Embodiments provide apparatus and methods for delivering liquid form medication within the body wherein the medication is stored in solid form and then mixed with a liquid in an apparatus implanted within the body. One embodiment provides an implantable apparatus for in vivo delivery of medication comprising a housing including a reservoir, a store of solid form medication (SSM) and a pump. An SSM element is added to the reservoir along with fluid to form a medication solution comprising at least one drug. The medication solution is then delivered to a delivery site using a pumping means to pump solution from the reservoir through a delivery member such as catheter to a delivery site. Embodiments of the invention are particularly useful for delivering medication to a patient to treat a medical condition over an extended period of time without requiring the patient to take external medication.

The diagnostic vascular window may, for example, be used pre-surgery, during surgery, and post-surgery to determine whether a correct type and dose of diuretic drugs are being used for the patient. The diagnostic vascular window utilizes low flow accesses to view blood/fluids leaving and entering the patient's body. In addition, the same amount of fluids leaving the body enters the body, so there are no fluid losses or gains within the diagnostic vascular window. The low flow accesses in conjunction with a monitoring system allows for real-time measurements of blood parameters without fluid loss.

The Brain Portal is a device that allows for easy access to the brain for treatments that require multiple visits inside the brain case to alleviate the need for multiple craniotomies. Such treatments could involve multiple injections of medicines that have to be given over a period of days or weeks. In a different configuration, it also allows for electrical stimulation of the brain thru electrodes without the need for batteries, and allows the flow of electricity from outside the brain to the affected areas using induction coils. The Brain Portal can also be used as an easy means to collect samples of cerebral spinal fluid without the need of a spinal tap. Furthermore, having an easy access allows the physician the option of injecting drugs directly into the brain, bypassing the blood-brain barrier, thereby lowering the dosage needed to treat disease.

Номер: US20180008798A1
Принадлежит: Fresenius Medical Care Holdings Inc

A device and method for holding coils of medical tubing is provided to simplify packaging and organizing the various coils of medical tubing needed for a medical device. This will make it easier for the patient to manipulate each coil of tubing, particularly in a home setting involving a home dialysis machine operated by the patient. The tube holding device advantageously reduces the probability of entanglement and groups the coils of tubing individually. It also mitigates and/or eliminates the need for tape to bundle the coils. Specifically, benefits of the tube holding device according to the system described herein include: reduced cost; ease-of-use; prevention of entanglement of coils of tubing; ease of packaging and shipping; and does not require packaging tape to bundle tubing.
