Publication number: 20230320734Abstract: A device for occlusion of a body lumen comprises an implantable occlusion apparatus (3) operably attached to an elongated catheter member (4) configured for transluminal delivery and deployment of the occlusion apparatus in the body lumen. The occlusion apparatus comprises a radially expansible element (5) detachably attached to the elongated catheter member, and adjustable between a contracted orientation suitable for 10 transluminal delivery and a deployed orientation configured to occlude the body lumen, an energy delivery element (6, 14, 21) configured to deliver energy to surrounding tissue to heat the tissue, and a sensor (7) configured to detect a parameter of the wall of the body lumen. The energy delivery element (6, 14, 21) and sensor (7) are axially movable independently of the radially expansible element whereby, in use, the energy delivery 15 element and sensor can be transluminally retracted leaving the radially expansible element in-situ occluding the body lumen.Type: ApplicationFiled: June 13, 2023Publication date: October 12, 2023Applicant: NATIONAL UNIVERSITY OF IRELAND, GALWAYInventors: Tony O'HALLORAN, John THOMPSON, Martin O'HALLORAN, Faisal SHARIF

Publication number: 20070235899Abstract: A method for constructing stent retention features on a pre-formed stent deployment balloon includes folding the pre-formed balloon into a folded configuration for subsequently retaining an undeployed stent. The balloon is then inserted in the folded configuration into at least one sheath defining a pattern of openings.
