  • Patent number: 11013627
    Abstract: Stent delivery systems as well as methods for making and using stent delivery systems are disclosed. An example stent delivery system may include an elongate shaft including an inner member having a stent receiving region and a deployment sheath slidably disposed along the inner member. A handle may be coupled to the elongate shaft. A rack member may be coupled to the deployment sheath. At least a portion of the rack member may be designed to extend within the handle. The rack member may include a base portion and a displaceable portion that is displaceable relative to the base portion.

  • Publication number: 20210100672
    Abstract: Stent delivery systems and methods for making and using stent delivery systems are disclosed. An example stent delivery system may include an inner member having a stent receiving region, a stent disposed along the stent receiving region, a deployment sheath axially slidable relative to the inner member, the deployment sheath having a proximal end region, a handle coupled to the deployment sheath, a rod coupled to the handle, the rod having a distal end region, a proximal end region and a first threaded portion extending from the distal end region to the proximal end region and a coupling member configured to couple the rod to the deployment sheath, the coupling member having an engagement portion. Additionally, the first threaded portion of the rod is designed to engage the engagement portion of coupling member and rotation of the rod is designed to translate the coupling member along the rod.

  • Publication number: 20190247614
    Abstract: An example introducer and method of use is disclosed. The example introducer sheath includes a shaft including a tubular portion, an expandable portion coupled to the tubular portion and a longitudinal axis. Additionally, the expandable portion includes a first pair of leaflets and a second pair of leaflets and both the first pair of leaflets and the second pair of leaflets extend along the longitudinal axis. Additionally, the second pair of leaflets are spaced radially inward of an inner surface of the first pair of leaflets and the expandable portion is designed to shift between a first configuration and a second expanded configuration.

  • Publication number: 20170246017
    Abstract: Medical devices, medical device systems, and methods for making and using the same are disclosed. An example medical device may include an inner shaft having a stent receiving region. A bumper shaft may be disposed about the inner shaft. A deployment sheath may be slidably disposed about the inner shaft. The deployment sheath may have a body region and a distal stent covering region. The distal stent covering region may have an outer diameter that is smaller than an outer diameter of the body region.

  • Publication number: 20150306360
    Abstract: A drug delivery device that uses centrifugal force to deliver a drug to a body lumen wall. The drug delivery device comprises an impeller that includes an impeller shaft; an impeller head at the distal end of the impeller shaft; a drug lumen; an impeller housing; and a housing shaft attached to the impeller housing. In use, the drug is advanced along the drug lumen to the impeller head; at least the impeller head is rotated so that when drug exits the drug lumen, the centrifugal force of the rotating impeller causes the drug to move radially outward from the drug delivery device, towards and into the body lumen wall.
