摘要： A device for collecting a tissue sample includes an outer needle extending longitudinally from a proximal end to a distal end and including a lumen extending therethrough. The device also includes an inner needle extending longitudinally from a proximal end to a distal end and including an opening extending laterally in and along a length thereof. The inner needle is sized and shaped to be slidably received within the lumen of the outer needle and movable relative thereto between an insertion configuration, in which the opening is covered by the outer needle, to a tissue collecting configuration, in which the opening is exposed. In addition, the device includes a handle assembly for adjusting a throw length of the inner needle relative to the outer needle.

摘要： A medical device may include a plurality of links reciprocally movable between a loose configuration having a first rigidity and a compact configuration having a second rigidity greater than the first rigidity, wherein application of a force to a distalmost link of the plurality of links when the plurality of links are in the loose configuration causes the plurality of links to change orientation relative to one another, and application of the force to the distalmost link when the plurality of links are in the compact configuration does not cause the plurality of links to change orientation relative to one another.

摘要： The present disclosure is directed to a valve structure that comprises a flexible structure having a distal portion configured for attachment to a first member and a proximal portion configured for attachment to a second member. The flexible structure is configured such that when the first member is extended distally relative to the second member, the flexible structure adopts a reduced width profile and such that when the first member is retracted proximally relative to the second member to a point of maximal retraction, the flexible structure adopts an expanded width profile, which is more resistant to deformation due to fluid pressure in a proximal direction than it is to deformation due to fluid pressure in a distal direction. The present disclosure is also directed to devices and methods pertaining to such a valve structure.

摘要： A method for treating an intestine with an expandable scaffolding expanded within the intestine. After placing the expandable scaffolding at a target location, such as across a fistula, the first and second end portions of the expandable scaffolding are radially expanded such that the first and second end portions contact an inner surface of the intestine on opposing sides of the fistula, anchoring the first and second end portions to the intestine. Radially expanding the first and second end portions foreshortens the medial portion along the longitudinal axis such that the first and second end portions are drawn closer together along the longitudinal axis as the medial portion foreshortens to close the fistula.

摘要： A spring element for a contact force sensing medical catheter. The spring element includes a first ring, a second ring spaced apart from the first ring, a plurality of struts connecting the first ring to the second ring, and a plurality of interlocking features. The second ring and the first ring are coaxially aligned with a longitudinal axis of the spring element. The plurality of struts is configured to permit elastic, relative axial and radial displacement between the first ring and the second ring. The plurality of interlocking features is configured to limit the relative axial and radial displacement between the first ring and the second ring.
