Publication number: 20230338673Abstract: The application is directed to a mesh nebulizer and related system including a dosing unit for providing a predetermined amount of a therapeutic agent, wherein the therapeutic agent is delivered in a portion container to be opened by pressure. The dosing unit comprises an uptake chamber with a dosing opening for dispensing the therapeutic agent, an opening for inserting a portion container and a locking body for the opening. The locking body is adapted to be moved from an open position in which the locking body releases the opening to a closed position in which the locking body closes the opening. The locking body is further adapted to be moved from the closed position to a drainage position in which the locking body applies pressure to the portion container to open the portion container and release the therapeutic agent.Type: ApplicationFiled: August 20, 2021Publication date: October 26, 2023Applicant: Pulmotree Medical GmbHInventors: Pia GÖRSTNER, Kristian KELLNER, Ulf KRÜGER

Patent number: 9028539Abstract: An inventive flanged graft for end-to-side anastomosis includes a tubular graft member and a flanged section The type and size of the flanged section is determined by various factors such as identity of the receiving artery, position of the arteriotomy on the receiving artery, and luminal diameter of the graft. The graft is preferably anastomosed to the receiving artery using continuous sutures to join the arteriotomy to the peripheral edges flanged section.Type: GrantFiled: September 30, 2005Date of Patent: May 12, 2015Assignee: Bard Peripheral Vascular, Inc.Inventors: Hans Scholz, Ulf Kruger, Utz Settmacher

Publication number: 20120172975Abstract: A medical device which defines a lumen for flowing a bodily fluid from an upstream end of the device to a downstream end thereof is disclosed. The device has a luminal wall (14) that extends between the upstream and downstream ends and defines the lumen within which the fluid flows. The wall exhibits a succession of protuberances spaced from each other along the length of the device. Each protuberance has a flank facing upstream (54) and a flank facing downstream (64), the flank facing upstream extending into the fluid flow so that a radially outermost part of the flow of fluid from the upstream to the downstream end of the device impinges on the upstream flank and is thereby caused to reverse its flow, and flow upstream from the upstream flank to the downstream flank of the next adjacent protuberance upstream, creating micro-vortices between two adjacent protuberances.Type: ApplicationFiled: March 7, 2012Publication date: July 5, 2012Inventors: Hans Scholz, Karen Petzold, Ulf Kruger

Patent number: 6746480Abstract: An inventive flanged graft for end-to-side anastomosis includes a graft with bifurcated flanges. The bifurcated flanges may be symmetrical or asymmetrical relative to one another. The type and size of flange to be used is determined by various factors such as identity of the receiving artery, position of the arteriotomy on the receiving artery, and lumenal diameter of the graft. The graft is preferably anastomosed to the receiving artery using continuous sutures to join the arteriotomy to the peripheral edges of the bifucated flanges. In an alternate embodiment, the inventive bypass graft includes a flared skirt which extends circumferentially about the tubular graft member. The flared skirt has an elliptical shape and is offset from a central longitudinal axis of the graft member.Type: GrantFiled: July 3, 2001Date of Patent: June 8, 2004Assignee: Bard Peripheral Vascular, Inc.Inventors: Hans Scholz, Ulf Kruger, Utz Settmacher
