Methods and devices for accessing and retracting a capsule of a joint
Devices and methods are disclosed herein for accessing the hip joint. A first device can be securely attached to the capsule of a joint. The first device can tent the capsule to increase the volume of the peripheral compartment. A second device can be biased against the first device to pierce the tented capsule and create a portal. Devices and methods are also disclosed herein for distending the capsule of a joint. A distention device may access a portal established within the capsule. The distention device can expand the capsule by applying an expansive force within the peripheral compartment. The distention device can maintain distention of the peripheral compartment while other devices access the joint.
1. A method for distending a capsule of a joint, the method comprising:
accessing a capsule of a joint;
creating a first portal and a second portal through the capsule;
guiding a magnetic end of a first flexible strap into the first portal;
guiding a magnetic end of a second flexible strap into the second portal, the magnetic ends coupling within the capsule;
withdrawing either the first or second strap from the capsule to place a mid-portion of the other of the first or second strap within the capsule; and
pulling on the non-withdrawn first or second strap from both portals to distend the capsule away from the joint.
2. The method of claim 1 , wherein the portals are connected to a first cannula and a second cannula.
3. The method of claim 1 , wherein the magnetic ends are manually guided to each other by manipulating one or both of the first and second straps.
4. The method of claim 1 , wherein tension is maintained on the non-withdrawn first or second strap to continually distend the capsule for a following procedure.
5. A method for distending tissue, the method comprising:
creating a first portal and a second portal through the tissue;
guiding a first magnetic end of a first flexible strap through the first portal;
guiding a second magnetic end of a second flexible strap through the second portal;
coupling the first magnetic end of the first flexible strap to the second magnetic end of the second flexible strap;
withdrawing either the first magnetic strap from the first portal or the second magnetic strap from the second portal so as to place the other of the first flexible strap or the second flexible strap through both the first portal and the second portal; and
pulling on the other of the first flexible strap or the second flexible strap so as to distend the tissue.
6. The method of claim 5 , wherein the first portal is connected to a first cannula and the second portal is connected to a second cannula.
7. The method of claim 5 , wherein the first and second magnetic ends are manually guided to each other by manipulating one or both of the first and second flexible straps.
8. The method of claim 5 , wherein tension is maintained on the other of the first flexible strap or the second flexible strap to continually distend the tissue for a following procedure.
