A collection device for collecting and preserving biological material. A longitudinal shaft is provided with a proximal end and a distal end. An absorbent solid matrix having at least one layer of chemically impregnated filter paper is affixed to the distal end of the shaft. The absorbent solid matrix consists of chemically impregnated filter paper and can have portions separated by perforations, or an inner core and a separable, overlapping outer layer. The absorbent solid matrix has a configuration that may include nubs, individual ribs, helical, filaments, and radial protrusions. Also disclosed is a tampon-like collection device for delivering an absorbent solid matrix.

This invention relates to medical, health care and non-medical devices comprising a rubbery or elastomeric polymer material taking up more than 5% by weight of water and at most 500% by weight of water after immersion in demineralized water at room temperature for a sufficient time to reach saturation. The material may be in the form of a foam, or in the form of a coating adapted for adhesion to a substrate, or in the form of a sheet, or in the form of a fiber, and may comprise: —repeating units from one or more hydrophobic organic monomers, and —repeating units from one or more monomers (a) being modified with one or more hydrophilic side groups.

Uterine hemostasis devices and related methods are generally described. In some embodiments, a uterine hemostasis device may include a pouch enclosing one or more fluid absorbing bodies for treatment of postpartum hemorrhage. The pouch may be delivered to a patient's uterus, whereby the fluid absorbing bodies may absorb uterine fluids (e.g., blood) and expand to apply pressure to the uterine walls. Following hemostasis of the uterus, the pouch may be extracted with retrieval tethers accessible from the patient's vagina or vaginal opening. In some embodiments, the pouch may be compressed prior to extraction, such that it may pass through the cervical canal more easily. In some embodiments, the pouch may enclose one or more pouches, such that the fluid absorbing bodies may be extracted in batches to facilitate removal. The pouch may be delivered with a syringe-like applicator positioned in the cervical canal.

In one example, a medical system may comprise a delivery tube configured to couple to a vacuum source and provide negative pressure to a distal portion of the delivery tube; and a porous body at a distal portion of the delivery tube, the porous body including a first section and a second section removable from the first section.

The present invention relates to methods of obtaining a biological sample from the vagina and detecting various conditions (e.g., detecting a sexually transmitted infection, determining the composition of the vaginal microbiome, and detecting dysbiosis) using a tampon. The present invention also relates to kits containing a tampon for use in such methods.

Disclosed are solid and frozen haemostatic materials having a rod shape and suitable applicators and plungers for application of such dressings to wounded tissue wherein said dressings consisting essentially of a fibrinogen component and a fibrinogen activator. Also disclosed are methods of treating internal wounded tissue in a mammal by applying one or more of these haemostatic materials and dressings, particularly for the treatment of injured tissue via endoscopic or minimally-invasive surgical techniques.

In one example, a medical system may comprise a delivery tube configured to couple to a vacuum source and provide negative pressure to a distal portion of the delivery tube; and a porous body at a distal portion of the delivery tube, the porous body including a first section and a second section removable from the first section.

Negative pressure therapy systems are provided for increasing urine production, the negative pressure therapy system including: (a) a pump assembly, the pump assembly including: (i) a pump configured to provide negative pressure to a kidney, and (ii) a controller configured to regulate the negative pressure provided by the pump within a pressure range that facilitates increased urine production from the kidney.

A haemostatic composition comprising a non-acidic meshed network of fibrous material, wherein the network comprises fibres with a mean diameter (Dso) no greater than 1 μm, an aspect ratio (mean fibre length/mean fibre diameter) of at least 100, and wherein said meshed network has a specific surface area of at least 1O m.sup.2/g, and a gel point no greater than 3 g/L.

A pump for inducing negative pressure in the ureter and/or kidney is provided. The pump is configured to be in communication with at least one lumen of at least one ureteral catheter and to draw fluid from the ureter and/or kidney into the at least one lumen of the at least one ureteral catheter for removal of the fluid from the ureter and/or kidney. The pump is configured to induce negative pressure ranging from about 0.1 mmHg to about 50 mmHg gauge pressure proximate to the pump inlet, and the pump is configured to have an accuracy of about 10 mmHg or less proximate to the pump inlet.
