A continuous punching method comprises: providing a sheet material, applying a first punching process of a first punch station to the sheet material, and applying a second punching process of a second punch station to the sheet material. The first punching process includes: adjusting a punching depth of a punch blade of the first punch station to determine a lateral length to be punched out by the punch blade, and forming two longitudinally spaced apart first punched slits on the sheet material through the punch blade. The second punching process includes: adjusting lateral positions of two punch blocks of the second punch station, and forming two laterally spaced apart second punched areas on the sheet material through the punch blocks. The two first punched slits and the two second punched areas communicate with each other to form a contour of a combined cut-out.

A device for joining individual leaflets for repairing a cardiac valve of a patient has a base and projection fingers rising from the base to support adjacent leaflets for tacking together by sewing overlapping edges of adjacent leaflets prior to emplacement into the patient. The invention provides a cutting tool for excising leaflets from a pericardial tissue sheet according to predetermined sizes and shapes. A leaflet having a desired contour and size is obtained by pressing the tool formed as a cutter block against the tissue sheet. A set of blocks can be provided wherein each cutter block has an outer edge following a respective contour and size for a leaflet, and wherein the outer edge includes a raised cutting edge for pressing through the pericardial tissue sheet. The blocks can be held in a press for assisting in pushing the cutting edge through the tissue.

A tool unit (II) includes an ability to change the width (B) of a punching gap between a first tool (12) and a second tool (13). A plurality of second tools (13) jointly form a die tool with a circumferential die cutting edge in which the first tool (12) can engage with a cutting edge (22). Between the cutting edge (22) of the first tool and the respective cutting edge (21) of a second tool (12) a punching gap (23) is formed with a width (B) measured between the cutting edges (21, 22) across the working direction (A). Via lamping means (33), the deformation force acting on a second tool (13) can act transversely to the working direction (A), whereby the position of the affected cutting edge (21) and, with it, the width (B) of the punching gap (23), can be changed and set.

A draw stud connector, for use on a punch driver, includes a draw stud having a first end. The draw stud connector also includes a body defining an axis therethrough, the body forming a cavity having an open end, and a wedge at least partially positioned within the cavity and moveable with respect to the body both axially and radially. The wedge allows the first end of the draw stud to move axially into the cavity but does not permit axial removal of the first end of the draw stud from the cavity.
