Abstract

Several embodiments of a disposable surgical tool for quickly and easily connecting tubing to implantable components are disclosed. A method for using the novel tool for connecting tubing to components, such as a pump, a reservoir, a connector, etc., is also described.

Description

CROSS-REFERENCE To RELATED APPLICATIONS

This application claims the benefit of provisional patent application No. 60/660,442 filed Mar. 10, 2005; and of provisional patent application No. 60/660,491 filed Mar. 10, 2005.

TECHNICAL FIELD

The present invention relates to surgical devices and methods. More specifically, the present invention pertains to devices and methods for connecting tubing to components.

BACKGROUND

Certain surgical procedures, such as a penile implant, include the placement of a system of interconnected components within a body. Components in such systems may include a cylinder, reservoir, pump, etc. Some such components, such as a balloon, may be configured for selective inflation and/or deflation by an operator. Typically, a system may include an inflatable/deflatable component interconnected to a fluid-filled reservoir, a pump, and a valve assembly. During use, the pump may be actuated and fluid transferred from the reservoir into the component, causing the component to inflate. Later, a valve assembly may be operated deflating the component by transferring the fluid from the inflated component back into the reservoir.
An implantable system may include a multitude of tubing interconnecting several components. Typically, the tubing may be inserted into a strain relief component and the open end of the tubing connected to the component. In prior art examples, such as U.S. Pat. No. 4,651,721 to Mikulich et al. and U.S. Pat. No. 5,167,611 to Cowan, among others, a straight bore is extended through a strain relief and into the inflatable/deflatable component.
The points of connection between the tubing and the components may be a source of complication, such as leakage, disconnect, etc., and may also pose sterilization challenges in certain environments. Additionally, portability and handling of the connection tools for effecting the connections may also pose a challenge due to the weight and size of the connection tool.
Accordingly, there exists a need in the art for connection tools and methods which ease such surgical procedures.

SUMMARY

In one aspect, the present invention discloses a surgical device and method for connecting tubes to components, such as a pump, a reservoir, a connector, etc.
While multiple embodiments of the instant invention are disclosed, still other embodiments may become apparent to those skilled in the art. The following detailed description shows and describes illustrative embodiments of the present invention. As will be realized, the embodiment are capable of modifications in various aspects, all without departing from the spirit and scope of the instant invention. Accordingly, the drawings and detailed description are to be regarded as illustrative in nature and not restrictive.

FIGS. 2A-2C illustrate a method of using the tool of FIG. 1;
FIGS. 3A-3C illustrate different embodiments of a device of the present invention;

DETAILED DESCRIPTION

FIG. 1 illustrates a prior art device 10 for connecting tubing to a component. As shown, device 10 includes two arms or handles 12 and 14, tubing connecting portion 16 including jaws 17, and stop member 18 to prevent connecting portion 16 from closing all the way or to close only up to a predetermined position.
FIGS. 2A-2C illustrate a method for connecting two tubing segments or tubes to each other using a prior art device, such as device 10. The first step of the method is to place a collet over the tubing, such as sliding collet 22 onto tubing 20 as shown in FIG. 2A. FIG. 2B shows tubing connector 28 for connecting tubing segments 24 and 30 to each other at their respective open ends 34 and 38. Tubing connector 28 is shown having ports 36 and 40 through which tubing 24 and 30, respectively, will be connected. Tubing 24 includes collet 26 proximate open end 34, and tubing 30 includes collet 32 proximate open end 38. Next, open end 34 is slid over port 36 until open end 34 touches wall 42 in connector 28. Similarly, open end 38 of tubing 30 is pushed over port 40 until open end 38 also touches wall 42. Then collet 26 and 32 are slid over tubing 24 and 30 towards the edges of connector 28. Jaws 17 of tubing connecting portion 16 are placed around collet 26 and 32, as illustrated in FIG. 2C, and handles 12 and 14 of device 10 are squeezed together until closure stop 18 on handle 14 touches opposite handle 12. Thus tubing 24 and 30 are connected and device 10 removed.
Alternate embodiments of a device for connecting tubing to components or tubing connectors such as connector 28 are illustrated in FIGS. 3A-3C.
FIG. 3A illustrates device 300 in accordance with an embodiment of the present invention.

In accordance with an embodiment of the present invention, first and second elongate members 302 and 304 may be hingedly connected at distal edge 307 along their inside surface 310.
Top surface 314 may include recess 318 proximate of distal end 306. Recess 318 may extend into first and second elongate members 302 and 304 to first stop position 320 and thereafter extend towards distal end 306 from first stop position 320 to second stop position 322. The width of recess 318 may be slightly larger than the outside diameter of a tubing, such as tubing 20, so that the tubing may enter elongate members 302 and 304 through second stop position 322 on outside surface 312, slide through a collet housed proximate second stop position 322 within each of first and second elongate members 302 and 304, and exit first and second elongate members 302 and 304 on their inside surface 310. Also, having the width of recess 318 slightly larger than the outside diameter of a tubing may ease the removal of the tubing through top surface 314 after the tubing has been securely connected to a component.
Each of first and second elongate members 302 and 304 may also include opening 324 on inside surface 310. Opening 324 may be centered proximate the center of first stop position 320 and may be slightly larger than a collet so that the collet may be dispensed out of elongate members 302 and 304 through opening 324.

The width of recess 318 may be slightly larger than the outside diameter of a tubing, such as tubing 20, so that the tubing may enter elongate members 352 and 354 through second stop position 322 on outside surface 362, slide through a collet housed proximate second stop position 322 within each of first and second elongate members 352 and 354, and exit first and second elongate members 352 and 354 on their inside surface 360. Also, having the width of recess 318 slightly larger than the outside diameter of a tubing may ease the removal of the tubing through top surface 364 after the tubing has been securely connected to a component.
Each of first and second elongate members 352 and 354 may also include opening 324 on inside surface 360. Opening 324 may be centered proximate the center of first stop position 320 and may be slightly larger than a collet so that the collet may be dispensed out of elongate members 352 and 354 through opening 324.
FIG. 3C illustrates device 380 in accordance with a further embodiment of the present invention.
