicating with the hollow interior of the elongate body, a septum coupled to and in contact with the head and adjacent the chamber, the septum adapted to be penetrated by a needle passing through the skin, the elongate body adapted to be coupled, at least indirectly, to a body lumen, and a rigid wing affixed to and in contact with the elongate body and movably coupled to the elongate body, the wing having at least one tip, the tip having at least two positions including a first position and a second position relative to the body, the first position closer to the body than the second position; forming an incision adjacent where the port is desired to be implanted; inserting the port into the desired position subcutaneously; and coupling a portion of the body at least indirectly to the body lumen to be accessed. - View Dependent Claims (10, 11, 24)

12. A method for reliably and repeatedly accessing a body lumen through a subcutaneous port, the method including the steps of:
-
providing a port having an elongate body having a hollow interior extending between ends thereof, a head adjacent one of the ends of the body, the head including a chamber communicating with the hollow interior of the elongate body, a septum coupled to the head and adjacent the chamber, the septum adapted to be penetrated by a needle passing through the skin, the elongate body adapted to be coupled, at least indirectly, to a body lumen, and a rigid wing affixed to the elongate body and movably coupled to the elongate body, the wing having at least one tip, the tip having at least two positions including a first position and a second position relative to the body, the first position closer to the body than the second position; forming an incision adjacent where the port is desired to be implanted; inserting the port into the desired position subcutaneously; and coupling a portion of the body at least indirectly to tie body lumen to be accessed, rotating the rigid wing by a pivoting motion from the first position to the second position; pushing on a portion of the elongate body on a side of the wing opposite the head through the skin to cause portions of the elongate body on a side of the wing opposite where pushing is occurring to be moved toward the skin; and passing a needle through the skin and into the septum within the head of the elongate body after the head has been raised for easy access by said pushing step.

13. A subcutaneous body lumen access port, comprising in combination:
-
an elongate body extending between a distal end and a proximal end; said elongate body including a hollow interior pathway extending substantially from said distal end to said proximal end; said elongate body having a length from said distal end to said proximal end and a width lateral to said length, said width less than said length; said proximal end including a septum adjacent thereto; said septum adapted to be penetrated by a needle to facilitate transfer of fluids between said hollow interior and the needle; said distal end adapted to be coupled to a body lumen in a manner facilitating transfer of fluids between said hollow interior pathway of said elongate body and the body lumen; and wherein a rigid wing is affixed to said elongate body and interposed between said proximal end and said distal end, said wing adapted to move from a first position to a second position with said elongate body having a narrower cross-section when said wing is in said first position than said second position and said wing having a greater cross-section than said proximal end when said wing is in said second position. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
