摘要： A system for retrieving an implanted medical device includes an outer tubular member and a contractible super-elastic net, which may be joined to an elongate shaft that extends in sliding engagement within the outer tubular member. When the net expands from a contracted condition the net defines a longitudinally extending tubular cavity. An open end of the cavity is sized to receive passage of a housing of the device therethrough; and the net, with the device housing contained therein, forms an interference fit within an inner diameter of the outer tubular member. But, an outer diameter of the net, in a fully expanded condition, is larger than the inner diameter.

摘要： A delivery system for an implantable medical device includes a tool and a tethering member extending side-by-side within an inner shaft thereof; the tool extends within a first lumen, being in sliding engagement therein, and includes a distal end coupling feature that protrudes from a distal end of the inner shaft; and the tethering member has a first segment extending within a second lumen, and a second segment extending from the first segment and distally from the distal end of the inner shaft to an end of the tethering member, which is configured to engage with a holding member of the device, and with which the coupling feature of the tool is configured to couple. A retainer may be joined to another end of the tethering member that protrudes from a proximal port of the system.

摘要： An improved assembly for securing an implantable medical device for retrieval from an implant site includes a plurality of snares, wherein distal openings of a first snare carrier lumen and a second snare carrier lumen have a pre-set offset established therebetween. First and second snare shafts, to which first and second snare loops are coupled, respectively, extend within the corresponding snare carrier lumens such that each loop is located in proximity to the corresponding distal opening of the lumen. The pre-set offset allows an operator to simultaneously position the snare loops around the device; and, when the operator retracts the snare shafts to collapse the snare loops until the loops fit snuggly around the device, the pre-set offset can help to align the device for retrieval.

摘要： A catheter inner assembly includes a receptacle with an interior contour configured to mate with a head and neck contour of a holding member of an implantable medical device; and a laterally facing opening of the receptacle has a profile matching a longitudinal profile of the head and neck. Thus, the opening allows only a properly oriented passage of the holding member therethrough, the passage being without deformation of holding member or opening. The inner assembly further includes a lock and release member useful for securing the device to the catheter, when the holding member has been passed through the receptacle's opening to mate with the receptacle's interior contour. The lock and release member may include an arcuate sidewall moveable between a first location, at which the sidewall overlays the laterally facing opening, and a second location, at which the sidewall is located proximal to the opening.

摘要： An engagement subassembly of a catheter, for retrieving an implanted medical device, may include at least three segments or, alternately, capture members being spring biased outward from a longitudinal axis of the subassembly, wherein a device receptacle of the catheter forces the capture members/segments, against the spring bias thereof, toward the axis. Each capture member includes a spring-biased wire and a grip, which is located between proximal and distal portions of the corresponding wire, and which is configured to interlock within a gap between a device attachment feature and housing; a length of each wire distal portion may be approximately equal to that of the device housing. An interlocking edge of each segment interlocks within the gap between the attachment feature and housing, when a distal-facing surface of each segment, which tapers outward from the axis in a distal direction, comes into confronting engagement with the device housing.

摘要： In a system for retrieving an implanted device, a flared inner surface of a catheter tubular sidewall may define a distal-most opening of a device receptacle; the opening has a first diameter equal to that of the receptacle, and a second diameter, coincident with a distal-most edge of the tubular sidewall, and at least 5% greater than the receptacle diameter. Alternately, a retrieval tool in sliding engagement within a lumen of a catheter includes a shaft assembly, through which a snare member passes, and which includes a collapsible spring-biased perimeter sidewall; the sidewall defines a capture member passageway approximately coaxial, and in fluid communication with a lumen of the shaft assembly. A distal-most opening of the passageway has a spring-biased diameter that is greater than that of a distal-most opening of a device receptacle of the catheter, and a collapsed diameter that is less than the receptacle distal-most opening diameter.

摘要： A device receptacle of a catheter resides in a sidewall thereof, which includes a proximal section, a central section extending distally from the proximal section, and a distal section extending distally from the central section. A length of the central section is approximately 30% of an overall length of the sidewall; the proximal and distal sections have approximately the same stiffness; and a stiffness of the central section, formed from a polymer material without any structural reinforcement or any other member embedded therein, is significantly less than that of the proximal and distal sections. When an operator causes the receptacle sidewall to buckle, a distal opening of a chamber of the receptacle becomes aligned with an implanted device so that the operator can bring the implanted device into the chamber to retrieve the device from the implant site.

摘要： An operator can release a looped portion of a tethering member, which terminates a distal section thereof, from being secured within a locking lumen of a delivery catheter shaft, and then move the distal section out of engagement with an attachment feature of an implantable medical device to untether the device from the catheter. The tethering member extends within another lumen of the shaft, which may be part of a catheter assembly that further includes a locking member extending within the locking lumen and having a distal tip located in proximity to an aperture of the shaft. To tether the device to the catheter, the operator can engage the tethering member distal section with the device attachment feature, and then pass the looped portion thereof through the aperture and into the locking lumen, where the locking member distal tip can be passed through the looped portion to secure it.

摘要： A tether assembly for a delivery tool that deploys an implantable medical device includes an elongate shaft and an attachment member coupled to a distal end of the shaft, wherein the attachment member includes an external thread and an end wall, the end wall extending orthogonally with respect to a direction of travel within a valley of the external thread to provide a hard stop for a threaded attachment bore of the medical device, when the bore is mated with the external thread. The tether assembly may extend within a lumen defined by an elongate tube of an inner assembly of the delivery tool, such that the attachment member thereof is located in proximity to a distal member of the inner assembly, the distal member being coupled to a distal end of the tube and forming a distal opening of the lumen.
