Embodiments disclosed herein are directed to an identification insert and assembly alignment feature for a subcutaneous access port. The port can include an identification insert assembled with the device and configured to be visible under medical imaging when placed subcutaneously. The insert can indicate a property of the port and a location or orientation of the port to facilitate access thereto. An alignment feature can be configured to align the insert with the port in a first orientation during manufacture. The alignment feature can also be configured to misalign the insert with the port in a second orientation, different from the first orientation. This can prevent the port from being assembled if the insert is coupled with the port incorrectly. A port having an insert assembled incorrectly can lead to unnecessary disruptions and complications to the patient to correct the problem.
Disclosed herein are systems and methods for providing targeted temperature management (TTM) therapy to a patient. Systems included herein provide an airflow to the patient in additional to a liquid flow that define a thermal energy exchange with the patient. Various systems may provide air at a defined TTM temperature to a thermal contact pad, a mattress or a ventilator that delivers the TTM air to the patient via the ventilation therapy. Also disclosed herein are systems, devices, and methods for preventing, managing, and/or removing perspiration moisture from between the thermal contact pad and the patient. Disclosed herein is a thermal contact pad includes a wicking material to draw moisture away from the patient. Disclosed herein also is a thermal contact pad including airflow that draws moisture away from the patient.

A vascular implant including a tubular body of a polymeric material. The body has opposed filter body ends and a longitudinal axis. The body has a generally tubular segmented side wall that includes multiple spaced apart wall panels surrounding a central open-ended bore. The body includes one or more filtering elements in the bore and in between filter ends. One or more filtering elements including a hub at the central longitudinal axis and multiple radially extending filtering arms extend radially between the hub and wall, wherein each arm connects to a wall panel. The tubular body end has anchors that prevent migration and/or tilting.
Disclosed herein are systems, methods, and apparatuses for obtaining temperature data from a temperature sensing medical instrument. The targeted temperature management (TTM) system includes a TTM module configured to provide a TTM fluid, a thermal pad configured to receive the TTM fluid from the TTM module to facilitate thermal energy transfer between the TTM fluid and a patient, a fluid delivery line (FDL) extending between the TTM module and the thermal pad, the FDL configured to provide TTM fluid flow between the TTM module and the thermal pad, and a temperature sensing medical instrument configured to be inserted into the patient and obtain temperature data indicating a temperature of blood of the patient, wherein the temperature sensing medical instrument is further configured to communicatively couple to the TTM module and provide the TTM module with temperature feedback including the temperature of the blood of the patient.
Push activated intraosseous (IO) access devices include power sources such as battery packs or spring driven devices. Intraosseous access devices often require training to ensure correct placement of the access device. The disclosed devices include an intuitive operation with a unidirectional activation and drive force application. The trigger can be both activated and deactivated automatically to prevent premature activation and prevent “backwalling”. The device can include various indicators to further guide a user in placing the device correctly, with little or no training. Devices can further include replaceable battery packs to ensure a full charge is available when the device is used, and to provide a multi-use device that requires less storage.

HANDLE ASSEMBLIES FOR MEDICAL DEVICES AND METHODS OF ASSEMBLING THE SAME
A handle assembly for a medical device includes a proximal handle assembly that includes a proximal rotational shaft portion and a proximal magnetic disk mounted to the proximal rotational shaft portion, the proximal magnetic disk including one or more proximal interlock features. The medical device also includes a distal handle assembly that includes a distal rotational shaft portion and a distal magnetic disk mounted to the distal rotational shaft portion, the distal magnetic disk including one or more distal interlock features. The proximal magnetic disk and the distal magnetic disk interlock with one another via interaction of the one or more proximal interlock features and the one or more distal interlock features.
A61B 17/22 - Implements for squeezing-off ulcers or the like on inner organs of the bodyImplements for scraping-out cavities of body organs, e.g. bonesSurgical instruments, devices or methods for invasive removal or destruction of calculus using mechanical vibrationsSurgical instruments, devices or methods for removing obstructions in blood vessels, not otherwise provided for
A biopsy device includes a reusable assembly that includes an outer housing and a plunger lock mechanism located in the outer housing. The plunger lock mechanism includes an actuation member accessible outside the outer housing that moves relative to the outer housing and includes a cam surface. A release flange is configured to move axially in the outer housing and includes a follower surface. A gripping finger is configured to move laterally with axial movement of the release flange. The cam and follower surfaces are configured to cooperate such that movement of the actuation member relative to the outer housing moves the release flange axially relative to the gripping finger. The release flange is configured to move the gripping finger from a locked configuration engaged with a plunger of a syringe to an unlocked configuration disengaged with the plunger of the syringe.
A composite medical balloon (10) includes a base balloon (100) and an outer layer (16) overlying the base balloon, the outer layer comprising a film having a single longitudinal seam (80), or a longitudinal seam facing the base balloon, such as a result of a tube including the seam being everted prior to application to the base balloon.
