Operation element, operation set and method for use thereof
First Claim
1. An operation element for use in surgery, comprising a first part for positioning on the outside of a wall of a bodily part containing bodily fluid and at least a second part for positioning in or on the inside of said wall, said second part being connected to said first part and having a free end, for extending into and/or through said wall, wherein the first and second part have surfaces facing each other, such that during use a wall part of said wall is enclosed between said facing surfaces of said first and second part.

- 1. An operation element for use in surgery, comprising a first part for positioning on the outside of a wall of a bodily part containing bodily fluid and at least a second part for positioning in or on the inside of said wall, said second part being connected to said first part and having a free end, for extending into and/or through said wall, wherein the first and second part have surfaces facing each other, such that during use a wall part of said wall is enclosed between said facing surfaces of said first and second part.

30. A method for connecting a shunt to a bodily part such as a blood vessel, for example an artery or vein, comprising the steps of:
-
inserting at least one supporting second part of an operation element into and/or through the wall of a bodily part;
positioning said second part within said bodily part against or in said wall and positioning a first part of said operation element, which is connected to said second part, against the outside of said wall, thereby forcing a part of said wall enclosed between said first part and said second part in a substantially planar form; and
connecting a shunt to said operation element. - View Dependent Claims (34, 35, 36, 37, 38)

31. A method according to claim 31, using a substantially ring shaped element, comprising the steps of:
-
sticking a front end of said ring shaped element through said wall, said ring shaped element having more than one winding;
moving said ring shaped element such that at least a second part of at least one winding is brought in or under said wall, whereas a first part of the ring shaped element is kept on the opposite outer side of said wall;
whereby said part of said wall is clamped between said part of said winding under said wall and said part of said ring shaped element on the outer side of said wall. - View Dependent Claims (32, 33)

- 41. A bodily part, provided with an operation element having a first and at least one second part, connected to said first part by an intermediate part, said first part extending outside said bodily part and said at least one second part extending inside said bodily part, said intermediate part extending into or through the wall of said bodily part, said first and second part enclosing and clamping a wall part of said bodily part, said wall part being substantially flattened by said first and said at least one second part.
- 46. An operation element for use in surgery, comprising a first part for positioning outside on the outer wall of a bodily part containing a bodily fluid, at least a second part for positioning inside said vessel, in or in contact with said wall, said second part being connected to said first part by an intermediate part, said first and second parts have surfaces facing each other wherein, during use said surfaces enclose said wall from opposite sides, directly or by means of pressure on other parts and, the surfaces directly in contact with the wall exerting pressure on the wall from opposite sides are arranged to define essentially parallel planes and all parts arranged not to obstruct a central, essentially cylindrical lumen of a shunt to be connected to said first part, the axis of which at said first part encloses an angle of less than 60 degrees with the normal axis of both of the planes created by said facing surfaces of said first and second parts enclosing said vessel wall.
