Abstract
A body of a device for positioning a coronary stent or a coronary balloon within coronary arteries is described. The body is formed of a front part and a rear part. The front body part represents, on the one side, a truncated part having a tubular extension with a cutout for connection to a Y-connector and, on the other side, successively passes into a cylindrical part, a cylindrical smooth part of a smaller diameter and a runner guide. The smooth surface of the rear body part is housed over the cylindrical smooth front body part, and the inside surface provided with the circumferential double-thread for engaging with the runner protrusions is housed over the runner. Through-holes for introducing the coronary stent or coronary balloon delivery system inside the device housed in the body are formed in the tubular extension of the front body part.

[0210] A chamfer 16 (FIG. 2, FIG. 3, FIG. 6) enabling a smooth and convenient contact of the body end part with the surgeon's palm is formed in the end surface 38 (FIG. 4, FIG. 10) of the rear body part.
[0211] Through-holes 21 (FIG. 4, FIG. 5, FIG. 6) for introducing the coronary stent or coronary balloon delivery system inside the device housed inside the body are provided in the tubular extension 33 (FIG. 5, FIG. 7, FIG. 9) of the front body part provided with the cutout 34 (FIG. 5, FIG. 7, FIG. 9) for the coronary guide 31 (FIG. 7) and in the end surface 38 (FIG. 4, FIG. 5) of the rear body part 14 (FIG. 1, FIG. 2, FIG. 3, FIG. 4, FIG. 5, FIG. 6, FIG. 7).
[0212] The body is made of plastic by injection molding and is formed of a front part 1 and a rear part 14 (FIG. 1, FIG. 2, FIG. 3, FIG. 5, FIG. 7) each representing two identical halves.
[0213] As an embodiment, the halves may be provided with an offset single-thread 41 (FIG. 8) to form a common threaded surface when assembling the device.
[0214] The halves are made separately and connected to each other, once the mechanism is assembled, using tapered protrusions 2, 22 (FIG. 4, FIG. 5) and matching tapered holes 3, 23 (FIG. 4, FIG. 5) formed along the edges of the inner body part.
[0215] When assembling the device, the rubber bush 39 (FIG. 5) with the hole for receiving the delivery system and the cap 40 (FIG. 5) with the hole for receiving the delivery system are first successively housed in the retainer 28 (FIG. 4, FIG. 5) on the thickened side and the runner 24 (FIG. 4, FIG. 5) with the hole for receiving the delivery system is housed on the opposite side of the retainer 28 (FIG. 4, FIG. 5) and the cap 40 (FIG. 5) with the rubber bush 39 (FIG. 5) inside is threaded into said hole. Then, the tube 32 (FIG. 1, FIG. 4) is introduced into the through-hole formed in the bush 39, cap 40 and runner 24 for arranging therein the coronary stent or coronary balloon delivery system.
[0216] The retainer 28 (FIG. 4, FIG. 5) with the rubber bush 39 (FIG. 5), cap 40 (FIG. 5) and runner (FIG. 4, FIG. 5) is housed inside the front body part 1 (FIG. 4) with the thickened part of the retainer 29 (FIG. 4, FIG. 5) accommodated in the cylindrical body part 7 (FIG. 4) with the side holes 8 (FIG. 1, FIG. 4) for the lugs 30 (FIG. 1, FIG. 4) of the retainer 28 (FIG. 1, FIG. 4) and the rest of the retainer is accommodated in the cylindrical smooth part of the front body part 9 (FIG. 4).
[0217] The halves of the front body part are connected using tapered protrusions 2 (FIG. 4, FIG. 5) and matching tapered holes 3 (FIG. 4, FIG. 5) formed in the front body part 1 (FIG. 4) whereafter the cylindrical smooth part of the front body part 9 (FIG. 4) is housed in the halves of the rear body part 14 (FIG. 4) and the cylindrical protrusion 18 (FIG. 5, FIG. 6) with point elements 19 (FIG. 5, FIG. 6) is housed in the cylindrical slot 11 (FIG. 5) with point elements 12 (FIG. 5) formed in the cylindrical smooth part 9 of the front body part (FIG. 5), wherein the halves of the rear body part are connected similarly to those of the front body part using tapered protrusions 22 (FIG. 5, FIG. 6) and matching tapered holes 23 (FIG. 5, FIG. 6) in the rear body part 14 (FIG. 4) to form thereby an overlapping connection between the front body part 1 (FIG. 4) and the rear part 14 (FIG. 4) of the body.
