Abstract: A prosthetic heart valve leaflet includes a plurality of electrospun fibers at least partially embedded in a polymer matrix. The plurality of fibers includes a first polyisobutylene urethane copolymer having a first predetermined weight average percentage of hard segment portions and the polymer matrix includes a second polyisobutylene urethane copolymer having a second predetermined weight average percentage of the hard segment portions, wherein the first predetermined weight average percentage of the hard segment portions is greater than the second predetermined weight average percentage of the hard segment portions.

Abstract: A medical device may include a stimulation member configured to apply a stimulus to a nerve that is configured to control a contraction of an airway distal to the nerve, and a measurement member configured to measure an effect of the stimulus on the airway. The medical device also may include an energy delivery element configured to deliver energy to tissue defining the airway to reduce an effect of the stimulus on the airway. The energy delivery element may be disposed at or distally of the stimulation member.

Abstract: A heart valve anchor has a body that includes a distal portion, a distal end, a proximal portion, and a proximal end. The distal end and the proximal end define a longitudinal axis. The body has an expandable portion that includes a first radially expandable portion at the distal portion of the body, a second radially expandable portion at the proximal portion of the body, and a root portion disposed between the first and second radially expandable portions. The body has a first configuration adapted to be housed at least partially within a tissue penetrating device, and a second configuration in which the first and second radially expandable portions are partially or fully expanded such that the anchor engages tissue in a region between the first and second radially expandable portions.

Abstract: A prosthetic heart valve provided herein can include a cultured cell tissue leaflet. In some cases, a prosthetic heart valve can include a plurality of leaflets secured together and retained within the expandable tubular member. The cultured cell tissue can be obtained by culturing fibroblast cells, smooth muscle cells, or a combination thereof to form a sheet of cultured cells and chemically cross-linking the fibroblast cells while under tension. In some cases, the cultured cell tissue can be radially tensioned. In some cases, the cultured cell tissue can be bi-axially tensioned.
