Abstract: A medical device manufacturing process can include inserting a hollow shaft having a longitudinally-extending slit into the central lumen of a tubular device body, leaving its distal end protruding beyond the device body. The shaft includes an inner layer of a first material and an outer layer of a second material; the second material melts at a lower temperature than the first material. A sensor stack (14), including alternately-disposed spacing elements (14) and sensors (28), is formed around the protruding segment of the shaft. The spacing elements include an inner layer (34a) of a third material and an outer layer (34b) of a fourth material; the third material melts at a lower temperature than the fourth material. The assembly bonded by heating it above the melting temperatures of the second and third materials but below the those of the first and fourth materials.

Abstract: A device includes a bodily implant having a housing defining a cavity. The housing has a top portion. The device includes an electronic control system that is at least partially disposed within the cavity. The device includes a recharge antenna and a communications antenna. The device includes a support member defining a groove. At least a portion of the recharge antenna is disposed within the groove defined by the support member.

Abstract: A device includes a bodily implant having a housing defining a cavity. The housing has a top portion defining a first opening, a second opening, and a third opening. The device includes an electronic control system that is at least partially disposed within the cavity. The device includes a fluid control system having a pump. The fluid control system is at least partially disposed within the cavity. The device includes a recharge antenna having a first portion extending through the first opening of the top portion of the housing and into the cavity defined by the housing. The recharge antenna has a second portion extending through the second opening of the top portion of the housing and into the cavity defined by the housing. The device includes a communications antenna extending through the third opening of the top portion of the housing and into the cavity defined by the housing.

Abstract: A prosthetic heart valve may include a collapsible and expandable stent, a cuff attached to an annulus section of the stent, and a plurality of leaflets attached to at least one of the cuff or the stent within an interior region of the stent. The stent may have a plurality of cells connected to one another in a plurality of annular rows around the stent. The leaflets together may have a coapted position occluding the interior region of the stent and an open position in which the interior region is not occluded. Each leaflet may include a flat mesh of braided wire material having a plurality of pores extending therethrough. The leaflets may be devoid of biological material at a time of implantation.
