Abstract
A medical grasping device is disclosed. The medical grasping device may be configured to retrieve an object from within a body lumen. A medical grasping device assembly, wherein a portion of the medical grasping device is disposed within a lumen of a delivery sheath, and methods of using the medical grasping device assembly are also disclosed.
Claims16
A medical grasping device for use in an interventional procedure in a body lumen of a patient, the medical grasping device comprising:
- an elongate member;
- a first resilient prong extending from a distal end of the elongate member, the first resilient prong comprising a first engagement feature, wherein the first engagement feature includes a first retaining face oriented at a first angle relative to an extension of a longitudinal axis of the elongate member when the medical grasping device is in an open configuration;
- and
- a second resilient prong extending from a distal end of the elongate member, the second resilient prong comprising a second engagement feature, wherein the second engagement feature includes a second retaining face oriented at a second angle relative to the longitudinal axis of the elongate member when the medical grasping device is in the open configuration;
- wherein the first retaining face is oriented at a third angle relative to the longitudinal axis of the elongate member and the second retaining face is oriented at a fourth angle relative to the longitudinal axis of the elongate member when the medical grasping device is in a closed configuration;
- wherein the first and second angles are obtuse angles as measured from the longitudinal axis, taken from a side of the longitudinal axis opposite the first retaining face to a line extending from the first retaining face which intersects and extends beyond the longitudinal axis;
- and
- wherein the third and fourth angles are acute angles as measured from the longitudinal axis, taken from a side of the longitudinal axis opposite the second retaining face to a line extending from the second retaining face which intersects and extends beyond the longitudinal axis.
A medical grasping device for use in an interventional procedure in a body lumen of a patient, the medical grasping device comprising:
- an elongate member;
- a first resilient prong extending from a distal end of the elongate member, the first resilient prong comprising a first engagement feature formed at a distal end of the first resilient prong;
- and
- a second resilient prong extending from a distal end of the elongate member, the second resilient prong comprising a second engagement feature formed at a distal end of the second resilient prong, wherein a length of the first resilient prong is shorter than a length of the second resilient prong;
- wherein the first engagement feature includes a protuberance extending outwardly from the distal end of the first resilient prong and wherein the second engagement feature includes a slot sized to receive the protuberance such that the protuberance is seated against the slot when the first and second resilient prongs are engaged.
