Biodegradable scaffold for wound closure including a central rod and upper and lower plates that each at least partially circumscribe the central rod. Each of the upper and lower plates is attached to the central rod and includes an upper section and a lower section that are connected by a helical middle section. The upper section and lower section of the upper plate respectively include first and second bottom surfaces and the upper section and lower section of the lower plate respectively include first and second top surfaces that are respectively spaced apart from and face the first and second bottom surfaces. The first and second bottom surfaces and first and second top surfaces may lie in different planes that are each perpendicular to a central longitudinal axis of the central rod.

Implantable tissue scaffold

Hand held and portable disinfection units for use with patients having indwelling catheters or are hospitalized or under care in an intensive care unit.

Point of care ultraviolet disinfection system

A cryogenic needle of a cryogenic system is coupled to a heater. While the needle is inserted into target tissue beneath skin, the heater provides heat to protect the skin. Power supplied to the heater is used to interpolate performance of the needle and/or operating parameters of the cryogenic system.

Cryogenic needle with freeze zone regulation

A biodegradable scaffold for wound closure including a central rod and two spaced-apart plates. The central rod may have an engagement block on top for stabilizing an implanting tool. The two spaced-apart plates include an upper plate connected to the central rod and a lower plate connected to the central rod. Each of the upper and lower plates may include perforations which may be useful for detachably connecting an implanting tool and which encourage ingrowth of the tissue. The biodegradable scaffold allows tension free anatomic alignment of tissue within the plates and facilitates wound healing. The upper and lower plate may have a helical portion, in which each plate may extend around the central rod. The helical portion serves to draw or pull tissue around the wound defect into the scaffold in the course of deploying the scaffold.

A system for deploying a prosthesis over a Carina between an ipsilateral lumen and a contralateral lumen includes a guidewire, a guidewire capture catheter, a self-expanding tubular prosthesis, and a delivery catheter. The guidewire is first placed in the ipsilateral lumen. The guidewire capture catheter is then advanced from the contralateral lumen to a position at or above the ipsilateral lumen. The guidewire is typically advanced through an occlusion, which may be a total occlusion, and captured by a capture element on the guidewire capture catheter. The guidewire capture catheter pulls the guidewire out through the contralateral side, and the guidewire is used to advance a delivery catheter from the ipsilateral side. The delivery catheter delivers a first segment of the tubular prosthesis in the ipsilateral lumen and a second segment of the prosthesis in the contralateral lumen.

Systems and methods for deploying a luminal prosthesis over a Carina

A biodegradable device for maintaining the alignment of the edges of a trocar defect, consisting of two bases coupled and offset by a connector. The first base to be positioned below the defect and a second base above. The first base has a threaded hole from its upper surface but not through the lower surface. The connector attached to the bases such that there is a hole aligned with the threaded hole in the first base allowing a device to mate with the threads in the first base. The second base has a hole aligned with the hole in the connector and wide enough to allow a device to mate with the threads in the first base. The device is arranged so the distance between the lower surface of the second base and upper surface of the first base holds the fascia around the trocar defect.

Implantable scaffold and method

Cryogenic tissue ablation instruments for treating body tissue include an elongate flexible body with a proximal supply port for coupling with a pressurized coolant (e.g., liquid NO), a supply lumen in fluid communication with the proximal supply port, and an expandable cryogenic balloon carried on a distal portion of the elongate body, the balloon having a wall defining an interior of the balloon. A dispersion member coupled to or otherwise formed out of a distal end portion of the elongate body has an interior lumen in fluid communication with or otherwise comprising a portion of the supply lumen, the dispersion member having one or more coolant dispersion apertures in fluid communication with the balloon interior and sized and located with respect to the balloon wall such that a pressurized flowable coolant in the supply lumen will enter the balloon interior through the one or more apertures in the form of a liquid spray that contacts and provides (through rapid evaporation) substantially uniform cooling of an interior wall surface of a treatment region of the balloon.

Systems and methods for deploying a luminal prosthesis over a carina

A method for maintaining the alignment of the edges of a trocar defect by inserting into a defect a device for compressing the tissue such that part of the device is above while the other is below the defect, then pulling back on the device so that the part below the defect is up against the defect, then while holding the device below the defect in place, push down on the part above the wound so that it compresses the tissue. Finally, release the device from the insertion tool.

Biodegradable apparatus and method for closure of trocar defects

A cryogenic needle probe having a proximal and distal region. A cooling supply tube provides pressurized cooling fluid within the needle. The proximal region is more conductive that the distal region. The proximal region is conductively coupled to a heat source.

Skin protection for subdermal cryogenic remodeling for cosmetic and other treatments

A biodegradable device for providing scaffolding for a trocar defect to promote healing. The device consists of an upper and lower scaffold, offset by a connector. The device is arranged so the distance between the lower surface of the upper scaffolding and upper surface of the lower scaffolding holds the fascia around the trocar defect while promoting tissue growth. The surfaces of the scaffolding in contact with the trocar defect are textured to maximize adherence to tissue.
