Composite catheter stabilizing devices, methods of making the same and catheter extracting device
First Claim
1. A composite catheter stabilizing device useful for anchoring catheter to subcutaneous tissue, comprising:
- (a) a cuff having a first edge and a second edge, the cuff being configured for positioning around a catheter;
(b) a first end piece having an internal surface defining a tubular opening extending therethrough and an external surface tapered from a first side abutting the first edge of the cuff toward a second side, the first side having a generally annular cross section and a diameter which is substantially the same as an outer diameter of the cuff when the cuff is positioned around a catheter; and
(c) a second end piece having an internal surface defining a tubular opening extending therethrough and an external surface tapered from a first side abutting the second edge of the cuff toward a second side, the first side having a generally annular-cross section and a diameter which is substantially the same as an outer diameter of the cuff when the cuff is positioned around a catheter, wherein the second sides of the first and second end pieces are configured for receiving a catheter in facing engagement, and the first and second end pieces are configured to conform to an external surface of a catheter in facing engagement for facilitating smooth movement of a catheter through subcutaneous tissue, wherein an internal diameter of the composite catheter stabilizing device is dimensioned to be substantially the same as an external diameter of a catheter for enabling the composite catheter stabilizing device to be affixed to and to conform to an external surface of the catheter and to be capable of moving through subcutaneous tissue without detaching from a catheter in order to subcutaneously anchor a catheter in subcutaneous tissue.

Abstract
A composite catheter stabilizing device, a catheter assembly including such a stabilizing device and a device for removing a catheter assembly are provided. The stabilizing device includes a cuff having a first and second edge which is configured to be positioned around a catheter. The device further includes a first and second end piece. The first and second end pieces have internal surfaces defining tubular openings which extend through the end pieces. The first and second end pieces are tapered from first sides which abut the edges of the cuff to second sides and the second sides of the end pieces are configured for receiving a catheter in facing engagement. The device for removing a catheter assembly includes a handle and a head having an external gripping surface which is sized for inserting into a lumen of a catheter assembly having a tissue ingrowth cuff for gripping an internal surface of the catheter assembly within the cuff and dislodging the cuff from surrounding tissue.

6. A composite catheter stabilizing device useful for anchoring a catheter to subcutaneous tissue, comprising:
-
(a) a unitary base having an internal surface defining a tubular opening extending therethrough and having a first end piece, a second end piece, and an annular central portion positioned between the first and second end pieces, wherein the first end piece has an external surface tapered from a first side having an outer diameter toward a second side, the second end piece has an external surface tapered from a first side having an outer diameter to a second side and the internal surface configured for conforming to an external surface of a catheter in facing engagement, wherein an internal diameter of the unitary base device is dimensioned to be substantially the same as an external diameter of a catheter for enabling the unitary base to be affixed to and conform to an external surface of the catheter; (b) a cuff having a first edge abutting the first side of the first end piece and a second edge abutting the first side of the second end piece, the cuff having an outer diameter which is substantially the same as the outer diameter of the first side of the first end piece and as the outer diameter of the first side of the second end piece and being configured for positioning around the central portion of the base, wherein the base is configured for facilitating smooth movement of a catheter through subcutaneous tissue, and wherein the composite catheter stabilizing device is capable of moving through subcutaneous tissue without detaching from a catheter in order to subcutaneously anchor a catheter in subcutaneous tissue.
