An embolic implantation system configured to deliver an embolic implant intravascularly to a treatment site includes an elongated delivery tube to which the embolic implant is detachably attached by a flexible loop extending through a retaining ring or opening on the embolic implant and an elongated detachment member or pull wire extending through the delivery tube and flexible loop. The pull wire has a bump near its distal end that inhibits the pull wire from moving further distally when the bump presses distally against the flexible loop and/or retaining ring. The flexible loop and retaining ring thereby serve as a distal obstruction obstructing distal movement of the bump and thereby distal movement of the pull wire into the implant.

A medical device configured for assistance with the cervical cerclage procedure is provided. The medical device includes a barrier structure with a finger and a therebetween. A hub is fixed to a distal end of the catheter and defines an extension with a second void between an end surface of the hub and the extension. The barrier structure and the hub are releaseably attached with the extension disposed within the first void and the finger within the second void. A wire guide withdrawably extends through coaxial holes within the hub, extension, finger, and a portion of the barrier structure to fix the hub and barrier structure together.

A non-transitory computer readable medium containing instructions that when executed by at least one processor, cause the at least one processor to perform operations for monitoring partitioning of a medical instrument during an endovascular procedure. The operations may further be configured to obtain an input to activate a partitioning mechanism associated with a medical instrument within a lumen of a catheter, the catheter being positioned within a body. Further, embodiments may be configured in response to the input, to activate the partitioning mechanism. The operations may further be configured, following the activation, to obtain partitioning outcome data. The operations may determine, based on the partitioning outcome data, whether the medical instrument may be in a severed state or a connected state. The operations may, if the severed state of the medical instrument is detected, output a success notification. Some embodiments may be configured, if the connected state of the medical instrument is detected, to output at least one of (i) a control signal to vary activation of the partitioning mechanism or (ii) an instruction to reposition the medical instrument relative to the partitioning mechanism.

The present invention introduces a material, i.e. a device, which is insertable into a vein of a outer parts of a sheath, two-sidedly adhesive tubular material with a supporting material and protrusions, either a balong or an inner protective film, and a control cable for the insertion and extraction of the device along the vein. The supporting material may be compressed initially, and after removal of the outer part of the sheath, the supporting material with protrusions will expand towards the vein walls. After removal of the inner part of the sheath and the control cable, the treated vein area can be manually pressed on top of the skin, thus closing the vein through inner and outer adherence of the material. The protrusions may have a barbed shape.

An apparatus is configured to be implanted within a biological lumen. The apparatus includes a plurality of magnetic elements and a coupling body. The magnetic elements are arranged in an annular array extending form an axis. The annular array defines an occludable opening configured to transition between an occluded state and an opened state. The magnetic elements include a first magnetic element and a second magnetic element. The second magnetic element is located adjacent to the first magnetic element. The second magnetic element includes a polymer magnetic material formed in a shape designed to geometrically interlock with the first magnetic element in the occluded state. The second magnetic element is configured to elastically deform to transition the occludable opening from the occluded state to the opened state. The coupling body is configured to affix to a portion of the first magnetic element and a portion of the second magnetic element.

An apparatus is configured to be implanted within a biological structure. The apparatus includes an annular retaining assembly and an occlusion member. The annular retaining assembly defines an annular opening and includes an outer ring and an inner ring. The outer and inner rings are disposed about a central axis. The outer ring also has an outer wall, an inner wall, and a bio-absorbable material. The inner ring defines an annular opening and is attached to the inner wall of the outer ring. The inner ring also includes a surface to promote tissue in-growth. The occlusion member extends from the annular retaining assembly toward the central axis. The occlusion member also includes a plurality of magnetics. The occlusion member is magnetically biased to a first position that substantially occludes the annular opening. The occlusion member is configured to elastically deform to a second position that substantially unblocks the annular opening.

A catheter includes a detachable tip assembly that when detached from the catheter may be used to occlude a body lumen or vessel. The detachable distal tip assembly may include an inflatable balloon disposed over and secured to a tubular member. The inflatable balloon may be in fluid communication within an inflation lumen extending within the catheter body. Upon reaching a target site within a body lumen or vessel, the detachable distal tip assembly may be released from the distal end of the catheter upon inflation of the balloon to a predetermined size.

An embolic device deployment system having a lumen with proximal and distal ends. An embolic device having a proximal retaining ring and an expandable member having a contracted and expanded state, with two apertures. The expandable member is disposed in the lumen in the expanded state. An engagement member has a distal loop extending through the retaining ring and a proximal loop extending into the lumen. The detachment member slides within the lumen and another of the apertures and is disposed through the loops. It comprises a bump on the detachment member between the loops. When the detachment member is in the distal loop and the distal loop is disposed within the retaining ring, the embolic device is in an engaged position. Pulling the detachment member withdraws it from the distal loop. The bump contacts the proximal loop to assist in the disengagement of the distal loop from the retaining ring to release the embolic device.

A catheter includes a detachable tip assembly that when detached from the catheter may be used to occlude a body lumen or vessel. The detachable distal tip assembly may include an inflatable balloon disposed over and secured to a tubular member. The inflatable balloon may be in fluid communication within an inflation lumen extending within the catheter body. Upon reaching a target site within a body lumen or vessel, the detachable distal tip assembly may be released from the distal end of the catheter upon inflation of the balloon to a predetermined size.

A system and method for retrieving an implantable device includes a delivery catheter, a recapture section, and a sheath. The delivery catheter has a proximal end and a distal end. The recapture section is axially extendable from the distal end of the delivery catheter. The sheath has a proximal end and a distal end and a lumen sized to receive the delivery catheter. A portion of the lumen of the sheath is actuatable from an enlarged inside diameter to a reduced inside diameter to apply an inwardly directed force to the recapture section. The delivery catheter can be actuated with respect to the sheath to extend or retract the recapture section with respect to the delivery catheter.
