Definitions
- the present invention relates to a method of lining a body cavity and to a lining device for lining a body cavity.
- US Patent No. 5236423 describes the eversion of a liner into a body cavity and the subsequent insertion of an endoscope within the liner.
- liners comprise a single walled tube of flexible material. Opposite ends of the liner are secured in position and fluid is pumped between these opposite ends to cause the liner to evert.
- US Patent No. 5458573 discloses a toposcopic dilatation catheter system utilizing a dilatation balloon in combination with an everting tube in a miniature catheter of a scale sufficiently small to negotiate a blood vessel for therapeutic as well as diagnostic purposes.
- the catheter system utilizes a primary catheter shaft provided with multiple lumen or passageways extending the length thereof.
- the dilatation balloon lumen provides access to a balloon carried at the distal end of the primary catheter shaft.
- the dilatation balloon may be expanded as required to aid in advancing the catheter system to the site requiring therapy.
- a secondary catheter tube is coaxially carried within the primary catheter shaft.
- the leading end of the secondary catheter tube includes an everting tube which everts from the leading end of the primary catheter shaft.
- the everting tube advances under fluid pressure in advance to the leading end of the primary catheter shaft.
- An object of one embodiment of the invention is to provide an improved arrangement for performing catheterisation.
- a method of facilitating the insertion of an instrument into a body cavity including providing a lining device comprising an eversible chamber and a liner connected thereto having a line of weakness therealong, applying fluid pressure to cause the chamber to evert and advance into the cavity such that the chamber carries the liner into the cavity so that the liner provides a passage within the cavity for the instrument, inserting the instrument into the passage and the cavity, and subsequently splitting the liner along the line of weakness to remove the liner from the instrument whilst the instrument remains in the cavity.
- the cavity may be a body cavity of an inanimate object, including an excised or artificial human or animal body part.
- the cavity may also be a cavity of the human or animal body, such as the urethra or colon.
- the chamber has a closed end for facilitating the application of fluid pressure.
- a method of facilitating the insertion of an instrument into a body cavity including providing a lining device comprising an eversible chamber and a liner connected thereto, applying fluid pressure to the chamber to cause the chamber to evert and advance into the cavity such that the chamber carries the liner into the cavity so that the liner provides a passage on the exterior of the chamber within the cavity, reducing the fluid pressure applied to the chamber to cause deflation of the chamber, inserting the instrument into the cavity through the passage, the liner being expandible, such that the passage has an external diameter approximately equal to the internal diameter of the cavity.
- deflation of the chamber may be caused by applying negative pressure or suction to the chamber.
- Figure 2 is a side elevational view of an everted lining device in accordance with an embodiment of the invention.
- Figure 4A is a cross-section taken along the line B-B of Figure 4.
- FIG. 10 shows the urethra after removal of the lining device.
- like elements are generally designated with the same reference sign.
- a lining device is shown in its everted state generally at 10.
- the lining device 10 comprises a chamber 12 that is closed at one end 14.
- the chamber 12 extends longitudinally in its everted state.
- a liner 16 is connected along its length to the chamber 12, for example by welding or any other suitable form of connection at 17.
- the chamber 12 is formed from flexible material such as latex or polyurethane.
- the liner 16 may be formed from the same flexible material as the chamber 12.
- the liner 16 may be integrally formed with the chamber 12 or may be formed separately and subsequently attached thereto.
- the liner 16 is open at its first end 22, proximate the closed end 14 of the chamber 12, and the liner 16 is also open at its second end 24, proximate the holding container 18.
- the liner 16 forms an open-ended elongate tube along which a part, such as a catheter or other medical instrument can pass.
- Figures 4 and 4A show a catheter 26 passing through the liner 16.
- Figures 2,3 and 4 show the lining device 10 in its everted state.
- the lining device 10 may be assembled by attaching the tubular lining 16 to the chamber 12 (when in the everted state as shown in Figures 2 and 3) and welding the liner 16 by a single longitudinal weld or adhesive 17 to the chamber 12, leaving the first and second ends 22,24 of the liner 16 open.
- the liner 16 may be formed such that it fits around the circumference of the chamber 12 and slides over the chamber 12. The liner 16 is then fixed to the chamber 12 by a weld or adhesive.
- the lining device 10 is shown in its collapsed non-everted state within the holding chamber 18.
- a syringe 30 or other suitable fluid pressure applying device is attached to the pipe 20, as shown in Figure 6.
- the syringe 30 can be operated to apply fluid pressure to the chamber 12.
- the fluid applied may be air or any other fluid (liquid or gas).
- the part 1 of the distal urethra 3 (the 1-2 centimetres furthest from the bladder 5), that is colonised with bacteria, does not contact the catheter 26.
- the lining device 10 can then be removed from the urethra 3, leaving the catheter 26 in position. As shown in Figure 9, the lining device 10 may be removed by pulling it down the catheter 22 to the channel junction 32 of the catheter.
- the catheter 22 is widest at the junction 32, and this causes the liner 12 to split.
- a line of weakness 34 ( Figure 3) may be provided in the liner 12 to facilitate this splitting.
- the lining device (the liner 16 and the chamber 12) may be removed from the patient and discarded.
- the apparatus described in the embodiment may be used in many applications, not just those mentioned in relation to the embodiments.
- the body cavity may be a colon.
- the apparatus of the embodiment may be used in body cavities that are not body cavities of the human or animal body.
- the cavity may be the body cavity of an inanimate object, including an excised or artificial human or animal body part.
- the apparatus described in the embodiment may also be of any length or diameter.
- the chamber 12 and/or liner may have a length sufficient to line the entire urethra 3 (or colon).
