Portal assembly
First Claim
1. A portal assembly for connecting to a catheter comprising:
- a port with a first resealable septum;
a first tube extending from the port, the first tube sized to be received inside the catheter;
wherein the port defines a plurality of suture holes, each suture hole having a first cylindrical passage, each suture hole having a lead-in sized larger than the first cylindrical passage and tapering to the first cylindrical passage; and
wherein the port further defines a plurality of depressions, each depression positioned adjacent one of the suture holes at an end opposite to an end defining the lead-in of each suture hole.

Abstract
A portal assembly includes a port with at least one resealable septum, and a tube extending from the port with the tube being sized to be received inside a catheter, an angled surface surrounding the tube wherein the angled surface diverges away from the tube in a direction away from the port, and sleeve structure for forcing the end of the catheter into the angled surface, thereby forcing the end of the catheter radially inwardly toward the tube and forming a thickened portion adjacent the end of the catheter to seal and hold the catheter. In a dual port construction, the outlet tube are parallel to one another at their distal ends, and the sleeve structure forces the end of the catheter into the angled surface, thereby forcing the end of the catheter radially inwardly toward the tubes and forming a thickened portion adjacent the end of the catheter to seal and hold the catheter and to prevent cross-talk between lumens of a dual lumen catheter.

4. A portal assembly for connecting to a catheter comprising:
-
a port with a first resealable septum; a first tube extending from the port, the first tube sized to be received inside the catheter; and wherein the port defines an internal chamber, the septum permitting access to the internal chamber, the first tube in fluid communication with the internal chamber, the internal chamber including a bottom surface facing opposite the septum wherein the bottom surface is defined by a complex curve including a first large radius defining a central portion and second smaller radius defining a periphery around the central portion. - View Dependent Claims (5, 6)

7. A portal assembly comprising:
-
a port with a first resealable septum and a second resealable septum, wherein the port includes first and second rings, the first ring surrounding the first septum, the second ring surrounding the second septum, the first ring having a first continuous portion having a cross-section defined by a first height projecting upward around the first septum, the second ring having a second continuous portion having a cross-section defined by a second height projecting upward around the second septum, the first height differently sized from the second height; a first tube extending from the port; and a second tube extending from the port. - View Dependent Claims (8, 9, 10, 11)
