Patent number: 12121444Abstract: Implantable drug-eluting device comprising a microporous structure having regularly arranged pores in at least two different uniform sizes, and manufacturing method. The pores are configured for receiving a drug and are being connected by interconnections. Interconnections originating from pores of a first size have a first elution area and interconnections originating from pores of a second size have a second elution area. The interconnections convey the drug to a surface of the device for elution to surrounding tissue. The ratio between the first and the second elution areas is predefined and selectable. The differently sized elution areas provide for different outflow rates. This allows for simple but reliable dispensing of drugs at positively controlled and well determined rates. Particularly, this enables a single implantable device to dispense drugs over preselectable durations of time, like short-term or long-term.Type: GrantFiled: May 23, 2023Date of Patent: October 22, 2024Assignee: WALDEMAR LINK GMBH & CO.

Publication number: 20240341965Abstract: Disk-shaped augmentation for filling bone defects, in particular at the end of long bones, such as the tibia, including a first side, a second side, an outer sheath on lateral sides and an inner wall for a through-opening, running from the first to the second side, for a anchoring keel of an endoprosthesis arranged on the second side. The augment is generally C-shaped with two legs flanking the through-opening. According to the invention, a connecting piece between the legs is designed in an articulated manner and cooperates resiliently with the legs such that a frame is formed, and an outwardly directed restoring force is generated when the legs are compressed.Type: ApplicationFiled: August 16, 2022Publication date: October 17, 2024Applicant: Waldemar Link GmbH & Co.

Publication number: 20240156603Abstract: An augment device includes a hollow sleeve surrounding a channel extending through the hollow sleeve from a top to a bottom of the hollow sleeve, the hollow sleeve comprising a wall having an inner face and an outer face. The hollow sleeve includes at least one bending joint, the bending joint being configured for compressing the channel. Thereby the hollow sleeve may be compressed under an external force, leading to a decreased circumference and width of the hollow sleeve. This leads to a gap between the perimeter of the augment device and surrounding bone material, breaking any connections. By virtue of this, a much facilitated removal of the augment device can be achieved. Further, an extraction tool includes grippers for engaging and compressing the augment device, and further instruments, particularly a jig, for achieving an effective removal.Type: ApplicationFiled: January 25, 2024Publication date: May 16, 2024Applicant: Waldemar Link GmbH & Co.
