  • Publication number: 20210085920
    Abstract: The present embodiments provide strain relief members for a medical device delivery system, methods of use, and methods of manufacturing. In one embodiment, a medical device delivery system may include a body member with a first end having a first outer diameter, a second end having a second outer diameter, an inner surface facing a lumen that extends axially through the body member along a longitudinal axis, and an outer surface opposite to the inner surface. The embodiment also includes a threaded first connector at the first end of the body member. The outer surface of the body member may include a plurality of depressions. The body member may include a first material. The first connector may include a second material. The first material is more flexible than the second material. A portion of the outer surface of the body member may cover a portion of the first connector.

  • Patent number: 9308008
    Abstract: A surgical bag device is provided. The device includes a surgical bag with a pocket at the open top and elongate biasing member disposed in conjunction with the pocket and translatable between a first open position where the biasing member extends through a substantial portion of a circumference of the pocket, to a second closed position. An elongate push rod with a distal end portion is fixed to the biasing member and an opposite proximal end portion operatively engaged with a movable plunger within a housing. The push rod is translatable as urged by the plunger between a distal position extending the biasing member into the pocket and a proximal position withdrawing the biasing member from the pocket. The push rod comprises a plurality of longitudinally spaced teeth disposed thereon, which are meshingly engagable with a plurality of teeth from a corresponding first set of teeth of a pinion gear.

  • Patent number: 9149177
    Abstract: A medical device is provided. The device includes a generally elongate member with distal and proximal end portions and a longitudinal axis and a lumen disposed therethrough, wherein the lumen is configured to allow the passage of a wireguide therethrough. The proximal end portion defines a trough for accepting a tip of the wireguide and urging the tip into the lumen from a varying angle of attack with respect to the longitudinal axis. The trough is defined from an open proximal end that provides communication with the lumen. The trough includes a proximal end face with an arcuate first edge that traverses only a portion of a total circumference of the elongate member. The proximal end face transitions to a second face disposed distally of the proximal end face. The second face defines a second edge that traverses another portion of the total circumference of the elongate member.
