US Patent:

20210085328, Mar 25, 2021

Filed:

Sep 30, 2020

Appl. No.:

17/039569

Inventors:

- Newark DE, US
Daniel H. Todd - North East MD, US

International Classification:

A61B 17/11
A61B 17/00
A61F 2/06
A61F 2/90

Abstract:

Implantable medical devices for connecting tissue layers or occluding body conduits and tissue structures include apposition portions, a central region, and a covering material. The methods of using the devices include endoscopic deployment, and the devices may include self-expanding frameworks that facilitate a secure connection between the tissue structures. In some embodiments, one or more tethers are used to longitudinally contract the device in situ.

International Classification:

A61M 5/31
A61L 31/04
A61L 31/14
A61M 5/315

Abstract:

The present disclosure relates to medical delivery devices that include a barrel having an inner surface, and in at least one embodiment, the inner surface is hydrophilic. The medical delivery device may further include a stopper may having an elastomeric body, one or more fluoropolymer layers, and two or more ribs laminated to the one or more fluoropolymer layers. In some embodiments, the contact angle of the inner surface of the barrel is less than about 58. Additionally, the stopper includes a sliding surface that is less than about 2.0 mm. The barrel provides inner surface that in combination with the fluoropolymer laminate or fluoropolymer film achieve high levels of air and liquid impermeability while also maintaining an acceptably low break loose force, low average glide force, and low glide force variation. In some embodiments, the compressibility stopper against the barrel is greater than about 7.9%.
