摘要:
A tissue cutting device is disclosed, comprising a tubular part, that is structured and arranged to be inserted in a temporary delivery shape through a vascular system into a body vessel, and to be subsequently subjected to a change of shape, from said temporary delivery shape via an expanded delivered shape to a further expanded shape, extending at least beyond an outer surface of said body vessel in order to create a cutting action configured for cutting said body vessel, wherein said tissue cutting device is structured and arranged to penetrate a wall of said body vessel by said cutting action, in such a manner that a cut of said tissue created by said cutting action is continuously replaced by scar tissue, wherein the tubular part of said device comprises a plurality of segments connected to each other in longitudinal direction of said tubular part of said device, wherein a first segment of said plurality of segments has a dimension in a direction perpendicular to said longitudinal direction of said tubular part of said device that is larger than that dimension of a second segment thereof, at least in said expanded delivered shape.
摘要:
A tissue cutting device is disclosed, which is structured and arranged to be inserted through the vascular system into a body vessel adjacent to the heart and/or into the heart, and to be subsequently subjected to a change of shape in order to penetrate into the heart tissue. The tissue cutting device may thus be used for treating disorders to the heart rhythm regulation system. A kit of tissue cutting devices provides a plurality of devices for creating a lesion pattern for treating such disorders. The tissue cutting device is of a biodegradable material, such as hydrolytically degradable material or an enzymatically degradable material.

A tissue lesion creating device (30) is structured and arranged to be inserted through the vascular system into a body vessel adjacent the heart and to be subsequently subjected to a change of shape in order to penetrate into the heart tissue. The tissue lesion creating device may thus be used for treating disorders to the heart rhythm regulation system. A kit of devices (30, 38, 54, 68, 82, 100) provides a plurality of devices for creating a lesion pattern for treating such disorders.
摘要:
A hemostatic valve unit having a splittable housing. The hemostatic valve comprising housing parts radially movable when said housing is split. Said hemostatic valve comprising a through port with proximal and distal openings configured to provide a communication channel for delivery of a medical device to and/or from the interior of a heart.
