Medical device handles and related methods of use

A medical device, comprising:

• a sheath including a lumen, a distal end, and a proximal end;
• an end-effector unit and an elongate member connected to the end-effector unit and extending proximally from the end-effector unit within the lumen of the sheath, the end-effector unit and the sheath movable relative to each other to achieve a first state of the end-effector unit and a second state of the end-effector unit;
• and
• a handle comprising:
• a first handle portion connected to the proximal end of the sheath
• a second handle portion connected to the proximal end of the elongate member, and
• a biasing member longitudinally aligned with the sheath between the first handle portion and the second handle portion to hold the first handle portion and the second handle portion in a spaced apart position,
• wherein the first and second handle portions are configured such that relative movement of the first handle portion towards the second handle portion causes the end-effector to move between the first state and the second state.

• and
• a handle comprising:
• a first handle portion connected to the proximal end of the sheath,
• a second handle portion connected to the proximal end of the elongate member, and
• a compliant member longitudinally aligned with the sheath between the first handle portion and the second handle portion, wherein the compliant member defines a compliant member lumen extending therethrough, and wherein at least one of, the elongate member and sheath are disposed within the compliant member lumen,
• wherein the first and second handle portions are configured such that relative movement of the first handle portion towards the second handle portion causes the end-effector to move between the first state and the second state.

• a second handle portion connected to the proximal end of the elongate member, wherein the second handle portion is distal of the first handle portion, and
• a compliant member longitudinally aligned with the sheath between the first handle portion and the second handle portion to hold the first handle portion and the second handle portion in a spaced apart position,
• wherein the first and second handle portions are configured such that relative movement of the first handle portion towards the second handle portion causes the end-effector to move between the first state and the second state.
