A medical assembly includes a balloon expandable endoprosthesis comprising a plurality of ringed stent elements flexibly connected to each other via at least one flexible connector, the endoprosthesis being deployable from an undeployed state with an undeployed diameter to a deployed state with a deployed diameter. The medical assembly further includes a catheter assembly comprising a balloon, and a cover along the balloon. The endoprosthesis is coaxially located about the balloon and the cover. One or more portions of the balloon and the cover reach an intermediate diameter between the undeployed diameter and the deployed diameter in which the portions of the balloon and the cover are inflated by increasing an inflation pressure within the balloon and approximately maintained at about the intermediate diameter until the inflation pressure increases by at least 1 atmosphere to overcome a yield strength of the cover.

Controlled endoprosthesis balloon expansion

An improved medical device reduces the loss of longitudinal length during expansion of a stent-graft from a compressed state to an expanded state. For example, the stent-graft is placed over a cover that provides resistance to expansion of the balloon during inflation, which reduces longitudinal compressing forces exerted on the stent-graft.

Balloon expandable endoprosthesis

The present disclosure includes an expandable medical device and outer sheath combination. The outer sheath is capable of being split to form multiple sheath sections that may be peeled back to expose a portion or all of the expandable medical device. The medical device, as well as the outer sheath, may include one or more therapeutic agents for delivery to a treatment area within a patient.

Removable covers for drug eluting medical devices

The present disclosure is directed toward a composite balloon comprising a layer of material having a porous microstructure (e.g., ePTFE or expanded polyethylene) and a thermoplastic polymeric layer useful for medical applications. The layers of the composite balloons become adhered through a stretch blow-molding process. Methods of making and using such composite balloons are also described amongst others.
