In one embodiment, an assembly includes a retractor (30, 730, 930) and at least one cylindrical rod (102, 402, 502, 702, 802, 902) attached to the retractor. The rod has a fixed length portion (108, 406, 508, 708, 808, 908) and a spring portion (104, 404, 504, 718, 832, 905). The spring portion of the rod has a longitudinal dimension that changes as a function of loading on the rod. When the rod is in contact with a solid surface such as a bone, it maintains contact with such surface even while changing shape due to loading on the rod. When the assembly includes multiple rods attached to the retractor, both spring-based rods and other types of rods may be used in combination.

Apparatus for endoscopically retracting tissue, the apparatus comprising a sleeve adapted to be slid over the exterior of an endoscope; a balloon movably mounted to the sleeve; and at least one connector extending from the balloon and configured to be secured to tissue which is to be retracted; wherein the balloon is configured to be moved relative to the sleeve in order to retract the tissue.

A tissue retention system to assist in maintaining adipose tissue on a patient in a displaced position during a medical procedure to provide access to a body region of the patient includes an anchor pad having a pad length and a pad width. The anchor pad may include a pad body with an adhesive surface thereon, the adhesive being configured to adhere to a patient's skin. The anchor pad also may include an opposing first attachment surface facing away from the adhesive surface. The tissue retention system also may include a tension member having a second attachment surface.

Apparatuses and methods for use in surgical vascular anastomotic procedures. Apparatus includes a blood vessel inner wall (BVIW) sealing and hole forming device, and a hole forming actuator. BVIW sealing and hole forming device includes a hole sealing device, and an anastomotic hole generating device. Hole sealing device includes a sheath that fully encloses and holds a self-expanding hole sealing assembly, a manual hole sealing controller assembly, and a flexible control wire enclosed within a flexible tube. Anastomotic hole generating device includes outer and inner assemblies, with a conically shaped anastomotic hole generating member. Hole forming actuator includes outer and inner assemblies. Also disclosed are procedures for performing surgical vascular anastomosis using the disclosed apparatuses and methods. Particularly applicable for use in clampless types of (end-to-side) surgical vascular anastomotic procedures, for performing coronary artery bypass grafting (CABG).

The invention relates to a device for reducing the retraction of the edges (4.1) of an opened fascia (4) of a patient (1) having an open soft tissue defect, in particular having an open abdominal wall (2) or an open soft tissue defect on the back, via which a tensile force (A, B) can be applied to the edges (4.1) of the fascia (4) by a force component (A1, B1) directed away from the body of the patient (1), such that the device (11) holds the edges (4.1) of the fascia (4) under tension and spaced apart from each other and that furthermore there is an open soft tissue defect, in particular an opened abdominal wall (2), or an open soft tissue defect on the back. The invention further relates to a kit for treating an open soft tissue defect, in particular of an opened abdominal wall (2) or of an open soft tissue defect on the back, having at least one sponge (9, 15, 28) for filling out an opening (7) of a soft tissue defect, in particular in the abdominal wall or of en open soft tissue defect on the back, and having such a device (11) for reducing the retraction of the edges (4.1) of an opened fascia (4).

A surgical stapler configured to clamp, staple, and cut tissue is disclosed. The surgical stapler comprises a housing, a shaft, a staple cartridge, an expandable anvil, and a distal head portion. The shaft extends from the housing and comprises three concentric actuators. The three concentric actuators are operable independently of each other. The three concentric actuators are actuatable relative to the housing and are configured to perform three separate and distinct end effector functions. The staple cartridge comprises a unitary cartridge body. The distal head portion is configured to rotate relative to the shaft. One of the separate and distinct end effector functions comprises rotating the distal head portion to expand the anvil.

Medical devices and methods of using medical devices are disclosed. An example tissue retraction device includes a first engagement member having a first end and a second end, a second engagement member having a first end and a second end, a first elastic member attached to the second end of the first engagement member, and a first alignment member having a first end, a second end and a lumen extending therethrough. Further, the tissue retraction device has a first length, the first alignment member has a second length, the first elastic member extends within the lumen of the first alignment member and the second length of the first alignment member is less than or equal to the first length of the tissue retraction device.

The present disclosure relates to the field of tissue dissection. Specifically, the present disclosure relates to medical devices which lift and retract tissue during a dissection procedure to improve visualization of the target tissue and mitigate obstruction of dissection tools. In particular, the present disclosure relates to a tissue retraction device which moves from a constrained to relaxed configuration to immobilize and retract the dissected portion of target tissue during a dissection procedure.
