Abstract: A retrieval device may have a contracted state and an expanded state. The retrieval device may include a sheath and at least three support members. Each of the support members may have a first portion with a first cross-sectional shape and a second portion with a second cross-sectional shape different from the first cross-sectional shape. A proximal end fixed of each of the support members may be coupled to the sheath, and a distal end may be movable relative to the sheath. The retrieval device may further include at least three movable members movable relative to the support members. Each movable member may extend through a lumen of one support member of the at least three support members and through a lumen of a different support member of the at least three support members.

Abstract: According to an aspect, a medical device includes a needle member having a curved portion, a handle coupled to the needle member, and a pusher member including a sheath and an extension member. The sheath may be bendable. The extension member is configured to be slidably coupled to a track of the handle such that extension member slides within the track during a medical procedure. The sheath defines a lumen configured to receive a portion of the needle member. The extension member is configured to be de-coupled from the track of the handle after the medical procedure. The sheath is configured to be de-coupled from the needle member after the medical procedure. In some examples, the sheath of the pusher member is configured to bend to conform to the curved portion when the sheath of the pusher member is moved over the curved portion of the needle member.

Abstract: According to an aspect, a medical device may include an elongated shaft configured to rotate about its longitudinal axis. The elongated shaft may include a retaining area configured to retain an implant. The medical device may include a sheath disposed around a portion of the elongated shaft. The elongated shaft may be configured to move in relation to the sheath. The elongated shaft may be configured to move in a direction parallel to the longitudinal axis between a first position and a second position. When the elongated shaft is in the first position, the retaining area is disposed outside of a cavity defined by the sheath. When the elongated shaft is in the second position, the retaining area is disposed within the cavity defined by the sheath.

Abstract: According to an example of the present disclosure, a retrieval device having a contracted state and an expanded state may include at least three support members each having a lumen, a fixed proximal end, and a movable distal end, and at least two members movable relative to the support members. Each movable member may include a first end and a second end and extending distally through a lumen of a support member and proximally through a lumen of a different support member. The device may include a stop located at the second end of at least one movable member to restrict movement of the second end after moving a distance distally during movement of the retrieval device toward the expanded state.

Abstract: According to an embodiment of the present disclosure, a retrieval device may include a distally located end effector movable between a contracted state and an expanded state. The end effector may include a plurality of support members each including a passage. The end effector may also include a plurality of movable members. A first movable member may include a first portion extending into a first passage of the support member passages. The retrieval device may also include a proximally located handle assembly including a longitudinal actuator and a twisting actuator coupled to the plurality of movable members. The longitudinal actuator and twisting actuator may be configured to longitudinally move and twist the movable members without longitudinally moving and twisting the support members.

Abstract: A suturing instrument for placing multiple sutures include an elongate body engaged to a handle. A suturing head extends from a distal end of the elongate body, and the suturing head is articulable relative to the elongate body. Both a first needle carrier and a second needle carrier are movable into and out of the suturing head. A first actuator allows controlled movement of the first needle carrier, and this first actuator extends from a proximal end of the handle. A second actuator allows controlled movement of the second needle carrier, and this second actuator also extends from the proximal end of the handle. The suturing head can be articulated within a range of about 0 degrees to about 30 degrees, as measured from a longitudinal axis running along the length of the elongate body, and this variable articulation angle of the head allows deployment of the first needle carrier and the second needle carrier at various orientations with respect to the longitudinal axis.

Abstract: The invention discloses an implant. The implant may include a first flap and a second flap. The first flap may further include a first portion, a second portion and a transition region. The first portion may be configured to be attached proximate a sacrum. The second portion may be configured to be attached to an anterior vaginal wall. The transition region lies between the first portion and the second portion. The second flap may be fabricated such that a portion of the second flap is configured to be attached to a posterior vaginal wall. The implant may be configured such that a value corresponding to a biomechanical parameter defining a biomechanical attribute of the portion of the first flap attaching to the anterior wall is different from a value of the biomechanical parameter defining the biomechanical attribute of the portion of the second flap attaching to the posterior wall.
