Catheter Securement Device

Abstract

A coupler is configured to connect a first tubular vessel to an aperture in a second tubular vessel. The coupler includes one or more radially extending members and a substantially nonmetallic tubular member. The substantially nonmetallic tubular member include an outer wall, an inner wall defining a lumen having an open distal end and an open proximal end, and a circumferential ridge encircling the outer wall, the radially extending members extending from the distal end of the tubular member. A method of fabricating a coupler the method including fabricating radially extending members; placing the radially extending members within a mold; injecting a material into the mold; allowing the material to cure to form the c coupler; and removing the coupler from the mold. The coupler includes a tubular member having an outer wall, an inner wall defining a lumen having an open distal end and an open proximal end, and a circumferential ridge encircling the outer wall. The radially extending members extend from the distal end of the tubular member.

1 - 20 . (canceled)  
   
   
       21 . A catheter securement device comprising: 
 a tubular stem having a channel passing between a first end having a first opening and a second end having a second opening, the channel having an inner surface having a first diameter and the tubular stem having an outer surface having a second diameter, and a metallic strain relief positioned within the stem;    an outer ridge positioned around the outer surface of the stem having an outer surface having a third outer diameter and being connected to the stem by a proximal edge and a distal edge, the third outer diameter and the proximal edge and the distal edge extending outwardly from the stem to the third outer diameter; and    a tubular connecting member extending from the outer ridge, having a second channel passing between a first end having a first opening and a second end having a second opening, the second channel having an inner surface of a fourth diameter and the connecting member having an outer surface of a fifth diameter, and the first end of the tubular connecting member being connected to the second end of the tubular stem.    
   
   
       22 . The catheter securement device of  claim 21 , wherein the metallic strain relief comprises a superelastic material.  
   
   
       23 . The catheter securement device of  claim 21 , wherein the outer ridge further comprises a metallic ring having at least a portion of the ring positioned within the outer ridge between the outer surface and the stem.  
   
   
       24 . The catheter securement device of  claim 23 , wherein the metallic ring comprises a superelastic material.  
   
   
       25 . The catheter securement device of  claim 21 , further comprising at least one inner ridge extending inwardly from either or both of the first channel in the tubular stem or the second channel in the connecting member, the inner ridge having an inner diameter less than the inner diameter of the channel from which it extends.  
   
   
       26 . The catheter securement device of  claim 25 , wherein the inner ridge comprises a flap or valve.  
   
   
       27 . The catheter securement device of  claim 21 , wherein the device comprises a single molded piece.  
   
   
       28 . The catheter securement device of  claim 21 , wherein the tubular connecting member further comprises a ring.  
   
   
       29 . The catheter securement device of  claim 28 , wherein the ring extends around the second channel between the inner diameter and the outer diameter of the channel.
