The present invention relates to the intrathecal (IT) administration of recombinant enzyme to treat lysosomal storage disorders. In an exemplary embodiment, intrathecal administration of human α-L-iduronidase (rhIDU) injections in MPS I affected animals resulted in significant enzyme uptake, significant rh-iduronidase activity in brain and meninges and a decrease of glycosaminoglycan (GAG) storage in cells of MPS I subjects to that of normal subjects. Intrathecal administration proved more effective than intravenous treatment at alleviating MPS I symptoms, indicating it is a useful method of treating lysosomal storage disorders.

An infusion and blood collection device allows clean blood collections into a collection tube via a previously installed angiocatheter without interrupting the administration of intravenous therapies after initial installation. The device optionally includes passive control of the blood collection flow rate to prevent contamination of the collected blood draw with the IV therapy fluid being simultaneously infused through the angiocatheter. A blood collection method uses an infusion and blood collection device to draw a clean blood sample from a patient and into a collection tube via a previously installed angiocatheter without interrupting the administration of intravenous therapies.

Disclosed is a physiological approach of a penile venous stripping surgical procedure for patients with erectile dysfunction (ED), which mainly contains a revolutionary surgical solution of treating leakage veins for restoring erectile function based on a template of penile tunical and venous anatomy. The method entails a thorough penile venous stripping and then being ligated of one deep dorsal vein and a pair of cavernosal veins whereas two pairs of para-arterial veins are rendered for segmental ligation rather than being stripped closest to the tunica albuginea by using a set of specific instruments under an acupuncture-aided local anesthesia on an ambulatory basis. Although the techniques for handling venous tissues with stripping and then ligation is extraordinarily challenging, this innovative method turns the venous treatment for ED from one that has been abandoned to a curable option.

A multiport infusion device used as an intravenous administrator of prescribed fluid is provided. The device includes a band adapted to be secured to a user's body part near an intravenous therapy location. A multiport body is secured to the band and includes a multiport fluid exchange route fluidly communicating between a first port and at least a second port of the body's ports.

The invention refers to tumor-homing cells expressing the tumor necrosis factor-related apoptosis inducing ligand (TRIAL), particularly to CD34+ and NK cells transduced with adenoviral vectors coding for TRIAL. The cells of the invention are useful for the intravenous treatment of tumors, particularly of lymphoma.

There is provided herein a system, device and methods for performing minimally invasive spider vein treatments. In some embodiments an apparatus for eliminating spider veins comprises a dual syringe mechanism that includes a pusher for pushing sclerosant materials into a target vein, and an extractor for extracting debris from a target vein; a needle for application into a target vein; and a Y-connector connecting each exit of the dual syringe mechanism to the needle. In some implementations the apparatus's dual syringe mechanism includes a locking mechanism to enable controlled advancing of the syringe pusher.

A vapor delivery and insulation device is provided that may include any of a plurality of features. One feature of the device is that it can deliver vapor to the veins of a patient. The vapor can be generated within the device, in a handle of the device, or external to the device. Another feature of the device is that it can actively insulate the vapor to minimize heat transfer from a vapor delivery lumen of the device to an exterior surface of the device. The active insulation can be a vacuum or a flowing gas. Methods associated with use of the device are also covered.

A device, apparatus and method are provided to implement minimally invasive perforating vein treatment, the apparatus including a vein ablation blocking element, to be deployed downstream from the vein ablation apparatus, before a deep vein junction, to prevent passage to a downstream deep vein; and an anchoring mechanism, to anchor the vein ablation apparatus into the perforating vein wall(s), to prevent movement of the vein ablation apparatus after deployment.

Methods and apparatus for generating vapor within a catheter are provided which may include any number of features. One feature is generating vapor with an electrode array within a catheter. Another feature is sensing an impedance of the electrode array, and adjusting the power delivered to the electrode array to fully generate vapor within the catheter. Another feature is delivering the vapor to a vein of a patient for vein reduction therapy.

The invention discloses a soft infusion bag and a flushing method, which relate to the technical field of medical devices, solve the problem that the use of the existing soft infusion bag requires multiple sharps exposure and puncture, exists the risk of bacterial contamination, and does not conform to the safety concept of modern intravenous therapy and nursing. , including issues of patient safety and occupational exposure safety of healthcare workers. The technical scheme adopted is: an infusion soft bag, including a bag body, the bag body is divided into a liquid medicine bag and a flushing liquid bag, a drug adding pipe is arranged on the liquid medicine bag, a liquid medicine outlet at the bottom of the liquid medicine bag and a flushing liquid bag at the bottom of the washing liquid bag. The liquid outlet is connected to both ends of the tee through a conduit, the other end of the tee is connected to an infusion pipe, and a switch is arranged between the flushing liquid outlet and the tee. First keep the switch between the flushing liquid outlet and the three-way closed. After the liquid bag is infused, turn on the switch to flush. The flushing process does not require sharp puncture, which reduces the exposure of sharps and enhances safety; the flushing dosage can be adjusted to avoid drug compatibility reactions between groups, and to ensure accurate dosage of medication.
