The snare loop has a first portion connected to a distal end of the support truss and a second portion connected to the distal end of the actuation member. | 12-25-2014 |
20140378989 | RESECTION DEVICES AND RELATED METHODS OF DEPLOYMENT - A medical/surgical device for performing tissue resection can include an endoscope with proximal and distal ends, defining working channels, and a snare assembly located in one of the working channels. The working channel may include a bend near the distal end and towards the outward radial wall of the endoscope. The snare assembly may include a snare loop and an actuation element imparted with the pre-formed angular bends and an actuation control handle. The bends of the actuation element and the working channel may be the same. The rotational manipulation of the actuation element may synchronize the pre-formed bend of the actuation element with the bend of the working channel to concentrically (or otherwise) align the deployed snare loop with the endoscope or endoscope attachments. | 12-25-2014 |
20140379004 | Hemostasis Device With One Way Trap - A tissue clipping device includes (a) a first body extending from a proximal end to a distal end and including a first channel extending therethrough and (b) a plurality of first arm elements, each of the plurality of first arm elements extending radially into the first channel from a first end coupled to the first body to a second end proximal of its first end so that tissue drawn into a distal end of the first channel proximally beyond the second end of the plurality of first arm elements is compressed between each of the plurality of first arm elements and retained in the first channel. | 12-25-2014 |
20150057681 | DEVICES AND METHODS FOR LUMEN OCCLUSION - A system may include an introducer sheath including a retention member configured to anchor the introducer sheath in a natural body lumen having a wall. The system may also have an elongate member extending along a longitudinal axis through a working channel of the introducer sheath. Additionally, the system may have a manipulating portion coupled to a distal end of the elongate member. The manipulating portion may include at least one selectively actuatable member configured to transition between an undeployed configuration and a deployed configuration. In the undeployed configuration, the at least one actuatable member may extend substantially parallel to the longitudinal axis and in at least one position in the deployed configuration, the at least one actuatable member may extend radially outwardly from the longitudinal axis. In the deployed configuration, the manipulating portion and elongate member may be configured to be proximally retracted toward the working channel of the introducer sheath so as to move a distal portion of the wall towards a proximal portion of the wall. | 02-26-2015 |
