said diaper being contoured by longitudinally opposite end portions extending in a transverse direction outside longitudinally opposite ends of said core and transversely opposite side edge portions extending in a longitudinal direction outside transversely opposite side edges of said core wherein said front and rear waist regions are connected to each other by means of fastening means when the diaper is put on; and
of said front and rear waist regions, at least said rear waist region including an elastically stretchable waist area extending in the transverse direction along its end and elastically stretchable wing areas extending outward from its transversely opposite side edge portions in the transverse direction, said transversely opposite side edge portions of said rear waist region lying between said stretchable waist area and said stretchable wing areas and said stretchable wing areas having a transverse stretch stress higher than that of said stretchable waist area.
2. The diaper according to claim 1, wherein the stretchable elasticity of said elastically stretchable waist area is created by a first elastic member contractibly attached to said waist region along its end and the stretchable elasticity of said elastically stretchable wing areas is created by stretchy sheets separately of said top- and backsheets.
3. The diaper according to claim 1, wherein said elastically stretchable waist area presents a transverse stretch stress in a range of 0.5 to 3.0 N as said elastically stretchable waist area is shortened to a transverse length dimension corresponding to 90% of a second length dimension of said elastically stretchable waist area as maximally stretched in the transverse direction and set as 100%, each of said elastically stretchable wing areas presents a transverse stretch stress in a range of 1.5 to 7.0 N as each of said elastically stretchable wing areas is stretched to a transverse length dimension corresponding to 120% of a second length dimension of said elastically stretchable wing areas as non-stretched in the transverse direction and set as 100% and presents a transverse stretch stress in a range of 3.0 to 10.0 N as each of the elastically stretchable is stretched to a transverse length dimension corresponding to 150% of said second length dimension of said elastically stretchable wing areas as non-stretched in the transverse direction and set as 100%.
4. The diaper according to claim 1, wherein the transversely opposite side edge portions of said rear waist region are substantially non-stretchable.
5. The diaper according to claim 1, wherein second elastic members contractibly attached to the transversely opposite side edge portions of said rear waist region make said transversely opposite side edge portion stretchable in the transverse direction and the transverse stretch stress of said elastically stretchable wing areas is lower than the transverse stretch stress of the transversely opposite side edge portions of said rear waist region.
6. The diaper according to claims 1, wherein the transversely opposite side edge portions of said rear waist region present a transverse stretch stress in a range of 5 to 20 N as said side edge portions are stretched to a length dimension corresponding to 90% of a third length dimension of said side edge portions maximally stretched in the transverse dimension and set as 100%.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method of accessing an anatomic space of a patient comprising:
advancing a tubular access sleeve having a working lumen and a suction tool lumen through an opening in the patient to dispose a distal end of the sleeve adjacent tissue enclosing the anatomic space;
advancing a suction tool comprising suction ports through the suction tool lumen to extend the suction ports distally from the sleeve; and
applying suction through the suction ports to grasp the tissue, whereby the anatomic space may be accessed through the working lumen.
2. The method of claim 1 further comprising the step of advancing a cutting tool through the working lumen and cutting through the tissue while suction is applied through the suction ports to grasp the tissue.
3. The method of claim 1 wherein the suction tool comprises a suction pad mounted to a support arm branching from a suction tool trunk, the suction pad comprising at least a portion of the suction ports.
4. The method of claim 3 wherein the suction tool further comprises a second suction pad mounted to a second support arm branching from the suction tool trunk, the second suction pad comprising at least a portion of the suction ports.
5. The method of claim 4 further comprising:
advancing a cutting tool through the working lumen;
creating an incision in the tissue while suction is applied through the suction ports of the suction pads to grasp the tissue; and
moving the suction pads apart to tension the tissue and widen the incision, whereby the anatomic space may be accessed through the incision.
6. The method of claim 1 wherein the step of advancing a tubular access sleeve includes the step of disposing the distal end of the sleeve adjacent pericardial tissue.
7. The method of claim 1 including the step of making a subxiphoid opening and advancing the tubular access sleeve through the subxiphoid opening.
8. The method of claim 1 including the step of making an intercostal opening and advancing the tubular access sleeve through the intercostal opening.
9. The method of claim 1 including the step of making a transthoracic opening and advancing the tubular access sleeve through the transthoracic opening.
10. The method of claim 1 further comprising the step of advancing a medical device through the lumen, wherein the medical device is selected from the group consisting of an electrosurgical tool, a thoracoscope, an endoscope, a lead, an electrode, a catheter, a guidewire and a cutting instrument.
11. The method of claim 1 further comprising the step of delivering a drug through the working lumen to the anatomic space.
12. The method of claim 1 further comprising the step of delivering a diagnostic agent through the working lumen to the anatomic space.
13. A system for accessing an anatomic space of a patient comprising:
a tubular access sleeve having a working lumen and a suction tool lumen; and
a suction tool disposed within the suction tool lumen comprising suction ports coupled to a support arm extending distally from a tool trunk, wherein the suction ports are deployable distally from the sleeve.
14. The system of claim 13 wherein the suction tool comprises a suction pad coupled to the support arm, the suction pad comprising at least a portion of the suction ports.
15. The system of claim 14 wherein the suction tool further comprises a second suction pad coupled to a second support arm extending distally from the tool trunk, the second suction pad comprising at least a portion of the suction ports.
16. The system of claim 15 wherein the suction tool further comprises a suction lumen extending from the suction pads through the support arms and through the suction tool trunk to a proximal end of the trunk.
17. The system of claim 16 further comprising a suction fitting at the trunk proximal end communicating with the suction lumen, the suction fitting being capable of being coupled to an available surgical operating room vacuum source.
18. The system of claim 13 wherein the suction ports are housed within the working lumen by proximal retraction of the suction tool trunk and are deployable distally from the working lumen upon distal advancement of the suction tool trunk within the suction tool lumen.
