  • Patent number: 10478591
    Abstract: A stent graft delivery device that is pre-loaded with a single guide wire for both tracking the device within a main vessel as well as for cannulating one or more branch vessels is described. The delivery device comprises a delivery catheter having a prosthesis releasably secured thereto and a nose cone extending from the proximal end of the catheter. In a delivery configuration, a secondary catheter is coaxial with the guide wire and extends through at least a portion of the prosthesis lumen and is held within a channel formed in the nose cone. In a released configuration, secondary catheter and guide wire are retracted distally out of the channel formed in the sidewall of the nose cone dilator and can be manipulated for cannulating a branch vessel.

  • Publication number: 20180200089
    Abstract: The present embodiments describe an endograft having at least one fenestration, at least one cuff support structure, and at least one branch stent, and methods for deploying the same. In one example, the system comprises a branch stent within the cuff support structure, where upon expansion of the branch stent, the cuff support structure expands from a first state to a second state and has a radially inward bias towards the smaller first state. In another example, the system comprises a cuff support structure having at least one barb, where the barb is flush with the cuff support structure in a first state, and where upon expansion of the cuff support structure to a second state, the barb deflects radially inward. Both the radially inward bias of the cuff and radially inward deflection of the barb may facilitate an interference fit between the cuff and the branch stent.

  • Patent number: 10016293
    Abstract: The present embodiments provide delivery systems. In one embodiment, the delivery system includes a cannula having proximal and distal regions and a lumen extending therebetween. An atraumatic tip is coupled to the proximal region of the cannula. A proximal region of a housing component is disposed at least partially within a cavity of the atraumatic tip and secured to the atraumatic tip, and a distal region of the housing component extends at least partially distally beyond the atraumatic tip. A proximal region of a trigger wire is housed within the distal region of the housing component in a delivery state.

  • Patent number: 9347533
    Abstract: A drive system is provided for rotating a biopsy member. The drive system includes a pinion connected to the biopsy member and a rack that drives the pinion during a drive stroke. During the return stroke, the rack rotates away from the pinion so that the rack is not engaged with the pinion during the return stroke. Thus, the pinion is only driven during the drive stroke but not during the return stroke. As a result, the biopsy member rotates in a single direction as a trigger is repeatedly pressed and released.

  • Patent number: 9346181
    Abstract: A cutting tool is provided for cutting the end of a catheter to provide custom length catheters. The cutting tool has a cutting member that moves within the cutting passageway in the housing. The catheter is positioned within a catheter passageway in the housing. The cutting passageway transacts the catheter passageway so that a blade on the cutting member crosses the catheter passageway and cuts through the width of the catheter to form a cut end on the catheter.
