Compressible non-fibrous adjuncts
Stapling assemblies for use with a surgical stapler are provided. In one exemplary embodiment, the stapling assembly includes a cartridge having a plurality of staples disposed therein and a non-fibrous adjunct formed of at least one fused bioabsorbable polymer and configured to be releasably retained on the cartridge. Adjunct systems for use with a surgical stapler are also provided. Surgical end effectors using the stapling assemblies are also provided. Methods for manufacturing stapling assemblies and using the same are also provided.
Layer of material for a surgical end effector
A staple cartridge comprising a tissue thickness compensator is disclosed. The tissue thickness compensator comprises an external layer and tubular elements. The tubular elements are interconnected and positioned within the external layer. The tubular elements comprise apertures defined therein and the tubular elements are configured to collapse as pressure is applied to the tissue thickness compensator by tissue during the firing motion. The apertures enable fluids from the tissue to permeate the tissue thickness compensator.
Systems and methods for selectively occluding the superior vena cava for treating heart conditions
Systems and methods and devices are provided for treating conditions such as heart failure and/or pulmonary hypertension by at least partially occluding flow through the superior vena cava for an interval spanning multiple cardiac cycles. A catheter with an occlusion device is provided along with a controller that actuates a drive mechanism to provide at least partial occlusion of the patient's superior vena cava, which reduces cardiac filling pressures, and induces a favorable shift in the patient's Frank-Starling curve towards healthy heart functionality and improved cardiac performance. The occlusion device may include a lumen obstructed by a relief valve that may permit fluid flow through the occlusion device to release an excessive build-up of pressure.
Skin surface indwelling device for guiding punctures
A skin surface indwelling device for guiding punctures includes: an indwelling tube (13) having an inside tunnel (P) substantially extending along the longitudinal direction of the indwelling tube (13), the tunnel (P) is used for guiding needle (N), the indwelling tube (13) has a proximal end positioned above the skin surface (S) and a distal end positioned under the skin surface (S) in indwelling state; a support (11) having a bottom surface on its bottom that directly or indirectly contacts with the skin surface (S), the support (11) supports and fixates the indwelling tube (13); and a sealing elements (141,142) configured to seal the tunnel (P). The skin surface indwelling device for guiding punctures can shorten the time of establishing a puncture tunnel in the buttonhole puncture method, and help to build the puncture tunnel. In addition, the skin surface indwelling device can also guide the puncture needle (N) when puncturing, and protect the immature puncture tunnel.
Compressible non-fibrous adjuncts
Stapling assemblies for use with a surgical stapler are provided. In one exemplary embodiment, the stapling assembly includes a cartridge having a plurality of staples disposed therein and a non-fibrous adjunct formed of at least one fused bioabsorbable polymer and configured to be releasably retained on the cartridge. Adjunct systems for use with a surgical stapler are also provided. Surgical end effectors using the stapling assemblies are also provided. Methods for manufacturing stapling assemblies and using the same are also provided.
Skin morphing and tension distributing system for external fixation and methods of use thereof
Kits and systems are disclosed that include one or more segments of elastically deformable membrane in combination with one or more external fixation members and optionally in combination with one or more tension protector pads. Also disclosed are methods of use of the kits and systems in methods that involve stretching the elastically deformable membrane and applying the stretched membrane to the skin of a patient, and releasing the tension on the membrane, thus causing compression of the skin to which the membrane is applied. The method may further include the optional steps of inserting one or more external fixation members through the membrane/skin combination and into a bone segment, applying a distraction force to the one or more external fixation members, and separating at least a portion of the membrane so as to release a portion of the tension in the skin at a rate that is similar to a rate at which the distraction force is applied.
SYSTEMS AND METHODS FOR USING STRUCTURED TISSUE AUGMENTATION CONSTRUCTS IN SOFT TISSUE FIXATION REPAIR
Devices, systems, and methods to improve both the reliability of soft tissue repair procedures and the speed at which the procedures are completed are provided. The devices and systems include one or more structured tissue augmentation constructs, which include constructs that are configured to increase a footprint across which suture applied force to tissue when the suture is tied down onto the tissue. The tissue augmentation constructs can be quickly and easily associated with the repair suture and can be useful in many different tissue repair procedures that are disclosed in the application. The present disclosure includes structured tissue augmentation blocks for tendon repair that have a flexible or semi-flexible skeleton integrated into the block. The skeleton can be bioabsorbable and can create both in-plane and out-of-plane curvature in the block.
TISSUE THICKNESS COMPENSATOR COMPRISING A RESERVOIR
In various embodiments, a tissue thickness compensator can comprise a compressible extracellular matrix and a bioabsorbable material dispersed within the extracellular matrix, wherein the bioapsorption of the bioabsorbable material is configured to leave behind channels in the extracellular matrix. The tissue thickness compensator can also comprise generation means for generating the ingrowth of tissue into the channels. In at least one embodiment, the tissue thickness compensator can comprise dissolvable wicking members which, when dissolved, can leave behind channels in the tissue thickness compensator. In certain embodiments, the tissue thickness compensator can comprise at least one rupturable capsule.
LUBRICATED MEDICAL INSTRUMENT GUIDE
A medical device includes a medical instrument guide. The medical instrument guide includes a guide body, The guide body includes a foam and a bore through the foam. The foam includes a plurality of open cells that hold a biocompatible lubricant. And, the bore is sized to receive a medical instrument shaft and is defined at least in part by a surface exposing the plurality of open cells holding the biocompatible lubricant to the medical instrument shaft.
Ligature device and method of use
The present invention is an apparatus and method for ligation. The ligation apparatus or band provides topical active agent(s) that alleviate pain during various ligature procedures. This invention also relates to a method that includes applying a loop or band around a body part for elastomeric ligation, whereby the band material supplies a topical active agent (s) to the body part to reduce the pain of ligation.
