Abstract
A medical apparatus that includes a distal member, a needle disposed in the distal member and proximally advanceable from the distal member, and a needle capture portion positioned proximal to the distal member and which includes a through-hole to direct the needle from the needle capture portion towards a graspable member at a trajectory narrower than a trajectory of the needle from the distal member to the needle capture portion.
Claims20
A medical apparatus comprising:
- a distal member;
- a plurality of needles disposed in the distal member and proximally advanceable from the distal member;
- a first guide proximal the distal member, the first guide configured to direct the plurality of needles in a first trajectory;
- and
- a second guide proximal the first guide, the second guide configured to route the plurality of needles in a second trajectory towards a proximal end of the medical apparatus, the second trajectory being different from the first trajectory.
A medical apparatus comprising:
- a distal member comprising a tapered distal end;
- a plurality of needles disposed in the distal member and proximally advanceable from the distal member, each of the plurality of needles comprises a sharpened tip section and an elongate shank portion, the plurality of needles cooperating with a needle actuator to move the plurality of needles toward a handle;
- a first guide proximal the distal member, the first guide configured to direct the plurality of needles in a first trajectory;
- and
- a second guide proximal the first guide, the second guide configured to receive the plurality of needles and route the plurality of needles in a second trajectory towards a proximal end of the medical apparatus, the second trajectory being different from the first trajectory.
A method for suturing an accessed opening, the method comprising:
- positioning a medical apparatus adjacent the opening, the medical apparatus comprising:
- a distal member;
- a plurality of needles disposed in the distal member and proximally advanceable from the distal member;
- a first guide proximal the distal member, the first guide configured to direct the plurality of needles in a first trajectory;
- and
- a second guide proximal the first guide, the second guide configured to route the plurality of needles in a second trajectory towards a proximal end of the medical apparatus, the second trajectory being different from the first trajectory;
- advancing the distal member through the opening to dispose the distal member on an opposite side of the opening from the second guide;
- and
- manipulating a graspable member to withdraw the plurality of needles through tissue surrounding the opening and toward the proximal end of the medical apparatus, the plurality of needs being guided in the first trajectory by the first guide and in the second trajectory by the second guide.
