Abstract
Among other things, methods and apparatus for inserting devices for closing tissue openings are disclosed. Examples may include a handle, sheath and/or sleeve for insertion into a patient and through or adjacent a tissue defect, fistula, or other tissue opening to be closed. Winding mechanisms for operation in or with such inserting devices are also described.
Claims11
An apparatus for inserting a device into a patient to close a tissue opening in the patient, comprising:
- a handle portion having a gripping portion with an external surface for gripping by a user, a lumen extending through the gripping portion, and a cap;
- a sleeve having a proximal end and a flange at the proximal end, the sleeve defining a lumen;
- and
- a sheath portion having a proximal end portion and an elongated tubular member extending from the proximal end portion, a lumen extending through the proximal end portion and the elongated tubular member, and a cap for connecting to the cap of the handle portion for selective connection and separation of the sheath portion and handle portion;
- wherein the elongated tubular portion of the handle portion extends at least partially through the lumen of the sheath portion, and the elongated tubular member of the sheath portion extends at least partially through the lumen of the sleeve, and wherein the sleeve and tubular member of the sheath portion are slidable with respect to each other along each other;
- and further comprising a closure device having an internal member for sealing or anchoring and a filament connected to the internal member, the internal member being initially within the sheath portion and the filament initially extending through at least a portion of the lumen of the sheath portion and the lumen of the handle portion.
A method of inserting a closure device into a patient for closing an undesirable tissue opening, comprising:
- inserting an apparatus into the patient, wherein the apparatus includes a handle portion with a gripping portion and a distal cap, wherein a lumen extends through the gripping portion and cap, a sleeve defining a lumen and having a proximal end and a flange at the proximal end, and a sheath portion having a proximal end portion with a cap and an elongated tubular member extending from the proximal end portion with a lumen extending through the proximal end portion and the elongated tubular member, and wherein the distal cap of the handle portion is selectively connectable to and separatable from the cap of the sheath portion, and the elongated tubular member of the sheath portion extends at least partially through the lumen of the sleeve, and wherein the sleeve and tubular member of the sheath portion are slidable with respect to each other along each other;
- pulling the handle portion so that the handle portion moves proximally with respect to the sleeve, so as to engage an anchoring member with tissue adjacent the undesirable tissue opening, the anchoring member connected to a filament that extends proximally through the handle portion;
- and
- severing the connection between the filament and the anchoring member.
