RADIAL CUTTER IMPLANT
20230310024 · 2023-10-05 · ·

A method for expanding a constricted location of a urethra of a subject, the method including inserting a urethral implant, and an implant sheath that covers the urethral implant, through the urethra for implanting the urethral implant in the constricted location, the urethral implant being in a compressed configuration within the implant sheath, releasing the urethral implant from the implant sheath until the urethral implant exits from the implant sheath, thereby expanding the urethral implant from the compressed configuration to an expanded configuration, applying, by the urethral implant, continuous pressure on tissues of the urethra at the constricted location, and retracting the implant sheath from the urethra.

Systems, devices, and methods for the accurate deployment and imaging of an implant in the prostatic urethra

Systems, devices, and methods are provided for the delivery of an implant into the prostatic urethra. Embodiments of delivery systems can include a delivery device for insertion into the patient and a proximal control device for use in controlling release of the implant from the delivery device.

Packaging system for ureteral stent

A packaging system for use with a ureteral stent having an elongated shaft extending between a proximal end portion and a distal end portion may include a tray base. The tray base may include at least one first post, a second post, and a projection or a groove configured to respectively secure the distal end portion, the proximal end portion, and a tether of the ureteral stent on the tray base.

Tissue engineering devices and methods employing scaffolds made of absorbable material for use in the human body for tissue genesis and regenerative and cellular medicine including breast reconstruction and cosmetic and aesthetic procedures and supplementing organ function in vivo.

MEDICAL DEVICE WITH ADJUSTABLE LENGTH
20230012922 · 2023-01-19 · ·

An adjustable length medical device, such as a drainage stent, and delivery device for placing within the body, having an elongate tube and retention members at each end portion for anchoring the device in the body. The proximal portion of the device including the proximal retention member may be segmented in incremental portions so that the length of the device can be adjusted for placement.

COIL CATHETER, METHOD OF USE, AND METHOD OF MANUFACTURE
20230010429 · 2023-01-12 ·

A catheter device and manufacturing process for manufacturing the catheter device, wherein the catheter device has a halo-shaped coiled portion extending away from a perpendicular stem portion through a swan neck portion. Eyelets on the halo coil portion and swan neck portion facilitate flow out of the bladder through the catheter device vertical to the catheter, rather than perpendicularly as is the case with existing catheters. The catheter device is formed by using a straight catheter tube, heating and cooling it within a formed mold to have the halo coil and swan neck, such that it can be straightened using a pusher and stylet, inserted into the body while straightened, and thereafter return to its coiled shape when the stylet is removed.

Systems and methods for implants and deployment devices

Benign prosthetic hyperplasia (BPH) is a non-cancerous enlargement of the prostate gland. Treatment options for BPH include medication, surgery (e.g., removal of enlarged prostate tissue), and minimally invasive procedures (e.g., needle ablation, electrovaporization, thermotherapy, and stent insertion). Minimally invasive procedure is typically the preferred choice if medication is ineffective. Accordingly, disclosed herein are system and method for treating BPH using improved implant and delivery device. Certain embodiments of the delivery device can include: a camming barrel having a first groove at the distal end of the camming barrel; a sheath, located within a lumen of the camming barrel, for storing the implantable device; and a first cam follower coupled to the sheath.

Self-expanding devices and methods therefor

Described here are delivery devices for delivering one or more implants to the body, and methods of using. The delivery devices may deliver implants to a variety of locations within the body, for a number of different uses. In some variations, the delivery devices have a cannula with one or more curved sections. In some variations, a pusher may be used to release one or more implants from the cannula. In some variations, one or more of the released implants may be a self-expanding device. Methods of delivering implants to one or more sinus cavities are also described here.

Convertible nephroureteral catheter

A nephroureteral catheter is provided that comprises a detachable portion such that when the detachable portion is removed, the catheter converts into an internal stent. The catheter includes a tube with two retention features, a detachable portion, and an inner tube. The inner tube is removably insertable into both the tube and the detachable portion, and a wire extends through at least a portion of a lumen of the inner tube and through the tube, to keep the pieces attached. The wire may be removed to remove the inner tube and then the detachable portion from the tube. When the detachable portion is attached to the tube, the catheter is a nephroureteral catheter. When the detachable portion is removed from the tube, the catheter becomes a stent.

Compositions and methods for inducing phagocytosis of MHC class I positive cells and countering anti-CD47/SIRPA resistance

Methods and compositions are provided for inducing phagocytosis of a target cell, treating an individual having cancer, treating an individual having an intracellular pathogen infection (e.g., a chronic infection), and/or reducing the number of inflicted cells (e.g., cancer cells, cells infected with an intracellular pathogen, etc.) in an individual. Methods and compositions are also provided for predicting whether an individual is resistant (or susceptible) to treatment with an anti-CD47/SIRPA agent. In some cases, the subject methods and compositions include an anti-MHC Class I/LILRB1 agent. In some cases, the subject methods and compositions include an anti-MHC Class I/LILRB1 agent and an anti-CD47/SIRPA agent (e.g., co-administration of an anti-MHC Class I/LILRB1 agent and an anti-CD47/SIRPA agent). Kits are also provided for practicing the methods of the disclosure.
