Patent number: 11839380Abstract: Detachment of a medical device from a delivery assembly can utilize features of electrolytic detachment and features of mechanical detachment. Detachment zones can facilitate mechanical retention of the medical device as well as electrolytic corrosion of portions of the delivery assembly to allow mechanical release of the medical device. Such a delivery system, can include an implant comprising a hub, the hub defining an aperture having an aperture cross-sectional dimension; and a delivery wire comprising (i) a core member extending through the aperture and (ii) a stopper positioned distal to the aperture, the stopper having a first cross-sectional dimension larger than the aperture cross-sectional dimension, and the stopper being electrolytically corrodible to reduce the first cross-sectional dimension to a second cross-sectional dimension smaller than the aperture cross-sectional dimension.Type: GrantFiled: September 23, 2020Date of Patent: December 12, 2023Assignee: COVIDIEN LPInventor: Madhur Kadam

Patent number: 11596414Abstract: An occlusive device for occluding a target area can include an elongate member having opposing first and second side edges extending longitudinally along the member and a member width. The member can have a collapsed configuration in which the first and second side edges are curled toward each other about a longitudinal axis of the member. Further the member can have an expanded configuration in which the member form a series of loops and the first and second side edges uncurl to be spaced apart from each other.Type: GrantFiled: August 28, 2019Date of Patent: March 7, 2023Assignee: COVIDIEN LPInventors: Vincent Divino, Richard Rhee, Earl Bardsley, Julie Kulak, Madhur Kadam, Ramon Carrillo, Kokou A.

Publication number: 20210000477Abstract: Delivery and detachment of an implant can be enhanced by a retraction mechanism to secure portions of a delivery wire within an interior space of the implant. A delivery system can include an implant having a proximal end portion. A delivery wire can include (i) a detachment zone proximal to the proximal end portion and (ii) a distal region distal to the proximal end portion. An expansion member can be located between the proximal end portion and the distal region of the delivery wire. The expansion member can be biased to move the distal region of the delivery wire distally away from the proximal end portion when severed at the detachment zone.Type: ApplicationFiled: September 24, 2020Publication date: January 7, 2021Inventors: Richard Rhee, Madhur Kadam, Vincent Divino

Publication number: 20160331377Abstract: Detachment of a medical device from a delivery assembly can be electrolytic and provide flushing with an infusion of fluid to enhance detachment procedures. A device providing such capabilities can include a catheter having a lumen; a core member extending through the lumen; an implant attached to the core member by an electrolytic detachment junction, the detachment junction being radially adjacent to an electrode within the lumen; and a pump in fluid communication with a distal end region of the catheter through the lumen, the pump being configured to provide a flow of a fluid between the return electrode and the detachment junction. The implant can be positioned at a target location. The electrode can be positioned radially adjacent to the detachment junction. A voltage potential is applied while a fluid is flushed between the detachment junction and the electrode through the lumen of the catheter.Type: ApplicationFiled: May 11, 2015Publication date: November 17, 2016Inventors: Vincent Divino, Madhur Kadam
