Description
- This application is a divisional of U.S. application Ser. No. 10/127,853, filed on Apr. 23, 2002, which is herein referenced in its entirety.
- This invention relates to medical device connectors used for connecting medical tubing. More particularly, the invention is directed to a medical connector for connecting sections of a catheter.
- In numerous medical applications it becomes necessary to connect one section of tubing to another. In such situations it is important that the connection be secure so that it will not pull apart and that there be no leakage of fluid at the site of the connection. This is especially critical in applications where the tubing sections are implanted in the human body.
- U.S. Pat. No. 5,405,339, which is incorporated herein by reference, teaches connector for connecting sections of medical tubing and a method for using the connector. The connector has an enlarged middle portion between first and second end portions. The end portions have a smaller diameter than the enlarged middle portion and are adapted to be inserted into the ends of the medical tubing sections. The connector can be grasped at the enlarged middle portion, thus simplifying the process of inserting the end portions into the tubing sections. Additionally, the opposing edges of the enlarged middle portion act as tubing stop surfaces that provide a positive indication that the connector is properly aligned.
- While the invention described in U.S. Pat. No. 5,405,339 has solved numerous difficulties in the manufacture and use of the prior art medical devices, there is still certain areas for further improvement. For example, FIG. 3 of U.S. Pat. No. 5,405,339 teaches an addition of a circumferential suture groove in the surface of the enlarged middle portion that can only be used as a place at which the catheter may be anchored by suturing it to surrounding tissue if the connector is used without a strain relief. Col. 5, lines 37-43.
- It would be desirable to provide a connector that provides a place at which the catheter may be anchored by suturing it to surrounding tissue, while at the same time providing a strain relief. It would also be desirable to provide a connector that provides stronger connections with greater useful life, and which is simple to use.
- In accordance with the present invention there is disclosed an implantable medical device comprising a connector for connecting sections of medical tubing and a method for using the connector. The connector is shaped in a manner that solves the problems associated with prior art connectors and methods of connecting medical tubing.
- More specifically, the present invention comprises a connector for medical tubing, the connector defining a fluid passageway, the connector having a first end, a first intermediate portion, a middle portion, a second intermediate portion, and a second end. The middle portion located between the first intermediate portion and the second intermediate portion. The end is adapted to fit inside a proximal connector-receiving portion of a proximal medical tube, the second end is adapted to fit inside a distal connector-receiving portion of a distal medical tube. The connector also has a least a first protrusion and a second protrusion projecting from the connector, wherein a first protrusion is located between the first end and the first intermediate portion, and the second protrusion is located between the second intermediate portion and the second end. The connector also includes a first tubular strain relief having an extending first portion that extends past the first end of the connector and is adapted to fit over a proximal connection section of a proximal medical tube, and a second tubular strain relief having an extending second portion that extends past the second end of the connector is and adapted to fit over a distal connection section of a distal medical tube. When the first end of the connector is inserted into the proximal connector-receiving portion a first interlock fit is formed therebetween, and when the second end of the connector is inserted into the distal connector-receiving portion a second interlock fit is formed therebetween. The result is a fluid tight connection between the proximal connector-receiving portion and the distal connector-receiving portion, and wherein at least the middle portion of the connector is exposed. In one embodiment, the first intermediate portion can include a first lip, and the second intermediate portion can include a second lip. Thus, when the first tubular strain relief fits over the first lip of the first intermediate portion, a third interlock fit is formed therebetween. Further, when the second tubular strain relief fits over the second lip of the second intermediate portion, a fourth interlock fit is formed therebetween.
- In one embodiment, the middle portion further comprises a suture receiving portion. The suture receiving portion has a suitable structure that can be anchored by suturing to surrounding tissue or fascia of a patient. For example, but not by way of limitation, the suture receiving structure can have a suture receiving groove or hole. Preferably, the suture receiving portion has at least two locations to receive sutures so as to reduce rotation of the connector.
- In one embodiment, the extending first portion of the first tubular strain relief is more flexible than a remainder of the first tubular strain relief and/or the extending second portion of the second tubular strain relief is more flexible than a remainder of the second tubular strain relief.
- In one embodiment, the extending first portion of the first tubular strain relief tapers to a smaller outside diameter as it extends away from the first end of the connector and/or the extending second portion of the second tubular strain relief tapers to a smaller outside diameter as it extends away from the second end of the connector.
- In one embodiment, at least the first intermediate portion of the connector is exposed and/or at least the second intermediate portion of the connector is exposed. Thus, the first intermediate portion and/or the second intermediate portion of the connector can be used as a convenient place to anchor the catheter to the tissue or fascia of a patient.
- In one embodiment, the connector comprises a metal or metal alloy.
- In one embodiment, the first tubular strain relief fits over the proximal connection section and a proximal fit is formed therebetween.
- In one embodiment, the second tubular strain relief fits over the distal connection section and a distal fit is formed therebetween.
- In one embodiment, the middle portion comprises a suture receiving portion. The suture receiving portion has a suitable structure that can be anchored to the tissue or fascia of a patient. For example, but not by way of limitation, the suture receiving structure can have a suture receiving groove or hole. Preferably, the suture receiving portion has at least two locations to receive sutures so as to reduce rotation of the connector.
- In one embodiment, the present invention includes an implantable medical device comprising a proximal catheter having a proximal connection section, the proximal connection section having a proximal connector-receiving portion, and a distal catheter having a distal connection section, the distal connection section having a distal connector-receiving portion. The implantable medical device also has a connector between the proximal catheter and the distal catheter, the connector defining a fluid passageway, the connector having a first end, a first intermediate portion, a middle portion, a second intermediate portion, and a second end. The middle portion is located between the first intermediate portion and the second intermediate portion. The first end is adapted to fit inside the proximal connector-receiving portion, the second end is adapted to fit inside the distal connector-receiving portion. There is also at least a first protrusion and a second protrusion projecting from the connector, wherein the at least first protrusion is located between the first end and the first intermediate portion, and the second protrusion is located between the second intermediate portion and the second end. The invention further has a first tubular strain relief having an extending first portion that extends past the first end of the connector and fits over the proximal connection section, and a second tubular strain relief having an extending second portion that extends past the second end of the connector and fits over the distal connection section. Thus, when the first end of the connector is inserted into the proximal connector-receiving portion a first interlock fit is formed therebetween, and when the second end of the connector is inserted into the distal connector-receiving portion a second interlock fit is formed therebetween. The result is a fluid tight connection between the proximal catheter and the distal catheter, and wherein at least the middle portion of the connector is exposed. Since the middle portion of the connector is exposed, it can be anchored by suturing to surrounding tissue or fascia of a patient. The connector of this embodiment can have any or all combination of additional features recited in the preceding paragraphs.
