Definitions

  • the present invention relates generally to medical devices and, more particularly, to connector assemblies for joining two pieces of medical tubing, e.g., catheters, wherein the connector assemblies are operable to provide strain relief to the catheter connection.
  • a typical implant procedure may involve implanting a drug infusion pump into a cavity or subcutaneous pocket in the body and delivering a drug, via a catheter(s), to an epidural space or intrathecal space of the spinal column or to a particular location within the brain.
  • a catheter assembly having two or more catheter sections, e.g., a thin-walled distal section (near the implantation site) and a thicker-walled proximal section (connected directly to the infusion pump), may be used to deliver the drug to the desired site.
  • the distal catheter section may be positioned in the desired location in the body and then connected to the proximal catheter section by use of a medical tubing connector.
  • connection may be made by inserting one end or prong of the connector into a lumen of one catheter section (e.g., the proximal section) and the other end of the connector into the lumen of the other catheter section (e.g., the distal section) and then sliding both catheter sections towards one another (toward the middle of the connector).
  • the proximal section may then be connected to the drug infusion pump. While adequate, difficulties have been encountered in the manufacture and use of such prior art medical connectors. For example, these connectors, which have been sized to fit within the lumens of the catheter tubing sections, are small and may be difficult to manipulate during implantation.
  • a connector assembly having a connector pin.
  • the connector pin includes: a first end portion, a second end portion, and a lumen extending between the first end portion and the second end portion; and a central portion located between the first end portion and the second end portion, wherein the central portion has an outer dimension that is larger than an outer dimension of both the first and second end portions.
  • the assembly also includes a tubular connector sleeve comprising a first end, a second end, and a passageway extending between the first end and the second end.
  • the passageway is stepped such that it has: a first diameter between the first end of the sleeve and a stop surface located in the passageway; and a second diameter between the stop surface and the second end of the sleeve, wherein the first diameter is greater than the second diameter.
  • a method of interconnecting sections of medical tubing includes inserting a first end portion of a connector pin into a first medical tube.
  • the connector pin includes: a second end portion, wherein a lumen extends between the first end portion and the second end portion; and a central portion located between the first and second end portions, wherein the central portion includes an outer dimension that is greater than an outer dimension of either of the first and second end portions.
  • the method also includes: inserting the second end portion into a second medical tube; sliding a tubular sleeve over the first and second medical tubes and the connector pin; and engaging a first lock portion located within a passageway of the sleeve with a second lock portion of the connector pin.

  • the connector sleeve 200 may be made of a flexible and resilient material operable to receive the catheters 60 and 70 and the connector pin 100 therein.
  • the connector sleeve 200 may provide not only secure coupling of the mating components, but also strain relief to the catheter ends.
  • the connector sleeve 200 may include a passageway 208 extending from a first end 204 of the sleeve to a second end 206.

  • the term “diameter” may be used to describe an effective diameter of any component of the present invention (e.g., sleeve, sleeve passageway, connector pin, lumen, and tubing section) whether it has a circular or non-circular cross-sectional shape, e.g., oval.
  • the first section 209 of the sleeve 200 may be defined by an inner surface 216.
  • the inner surface or wall 216 may include a lock portion, e.g., an inwardly extending protrusion 218.

This section of catheter may be inserted in a manner known to those skilled in the art. Before, during, or after proper placement of the distal section of the catheter 70 has been verified, a subcutaneous pump pocket may be prepared at the desired anatomical location within a patient's body. A proximal catheter section, e.g., catheter 60 of Figure 2, may then be tunneled from the distal catheter section to the pump pocket.
  • a proximal catheter section e.g., catheter 60 of Figure 2

  • a suture groove 202 is located over each side of the central portion 106, such that each catheter is effectively ligated by a suture.
  • the size of medical tubing connector assembly 50 may vary depending upon the size of the particular tubing to be connected.
  • the catheters 60 and 70 may have an undeflected lumen diameter of about 0.02 to about 0.03 inches
