Abstract
A release device for releasing a medical implant from an insertion device, in which the implant can be released by a relative movement between a first and a second insertion element, wherein the insertion device has a proximal end, which faces the user during use, and a distal end, which is distanced from the user during use. Between the proximal and the distal end, a shortening region is provided, in which, when generating a targeted relative movement between the first and the second insertion element of the insertion device, a length of at least one of the insertion elements between the proximal end and the distal end can be shortened.
Claims13
A release device for releasing a medical implant from an insertion device, in which the implant can be released by a relative sliding movement between inner and outer shafts, wherein the outer shaft has a proximal end, wherein the proximal end faces the user during use, and a distal end, which is distanced from the user during use, and wherein between the proximal and the distal end, a shortening region is provided separated from the proximal end and the distal end, in which, when generating a targeted relative movement between the inner and outer shafts of the insertion device, a length of the outer shaft between the proximal end and the distal end can be shortened through the shortening region by outwardly bulging the shortening region and folding upon further shortening the shortening region, wherein the shortening region comprises a pre-slitted region with at least one slitted segment along the axial extent thereof, and further comprising a winder that winds a thread that is fastened to the distal end of the pre-slitted region.
An insertion device for inserting a medical implant, which can be released by a relative sliding movement between inner and outer shafts, the outer shaft being pre-configured to shorten in a shortening region between a proximal end and a distal end of the outer shaft, wherein the shortening region is separated from the proximal and distal ends, wherein the shortening region is configured so that a length of the cuter shaft can be shortened through the shortening region by outwardly bulging the shortening region and folding upon further shortening the shortening region, and wherein the shortening region comprises a pre-slitted region with at least one slitted segment along the axial extent thereof, and further comprising a winder that winds a thread that is fastened to the distal end of the pre-slitted region.
A release device for releasing a medical implant from an insertion device, in which the implant can be released by a relative movement between inner and outer shafts, the outer shaft being pre-configured to fold in a shortening region thereof, wherein the insertion device has a proximal end contained within a handle, wherein the proximal end faces the user during use, and a distal end, which is distanced from the user during use, and wherein between the proximal and the distal end, the shortening region is provided, in which, when generating a targeted relative movement between the inner and outer shafts of the insertion device, a length of the outer shaft between the proximal end and the distal end can be shortened by folding the shortening region, wherein the shortening region is a region of the outer shaft that is separated from a proximal end of the outer shaft, and wherein the proximal end of the outer shaft abuts an interior portion of the handle, and wherein the shortening region is configured to outwardly bulge and fold upon further shortening during the relative movement between the inner and outer shafts.
