Abstract: An occlusive medical device system may include an elongate shaft having a lumen extending longitudinally through a tubular body portion and a plurality of retaining arms extending distally from the tubular body portion. An occlusive medical device may include a proximal tubular mounting portion fixed to an expandable occlusive element. A release wire may be axially translatable between a distal engagement position and a proximal released position, the release wire having a distal engagement portion and a distal retention portion distal of the distal engagement portion. The distal engagement portion may be configured to engage the plurality of retaining arms in the distal engagement position, thereby urging the plurality of retaining arms into releasable engagement with the proximal tubular mounting portion, wherein when the release wire is in the proximal released position, the plurality of retaining arms is deflectable radially inward to disengage from the proximal tubular mounting portion.

Abstract: A system for use in a transseptal crossing procedure includes an outer cannula having a proximal end, a tapered distal end, a preset curve, and a proximal portion extending between the proximal end and the preset curve. An inner member is configured to slide within the outer cannula between a first position and a second position, the inner member has a stiffness greater than a stiffness of the outer cannula. In the first position the tapered distal end is positioned approximately 90 degrees relative to the proximal portion and in the second position the tapered distal end is positioned greater than 90 degrees relative to the proximal portion. A control mechanism includes a first portion connected to the outer cannula and a second portion connected to the inner member, and is configured to move the inner member between the first position and the second position.

Abstract: An occlusive implant system may include an access device including a handle and an access sheath extending distally therefrom. The access device includes a working lumen extending longitudinally therethrough. A proximal portion of the working lumen defines a garage section and a distal portion of the working lumen extends distally of the garage section. The occlusive implant system may include an occlusive implant device including a delivery sheath configured to be received within the garage section, the delivery sheath having a delivery lumen, a core wire disposed therein, and an occlusive implant releasably attached to the core wire. The garage section has a first inner diameter and the distal portion of the working lumen has a second inner diameter less than the first inner diameter. The delivery sheath has an outer diameter less than the first inner diameter and greater than the second inner diameter.

Abstract: Embolic material delivery devices and methods of using them are disclosed. An example embolic material delivery assembly includes an outer member having a lumen extending therein and a distal end region, an inner member disposed within the lumen of the outer member, wherein the inner member includes a first lumen extending therein. The embolic material delivery assembly also includes a first embolic material extending within the first lumen of the inner member, the embolic material having a first distal end region. The embolic material delivery assembly also includes an anchor disposed within the lumen of the outer member, the anchor having a first attachment region. Further, the first distal end region of the first embolic material is coupled to the first attachment region of the anchor.

Abstract: A medical device system may include an elongate shaft having a lumen extending from a proximal end to a distal end, a proximal release wire, and a distal release wire. The proximal release wire may extend distally from a proximal end configured to remain outside the body to a distal end and may be slidably disposed within the lumen of the elongate shaft. The proximal release wire may include a distal stopper coupled to the distal end thereof. The distal release wire may extend distally from a proximal end to a distal end and may be slidably disposed within the lumen of the elongate shaft. The proximal end of the distal release wire may be slidably coupled to the distal end of the proximal release wire. The distal release wire may be configured to releasably attach a medical device to the distal end of the elongate shaft.

Abstract: A medical device system may include an elongate shaft having a lumen extending from a proximal end to a distal end, a release wire disposed within the lumen of the elongate shaft configured to releasably attach a medical device to the distal end of the elongate shaft, and a securement member releasably coupled to the proximal end of the elongate shaft and fixedly attached to a proximal end of the release wire. A proximal portion of the securement member may be configured to translate proximally away from the proximal end of the elongate shaft upon application of a proximally-directed force to the proximal portion of the securement member and radially inward directed force to the distal portion of the securement member while the elongate shaft is maintained in a fixed position.

Abstract: The present disclosure relates to the field of embolic coil delivery. In particular, the present disclosure provides a delivery system that allows an embolic coil, retained on a delivery tube outside of the microcatheter, to be positioned within a target occlusion area of a patient prior to being controllably deployed, or retracted into the microcatheter for repositioning. The delivery system is particularly useful for minimizing embolic coil kickback.
