摘要： A steerable delivery catheter includes an outer sheath with a housing disposed at a distal end thereof to define a chamber for a medical device, the chamber having an open distal end and a proximal inner shelf. An inner shaft is slidably disposed within the sheath and has an abutment attached to the distal end of the shaft, the abutment being slidably contained within the chamber. During navigation of the catheter, when the inner shaft is tensioned the abutment engages the shelf to apply a compressive force to the sheath to selectively deflect a distal region of the catheter. When the catheter has been navigated to the deployment site the sheath is withdrawn while the abutment maintains the medical device in place as it is deployed. A delivery method also is disclosed.

摘要： A delivery catheter and method for delivering and deploying an implantable medical device include a mechanical latch by which the device can remain firmly attached at a single point of connection to the delivery catheter during deployment of the device. The delivery catheter provides simple yet firm control of the release mechanism to enable the clinician to confirm the accuracy of the deployment before releasing the tether or, if the placement of the device should be corrected, the tether can be maintained while the device is recaptured and repositioned or removed from the patient.

摘要： A delivery device for implanting a medical device that includes an expandable fixation member adapted to fix the position of the medical device within a lumen of a human body. The delivery device has an inner shaft rotatably disposed in a tubular outer shaft. A retention member is secured to and rotatable with the inner shaft and has a free end and a retainer portion adapted to protrude outwardly through an exit aperture in the outer shaft to extend circumferentially about the exterior of the outer shaft. The fixation member of the medical device may be retained on the tubular shaft in a low profile configuration by the outwardly protruding retainer portion and may be released to expand upon retraction of the retainer portion in response to rotation of the inner shaft.

摘要： A mandrel includes a mandrel body with a proximal major diameter barrel section, a diameter reducing/tapered portion and a distal minor diameter barrel section. The tapered portion connects the proximal major diameter barrel section and distal minor diameter barrel section. The proximal major diameter barrel section has a major diameter, the distal minor diameter barrel section has a minor diameter, the minor diameter less than the major diameter. The minor diameter is less than a diameter of an inner lumen of a coaxial catheter, and the major diameter exceeds the inner diameter of the outer lumen guidewire exit port of the coaxial catheter, and the tapered portion is sized to form a fluid seal the inner diameter of the outer lumen guidewire exit port. The distal minor diameter barrel section of the mandrel occupies and substantially seals and prevent flow through it to the catheter distal end guidewire entry port.

摘要： The present invention is a device for delivering a self-expanding stent. The device has an inner and an outer shaft moveable with respect to the inner shaft. The self expanding stent is received on the inner shaft adjacent its distal end. A tapered tip is located on the inner shaft distal end and it forms a smooth transition from the deliver y device to the guide wire extending therethrough. A handle allows the practitioner to deploy the stent single handedly. The stent may have its segments in a first radial configuration for deliver of the stent or the stent may have a plurality of segments in a first radial configuration and a plurality of second segments in a second radial position.
