The present invention concerns a system for locating an organ wall defect or the origin of an anastomotic / suture line leak during or after surgery, in a positive pressurized body cavity. Said system (1) mainly comprises i) a handheld body or part or housing (2) which is connected to a gas intake or delivery line (3) allowing gas to flow through it from its free tip (3') and is intended to be inserted into the body cavity and being moved around inside it, ii) a measurement unit (4) comprising at least one sensor means (5) able to measure at least one gas property and which preferably also comprises, or is associated or working with, at least some computational means (5') and / or advantageously sensory feedback means (5''), and iii) a back gas line or second gas delivery tube (6) which connects the exit of the measurement unit (4) to the body cavity (BC), the system (1) thus providing a continuous gas flow loop between the body cavity and the measurement unit (4), with said back line allowing advantageously equalization of the gas pressure / flow between the inlet and the outlet of said measurement unit (4).

The invention relates to a medical lock arrangement for providing access to a vessel or hollow organ through the vessel wall or organ wall thereof, comprising a retaining arrangement which can be fixed to the vessel wall or organ wall, and a tube which has a connecting flange on the distal side for detachably fixed and fluid-tight joining to the retaining arrangement. The invention is characterised in that the tube has a tube wall through which at least one access channel projects laterally with respect to the longitudinal extent of the tube, through which access channel at least one inflatable body can be introduced into the tube and can be filled with and emptied of a medium, or an inflatable body arranged in the tube wall can be filled with and emptied of a medium, and in that the inflatable body is designed in such a way that, in the filled state, the inflatable body rests against the entire circumference of an inner tube wall which can be allocated to the tube, and can seal the tube fluid-tightly in the longitudinal extent of the tube.

A medical instrument for creating an opening in a vessel or organ wall is described, comprising a penetration body attached distally to a shaft arrangement having a longitudinal shaft axis, which has a first body section and a second body section adjoining the first body section proximally, the latter at least partially delimiting a cavity radially to the longitudinal shaft axis and having a cutting blade radially enclosing the cavity proximally. The invention is characterized in that the penetrating body comprises at least one first and one second penetrating body segment, each having a first and a second body section. The first body section of the first penetrating body segment terminates distally with a point, while the second section at least partially delimits a first cavity and has a cutting blade radially enclosing the first cavity. The first body section of the second penetrating body segment tapers distally in cross-section and has a recess distally facing the first penetrating body segment, into which the second body section of the first penetrating body segment can be partially inserted. Furthermore, the second body section partially delimits a second cavity and has a cutting blade radially enclosing the second cavity.

A medical sluice arrangement is described for creating access to a vessel or hollow organ through its vessel or organ wall, comprising a holding arrangement that can be fixed to the vessel or organ wall and a tube that has a connecting flange distally for detachably tight and fluid-tight attachment to the holding arrangement. The invention is characterized in that the tube has a tube wall through which at least one access channel projects laterally to the longitudinal extent of the tube, through which at least one inflatable body can be inserted into the tube and filled and emptied with a medium, or an inflatable body arranged in the tube wall can be filled and emptied with a medium, and that the inflatable body is designed such that, in the filled state, the inflatable body fully conforms to an inner tube wall associated with the tube and is able to seal the tube fluid-tight along its longitudinal extent.

A tubular nonwoven structure as an active agent carrier (“sleeve”) for the atraumatic treatment of hollow organs, in particular applicable via a balloon catheter, as well as a method for the production thereof, wherein the sleeve is folded about a longitudinal sleeve axis in an initial state and is unfoldable in a final state for attachment to an inner wall of a hollow organ, the tubular sleeve is formed of first biodegradable polymer nanofibers and the folding of the sleeve is directed as pleating about a longitudinal sleeve axis, a medicinal active agent is incorporated into the first polymer nanofibers and / or is arranged in interspaces between the polymer nanofibers, and the first polymer fibers are formed such that the polymer fibers degrade over a period of 2 weeks to 3 months so that the active agent can be delivered to a hollow organ wall in this period of time.

This invention discloses a surgical marking device for use in surgical procedures, comprising: a surgical marking device body, wherein the surgical marking device body has a punching position marking hole for marking punching positions and a suture marking groove located outside the punching position marking hole for marking suture positions. This invention marks the locations where punching is required on the walls of tissues and organs by using the punching position marking hole and the suture marking groove on the surgical marking device body, thus meeting the needs of accurately determining punching locations on the walls of tissues and organs while simultaneously removing surrounding foreign objects.

A surgical instrument for treating tubular organs includes a shaft assembly, a stapling assembly, a trocar, and one or more light sources. The stapling assembly is disposed at the distal end of the shaft assembly and includes a circumferential wall having a distal edge that defines a staple line. The trocar is operably movable relative to the stapling assembly along its axis between an extended position and a retracted position. One or more light sources are for emitting light that can penetrate the wall of the tubular organ. In this way, by detecting the light that has penetrated the wall of the tubular organ, the user of the surgical instrument can locate the trocar, the distal edge of the stapling assembly, or both within the tubular organ.

The invention relates to a medical instrument for producing an opening in a vessel or organ wall, having a penetrating body that is attached on the distal side to a shaft assembly having a shaft longitudinal axis and that has a first body section and a second body section adjoining the first body section on the proximal side, wherein the second body section delimits a cavity radially to the shaft longitudinal axis at least in some regions and has a cutting blade radially surrounding the cavity on the proximal side. The invention is characterised in that the penetrating body is composed of at least a first and a second penetrating body segment, which have a first and a second body section. The first body section of the first penetrating body segment ends at the distal end with a tip, and the second body section delimits a first cavity at least in some regions and has a cutting blade which radially surrounds the first cavity. The first body section of the second penetrating body segment tapers in the distal direction in the cross-section and has a recess facing the first penetrating body segment on the distal side, into which recess the second body section of the first penetrating body segment can be partially inserted. Furthermore, the second body section delimits a second cavity in some regions and has a cutting blade that radially surrounds the second cavity.
