Abstract
Various aspects of the instant disclosure relate to flow devices including filters and occluders for modifying flow in body conduits such as blood vessels. In some examples, such devices include a support structure and a flow media coupled to the support structure. The medical device generally further includes one or more capture features. In some examples, the capture features are coupled to the support structure at one or more of the proximal and distal ends of the support structure. In various examples, the capture features facilitate retrograde and antegrade deployment of the medical device and retrograde and antegrade capture of the medical device.
Claims15
A medical device comprising:
- a support structure that is collapsible and has a proximal portion, a distal portion, and an intermediate portion situated between the proximal portion and the distal portion, the support structure comprising a plurality of strut members and at least one capture feature;
- and
- a flow media attached to and covering an outside surface of the strut members from the intermediate portion to the proximal portion of the support structure, the flow media defining a first portion with a first porosity at the intermediate portion and a second portion with a second porosity different from the first porosity,
- wherein all of the plurality of strut members extend diagonally with respect to the first portion of the flow media, the first portion of the flow media terminates at a scalloped edge defined by an undulating series of apex portions and valley portions, and all of the apex portions of the scalloped edge are located at interconnecting sections of the strut members where the strut members interconnect with each other such that the all of the apex portions of the scalloped edge are attached to and supported by the strut members at the interconnecting sections of the strut members.
A medical system comprising:
- a medical device including:
- a support structure that is collapsible and has a proximal portion, a distal portion, and an intermediate portion situated between the proximal portion and the distal portion, the support structure comprising a plurality of strut members and at least one capture feature;
- and
- a flow media attached to and covering an outside surface of the strut members from the intermediate portion to the proximal portion of the support structure, the flow media defining a first portion with a first porosity at the intermediate portion and a second portion with a second porosity different from the first porosity,
- wherein all of the plurality of strut members extend diagonally with respect to the first portion of the flow media, the first portion of the flow media terminates at a scalloped edge defined by an undulating series of apex portions and valley portions, and all of the apex portions of the scalloped edge are located at interconnecting sections of the strut members where the strut members interconnect with each other such that the all of the apex portions of the scalloped edge are attached to and supported by the strut members at the interconnecting sections of the strut members;
- a catheter configured to receive the medical device therein;
- and
- a snare configured to engage the at least one capture feature to retrieve the medical device from both an antegrade direction and a retrograde direction.
